spring boot整合第三方微信开发工具 weixin-java-miniapp 实现小程序微信登录
有时候项目需要用到微信登录或获取用户的手机号码，weixin-java-miniapp是一个好用的第三方工具，不用我们自己写httpcline调用。
导入jar包
<dependency> <groupId>com.github.binarywang</groupId> <artifactId>weixin-java-miniapp</artifactId> <version>4.1.0</version> </dependency>
添加一个resource.properties文件，写上小程序的appid和secret
wx.miniapp.appid: xxxxxxxxxxxx wx.miniapp.secret: xxxxxxxxxxxxxxxxxxxxxxxxxx wx.miniapp.msgDataFormat: JSON
添加两个配置文件
WxMaProperties.java
@ConfigurationProperties(prefix = "wx.miniapp")
public class WxMaProperties {
/**
* 设置微信小程序的appid
*/
private String appid;
/**
* 设置微信小程序的Secret
*/
private String secret;
/**
* 消息格式，XML或者JSON
*/
private String msgDataFormat;
public String getAppid() {
return appid;
}
public void setAppid(String appid) {
this.appid = appid;
}
public String getSecret() {
return secret;
}
public void setSecret(String secret) {
this.secret = secret;
}
public String getMsgDataFormat() {
return msgDataFormat;
}
public void setMsgDataFormat(String msgDataFormat) {
this.msgDataFormat = msgDataFormat;
}WxMaConfiguration.java
@Configuration
@EnableConfigurationProperties(WxMaProperties.class)
public class WxMaConfiguration {
@Bean
public WxMaService wxMaService(WxMaProperties properties) {
WxMaDefaultConfigImpl config = new WxMaDefaultConfigImpl();
config.setAppid(properties.getAppid());
config.setSecret(properties.getSecret());
config.setMsgDataFormat(properties.getMsgDataFormat());
WxMaService service = new WxMaServiceImpl();
service.setWxMaConfig(config);
return service;
}
}
如何使用
@Autowired
private WxMaService wxMaService;
@ApiOperation("获取微信授权信息")
@ApiImplicitParam(name = "code",value = "前端授权登录后传来的code", required = true,paramType = "query")
@RequestMapping(value = "/wechatSession", method = RequestMethod.POST)
@ResponseBody
public ResponseResult wechatSession(@RequestParam String code) {
//获取openId、unionid、session_key
WxMaJscode2SessionResult sessionInfo = wxMaService.getUserService().getSessionInfo(code);
}
@ApiOperation("小程序手机号登录")
@ApiImplicitParams({
@ApiImplicitParam(name = "sessionKey", value = "sessionKey", paramType = "query", dataType = "string", required = true),
@ApiImplicitParam(name = "encryptedData", value = "加密串", paramType = "query", dataType = "string", required = true),
@ApiImplicitParam(name = "iv", value = "偏移量", paramType = "query", dataType = "string", required = true)
})
@RequestMapping(value = "/wechatLogin", method = RequestMethod.POST)
@ResponseBody
public ResponseResult wechatLogin(HttpServletRequest request,
@RequestParam @NotBlank(message = "sessionKey不能为空") String sessionKey,
@RequestParam @NotBlank(message = "加密串不能为空") String encryptedData,
@RequestParam @NotBlank(message = "偏移串不能为空") String iv) {
WxMaPhoneNumberInfo phoneInfo = wxMaService.getUserService().getPhoneNoInfo(sessionKey, encryptedData, iv);
return phoneInfo.getPurePhoneNumber();
}
