com.github.binarywang

weixin-java-miniapp

4.0.0

application.yml配置

wechat:

miniapp:

    appId: wx701*********

    appSecret: a374ae************************

WxMaConfiguration

/**

* 微信小程序

*/

@Data

@Configuration

@ConditionalOnClass(WxMaService.class)

@ConfigurationProperties(prefix ="wechat.miniapp")

public class WxMaConfiguration {

/**

* 设置微信小程序的appId

*/

    private StringappId;

/**

* 设置微信小程序的Secret

*/

    private StringappSecret;

@Bean

@ConditionalOnMissingBean(WxMaService.class)

public WxMaService wxMaService() {

WxMaDefaultConfigImpl config =new WxMaDefaultConfigImpl();

config.setAppid(this.getAppId());

config.setSecret(this.getAppSecret());

WxMaService service =new WxMaServiceImpl();

service.setWxMaConfig(config);

return service;

}

}

使用

public String login(String code, String signature, String rawData, String encryptedData, String iv)throws WxErrorException {

WxMaJscode2SessionResult res =wxMaService.getUserService().getSessionInfo(code);

String sessionKey = res.getSessionKey();

// 用户信息校验

    if (!wxMaService.getUserService().checkUserInfo(sessionKey, rawData, signature)) {

return R.error("微信授权失败");

}

// 解密用户信息

    WxMaUserInfo userInfo =wxMaService.getUserService().getUserInfo(sessionKey, encryptedData, iv);

String openId=userInfo.getOpenId();

return openId;

}
