請求模組是否會截斷標頭?

問題內容

我正在嘗試使用相當長(1017 個字元)的承載令牌向我的 API 發出 POST 請求以進行授權。

無論我嘗試什麼,當我啟動請求時,我都會收到一條錯誤訊息,指出位置 512 中的 \u2026 (水平省略號)無法使用「latin-1」編碼進行編碼。由於我找不到我指定的標頭的任何問題(或省略號),我唯一的解釋是請求模組在內部默默地截斷了我的令牌。難道是這樣嗎?可以禁用嗎?還有其他解決方法嗎?


正確答案


不,它不會截斷標頭。您可以透過執行列印所有收到的請求的 localhost http 伺服器來查看這一點。以下是使用 2000 個字元標記的範例。

# from https://gist.github.com/mdonkers/63e115cc0c79b4f6b8b3a6b797e485c7
from http.server import basehttprequesthandler, httpserver
import logging

class s(basehttprequesthandler):
    def _set_response(self):
        self.send_response(200)
        self.send_header('content-type', 'text/html')
        self.end_headers()

    def do_post(self):
        content_length = int(self.headers['content-length']) 
        post_data = self.rfile.read(content_length) 
        logging.info("post request,\npath: %s\nheaders:\n%s\n\nbody:\n%s\n",
                str(self.path), str(self.headers), post_data.decode('utf-8'))

        self._set_response()
        self.wfile.write("post request for {}".format(self.path).encode('utf-8'))

def run(server_class=httpserver, handler_class=s):
    logging.basicconfig(level=logging.info)
    server_address = ('', 8080)
    httpd = server_class(server_address, handler_class)
    try:
        httpd.serve_forever()
    except keyboardinterrupt:
        pass
    httpd.server_close()

if __name__ == '__main__':
    run()

在本機上運行它,然後使用請求來發布請求:

import requests
import random
import string

token = ''.join(random.choices(string.ascii_letters, k=2000))
requests.request('post', 'http://localhost:8080', headers={'token': token}, body='hello world')
登入後複製

產生以下輸出:

INFO:root:POST request,
Path: /
Headers:
Host: localhost:8080
User-Agent: python-requests/2.31.0
Accept-Encoding: gzip, deflate, br
Accept: */*
