## 欢迎来到 weixin4j-wxa
|
||||
微信小程序 API 支持
|
||||
|
||||
### 如何使用
|
||||
|
||||
```java
|
||||
var appId = "YOUR APP ID";
|
||||
var appSecret = "YOUR APP SECRET";
|
||||
var wxAccount = new WeixinAccount(appId, appSecret);
|
||||
var wxa = new WeixinAppFacade(wxAccount);
|
||||
var jsCode = request.getParameter("jsCode");
|
||||
var session = wxa.getLoginApi().jscode2session(jsCode);
|
||||
```
|
||||
|
||||
*更多 API 见 [WeixinAppFacade JavaDoc](apidocs/index.html?com/foxinmy/weixin4j/wxa/WeixinAppFacade.html)。*
|
||||
|
||||
### 解密数据
|
||||
客户端 API
|
||||
[`wx.getUserInfo(Object object)`](https://developers.weixin.qq.com/miniprogram/dev/api/open-api/user-info/wx.getUserInfo.html)
|
||||
[`wx.getUserProfile(Object object)`](https://developers.weixin.qq.com/miniprogram/dev/api/open-api/user-info/wx.getUserProfile.html)
|
||||
等请求后得到的加密数据，可以通过下面的方法来解密。
|
||||
|
||||
客户端将获得的加密数据发往业务服务器，业务服务器收到加密数据后，使用登录 API 获得的 `sessionKey` 解密并进行后续操作：
|
||||
|
||||
```java
|
||||
var encryptedData = request.getParameter("encryptedData");
|
||||
var iv = request.getParameter("iv");
|
||||
var sessionKey = session.getSessionKey();
|
||||
var wxBizDataCrypt = new WXBizDataCrypt(appId, sessionKey);
|
||||
var decryptedData = wxBizDataCrypt.decryptData(encryptedData, iv);
|
||||
```
