I am calling python script from c# using ProcessInfoStart method. As an argument it receives JSON and is input to python script.
It works fine it we pass JSON without having any spaces but if there is any space then original JSON is splitted till space and passes as argument and rest ignored
public static bool ExecutePythonScript(string jRequest, string fileType)
{
string pythonExePath = Convert.ToString(ConfigurationManager.AppSettings["PythonExe"]);
bool bIsExecutionSuccess = true;
try
{
var psi = new ProcessStartInfo();
psi.FileName = pythonExePath;
var script = #"C:Scripts\pdf-to-csv.py";
psi.Arguments = $"\"{script}\" \"{jRequest}\"";
psi.UseShellExecute = false;
psi.CreateNoWindow = true;
psi.RedirectStandardOutput = true;
psi.RedirectStandardError = true;
var errors = "";
var results = "";
using (var process = Process.Start(psi))
{
errors = process.StandardError.ReadToEnd();
results = process.StandardOutput.ReadToEnd();
}
if (!string.IsNullOrEmpty(errors))
bIsExecutionSuccess = false;
}
catch(Exception ex)
{
bIsExecutionSuccess = false;
}
return bIsExecutionSuccess;
}
Python script to accept arguments
input_params = sys.argv[1]
input_params = input_params.replace("'",'"')
data_params = json.loads(input_params)
Is there a way i can pass jRequest with spaces to python script.
Python script parameters can be wrapped in single quotes in order to read the whole string including spaces.
Try wrapping the JSON string in single quotes.

I am creating a web application using ASP NET that runs on Windows Server 2012 using IIS 10. This application exposes a service at www.domain.com/service/execute which uses a python script executed using Python 3.9.13. Below I report the C# and Python code:
main.py
import pprint
pprint.pprint("Hello World!!")
ServiceController.cs
public class ServiceController : Controller {
public IActionResult Execute() {
var FileName = $#"C:\\path\\to\\python.exe";
var Arguments = $#"C:\\path\\to\\main.py";
var processStartInfo = new ProcessStartInfo() {
FileName = FileName,
Arguments = Arguments,
CreateNoWindow = true,
UseShellExecute = false,
RedirectStandardOutput = true,
RedirectStandardError = true,
};
using(var process = Process.Start(processStartInfo)) {
var taskError = process.StandardError.ReadToEndAsync();
var taskOutput = process.StandardOutput.ReadToEndAsync();
taskError.Wait();
taskOutput.Wait();
var errors = taskError.Result.Trim();
var output = taskOutput.Result.Trim();
return Ok(
$"FileName={FileName}" +
$"\n" +
$"Arguments={Arguments}" +
$"\n" +
$"errors={errors}" +
$"\n" +
$"output={output}"
);
}
}
}
Calling this service I don't get any errors or exceptions but the output is empty:
FileName=C:/path/to/python.exe
Arguments=C:/path/to/main.py
errors=
output=
If in the C# script I insert as Arguments a totally invented path to a non-existent python script I don't get any error/exception and the output is still empty.
I would expect an output like this:
FileName=C:/path/to/python.exe
Arguments=C:/path/to/main.py
errors=
output=Hello World!!
I want to run .py file from my C# project, and get the result. The python script is making an API request, and returns an auth_key token, which I want to use in my C# code. The only problem is that, for some reason the C# code doesn't wait for the process to finish, and thus that not every account has auth_key. Here is my C# code.
private static void GenerateTokens()
{
var url = ConfigurationManager.AppSetting[GeSettingsNode() + ":ip"];
for (int i = 0; i < accounts.Count; i++)
{
ProcessStartInfo start = new ProcessStartInfo();
start.FileName = ConfigurationManager.AppSetting["PythonPath"];
start.Arguments = string.Format($"python_operation_processor.py {accounts[i].client_key_id} {accounts[i].key_sercret_part} {url}");
start.UseShellExecute = false;
start.RedirectStandardOutput = true;
Process process = Process.Start(start);
using (StreamReader reader = process.StandardOutput)
{
accounts[i].auth_key = reader.ReadToEnd().Trim();
}
}
}
And here is my Python script ( python_operation_processor.py )that's making the API requests.
