解析Google加登录

Question

我正在使用Parse,用户可以使用Facebook,Twitter和Google+登录.截至目前,只有Facebook和Twitter功能齐全.

我已设法通过以下方式使用Facebook和Twitter登录:

private void onLoginButtonClicked() {
        LoginActivity.this.progressDialog = ProgressDialog.show(
                LoginActivity.this, "", "Logging in...", true);
        List<String> permissions = Arrays.asList("public_profile", "user_about_me",
                "user_relationships", "user_birthday", "user_location");
        ParseFacebookUtils.logIn(permissions, this, new LogInCallback() {
            @Override
            public void done(ParseUser user, ParseException err) {
                LoginActivity.this.progressDialog.dismiss();
                if (user == null) {
                    Log.d(IntegratingFacebookTutorialApplication.TAG,
                            "Uh oh. The user cancelled the Facebook login.");
                } else if (user.isNew()) {
                    Log.d(IntegratingFacebookTutorialApplication.TAG,
                            "User signed up and logged in through Facebook!");
                    showUserDetailsActivity();

                } else {
                    Log.d(IntegratingFacebookTutorialApplication.TAG,
                            "User logged in through Facebook!");
                moodpage();             

                }
            }
        });
    }

    private void onTwitterButtonClicked() {
        ParseTwitterUtils.logIn(this, new LogInCallback() {
              @Override
              public void done(ParseUser user, ParseException err) {
                if (user == null) {
                  Log.d("MyApp", "Uh oh. The user cancelled the Twitter login.");
                } else if (user.isNew()) {
                  Log.d("MyApp", "User signed up and logged in through Twitter!");
                  showUserDetailsActivity();        
                  } else {
                  Log.d("MyApp", "User logged in through Twitter!");
                  moodpage();               }
              }

            });
    }

我试图通过解析来解决这个问题.有人建议我查看Parse Rest API,但是,我不熟悉它,需要更多的指导.

任何澄清将不胜感激.

据此：

和这个：

https://parse.com/tutorials/adding-third-party-authentication-to-your-web-app

以及我对他们的理解

在使用 Google+ / Github / 成功登录后，您只需要在应用程序或云/后端中使用某种算法生成密码

一个简单的实现（但将其放在您的应用程序中并不安全）：

// given Google Plus login (Using their Api) i.e. no Parse yet at this point
int id = 12345; // assume that this is  google+ id (After successfully logging in)

ParseUser user = new ParseUser();
user.setUsername("google-plus-" + String.valueOf(id));
user.setPassword(hashMyPassword(id)); // Create password based on the id
user.setEmail("email.from.google.plus.login@gmail.com");

user.signUpInBackground(new SignUpCallback() {
  public void done(ParseException e) {
    if (e == null) {
      // Hooray! Let them use the app now.
    } else {
      // Sign up didn't succeed. Look at the ParseException
      // to figure out what went wrong
    }
  }
});

该解决方案的一个重要事项是：

仅使用基于应用程序中的 ID 的 ID/密码是不安全的，更好的解决方案是将 Google+ 令牌/用户 ID 发送到后端/云，然后后端/云验证此令牌/ID 是否有效，然后创建用户名/密码，并与 Parse User 交换。

我希望你明白了。
