Uncaught (in promise) Error: Request failed with status code 415
错误如下图
前端代码（vue）：
var data = {username: this.loginForm.username,password: this.loginForm.password}this.$axios.post(this.GLOBAL.host + '/login', this.$qs.stringify(data)).then(res => {// Determine the login status based on the returned resultsconsole.log(res)})
后台代码（springboot）：
@Controller
public class LoginController {@Autowiredprivate LoginService loginService;@RequestMapping(value = "/login",method = RequestMethod.POST)@ResponseBodypublic Object login(@RequestBody UserDTO userDTO){return loginService.login(userDTO.getUsername(),userDTO.getPassword());}
}
错误原因：
当我们使用application / x-www-form-urlencoded时，Spring并不将其理解为RequestBody。因此，如果我们想要使用它，我们必须删除@RequestBody注释。
然后尝试以下方法：
修改LoginController代码：
@Controller
public class LoginController {@Autowiredprivate LoginService loginService;@RequestMapping(value = "/login",method = RequestMethod.POST,consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE,produces = {MediaType.APPLICATION_ATOM_XML_VALUE, MediaType.APPLICATION_JSON_VALUE})@ResponseBodypublic Object login(UserDTO userDTO){return loginService.login(userDTO.getUsername(),userDTO.getPassword());}
}
重新试一下~~访问成功，问题解决啦
