阿里云文档：号码认证SDK_号码认证服务(PNVS)-阿里云帮助中心

对于后端大概流程 前端App会传一个token过来  后端通过下面方法解析  如果解析可以获得号码,说明号码认证成功,如果无法正确解析则认证失败

/*** actoken来换取电话号码* @param token app端用户授权actoken* @return*/public static String getPhone(String token) {DefaultProfile profile = DefaultProfile.getProfile(regionId, accessKeyID, accessKeySecret);//自己阿里云的配置IAcsClient client =new DefaultAcsClient(profile);GetMobileRequest request = new GetMobileRequest();request.setAccessToken(token);//app端传过来的，需要用户授权拿到request.setSysRegionId(regionId);String phone = null;try {GetMobileResponse response = client.getAcsResponse(request);if("OK".equals(response.getCode())) {System.out.println(response.toString());phone = response.getGetMobileResultDTO().getMobile();};System.out.println(new Gson().toJson(response));} catch (ServerException e) {e.printStackTrace();} catch (ClientException e) {System.out.println("ErrCode:" + e.getErrCode());System.out.println("ErrMsg:" + e.getErrMsg());System.out.println("RequestId:" + e.getRequestId());}return phone;}
