我已经尝试通过golang.com/x/oauth2库成功使用 OAuth 进行身份验证。
// provider variable is oauth2.Config
// scope is: https://www.googleapis.com/auth/userinfo.email
url := provider.AuthCodeURL(``) // redirect URL
从客户端重定向回来后,我auth_code成功发送
auth_code := ctx.Request.URL.RawQuery // code=XXXX
if len(auth_code) > 5 {
auth_code = auth_code[5:] // XXXX
}
tok, err := provider.Exchange(oauth2.NoContext, auth_code)
if err == nil {
client := provider.Client(oauth2.NoContext, tok)
email_url := `https://www.googleapis.com/auth/userinfo.email`
//Log.Describe(client)
response, err := client.Get(email_url)
if err == nil {
ctx.Render(`login_oauth`, response)
//handled = true
}
}
//Log.Describe(err)
我没有发现任何可以告诉response(Body空的)电子邮件部分的内容:

第一个问题,如何正确获取邮箱?不使用 Google+ API。
