HTTP 错误：HTTP 错误 400：错误请求（必须使用 urllib2 发出 HTTP 请求）

Question

我遇到了一个错误，在这里找到的所有类似答案都没有帮助我。

我得到一个

HTTPError：HTTP 错误 400：错误请求

当我尝试执行 Delete.py 文件的下一行代码时

def DeleteFBUser(idSocial):
    url = 'https://graph.facebook.com/{}/permissions&access_token={}'
    url = url.format(idSocial, FBToken)
    req = urllib2.Request(url)
    req.get_method = lambda: 'DELETE'
    response = urllib2.urlopen(req)

这就是完整的 Traceback

有什么想法吗？

Answer 1

你试过了吗：graph.facebook.com/me?access_token=TOKEN&fields=id,name,email

而不是：graph.facebook.com/{}/permissions&access_token={}

因为这是对 facebook api 的正确调用。