if __name__ == '__main__':
client_key_id = sys.argv[1]
client_secret = sys.argv[2]
API_URL = sys.argv[3]
nonce = str(uuid.uuid4())
d = datetime.datetime.now() - datetime.timedelta(hours=3)
timestamp = d.strftime('%Y-%m-%dT%H:%M:%S.%f')[:-3] + 'Z'
signature = b64encode(hmac.new(b64decode(client_secret), msg=bytes(client_key_id + nonce + timestamp, 'utf-8'),
digestmod=hashlib.sha256).digest()).decode('utf-8')
r = requests.post(API_URL + '/v1/authenticate',
json={'client_key_id': client_key_id, 'timestamp': timestamp, 'nonce': nonce,
'signature': signature})
if r.status_code != 200:
raise Exception('Failed to authenticate: ' + r.text)
auth_token = r.json()['token']
print(auth_token)
Do you have any idea, how I can wait for the execution of every process, and get the token for every account ?
I recently created something similar and ended up with this because, whilst waiting for the process is easy, it is tricky to get the output stream filled correctly.
The method presented also allow you to display the output into a textblock or similar in your application.
If you use it like this, the token will be written to the StringBuilder, and used as return value.
private async Task<string> RunCommand(string fileName, string args)
{
var timeoutSignal = new CancellationTokenSource(TimeSpan.FromMinutes(3));
ProcessStartInfo start = new ProcessStartInfo();
start.FileName = fileName;
start.Arguments = string.Format("{0}", args);
start.RedirectStandardOutput = true;
start.RedirectStandardError = true;
start.UseShellExecute = false;
start.CreateNoWindow = true;
var sb = new StringBuilder();
using (Process process = new Process())
{
process.StartInfo = start;
process.OutputDataReceived += (sender, eventArgs) =>
{
sb.AppendLine(eventArgs.Data); //allow other stuff as well
};
process.ErrorDataReceived += (sender, eventArgs) => {};
if (process.Start())
{
process.EnableRaisingEvents = true;
process.BeginOutputReadLine();
process.BeginErrorReadLine();
await process.WaitForExitAsync(timeoutSignal.Token);
//allow std out to be flushed
await Task.Delay(100);
}
}
return sb.ToString();
}
To render this to a textblock in a UI application, you'll need to:
implement an event which signals a new line has been read, which means forwarding the process.OutputDataReceived event.
if your thinking about a live feed, make sure you flush the stdio buffer in python setting flush to true: print(""hello world"", flush=True)
If you're using an older .net version; you can implement the WaitForExitAsync as described here: https://stackoverflow.com/a/17936541/2416958 as an extention method:
public static class ProcessHelpers
{
public static Task<bool> WaitForExitAsync(this Process process, TimeSpan timeout)
{
ManualResetEvent processWaitObject = new ManualResetEvent(false);
processWaitObject.SafeWaitHandle = new SafeWaitHandle(process.Handle, false);
TaskCompletionSource<bool> tcs = new TaskCompletionSource<bool>();
RegisteredWaitHandle registeredProcessWaitHandle = null;
registeredProcessWaitHandle = ThreadPool.RegisterWaitForSingleObject(
processWaitObject,
delegate(object state, bool timedOut)
{
if (!timedOut)
{
registeredProcessWaitHandle.Unregister(null);
}
processWaitObject.Dispose();
tcs.SetResult(!timedOut);
},
null /* state */,
timeout,
true /* executeOnlyOnce */);
return tcs.Task;
}
}
I would like to call a python script in my C# project , I'm using this function to do the job but unfortunately I didn't get any result and the result variable shows always an empty output. I would like to know what's the reason of this
public string RunFromCmd(string rCodeFilePath, string args)
{
string file = rCodeFilePath;
string result = string.Empty;
try
{
var info = new ProcessStartInfo(pythonPath);
info.Arguments = #"C:\Users\MyPc\ExternalScripts\HelloWorld.py" + " " + args;
info.RedirectStandardInput = false;
info.RedirectStandardOutput = true;
info.UseShellExecute = false;
info.CreateNoWindow = true;
using (var proc = new Process())
{
proc.StartInfo = info;
proc.Start();
proc.WaitForExit();
if (proc.ExitCode == 0)
{
result = proc.StandardOutput.ReadToEnd();
}
}
return result;
}
catch (Exception ex)
{
throw new Exception("R Script failed: " + result, ex);
}
}
Click Event ( Calling funtion )
private void Button1_Click(object sender, RoutedEventArgs e)
{
pythonPath = Environment.GetEnvironmentVariable("PYTHON_PATH");
RunFromCmd(pythonPath, "");
}
Python Script :
import sys
def main():
text = "Hello World"
return text
result = main()
I've fixed the issue by setting Copy if newer instead of Do Not Copy to HelloWorld.py Script
Thanks to this great answer I was able to figure out how to run a preflight check for my documents using Python and the InDesign script API. Now I wanted to work on automatically adjusting the text size of the overflowing text boxes, but was unable to figure out how to retrieve a TextBox object from the Preflight object.
