http-proxy-middleware 代理在 React js 和 Spring 引导项目中不起作用。 GET API is return 415 状态错误

Question

我正在使用 http-proxy-middleware 中间件。 Content-Type: application/json 必须在 API 的 header 中加上 postman 执行。我在 React 中添加了 API 的 header 配置。

我认为错误是因为我没有正确发送 headers。其实我不知道。请帮助我。

谢谢

Spring开机

MovieController.java

@RestController
@RequestMapping("/movie")
public class MovieController {

    @Autowired
    private IMovieService movieService;

    @GetMapping(value = "/fetchAllMovieList", produces = MediaType.APPLICATION_JSON_VALUE, consumes = MediaType.APPLICATION_JSON_VALUE)
    public ResponseEntity<List<Movie>> fetchAllMovieList() {
        return new ResponseEntity<>(movieService.fetchAllMovieList(), HttpStatus.OK);
    }
}

反应

movieAction.js

import {API_BASE} from "../config/env";
import axios from 'axios';

const headers = {
    'Content-Type': 'application/json;charset=UTF-8',
    "Access-Control-Allow-Origin": "*",
    "Accept": "application/json"
}

export function fetchMovies() {
    return dispatch => {
        dispatch({
            type: "FETCH_MOVIES",
            payload: axios.get(`${API_BASE}/movie/fetchAllMovieList`, {
                headers: headers
            }).then(response => console.log("Action/moviesAction.js -> response -> ", response))
        })
    }
}

setupProxy.js

import {API_BASE} from "./env";
const createProxyMiddleware = require("http-proxy-middleware");

module.exports = function (app) {
    app.use(
        createProxyMiddleware("/movie/fetchAllMovieList",{
            target: `${API_BASE}`,
            changeOrigin: true
        })
    );
};

env.js

export const API_BASE = "http://localhost:8080";

控制台中的结果

GET http://localhost:8080/movie/fetchAllMovieList 415

我仔细查看了代码，发现了很多错误。这是真的。

env.js

module.exports = {
  API_BASE: "http://localhost:8000",
};

将此添加到 package.json

"proxy":"http://localhost:8000",

setupProxy.js

const { createProxyMiddleware } = require("http-proxy-middleware"); // import module
const { API_BASE } = require("./env");

module.exports = function (app) {
  app.use(
    "/movie/",
    createProxyMiddleware({
      target: API_BASE,
      changeOrigin: true,
    })
  );
};

movieAction.js

import axios from "axios";

const headers = {
  "Content-Type": "application/json;charset=UTF-8",
  "Access-Control-Allow-Origin": "*",
  Accept: "application/json",
};

export function fetchMovies() {
  console.log("action run...");
  return async (dispatch) => {
    console.log("async action run..");

    const response = await axios.get(`/movie/fetchAllMovieList`, {
      headers: headers,
    });

    console.log(response.data);

    dispatch({
      type: "FETCH_MOVIES",
      payload: response.data,
    });
  };
}

我和马赫迪解决了那个问题。我们错过了 data:{} 部分。我在 headers 下添加：headers, 并混合了他和我的代码。我要分享独奏。

moviesAction.js

import axios from 'axios';

const headers = {
    'Content-Type': 'application/json;charset=UTF-8',
    "Access-Control-Allow-Origin": "*",
    Accept: "application/json"
}

export function fetchMovies() {
    return async dispatch => {
        const response = await axios.get(`/movie/fetchAllMovieList`, {
            headers: headers,
            data: {}
        });

        console.log("Action/moviesAction.js -> response -> ", response);

        dispatch({
            type: "FETCH_MOVIES",
            payload: response.data,
        });
    }
}

setupProxy.js

import {API_BASE} from "./env";
const {createProxyMiddleware} = require("http-proxy-middleware");

module.exports = function (app) {
    app.use("/movie/fetchAllMovieList",
        createProxyMiddleware({
            target: `${API_BASE}`,
            changeOrigin: true
        })
    );
};

env.js

export const API_BASE = "http://localhost:8080";

在package.json

中添加代理

  "name": "movie-frontend",
  "version": "0.1.0",
  "private": true,
  **"proxy":"http://localhost:8080",**
  "dependencies": {

http-proxy-middleware proxy is not working in React js and Spring Boot project. GET API is return 415 status error

proxy
