#### 按照上面的步骤成功申请到客户端ID以后，就可以在代码中测试了，下面是代码实例

```js
<template>
    <view>
        <button v-google-signin-button="ClientId">谷歌登录</button>
    </view>
</template>
```
---
```js
//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)
        },
    }
}
```
