我尝试使用 Python 客户端连接到 Upwork API。

我的项目类型是“桌面”,关键是“活动”。

但是,身份验证 url 返回 403,并且在浏览器中显示“未经授权”消息。

在此处输入图像描述

这是代码,它只是尝试重新创建API 文档中的步骤。

import upwork
import requests

public_key = ''
secret_key = ''

client = upwork.Client(public_key, secret_key)
authorize_url = client.auth.get_authorize_url()

requests.get(authorize_url)

我还阅读了另一个问题,其中维护者(?)建议不要使用 Python 3。但是,由于我想使用pandas从 API 获取的数据,所以我需要依赖它。

同一问题的 OP 提到用requests_oauthlib包解决问题。下面是我尝试创建连接,但它也失败了。

from requests_oauthlib import OAuth1Session

oauth = OAuth1Session(public_key, secret_key)
fetch_response = oauth.fetch_request_token(authorize_url)

这是使用requests_oauthlib. 它提到他们认为我正在“使用自动化工具浏览网站”。

我应该如何解决这个问题的任何线索?

“未经授权”消息的原因是 URL 中的请求令牌无效 - 屏幕截图中 URL 中的“无”。

如果您使用包装器或类似的东西,请确保您创建一个有效的授权 URL 并使用令牌而不是空/未定义的值
