Sending multiple sms in quick succession using Twilio

I am trying to send sms using twilio and django 1.8.2. I am facing a problem when there are multiple calls to send sms within the same function.
This is the code snippet to send an sms to any particular phone number:
def send_twilio_message(to_number, body):
client = twilio.rest.TwilioRestClient(
settings.TWILIO_ACCOUNT_SID, settings.TWILIO_AUTH_TOKEN)
return client.messages.create(
body=body,
to=to_number,
from_=settings.TWILIO_PHONE_NUMBER
)
When I make two requests to this function like this:
def some_function():
send_twilio_message(number1, "text 1")
send_twilio_message(number2, "text 2")
I am getting this error:
Traceback:

But, when I do this:
import time
def some_function():
send_twilio_message(number1, "text 1")
time.sleep(60)
send_twilio_message(number2, "text 2")
it is working fine. The problem with this approach is that the user might close the browser if the page keeps loading for 60 seconds (I've tried for less than 60 seconds, I get the same error).
I've tried disabling SSL verification in my Twilio account, but that didn't work.
I've looked into other answers, and I've gone through Twilio's documentation. I haven't been able to figure out a good solution. Any help will be appreciated.
Edit:
I was trying all this on my localserver. When I tried the code:
def some_function():
send_twilio_message(number1, "text 1")
send_twilio_message(number2, "text 2")
on a hosted server, it worked fine. So, I think the problem might be due to my institute's network. The problem is resolved for me, but I still haven't been able to figure out why I was facing the issue. If anyone has any idea why this might be happening, please post your answer.

Timeout Error when using proxy with httplib2 in Python

i have a simple code that uses proxy to submit a "GET" request to google .
import httplib2
http = httplib2.Http(proxy_info = httplib2.ProxyInfo(proxy_type=3,proxy_host=myProxy, proxy_port=myPort))
resp, content = http.request("http://google.com", "GET")
print(resp)
print(content)
For some reason i get a Timeout error :
resp, content = http.request("http://google.com", "GET")

TimeoutError: [WinError 10060] A connection attempt failed because the connecte
party did not properly respond after a period of time, or established connecti
n failed because connected host has failed to respond
I'm using a valid proxy, but this module doesn't works, Does anybody knows why this happened?

Win Error 10060 means that no connection can be made and that either the host or the connection(proxy) is at fault. Since google is virtually never down we can narrow down the problem to the proxy configuration.
Since you seemingly configured the proxy correctly (assuming you pass the right types and arugments ) you might want to check what SOCKS protocol the server additionally supports.
Either your're not passing valid values as a proxy configuration or it is the server's fault.
You could also try to diagnose with wireshark to see if any packets even make it to the server.

Automated Test Run - Python HTTPResponseNotReady()

I am trying to create an automated test using python for testing a youtube API request and response and all of those happening in random quick timely manner.
What I have been getting is an unstable HTTP response from the server.
I am not using the same object for every connection as I made it in separate methods, but when testing it, I test it all in same method (i.e. call create,edit, and delete consecutively)
Here is the Error that I got.
File "/var/lib/jenkins/shiningpanda/jobs/2a430f4f/virtualenvs/d41d8cd9/local/lib/python2.7/site-packages/oauth2client/client.py", line 490, in new_request

response = conn.getresponse()
File "/usr/lib/python2.7/httplib.py", line 1018, in getresponse
raise ResponseNotReady()
ResponseNotReady
I was thinking that I should have a time.delay() between each HTTP request?
What do you guys think and suggest me to do on this case, since I am still learning on this matter?
Thank you for all the sugesstion and help ;)
Basic Idea of the Code I am using :
yt_service = gdata.youtube.service.YouTubeService()
yt_service.email = 'exampple#gmail.com'
yt_service.password = 'password'
def GetAndPrintUserUploads(username):
yt_service = gdata.youtube.service.YouTubeService()
uri = 'http://gdata.youtube.com/feeds/api/users/%s/uploads' % username
PrintVideoFeed(yt_service.GetYouTubeVideoFeed(uri))
and for testing it I authenticate the user and print user upload a few time after that consecutively

