springboot+vue+jwt做一个登录界面，如何用Postman测试接口

@RestController
public class UserController {

    @Autowired
    private UserService userService;

    @PostMapping("/login")
    public CommonResult login(@RequestParam("user") User user){

        boolean success = userService.login(user);

        CommonResult cr = new CommonResult(success);
        return cr;

    }

    @PostMapping("/register")
    public Integer register(@RequestParam("user") User user){

        int cnt = userService.register(user);
//        boolean is = (cnt == 1 ? true : false);
//        CommonResult cr = new CommonResult(is);
        return cnt;
    }

}
