Google oauth登录Python:"redirect_uri的无效参数值:缺少方案:无" [英] Google oauth login Python: "Invalid parameter value for redirect_uri: Missing scheme: None"

问题描述

这是我的代码:

flow = OAuth2WebServerFlow(client_id='XXXXXX',client_secret='XXXXXXXXX',scope='https://www.googleapis.com/auth/userinfo.email',redirect_uri='https://XXXXXXXX.com/oauth2callback')
log.debug(flow.__dict__)
if not self.request.get("code"):
    auth_uri = flow.step1_get_authorize_url()
    log.debug("the link " + auth_uri)
    self.redirect(auth_uri)
else:
    code = self.request.get("code")
    log.debug("code=>"+str(code))
    credentials = flow.step2_exchange(str(code))
    http = httplib2.Http()
    http = credentials.authorize(http)
    log.info('authorisation completed')
    service = build('gmail', 'v2', http=http)
    self.render_json(service.__dict__)

所有这些之后，进行编码.我收到如下错误:

After all this, code. I am getting an error as below:

Failed to retrieve access token: {
  "error" : "invalid_request",
  "error_description" : "Invalid parameter value for redirect_uri: Missing scheme: None"
}

回溯错误:

Failed to retrieve access token: {
  "error" : "invalid_request",
  "error_description" : "Invalid parameter value for redirect_uri: Missing scheme: None"
}

任何人都可以帮助我.坚持了两天.

Can anyone help me out. Stuck for a 2 days on this.

推荐答案

这是因为您缺少重定向URI

This is because you are missing the redirect URI

在我的示例中

REDIRECT_URI = 'http://localhost:8000/app'
OAUTH2_SCOPE = 'https://www.googleapis.com/auth/drive.readonly'

flow = flow_from_clientsecrets(CLIENTSECRET_LOCATION, OAUTH2_SCOPE)
flow.redirect_uri = REDIRECT_URI
credentials = flow.step2_exchange(authorization_code)
