使用 axios.put [laravel + vuejs 3] 更新模态内的数据时出现错误 422

Question

我正在使用 Laravel + VueJS 3 构建一个小项目，

我使用 axios.put 方法通过模式更新 table 行中的单个用户的详细信息，但是当我在带有 [= 的模式中单击表单的提交按钮时出现问题15=], 即使我为所有输入填充了所有数据，但它仍然说下面的错误，你们能告诉我如何解决这个问题吗？

谢谢！

错误

我的后端：

    public function updateUser(Request $req, User $user)
    {
        $req->validate([
            'name'  =>  'required|string|max:255',
            'email'     =>  'required|email|unique:users,email,' . $user->id,
            'password'  =>  'same:confirmPassword|max:64',
            'roles'     =>  'required',
        ]);

        $input = $req->all();
        if (!empty($input['password'])) {
            $input['password']  =  Hash::make($input['password']);
        } else {
            $input = Arr::except($input, 'password');
        }
        $user->update($input);
        $user->syncRoles($input['roles']);
        return $this->sendResponse($user, 'Updated!');
    }

我的 JS 代码：

import axios from "axios";

let API_URL = "http://localhost:8000";

export default {
  name: "manageUsers",
  components: {},
  data() {
    return {
      users: [],
      userInfo: {
        id: 0,
        name: "",
        username: "",
        phone: "",
        email: "",
        password: "",
      },
    };
  },
  methods: {
    refreshUsers() {
      axios.get(`${API_URL}/api/users/allusers`).then((res) => {
        this.users = res.data.data;
      });
    },
    getUserInfo(user) {
      axios
        .get(`${API_URL}/api/users/show/` + user.id)
        .then((res) => {
          this.userInfo.id = res.data.data.id;
          this.userInfo.name = res.data.data.name;
          this.userInfo.email = res.data.data.email;
          this.userInfo.username = res.data.data.username;
          this.userInfo.phone = res.data.data.phone;
        })
        .catch((error) => {
          console.log("ERRRR:: ", error.response.data);
        });
    },
    updateUser() {
      axios
        .put(`${API_URL}/api/users/update/${this.userInfo.id}`)
        .then((res) => {
          this.refreshUsers();
          alert(res.data);
        })
        .catch((error) => {
          console.log("ERRRR:: ", error.response.data);
        });
    },
  },
  mounted() {
    this.refreshUsers();
  },
};

我认为您没有向 put 调用传递任何参数。 axios docs

示例：

axios.put('https://httpbin.org/put', { hello: 'world' });

当出现此类问题时，您可以随时检查浏览器中的网络选项卡。查看发送到您的服务器的数据。
