How to fix error in python requests?
I am using an API, which receives a pdf file and does some analysis, but I am receiving Response 500 always Have initially tested using Postman and the request goes through, receiving response 200 with the corresponding JSON information. The SSL security should be turned off. However, when I try to do request via Python, I always get Response 500 Python code written by me:
import requests url = "https://>/api/v1/documents" fin = open('/home/train/aab2wieuqcnvn3g6syadumik4bsg5.0062.pdf', 'rb') files = r = requests.post(url, files=files, verify=False) print (r) #r.text is empty import requests url = "https://>/api/v1/documents" payload = "------WebKitFormBoundary7MA4YWxkTrZu0gW\r\nContent-Disposition: form-data; name=\"file\"; filename=\"aab2wieuqcnvn3g6syadumik4bsg5.0062.pdf\"\r\nContent-Type: application/pdf\r\n\r\n\r\n------WebKitFormBoundary7MA4YWxkTrZu0gW--" headers = < 'content-type': "multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW", 'Content-Type': "application/x-www-form-urlencoded", 'cache-control': "no-cache", 'Postman-Token': "65f888e2-c1e6-4108-ad76-f698aaf2b542" >response = requests.request("POST", url, data=payload, headers=headers) print(response.text) < "id": "5e69058e2690d5b0e519cf4006dfdbfeeb5261b935094a2173b2e79a58e80ab5", "name": "aab2wieuqcnvn3g6syadumik4bsg5.0062.pdf", "fileIds": < "original": "5e69058e2690d5b0e519cf4006dfdbfeeb5261b935094a2173b2e79a58e80ab5.pdf" >, "creationDate": "2019-06-20T09:41:59.5930472+00:00" > UPDATE: Tried the GET request — works fine, as I receive the JSON response from it. I guess the problem is in posting pdf file. Is there any other options on how to post a file to an API? Postman Response RAW:

Рыжий Лис, Пальцем в небо, но всё же, Flask позволяет возвращать None ?
1. None поправил
2. timeout=0.001 — без этого параметра ошибка такая же

python requests login post get response code 500
when i run the code ,i get the response 500,but when i copy this link with params in the browser,it works and i could login. i cannot find the reason .i need the help,thanks!
There are many reasons why this could fail. For example, the login page may require some cookies to be set before making the login attempt. Or there might be some other request header that you are missing.
Response code 500 means a server side error. Do you get back any information on the error page send from the server? Do you have access to the server and can check with the log files of that server?

header_content = js_data = json.dumps() response = requests.post(link, data=js_data, headers=header_content, verify=False) if response.status_code == 200: print(response.content) You need to specify content in the header, in your case it is json. Also, as you perform a request through https, certificate verification could cause a problem, so turn the verification off by «verify=False». Also error in json format could be a reason of 500, so to be sure that you are passing appropriate json object, I recommend to use json.dumps(). Hope it helps. Regards!
when you get this error, first check to see if your webpage can be loaded in a browser or not .
it may shows some errors about permission. In this case, change the permission of your codeigniter folder with this command:
$ sudo chmod 755 -R /var/www/html/Codeigniter_folder_name Status code 500 not treated as exception
Making a request to the server, as in code below, I’ve got status code 500, which was not caught as an exception. The output was «500», but I need for all 500 codes to result in sys.exit(). Does requests.exceptions.RequestException not treat 500 as an exception or is it something else? The requests module docs http://docs.python-requests.org/en/latest/user/quickstart/#errors-and-exceptions are not very clear on what falls under this class. How do I make sure that all 500 codes result in sys.exit()?
import requests import json import sys url = http://www.XXXXXXXX.com headers = try: r = requests.post(url, headers=headers) status = r.status_code response = json.dumps(r.json(), sort_keys=True, separators=(',', ': ')) print status except requests.exceptions.RequestException as e: print "- ERROR - Web service exception, msg = <>".format(e) if r.status_code < 500: print r.status_code else: sys.exit(-1) 3 Answers 3
A status code 500 is not an exception. There was a server error when processing the request and the server returned a 500; more of a problem with the server than the request.
You can therefore do away with the try-except :
r = requests.post(url, headers=headers) status = r.status_code response = json.dumps(r.json(), sort_keys=True, separators=(',', ': ')) if str(status).startswith('5'): . Except in this case if it's a 501 or any other code, you'd have to code in every number above 500. Only useful if you know what response code the server will return, guaranteed
