代理不为 GET 请求提供服务:http-proxy-middleware

Question

我正在使用http-proxy-middleware对应用程序进行反向代理，以避免在开发过程中使用CORS。

以下是正在使用的 http-proxy-middleware 的设置。我收到了除 GAT 之外的每种方法的响应。

设置：

路径：服务器/索引.js

import express from 'express';
import path from 'path';
import webpack from 'webpack';
import webpackMiddleware from 'webpack-dev-middleware';
import webpackHotMiddleware from 'webpack-hot-middleware';
import webpackConfig from '../webpack.config.dev';
let proxy = require('http-proxy-middleware');
let app = express();
const compiler = webpack(webpackConfig);
app.use(webpackMiddleware(compiler, {
hot: true,
noInfo: true
}));
app.use(webpackHotMiddleware(compiler));
app.get('/*', (req, res) => {
res.sendFile(path.join(__dirname, './index.html'));
});
let options = {
target: 'https://example.com',
changeOrigin: true,
logLevel:'debug',
ws: true,
onProxyReq: function(proxyReq, req, res) {        
    //  log the req
    console.log('RAW REQUEST from the target', JSON.stringify(req.headers, true, 2));
},
onProxyRes: function (proxyRes, req, res) {
    //  log the response
    console.log('RAW Response from the target', JSON.stringify(proxyRes.headers, true, 2));
}
};
app.use(['/front_end_api/**'], proxy(options));
app.listen(3000, () => console.log('Running on localhost'));

如果我在这里做错了什么，请告诉我。

尝试将您的代理移到 webpack-dev-middleware 之前。http-proxy-middleware存在问题，可能与您所看到的内容有关。https://github.com/chimurai/http-proxy-middleware/issues/199