I referred to the API specification, but all the properties only seem to yield strings which do not uniquely define the TextBoxes, like in this example:
Errors Found (1):
Text Frame (R=2)
Is there any way to retrieve the violating objects from the Preflight, in order to operate on them later on? I'd be very thankful for additional input on this matter, as I am stuck!
If all you need is to find and to fix the overset errors I'd propose this solution:
Here is the simple Extendscript to fix the text overset error. It decreases the font size in the all overflowed text frames in active document:
var doc = app.activeDocument;
var frames = doc.textFrames.everyItem().getElements();
var f = frames.length
while(f--) {
var frame = frames[f];
if (frame.overflows) resize_font(frame)
}
function resize_font(frame) {
app.scriptPreferences.enableRedraw = false;
while (frame.overflows) {
var texts = frame.parentStory.texts.everyItem().getElements();
var t = texts.length;
while(t--) {
var characters = texts[t].characters.everyItem().getElements();
var c = characters.length;
while (c--) characters[c].pointSize = characters[c].pointSize * .99;
}
}
app.scriptPreferences.enableRedraw = true;
}
You can save it in any folder and run it by the Python script:
import win32com.client
app = win32com.client.Dispatch('InDesign.Application.CS6')
doc = app.Open(r'd:\temp\test.indd')
profile = app.PreflightProfiles.Item('Stackoverflow Profile')
print('Profile name:', profile.name)
process = app.PreflightProcesses.Add(doc, profile)
process.WaitForProcess()
errors = process.processResults
print('Errors:', errors)
if errors[:4] != 'None':
script = r'd:\temp\fix_overset.jsx' # <-- here is the script to fix overset
print('Run script', script)
app.DoScript(script, 1246973031) # run the jsx script
# 1246973031 --> ScriptLanguage.JAVASCRIPT
# https://www.indesignjs.de/extendscriptAPI/indesign-latest/#ScriptLanguage.html
process = app.PreflightProcesses.Add(doc, profile)
process.WaitForProcess()
errors = process.processResults
print('Errors:', errors) # it should print 'None'
if errors[:4] == 'None':
doc.Save()
doc.Close()
input('\nDone... Press <ENTER> to close the window')
Thanks to the exellent answer of Yuri I was able solve my problem, although there are still some shortcomings.
In Python, I load my documents and check if there are any problems detected during the preflight. If so, I move on to adjusting the text frames.
myDoc = app.Open(input_file_path)
profile = app.PreflightProfiles.Item(1)
process = app.PreflightProcesses.Add(myDoc, profile)
process.WaitForProcess()
results = process.processResults
if "None" not in results:
# Fix errors
script = open("data/script.jsx")
app.DoScript(script.read(), 1246973031, variables.resize_array)
process.WaitForProcess()
results = process.processResults
# Check if problems were resolved
if "None" not in results:
info_fail(card.name, "Error while running preflight")
myDoc.Close(1852776480)
return FLAG_PREFLIGHT_FAIL
I load the JavaScript file stored in script.jsx, that consists of several components. I start by extracting the arguments and loading all the pages, since I want to handle them individually. I then collect all text frames on the page in an array.
