使用 Python 请求对 magiccardmarket 进行 OAuth 身份验证

我想以编程方式获取 http://www.cardmarket.com/上特定用户的库存>，但似乎无法在以下 Python 代码段中使用 OAuth 身份验证.

I want to programmatically fetch the stock of specific users on http://www.cardmarket.com/, but can't seem to get OAuth authentication to work in the following Python snippet.

简单地使用 requests_oauthlib 库中的可用方法没有给出任何积极的结果，我还尝试自己构建 OAuth 标头并将其传递到请求调用中，但都无济于事.我有点不知所措，因为我已经尝试了几个小时没有结果，以至于我已经失去了对本应是一个简单的爱好项目的最大乐趣.尽管如此，我相信这是一个很简单的问题，有望很快得到解决.

Simply using available methods from the requests_oauthlib library have not given any positive results and I've also tried constructing the OAuth header myself and passing that along in the requests-call, all to no avail. I'm a bit at the end of my wits, because I've tried for hours without results, to the point where I've lost most enjoyment for what should have been a simple hobby project. Nonetheless I'm confident that it's a simple problem that can hopefully be resolved quickly.

这是应该可以但不可以工作的简单代码:

Here's the simple code that should, but doesn't, work:

import requests
from requests_oauthlib import OAuth1

user = ..

app_token  = ..
app_secret = ..
access_token = ..
access_token_secret = ..

request_url = "https://api.cardmarket.com/ws/v2.0/users/" + user + "/articles?start=0&maxResults=100"

auth = OAuth1(app_token, app_secret, resource_owner_key=access_token, resource_owner_secret=access_token_secret)
response = requests.get(request_url, auth=auth)    

print(response.request.headers)
print(response)
print(response.content)

我也尝试了多种变体，如上所述，我也尝试过自己构建标题，但没有结果.

I've also tried a mixture of variations to it and as stated, have also tried to construct the header myself, but with no results.

我没有发现提供的代码有任何问题，但在执行给定查询时仍然收到未经授权的错误.

I don't see anything wrong with the provided code as-is, but still get an error for being unauthorized when performing the given query.

response.request.headers 打印语句返回以下内容:

The response.request.headers print statement returns the following:

{'Authorization': b'OAuth oauth_nonce="..", oauth_timestamp="..", oauth_version="1.0", oauth_signature_method="HMAC-SHA1", oauth_consumer_key="..", oauth_token="..", oauth_signature=".."', 'Accept-Encoding': b'gzip, deflate', 'User-Agent': b'python-requests/2.18.4', 'Accept': b'*/*', 'Connection': b'keep-alive'}

这似乎包括所有相关数据(虽然可能太多了?诸如 Accept-Encoding、User-Agent 和 Connection 之类的东西会自动添加，但可能不是预期的，但我不确定.)

Which seems the include all relevant data (though maybe too much? Things like Accept-Encoding, User-Agent and Connection are automatically added, but may not be expected, but I'm not sure.)
