Chr*_* B. 236 python debugging https python-requests
就我而言,我正在使用该requests库通过HTTPS调用PayPal的API.不幸的是,我从PayPal收到错误,并且PayPal支持无法弄清楚错误是什么或导致错误.他们要我"请提供整个请求,包括标题".
我怎样才能做到这一点?

一种简单的方法:启用最近版本的请求(1.x和更高版本)的日志记录.
请求使用http.client和logging模块配置成控制日志记录级别,如所描述这里.
摘自链接文档的代码:
import requests
import logging
# These two lines enable debugging at httplib level (requests->urllib3->http.client)
# You will see the REQUEST, including HEADERS and DATA, and RESPONSE with HEADERS but without DATA.
# The only thing missing will be the response.body which is not logged.
try:
import http.client as http_client
except ImportError:
# Python 2
import httplib as http_client
http_client.HTTPConnection.debuglevel = 1
# You must initialize logging, otherwise you'll not see debug output.
logging.basicConfig()
logging.getLogger().setLevel(logging.DEBUG)
requests_log = logging.getLogger("requests.packages.urllib3")
requests_log.setLevel(logging.DEBUG)
requests_log.propagate = True
requests.get('https://httpbin.org/headers')

r是一个回应.它有一个请求属性,其中包含您需要的信息.
r.request.allow_redirects r.request.headers r.request.register_hook
r.request.auth r.request.hooks r.request.response
r.request.cert r.request.method r.request.send
r.request.config r.request.params r.request.sent
r.request.cookies r.request.path_url r.request.session
r.request.data r.request.prefetch r.request.timeout
r.request.deregister_hook r.request.proxies r.request.url

r.request.headers 给出标题:

'Accept-Encoding': 'identity, deflate, compress, gzip',
'Authorization': u'Basic dXNlcjpwYXNz',

然后r.request.data将身体作为映射.urllib.urlencode如果他们愿意,您可以转换它:
import urllib
b = r.request.data
encoded_body = urllib.urlencode(b)

调试 HTTP 本地请求的一种更简单的方法是使用 netcat。如果你跑
nc -l 1234
Run Code Online (Sandbox Code Playgroud)
您将开始侦听端口上1234的 HTTP 连接。您可以通过 访问它http://localhost:1234/foo/foo/...。
在终端上,您将看到发送到端点的任何原始数据。例如:
POST /foo/foo HTTP/1.1
Accept: application/json
Connection: keep-alive
Host: example.com
Accept-Language: en-en
Authorization: Bearer ay...

没有日志系统可以完全工作,(无论如何,从请求 2.26 开始,非常旧的版本可能有另一种行为)
\n好的解决方案是使用“钩子”并在发生时打印详细信息。
\n这在这里得到了很好的解释:https ://findwork.dev/blog/advanced-usage-python-requests-timeouts-retries-hooks/
\n在“打印所有内容”下,
\n但万一链接失效了,这里是重要的部分
\nimport requests\nfrom requests_toolbelt.utils import dump\n\ndef logging_hook(response, *args, **kwargs):\n data = dump.dump_all(response)\n print(data.decode(\'utf-8\'))\n\nhttp = requests.Session()\nhttp.hooks["response"] = [logging_hook]\n\nhttp.get("https://api.openaq.org/v1/cities", params={"country": "BA"})\nRun Code Online (Sandbox Code Playgroud)\n这次的结果将是发送的查询和接收的响应的完整跟踪。
\n我已经通过 POST 和大量标头成功尝试过:它有效。\n不要忘记 pip install requests_toolbelt。

您可以使用HTTP Toolkit来完成此操作。
如果您需要快速执行此操作而无需更改代码,它尤其有用:您可以从 HTTP Toolkit 打开终端,照常从那里运行任何 Python 代码,您将能够看到每个 HTTP/HTTPS 的完整内容立即请求。
有一个免费版本可以做你需要的一切,而且它是 100% 开源的。
我是 HTTP Toolkit 的创建者;实际上,我自己构建了它来为我解决完全相同的问题!我也试图调试支付集成,但他们的 SDK 不起作用,我不知道为什么,我需要知道实际发生了什么才能正确修复它。这非常令人沮丧,但能够看到原始流量确实有帮助。
之前的答案似乎被否决了,因为它以“没有什么完全有效”开始,然后提供了这个完美的解决方案:
requests_toolbelt实用程序集合pip install requests-toolbelt。import requests
from requests_toolbelt.utils import dump
response = requests.get("https://v2.jokeapi.dev/joke/Any?safe-mode")
print(dump.dump_all(response).decode("utf-8"))

如果您使用的是Python 2.x,请尝试安装urllib2开启工具.这应该打印出你的标题,虽然你可能必须将它与你用来点击HTTPS的其他开启者结合起来.
import urllib2
urllib2.install_opener(urllib2.build_opener(urllib2.HTTPHandler(debuglevel=1)))
urllib2.urlopen(url)
