# SDK for 微信小程序

相关接口和 SDK for Web 版本相同：

{% content-ref url="/pages/-LdsyyphaBreKun8cXvJ" %}
[SDK for Web](/authing/master/sdk/sdk-for-web.md)
{% endcontent-ref %}

Github 地址：

{% embed url="<https://github.com/Authing/authing-wxapp-sdk>" %}

{% hint style="info" %}
**NOTE!** 在小程序中开发需要在小程序管理后台中配置域名，两个域名分别为：`https://users.authing.cn`和`https://oauth.authing.cn`
{% endhint %}

## **下载代码**

```bash
$ git clone https://github.com/Authing/authing-wxapp-sdk
```

## **引入文件**

然后将下载的代码内的 authing 文件夹移动到你的项目目录下，之后使用 require 引入

```javascript
var Authing = require('path/to/authing/authing.js')
```

## **使用**

注意，在使用小程序 SDK 时，可以不传入 email 和 password 参数，取而代之的是 unionid，就是从小程序获取的 openid 或 unionid。

```javascript
var auth = new Authing({
	clientId: 'your_client_id',
	secret: 'your_app_secret'
});

auth.then(function(validAuth) {

	//验证成功后返回新的 authing-js-sdk 实例(validAuth)，可以将此实例挂在全局

	validAuth.login({
		unionid: 'test@testmail.com',
	}).then(function(user) {
		console.log(user);	
	}).catch(function(error) {
		console.log(error);	
	});
	
}).catch(function(error) {
	//验证失败
	console.log(error);
});
```
