google-services.json如何替换default_web_client_id？ [英] How does google-services.json replace default_web_client_id?

问题描述

首先，我只想说我有Google Play登录并开始工作。然而，我一直在努力了解特定的代码行是如何工作的。

  GoogleSignInOptions gso = new GoogleSignInOptions.Builder（GoogleSignInOptions.DEFAULT_SIGN_IN） 
 .requestIdToken（getString（R.string.default_web_client_id））
 .requestEmail（）
 .build（）; 
  

我想知道requestIdToken如何获得我的真实clientId。调查：default_web_client_id = 0x7f060035

当我登录R.string.default_web_client_id时，我得到： 2131099701 <当我登录getString（R.string.default_web_client_id）时，我得到：
xxxxxxx-xxxxxxxxx0tfctc0fa0a.apps.googleusercontent.com（我的网站客户端ID）

此ID不在我的字符串或资源文件夹中。但是它在我的google-services.json文件中。

我的问题是getString或default_web_client_id如何解析为Json文件中的clientID？

感谢您的启发！ 解决方案

根据这个你应用gradle插件，然后用JSON的值生成新的xml文件。

First i'd just like to say I have Google play sign in up and working. However I have struggling to understand how a specific line of code works.

GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
                .requestIdToken(getString(R.string.default_web_client_id))
                .requestEmail()
                .build();

I would like to know how requestIdToken is getting my real clientId.
when investigating: default_web_client_id = 0x7f060035

when i log R.string.default_web_client_id i get: 2131099701

when I log getString(R.string.default_web_client_id) i get: xxxxxxx-xxxxxxxxx0tfctc0fa0a.apps.googleusercontent.com(my web client id)

This id is not located in my strings or resources folder. However it is in my google-services.json file.

My question is how is getString or that default_web_client_id resolving into a clientID in a Json File?

Thanks in advance for the enlightenment!

解决方案

According to this you apply gradle plugin which then generates new xml file with values from the JSON
