python-requests

问题 I am trying to pull the json from this location - https://www.nseindia.com/api/option-chain-indices?symbol=BANKNIFTY This opens fine in my browser, but using requests in python throws a 401 permission error. I have tried adding headers with different arguments, but to no avail. Interestingly, the json on this page does not open in the browser as well until https://www.nseindia.com is opened separately. I believe it requires some kind of authentication, but surprised it works in the browser

问题 Use Case: I am trying to connect to a streaming API, ingest those events, filter them and save relevant ones. Issue: My code works well until about 1100th response. After this point the code doesn't crash but it seems to stop pulling more data from the stream.

Code import requests def stream(): s = requests.Session() r = s.get(url, headers=headers, stream=True) for

问题 I am trying to make a request in Python using TLS 1.3 as it is what the site accepts. I use following code: import requests from requests.adapters import HTTPAdapter from requests.packages.urllib3.poolmanager import PoolManager from requests.packages.urllib3.util import ssl_ CIPHERS = ( 'AES128-GCM-SHA256:ECDHE-RSA-AES128-SHA256:AES256-SHA' ) class TlsAdapter(HTTPAdapter): def __init__(self, ssl_options=0, **kwargs): self.ssl_options = ssl_options super(TlsAdapter, self).__init__(**kwargs)

问题 i have problem with streaming download large file (about 1.5 GB) in python-requests v. 2.0.1 with open("saved.rar",'wb') as file: r = session.get(url,stream=True,timeout=3600) for chunk in r.iter_content(chunk_size=1024): if chunk: file.write(chunk) file.flush() I tested it few times on my vps and sometimes it downloaded 200mb, 500mb or 800mb and saved it without any error. It doesnt reached the timeout, just stopped like finish downloading. Host where im downloading this file is stable

问题 Below is the complete code simplified for the question. ids_to_check returns a list of ids. For my testing, I used a list of 13 random strings. #!/usr/bin/env python3 import time from multiprocessing.dummy import Pool as ThreadPool, current_process as threadpool_process import requests def ids_to_check(): some_calls() return(id_list) def execute_task(id): url = f"https://myserver.com/todos/{ id }" json_op = s.get(url,verify=False).json() value = json_op['id'] print(str(value) + '-' + str

问题 Where is the HTTP/1.1 mandatory Host header field in HTTP request messages generated by the requests Python library? import requests response = requests.get("https://www.google.com/") print(response.request.headers) Outputs this: {'User-Agent': 'python-requests/2.22.0', 'Accept-Encoding': 'gzip, deflate', 'Accept': '*/*', 'Connection': 'keep-alive'} 回答1: The HOST header is not being added to the request by requests by default. If it is not explicitly added then the decision is delegated to
