Im trying to write a python script that basically interacts with a webservice that uses an xml api. The request method is POST.
Usually I would write a request of the form request(url, data, headers) - however, in the case of an xml api it would not work. Also something like data.encode('utf-8') or urllib.urlencode(data) would not work as the data is not a dict.
In this case, data is xml so how am i supposed to sent it over?
[EDIT]
When I send a string of XML I get a urllib2.HTTPError: HTTP Error 415: Unsupported Media Type Exception. Is there any other way I'm supposed to send the data?
Also, the API I am using the Google Contacts API. I'm trying to write a script that adds a contact to my gmail account.
You probably need to set proper Content-Type header, for XML it would probably be:
application/xml
So something like this should get you going:
request = urllib2.Request( 'xml_api.example.com' )
request.add_header('Content-Type', 'application/xml')
response = urllib2.urlopen(request, xml_data_string)
Hope that helps :)

I am just trying to access an API through Postman and its wokring fine.The Postman header response is returning some details like below
Authentication-Token →/DwG7gAxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
Connection →keep-alive
Content-Length →16
Content-Type →application/json;charset=UTF-8
Date →Tue, 25 Sep 2018 17:44:01 GMT
Server →Apache-Coyote/1.1
But when I am trying to do same in Python I am just receivig the response status.(200)
How can I get the above Authentication-Token etc details like Postman in python code.
import requests
import json
url = 'https://test-orchestrator.lmig.com/baocdp/rest/login/'
headers = {"Content-Type": "application/json"}
data1 = {"username":"abc", "password":"abc"}
print("Testing authentication for Remedy test environment...")
change_response=requests.post(url,data=json.dumps(data1),headers=headers)
print(change_response)
If you print change_response, it will most likely look like this <status [200]> or something to that effect. If you want to see the contents of the response, you can use the vars response.text, response.content, or response.headers (among others) or since this is a json response, you can use the method response.json() to convert the contents of the response into a dictionary full of native Python data types.
I would reccommend x = response.json(), as the contents of your response seem to contain an auth token that you will most likely need to communicate with this device further. You can then use auth+token = x[token_key] to isolate that token.
from suds.client import Client
url = r'http://*********?singleWsdl'
c = Client(url)
The requests work fine till here, but when I execute the below statement, I get the error message shown at the end. Please help.
c.service.Method_Name('parameter1', 'parameter2')
The Error message is :
Exception: (415, u'Cannot process the message because the content type
\'text/xml; charset=utf-8\' was not the expected type
\'multipart/related; type="application/xop+xml"\'.')
A Content-Type header of multipart/related; type="application/xop+xml" is the type used by MTOM, a message format used to efficiently send attachments to/from web services.
I'm not sure why the error claims to be expecting it, because the solution I found for my situation was the override the Content-Type header to 'application/soap+xml;charset=UTF-8'.
Example:
soap_client.set_options(headers = {'Content-Type': 'application/soap+xml;charset=UTF-8'})
If you are able, you could also trying checking for MTOM encoding in the web service's configuration and changing it.
I am trying to add a lead to a Zoho CRM module with Python. I keep getting:
< response>< error>< code>4600< /code>< message>Unable to process your request. Please verify if the name and value is appropriate for the "xmlData" parameter.< /message>< /error>< /response>
from the server. I have no idea if I am posting correctly or if it is a problem with our Xml Data. I am using urllib and urllib2 to format the post request.
The post request looks like this.
url = ("https://crm.zoho.com/crm/private/xml/Leads/insertRecords?authtoken="
""+str(self.authToken)+"&scope=crmapi")
params = {"xmlData":self.xml}
data = urllib.urlencode(params)
request = urllib2.Request(url = url, data =data)
request.add_header("Content-Type",'application/xml')
response = urllib2.urlopen(request)
You cannot combine HTTP GET query parameters (ones in URL) and HTTP POST parameters.
This is limitation on the HTTP protocol level, not in Python or Zoho.
Most likely you are doing it wrong. Revisit Zoho documentation how it should be done.
Here is another old library doing Zoho + CRM, written in Python. You might want to check it for inspiration: https://github.com/miohtama/mfabrik.zoho
I am trying to send data from a javascript app running in GTK webkit to Python via a HTTP request with the data sent in POST.
I can capture the request using resource-request-starting and checking the uri of the request.
I know the request works because I can send data through the request headers and view it with
def on_resource_request_starting(view, frame, resource, request, response):
uri = urllib.unquote(request.props.uri)
if uri.startswith('http://appname.local/'):
print request.get_message().request_headers.get_one('foobar')
But when I use print request.get_message().request_body.data I don't get anything.
How do I view the POST data?
I haven't used this API, but I believe you need to call the binding's equivalent of soup_message_body_flatten() before reading the data field. See the documentation for SoupMessageBody in the C API.
So, at a guess:
print request.get_message().request_body.flatten().data
Hooking to SoupSession "request-queued" signal and getting
buffer(s) using soup_message_body_get_chunk(soupmsgbody, num);
seems to work (in webkitgtk1 today, Jun 2015).
webkit_get_default_session() returns the SoupSession in question.
I'm currently working on a automated way to interface with a database website that has RESTful webservices installed. I am having issues with figure out the proper formatting of how to properly send the requests listed in the following site using python.
https://neesws.neeshub.org:9443/nees.html
Particular example is this:
POST https://neesws.neeshub.org:9443/REST/Project/731/Experiment/1706/Organization
<Organization id="167"/>
The biggest problem is that I do not know where to put the XML formatted part of the above. I want to send the above as a python HTTPS request and so far I've been trying something of the following structure.
>>>import httplib
>>>conn = httplib.HTTPSConnection("neesws.neeshub.org:9443")
>>>conn.request("POST", "/REST/Project/731/Experiment/1706/Organization")
>>>conn.send('<Organization id="167"/>')
But this appears to be completely wrong. I've never actually done python when it comes to webservices interfaces so my primary question is how exactly am I supposed to use httplib to send the POST Request, particularly the XML formatted part of it? Any help is appreciated.
You need to set some request headers before sending data. For example, content-type to 'text/xml'. Checkout the few examples,
Post-XML-Python-1
Which has this code as example:
import sys, httplib
HOST = www.example.com
API_URL = /your/api/url
def do_request(xml_location):
"""HTTP XML Post requeste"""
request = open(xml_location,"r").read()
webservice = httplib.HTTP(HOST)
webservice.putrequest("POST", API_URL)
webservice.putheader("Host", HOST)
webservice.putheader("User-Agent","Python post")
webservice.putheader("Content-type", "text/xml; charset=\"UTF-8\"")
webservice.putheader("Content-length", "%d" % len(request))
webservice.endheaders()
webservice.send(request)
statuscode, statusmessage, header = webservice.getreply()
result = webservice.getfile().read()
print statuscode, statusmessage, header
print result
do_request("myfile.xml")
Post-XML-Python-2
You may get some idea.
