So this seems like it would be a simple thing to do but I can't seem to get it to work. I want to send a post request to a local flask server running on my computer. So I use the following line of code to do it
r = requests.post(end_url + '/upload/flash', cookies=cookie, params='title=asdfg&description=asdfg&front1=f&back1=b&number=1&edu_level=&school=&course=&grade=&unit=&chapter=§ion=&tag=')
The problem is not with the params I'm passing into the function as they are formatted correctly. The problem is that the flask server is trying to access the "title" arg from the request but can't find it. All of the examples I have seen format the params in a dictionary (ex.
{"title": "asdfg"}
I would imagine that it is possible to send a request the way I am trying but am not sure what I have done wrong.
The problem was actually not with the params. I was mixing up "params" and "data". I also needed to include the headers
headers={"Content-Type": "application/x-www-form-urlencoded"}
Thanks to everyone who help me troubleshoot my code.

How can I know if a website is using apache, nginx or other and get this information in python? Thanks in advance
This information if available is given in the header of the response to a HTTP Request. With Python you can perform HTTP requests using the module requests.
Make a simple GET request to the interested site and then print the headers parameter of the returned object.
import requests
r = requests.get(YOUR_SITE)
print(r.headers)
The output is made of a dictionary of keys and value, you have to look for the Server parameter
server = r.headers['Server']
You must be aware that not all websites return this information for several reasons, so you could not find this key in the response header.
I'm using Python requests 2.19.1 .
But I'm facing an intermittent issue where I get no response at all when I post to a specific url.
I'm trying to check if the LDAP is giving me the expected output for invalid credentials.
Here's the format:
requests.post('https://oxhp-member.uhc.com/Member/MemberPortal/j_acegi_security_check',
credentials_payload)
that I'm posting
Almost everytime, it works fine. But sometimes, it doesn't give any response for that. Even network issues gives us some response. Right? Why am I not getting any response for the above call.
Is there any existing bug in requests?
Somebody please point me in correct direction.
requests is not responsible for "giving back response". The server you are using requests to post to is.
To see the response you have to keep it in a variable and handle it somehow.
resp = requests.post('https://oxhp-member.uhc.com/Member/MemberPortal/j_acegi_security_check',
credentials_payload)
print(resp.status_code)
print(resp.content)
Whatever resp contains is the responsibility of the server.
i am new to using the TOMTOM API but i got it working with the example in the browser without a problem, call:
https://api.tomtom.com/routing/1/calculateReachableRange/50.97452,5.86605/json/?key=[MYKEY]&timeBudgetInSec=3600
in the browser i get my json response with my polygon point. But in python i just get the error stating:
"Invalid request: should contain one of the following elements 'avoidVignette' or 'allowVignette'"
Does anybody have any idea why it works in the browser but gives an error when i use it in python code?
mycode:
request_post = requests.post('https://api.tomtom.com/routing/1/calculateReachableRange/50.97452,5.86605/json/?key=[MYKEY]&timeBudgetInSec=3600')
thanks in advance
I figured it out with the help of the comment of #ForceBru.
I used postman to figure out what the problem was and it seems that if you do not use the link directly in the browser but use it as a real post request you are needed to give it a xml or json body where you need to specifiy:
{"avoidVignette": []}
if you are using json.
If you put this in your post request as body it should work like a charm.
Working code:
requests.post('https://api.tomtom.com/routing/1/calculateReachableRange/50.97452,5.86605/json/?key=[MYKEY]&timeBudgetInSec=3600', json={"avoidVignette": []})
Hope this helps some people forward if they get the same error.
If You are not providing any POST parameters than You can use GET method.

I am a beginner so I apologize if my question is very obvious or not worded correctly.
I need to send a request to a URL so data can then be sent back in XLM format. The URL will have a user specific login and password, so I need to incorporate that as well. Also there is a port (port 80) that I need to include in the request. Is requests.get the way to go? I'm not exactly sure where to start. After receiving the XLM data, I need to process it (store it) on my machine - if anyone also wants to take a stab at that (I am also struggling to understand exactly how XLM data is sent over, is it an entire file?). Thanks in advance for the help.
Here is a python documentation on how to fetch internet resources using the urllib package.
It talks about getting the data, storing it in a file, sending data and some basic authentication.
https://docs.python.org/3/howto/urllib2.html
Getting the URL would look something like this import
Import urllib.request
urllib.request.urlopen("http://yoururlhere.co.uk").read()
Note that this is for strings and Python 3 only.
Python 2 version can be found here
What is the quickest way to HTTP GET in Python?
If you want to parse the data you may want to use this
https://docs.python.org/2/library/xml.etree.elementtree.html
I hope this helps! I am not too sure on how you would approach the username and password stuff but these links can hopefully provide you with information on how to do some of the other stuff!
Import the requests library and then call the post method as follows:
import requests
data = {
"email" : "netsparkertest#test.com",
"password" : "abcd12333",
}
r = requests.post('www.facebook.com', data=data)
print r.text
print r.status_code
print r.content
print r.headers
I'm trying to build a very simple REST API in Django 1.8 with Django REST Framework in Visual Studio, in which I want to have a single service method to process a JSON, but I can't seem to make a POST:
I'm trying to send this simple JSON through Postman, just as a test:
{
"foo":"bar"
}
with the header:
Content-Type: application/json
Here's my method:
#csrf_exempt
#api_view(['POST'])
def test(request):
data = request.data
return HttpResponse(status=200)
But my problem is that request.data is empty. And if instead I try to access request.body, I get
You cannot access body after reading from request's data stream.
Any ideas what could be the issue here?
Figured this out somewhat, it seems to be an issue with Visual Studio while in debug mode. If I try to access the request while debugging before calling any Python function on it (such as a simple print, or passing in to a function to parse it), it shows up as an empty QueryDict, otherwise it shows up fine.
Just a guess: maybe the issue is in Postman?
Try to send POST-request without headers, but with raw JSON (not form-data):
This may help Where's my JSON data in my incoming Django request?
Outside of this, make sure the content-type and accept-type are set properly. What is the raw response in Postman? Is the security setup properly?
I have the same problem when using POSTMAN.

Quoted Answer:
Request payload is not converted into JSON format.
I am passing my data in Body as x-www-form-urlencoded
You can fix it by using Content-Type as application/x-www-form-urlencoded in request header.
