Google 如何申请客户端 ID 并调试代码？

<template>
<view>
<button v-google-signin-button="ClientId">谷歌登录</button>
</view>
</template>

//用自定义指令方式实现
import GoogleSignInButton from '@/plugin/googleSign.js'
export default {
data(){
return {
ClientId:'' //刚才申请的客户端ID
}
},
directives: {
GoogleSignInButton
},
methods:{
OnGoogleAuthSuccess(idToken){
cosnole.log(idToken);
//成功打印出来idToken就可以传给后端解析了
},
OnGoogleAuthFail(error) {
console.log(error)
},
}
}