Python BadStatusLine error on certain DELETE requests

I am trying to use the python-rest-client ( http://code.google.com/p/python-rest-client/wiki/Using_Connection ) to perform testing of some RESTful webservices. Since I'm just learning, I've been pointing my tests at the sample services provided at http://www.predic8.com/rest-demo.htm.
I have no problems with creating entries, updating entries, or retrieving entries (POST and GET requests). When I try make a DELETE request, it fails. I can use the Firefox REST Client to perform DELETE requests and they work. I can also make DELETE requests on other services, but I've been driving myself crazy trying to figure out why it doesn't work in this case. I'm using Python 3 with updated Httplib2, but I also tried Python 2.5 so that I could use the python-rest-client with the included version of Httplib2. I see the same problem in either case.
The code is simple, matching the documented use:
from restful_lib import Connection
self.base_url = "http://www.thomas-bayer.com"
self.conn = Connection(self.base_url)
response = self.conn.request_delete('/sqlrest/CUSTOMER/85')
I've looked at the resulting HTTP requests from the browser tool and from my code and I can't see why one works and the other doesn't. This is the trace I receive:
Traceback (most recent call last):
File "/home/fmk/python/rest-client/src/TestExampleService.py", line 68, in test_CRUD

version, status, reason = self._read_status()
File "/usr/lib/python3.2/http/client.py", line 316, in _read_status
raise BadStatusLine(line)
http.client.BadStatusLine: ''
What's breaking? What do I do about it? Actually, I'd settle for advice on debugging it. I've changed the domain in my script and pointed it at my own machine so I could view the request. I've viewed/modified the Firefox requests in BurpProxy to make them match my script requests. The modified Burp requests still work and the Python requests still don't.

Apparently the issue is that the server expects there to be some message body for DELETE requests. That's an unusual expectation for a DELETE, but by specifying Content-Length:0 in the headers, I'm able to successfully perform DELETEs.
Somewhere along the way (in python-rest-client or httplib2), the Content-Length header is wiped out if I try to do:
from restful_lib import Connection
self.base_url = "http://www.thomas-bayer.com"
self.conn = Connection(self.base_url)
response = self.conn.request_delete('/sqlrest/CUSTOMER/85', headers={'Content-Length':'0'})
Just to prove the concept, I went to the point in the stack trace where the request was happening:
File "/home/fmk/python/rest-client/src/httplib2/__init__.py", line 897, in _conn_request
response = conn.getresponse()
I printed the headers parameter there to confirm that the content length wasn't there, then I added:
if(method == 'DELETE'):
headers['Content-Length'] = '0'
before the request.
I think the real answer is that the service is wonky, but at least I got to know httplib2 a little better. I've seen some other confused people looking for help with REST and Python, so hopefully I'm not the only one who got something out of this.

The following script correctly produces 404 response from the server:
#!/usr/bin/env python3
import http.client
h = http.client.HTTPConnection('www.thomas-bayer.com', timeout=10)
h.request('DELETE', '/sqlrest/CUSTOMER/85', headers={'Content-Length': 0})
response = h.getresponse()
print(response.status, response.version)
print(response.info())
print(response.read()[:77])
python -V => 3.2
curl -X DELETE http://www.thomas-bayer.com/sqlrest/CUSTOMER/85
curl: (52) Empty reply from server
Status-Line is not optional; HTTP server must return it. Or at least send 411 Length Required response.
curl -H 'Content-length: 0' -X DELETE \
http://www.thomas-bayer.com/sqlrest/CUSTOMER/85
Returns correctly 404.

Python YQL package Error

Hi I am new to Python...
I am trying to use YQL using Python.
I installed httplib2-0.7.0, oauth2 and then installed yql package
For this sample code :
import yql
y = yql.Public()
query = 'select * from flickr.photos.search where text="panda" limit 3';
result = y.execute(query)
print result
I got the following error message.
Please help!!

When I tried to use the *twitter python wrapper, I ended up getting the same SSL error.*
Please tell me what to do

I can see two likely issues:
SSL Certificate
I'm not familiar with Python or that library you're using, but the error sounds like it can't verify the SSL certificate. (Possibly because there is no suitable local SSL certificate bundle for authentication.) You may be able to configure it to skip the SSL certificate verification.
YQL Flickr Query
The YQL query is not correct and gives an error in the YQL console:
select * from flickr.photos.search where text="panda" limit 3
Actually, given the age of this question, it may have worked in June 2011. Now the Flickr tables require an API key as well, so the working query would look like:
select * from flickr.photos.search where text="panda" and api_key="insert-your-key-here" limit 3
