 */
@RestController
@RequestMapping("test")
public class ConfirmController {
    @Autowired
    private ConfirmService confirmService;

    @GetMapping("/init")
    public void init() {
        String certifyId = confirmService.getCertifyId("", "");
        String urlBycertifyId = confirmService.getUrlByCertifyId(certifyId);
        System.out.println(certifyId);
        System.out.println(urlBycertifyId);
    }

    @GetMapping("/response")
    public boolean response() {
        boolean b = confirmService.ifPassed("7c184ef960c5661f1e54e7d799e9cda3");
        System.out.println("b:" + b);
        return b;
    }

}

init执行结果：

调用成功
certifyId为:..................
开始认证服务调用成功
certifyUrl为:https://openapi.alipay.com/gateway.do?alipay_sdk=alipay-sdk-java-..............................

response执行结果:

调用成功
认证成功！
b:true