var doc = app.activeDocument;
var pages = doc.pages;
var resizeGroup = arguments[0];
var condenseGroup = arguments[1];
// Loop over all available pages separately
for (var pageIndex = 0; pageIndex < pages.length; pageIndex++) {
var page = pages[pageIndex];
var pageItems = page.allPageItems;
var textFrames = [];
// Collect all TextFrames in an array
for (var pageItemIndex = 0; pageItemIndex < pageItems.length; pageItemIndex++) {
var candidate = pageItems[pageItemIndex];
if (candidate instanceof TextFrame) {
textFrames.push(candidate);
}
}
What I wanted to achieve was a setting where if one of a group of text frames was overflowing, the text size of all the text frames in this group are adjusted as well. E.g. text frame 1 overflows when set to size 8, no longer when set to size 6. Since text frame 1 is in the same group as text frame 2, both of them will be adjusted to size 6 (assuming the second frame does not overflow at this size).
In order to handle this, I pass an array containing the groups. I now check if the text frame is contained in one of these groups (which is rather tedious, I had to write my own methods since InDesign does not support modern functions like filter() as far as I am concerned...).
// Check if TextFrame overflows, if so add all TextFrames that should be the same size
for (var textFrameIndex = 0; textFrameIndex < textFrames.length; textFrameIndex++) {
var textFrame = textFrames[textFrameIndex];
// If text frame overflows, adjust it and all the frames that are supposed to be of the same size
if (textFrame.overflows) {
var foundResizeGroup = filterArrayWithString(resizeGroup, textFrame.name);
var foundCondenseGroup = filterArrayWithString(condenseGroup, textFrame.name);
var process = false;
var chosenGroup, type;
if (foundResizeGroup.length > 0) {
chosenGroup = foundResizeGroup;
type = "resize";
process = true;
} else if (foundCondenseGroup.length > 0) {
chosenGroup = foundCondenseGroup;
type = "condense";
process = true;
}
if (process) {
var foundFrames = findTextFramesFromNames(textFrames, chosenGroup);
adjustTextFrameGroup(foundFrames, type);
}
}
}
If this is the case, I adjust either the text size or the second axis of the text (which condenses the text for my variable font). This is done using the following functions:
function adjustTextFrameGroup(resizeGroup, type) {
// Check if some overflowing textboxes
if (!someOverflowing(resizeGroup)) {
return;
}
app.scriptPreferences.enableRedraw = false;
while (someOverflowing(resizeGroup)) {
for (var textFrameIndex = 0; textFrameIndex < resizeGroup.length; textFrameIndex++) {
var textFrame = resizeGroup[textFrameIndex];
if (type === "resize") decreaseFontSize(textFrame);
else if (type === "condense") condenseFont(textFrame);
else alert("Unknown operation");
}
}
app.scriptPreferences.enableRedraw = true;
}
function someOverflowing(textFrames) {
for (var textFrameIndex = 0; textFrameIndex < textFrames.length; textFrameIndex++) {
var textFrame = textFrames[textFrameIndex];
if (textFrame.overflows) {
return true;
}
}
return false;
}
function decreaseFontSize(frame) {
var texts = frame.parentStory.texts.everyItem().getElements();
for (var textIndex = 0; textIndex < texts.length; textIndex++) {
var characters = texts[textIndex].characters.everyItem().getElements();
for (var characterIndex = 0; characterIndex < characters.length; characterIndex++) {
characters[characterIndex].pointSize = characters[characterIndex].pointSize - 0.25;
}
}
}
function condenseFont(frame) {
var texts = frame.parentStory.texts.everyItem().getElements();
for (var textIndex = 0; textIndex < texts.length; textIndex++) {
var characters = texts[textIndex].characters.everyItem().getElements();
for (var characterIndex = 0; characterIndex < characters.length; characterIndex++) {
characters[characterIndex].setNthDesignAxis(1, characters[characterIndex].designAxes[1] - 5)
}
}
}
I know that this code can be improved upon (and am open to feedback), for example if a group consists of multiple text frames, the procedure will run for all of them, even though it need only be run once. I was getting pretty frustrated with the old JavaScript, and the impact is negligible. The rest of the functions are also only helper functions, which I'd like to replace with more modern version. Sadly and as already stated, I think that they are simply not available.
