I need to update my sensor data to thingspeak , so I was doing it with the python thingspeak library. Two days ago it was working fine but now it doesn't work, the connection times out , I also tried to update it with urllib2 ,that too doesnt' work.
My net connection is fine, I am able to open webpages on Pi and I can update the channel from my laptop using thingspeak library as well as urllib2.
could someone kindly help me.
my code with thingspeak library:
node = False
channel_id = ""
write = ""
if data['MAC'] in ':ab:35':
channel_id = "XXXXX"
write = "XXXXXXXXXXX"
node = True
if node:
channel = thingspeak.Channel(id=channel_id,write_key=write)
try :
response=channel.update({1:data['TEMP'],2:data['VOLT'],3:data['PRES'],4:data['HUM']})
print response
print 'Thingspeak updated!!!'
except :
print "connection failed"
when i try urllib2 :
f = urllib2.urlopen(url)
Traceback (most recent call last):

I am using the raspberry-pi to send data to thingspeak.
What I do is something like this:
import httplib
import urllib
#Preparing to send the information to the cloud
params=urllib.urlencode({'field1':liters,'key':key})
headers={"Content-typZZe": "application/x-www-form-urlencoded","Accept":"text/plain"}
conn=httplib.HTTPConnection("api.thingspeak.com:80")
#Sending the data to the thingspeak platform
try:
conn.request("POST", "/update", params, headers)
response=conn.getresponse()
print response.status, response.reason
data=response.read()
conn.close()
except:
print "connection failed"
And it works just fine.
The key is the string of your channel key.
Hope it helps.
If I use SSH and try to run the script, it works .
Add a new User-Agent, by creating Request objects & using them as arguments for urlopen:
import urllib2
request = urllib2.Request('http://www.example.com/')
request.add_header('User-agent', 'Mozilla/5.0 (Linux i686)')
response = urllib2.urlopen(request)

Not sure why this is happening. The same issue happens with or without running in virtualenv. It was running fine when I ran it (many times) without any virtualenv, then I created the virtualenv on my machine and ran it again, it's working fine. But on the next day, the error occurs when I try to run it.
Appreciate any help, many thanks!
Looks to me that the service that was listening for at port 4990 is not listening anymore. I suppose you know what service this is, so I recommend to check if it's running.
After you start the service that listen at port 4990, there are two ways to confirm you the port is really open and listening:
If you are using linux, you can check what ports are listening in your machine with the following command:
sudo lsof -i -P -n | grep LISTEN
You can try to connect to the port 4990 using telnet:
telnet 127.0.0.1 4990
If the telnet works, the output should be something like this:
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.
So im trying to use python to send a post to a url, i have basically copied everything from my network console in firefox yet i can't get it to work.
import requests
import json
url = 'https://www.example.com/example?handle'
cookie = {'UID':'b56f14d8-02b1-4ae8-ad5e-3485cf0abdbe'}
data ={'example':'example'}
headers = {'Accept':'*/*',
'Accept-Encoding':'gzip, deflate, br',
'Accept-Language':'en-US,en;q=0.5',
'Connection':'keep-alive',
'Content-Length':'78',
'Content-Type':'text/plain;charset=UTF-8',
'Cookie':'UID=b56f14d8-02b1-4ae8-ad5e-3485cf0abdbe',
'Host':'www.example.com',
'Referer':'https:/example.com/example',
'User-Agent':'Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:65.0) Gecko/20100101 Firefox/65.0'}
req = requests.post(url, cookies=cookie, params=json.dumps(data), headers=headers)
print(req)
I have replaced the actual data and url with example.
After running this, i get a big long error:

Does anyone know about what i could be doing wrong. Sorry if its a rookie mistake.
This error occurs when the web server rejects your connection. A web server can reject your connection for various reasons. Most likely, you did not properly mimic the HTTP request the web server was expecting.
You do not have to manually fill in all of the HTTP parameters such content length. The library automatically fills in these fields for you. If you plan to make subsequent HTTP requests using the same cookies, consider creating a session object, which stores and handles the cookies for you:
session = requests.Session()
session.post(url, data=payload)
Also, realize the difference between the data parameter and the params parameter. Since you are sending a POST request, chances are that the web server is expecting the data to be passed via the data parameter (which places the data in the request body rather than the query string in the URL). Another reason a web server may reject your connection is because you sent a HTTP request rather than a HTTPS request, so always ensure everything is correct on your end.
Below the code that i use to send post information and read the response,
import urllib2

