我正在尝试使用Sendgrid发送密码重置电子邮件。

以下是错误的堆栈跟踪:

Traceback (most recent call last):
  File "C:\Program Files\Google\google_appengine\lib\webapp2-
2.5.2\webapp2.py", line 1535, in __call__

    rv = self.router.dispatch(request, response)

line 227, in http_request
    return Response(self._make_request(opener, request))
  File "C:\Users\C\PycharmProjects\alpha\python_http_client\client.py", 
line 161, in _make_request
    raise exc
UnauthorizedError

我已将sendgrid和python-http-client导入到我的项目中。 (为什么我必须单独导入它?)

以下是我从Sendgrid演示中获取的测试代码:

class PasswordResetHandler(BaseHandler):
"""
handler to reset the users password.
also to verify if the user email is in the database
"""
def post(self):
    email = self.request.get("email_for_reset")

    sg = sendgrid.SendGridAPIClient(apikey=os.environ.get(SENDGRID_API_KEY))
    from_email = Email("email@example.com")
    to_email = Email(email)
    subject = "Sending with SendGrid is Fun"
    content = Content("text/plain", "and easy to do anywhere, even with Python")
    mail = Mail(from_email, subject, to_email, content)
    response = sg.client.mail.send.post(request_body=mail.get())
    self.redirect('/u/password-reset-confirmation')

任何人都可以帮忙解决这里发生的事情吗?

感谢。

我使用的语法不同,使用SendGridClient

sg = sendgrid.SendGridClient(SENDGRID_API_KEY)

message = sendgrid.Mail(
    to =            to, 
    subject =       subject, 
    html =          html, 
    text =          body, 
    from_email =    sender
)

status, msg = sg.send(message)

检查您的API密钥是否存在拼写错误,并确保使用os.environ.get()正确加载。

您收到HTTP错误401.正如您在第161行(及其前面的行)上看到in the client.py code包含_make_request的那样,您将收到第159行中正在处理的HTTPError :

exc = handle_error(err)

handle_error()已实现in exceptions.py,并显示UnauthorizedError来自HTTPError 401.最可能的原因是错误的api密钥。检查你的api密钥是否有拼写错误。通过在我的代码中插入一个错误的api密钥,我能够得到相同的HTTP错误。除此之外,我有这个功能使用您在问题中显示的相同代码。
