XMPP Google Talk X-OAUTH2登录名需要用户名 [英] XMPP Google Talk X-OAUTH2 login requires username

问题描述

我正在为使用相对较新的X-OAUTH2机制的Google Talk实施XMPP客户端.我的想法是，我不需要存储用于对服务进行身份验证的用户名或密码.但是，用于X-OAUTH2身份验证的 Google文档指出，这是初始的<auth>请求制作:

I'm implementing an XMPP client for Google Talk that is using the relatively new X-OAUTH2 mechanism. I had the idea that I shouldn't need to store either username or password for the authentication to the service. However, Google's documentation for the X-OAUTH2 authentication states this is the initial <auth> request to make:

<auth xmlns="urn:ietf:params:xml:ns:xmpp-sasl"
    mechanism="X-OAUTH2"
    auth:service="oauth2"
    xmlns:auth="http://www.google.com/talk/protocol/auth">
  base64("\0" + user_name + "\0" + oauth_token)
</auth>

请注意，它要求将"user_name"与令牌一起发送.这里有我想念的东西吗?还是我真的必须在应用程序提示符下输入用户名? (请注意，用户已经通过OAuth2登录以接收访问令牌)

Note that it requires the "user_name" to be sent along with the token. Is there something I'm missing here? Or do I really have to have my application prompt for the username? (Note that the user would already have logged in via OAuth2 to receive the access token)

我不知道有任何其他使用OAuth的服务需要客户端提供用户名.例如，同一应用可以通过XMPP和OAuth2连接到Facebook聊天，而无需在XMPP中提供用户名.

I don't know of any other service that uses OAuth that requires the client to provide a username. For instance, this same app can connect to Facebook Chat via XMPP and OAuth2 without needing the username to be provided in XMPP.

推荐答案

您无需在应用程序中提示输入用户名.只需将"SCOPE"参数指定为"https://www.googleapis.com/auth/userinfo.email"即可. 请参考此.这将为您提供用户的电子邮件ID和令牌.

You don't need to prompt for username in your application. Just specify "SCOPE" parameter as "https://www.googleapis.com/auth/userinfo.email". Refer this. This will give you users email-ID in response along with token.

此链接包含有关Google帐户身份验证和授权的详细说明.您可以在应用程序中使用的getUserInfo()函数中返回用户名和电子邮件ID.