Thanks once again to Yuri, who helped me immensely!
I have searched, copied and modified code, and tried to break down what others have done and I still can't get this right.
I have email receipts for an ecommerce webiste, where I am trying to harvest particular details from each email and save to a spreadsheet with a script.
Here is the entire script as I have now.
function menu(e) {
var ui = SpreadsheetApp.getUi();
ui.createMenu('programs')
.addItem('parse mail', 'grabreceipt')
.addToUi();
}
function grabreceipt() {
var ss = SpreadsheetApp.getActiveSheet();
var ss = SpreadsheetApp.getActiveSpreadsheet();
var s = ss.getSheetByName("Sheet1");
var threads = GmailApp.search("(subject:order receipt) and (after:2016/12/01)");
var a=[];
for (var i = 0; i<threads.length; i++)
{
var messages = threads[i].getMessages();
for (var j=0; j<messages.length; j++)
{
var messages = GmailApp.getMessagesForThread(threads[i]);
for (var j = 0; j < messages.length; j++) {
a[j]=parseMail(messages[j].getPlainBody());
}
}
var nextRow=s.getDataRange().getLastRow()+1;
var numRows=a.length;
var numCols=a[0].length;
s.getRange(nextRow,1,numRows,numCols).setValues(a);
}
function parseMail(body) {
var a=[];
var keystr="Order #,Subtotal:,Shipping:,Total:";
var keys=keystr.split(",");
var i,p,r;
for (i in keys) {
//p=keys[i]+(/-?\d+(,\d+)*(\.\d+(e\d+)?)?/);
p=keys[i]+"[\r\n]*([^\r^\n]*)[\r\n]";
//p=keys[i]+"[\$]?[\d]+[\.]?[\d]+$";
r=new RegExp(p,"m");
try {a[i]=body.match(p)[1];}
catch (err) {a[i]="no match";}
}
return a;
}
}
So the email data to pluck from comes as text only like this:
Order #89076
(body content, omitted)
Subtotal: $528.31
Shipping: $42.66 via Priority Mail®
Payment Method: Check Payment- Money order
Total: $570.97
Note: mywebsite order 456. Customer asked about this and that... etc.
The original code regex was designed to grab content, following the keystr values which were easily found on their own line. So this made sense:
p=keys[i]+"[\r\n]*([^\r^\n]*)[\r\n]";
This works okay, but results where the lines include more data that follows as in line Shipping: $42.66 via Priority Mail®.
My data is more blended, where I only wish to take numbers, or numbers and decimals. So I have this instead which validates on regex101.com
p=keys[i]+"[\$]?[\d]+[\.]?\d+$";
The expression only, [\$]?[\d]+[.]?\d+$ works great but I still get "no match" for each row.
Additionally, within this search there are 22 threads returned, and it populates 39 rows in the spreadsheet. I can not figure out why 39?
The reason for your regex not working like it should is because you are not escaping the "\" in the string you use to create the regex
So a regex like this
"\s?\$?(\d+\.?\d+)"
needs to be escaped like so:
"\\s?\\$?(\\d+\\.?\\d+)"
The below code is just modified from your parseEmail() to work as a snippet here. If you copy this to your app script code delete document.getElementById() lines.
Your can try your example in the snippet below it will only give you the numbers.
function parseMail(body) {
if(body == "" || body == undefined){
var body = document.getElementById("input").value
}
var a=[];
var keystr="Order #,Subtotal:,Shipping:,Total:";
var keys=keystr.split(",");
var i,p,r;
for (i in keys) {
p=keys[i]+"\\s?\\$?(\\d+\\.?\\d+)";
r=new RegExp(p,"m");
try {a[i]=body.match(p)[1];}
catch (err) {a[i]="no match";}
}
document.getElementById("output").innerHTML = a.join(";")
return a;
}
<textarea id ="input"></textarea>
<div id= "output"></div>
<input type = "button" value = "Parse" onclick = "parseMail()">
Hope that helps