I'm trying to translate a bash script that works with curl to send a code remotely to a mega Arduino, using an ESP01 as a programmer with the ESP-link firmware, the bash script that does that work, summarized in a few lines, is this:
#! /bin/bash
# first make a post to reset the arduino
curl -m 10 -s -w '%{http_code}' -XPOST
http://192.168.4.1/pgmmega/sync
sleep 0.5
# make a GET to Sync with it and wait for the sync
curl -s http://192.168.4.1/pgmmega/sync
sleep 0.1
#send the .hex file
curl -m 20 -s -g -d #/tmp/arduino_build_274266/SMI_6_0_1.ino.hex
http://192.168.4.1/pgmmega/upload
And my code in python3 is:
#! /bin/python3
import requests
import time
urlsync = 'http://192.168.4.1/pgmmega/sync'
urlupload = 'http://192.168.4.1/pgmmega/upload'
file = {'upload_file':
open('/home/wander/app_llamadores/SMI_6_0_1.ino.hex', 'rb')}
rsync = requests.post(urlsync, stream=True, timeout = 5)
time.sleep(0.4)
print(rsync1.status_code) #204
rsync1 = requests.get(urlsync)
print(rsync1.status_code) #200
rupload = requests.post(urlupload, files=file, timeout=20)
print(rupload.status_code)
I tried with that code, and although the synchronization part seems to work fine, when I send the .hex file, I get this ..

Your curl and requests commands are not equivalent.
With curl you are HTTP POSTing data directly in the request body. With requests you are (implicitly) creating MultiPart Encoded form data, with upload_file field set to the contents of the SMI_6_0_1.ino.hex file.
Simple way to see what is happening under the hood is to prepare request, is to prepare and inspect request without sending:
from requests import Request
url = "http://192.168.4.1/pgmmega/sync"
filename = "SMI_6_0_1.ino.hex"
req = Request("POST", url, files={"upload_file": open(filename, "rb")}).prepare()
print(vars(req)["body"])
# b'--052baa09bbc2f6ab52a2c9f8f2b99b3a\r\nContent-Disposition: form-data; name="upload_file"; filename="SMI_6_0_1.ino.hex"\r\n\r\n\r\n--052baa09bbc2f6ab52a2c9f8f2b99b3a--\r\n'
print(vars(req)["headers"]["Content-Type"])
# multipart/form-data; boundary=052baa09bbc2f6ab52a2c9f8f2b99b3a
and
req = Request("POST", url, data=open(filename, "rb")).prepare()
print(vars(req)["body"])
# <_io.BufferedReader name='SMI_6_0_1.ino.hex'>
print(vars(req)["headers"]["Content-Type"])
# KeyError: 'content-type'
So most probably requests are sending a file in format that cannot be read by target server. In this case, switch to requests.post(url, data=...) should fix the problem.
This is not that uncommon problem. There is a web page, where you can convert curl to requests on your own - https://curl.trillworks.com/
I am using Ubuntu 12 with VitualBox on top of a Windows XP PC. I am using a proxy to access the internet.
I can browse those websites with Firefox, and for script below:

Please help me out. Thanks.
Try creating a https handler and see if that fixes the problem.
Change this line:
proxy = urllib2.ProxyHandler({'http': 'http://my-proxy-server:80'})
to
proxy = urllib2.ProxyHandler({'https': 'http://my-proxy-server:80'})
and see if that works, since the Twitter API you are trying to access is over HTTPS.
from poster.encode import multipart_encode
from poster.streaminghttp import register_openers
def picscrazy(str,int):
register_openers()
datagen, headers = multipart_encode({"imagefile[]": open(str, "rb")})
request = urllib2.Request("http://www.picscrazy.com/process.php", datagen, headers)
Str is the filename and the int is just another flag.
The code is to upload a file to a image hosting website .I am using poster Poster for the post requests. The program stops after the request statement and gives an error .I cant understand the error whether its a problem in my network or in the program.
Below is the traceback of the error:

If you can't display the header coming back from the server, then, your server has simply cut you off.
It may be your request is bad -- but that's unlikely.
It may be that you've exceeded bandwidth restrictions.
It may be that your requests appear to be a DDOS attack because they're happening too frequently.
