python - curl -u 和 python 请求之间有区别吗

Question

所以我想用 python.Requests 检索一个网页

https://ororo.tv/api/v2/episodes/9

这需要基本身份验证。如果我像这样 curl

 curl -u test@example.com:password https://ororo.tv/api/v2/episodes/9

然而，当我尝试在 python 中使用 Requests 做同样的事情时，我得到了我想要的响应。图书馆，像这样

>>> r = requests.get('https://ororo.tv/api/v2/episodes/9', auth=('test@example.com', 'password'))
>>> r
<Response [520]>

我总是收到 520 响应。有人能告诉我，我可能做错了什么吗？

是的，有细微的差别。发送的 header 略有不同，这些显然对这个 API 很重要。

如果您将查询的 URL 更改为使用 http://httpbin.org/get (在线 HTTP test service HTTPBin.org 的一个端点，你可以看到 curl 和 requests 发送的区别:

$ curl -u test@example.com:password http://httpbin.org/get
{
  "args": {},
  "headers": {
    "Accept": "*/*",
    "Authorization": "Basic dGVzdEBleGFtcGxlLmNvbTpwYXNzd29yZA==",
    "Host": "httpbin.org",
    "User-Agent": "curl/7.51.0"
  },
  "origin": "84.92.98.170",
  "url": "http://httpbin.org/get"
}
$ python -c "import requests; print(requests.get('http://httpbin.org/get', auth=('test@example.com', 'password')).text)"
{
  "args": {},
  "headers": {
    "Accept": "*/*",
    "Accept-Encoding": "gzip, deflate",
    "Authorization": "Basic dGVzdEBleGFtcGxlLmNvbTpwYXNzd29yZA==",
    "Host": "httpbin.org",
    "User-Agent": "python-requests/2.11.1"
  },
  "origin": "84.92.98.170",
  "url": "http://httpbin.org/get"
}

要突出差异:

requests发送一个额外的 header ，Accept-Encoding ，设置为 gzip, deflate

User-Agent header 不同；两者都反射(reflect)了当前的代理。

您必须查看这些 header 中的哪一个导致了 https://ororo.tv/api/v2 上的问题。地点。当我更正 URL 以使用 v2 时和 https ，如 curl命令， 和 设置 User-Agent header 然后我得到一个有效的响应:

>>> headers = {'User-Agent': 'curl/7.51.0'}
>>> r = requests.get('https://ororo.tv/api/v1/episodes/9',
                     auth=('test@example.com', 'password'), headers=headers)
>>> r
<Response [200]>
>>> from pprint import pprint
>>> pprint(r.json())
