如何在react-slingshot (由coryhouse)中启用代理，以便我可以调用我的Django REST API？

Question

我有一个运行在端口8050上的Django开发服务器，其中有几个REST，我希望为我的React应用程序提供服务，该应用程序由react-slingshot组成，在localhost:3002上运行。

我想要的是让我的Javascript代码，比如fetch('api/v1/employees')，实际调用localhost:8050而不是localhost:3002。

我看到raythree in a github discussion能够找到我的问题的解决方案，但是，我无法让他的解决方案工作。我完全按照他的方式实现了他的建议，但代码表现得好像我根本没有做任何更改。

下面是我在tools/srcServer.js中的代码现在的样子：

// This file configures the development web server
// which supports hot reloading and synchronized testing.

// Require Browsersync along with webpack and middleware for it
import browserSync from 'browser-sync';
// Required for react-router browserHistory
// see https://github.com/BrowserSync/browser-sync/issues/204#issuecomment-102623643
import historyApiFallback from 'connect-history-api-fallback';
import webpack from 'webpack';
import webpackDevMiddleware from 'webpack-dev-middleware';
import webpackHotMiddleware from 'webpack-hot-middleware';
import config from '../webpack.config.dev';
import proxy from 'http-proxy-middleware';

const bundler = webpack(config);

const serverProxy = proxy('/api', {
  target: "http://0.0.0.0:8050",
  changeOrigin: true, // set true for hosted sites
  logLevel: 'debug'
});

// Run Browsersync and use middleware for Hot Module Replacement
browserSync({
  port: 3000,
  ui: {
    port: 3001
  },

  server: {
    baseDir: 'src',

    middleware: [
      historyApiFallback(),

      webpackDevMiddleware(bundler, {
        // Dev middleware can't access config, so we provide publicPath
        publicPath: config.output.publicPath,

        // These settings suppress noisy webpack output so only errors are displayed to the console.
        noInfo: true,
        quiet: false,
        stats: {
          assets: false,
          colors: true,
          version: false,
          hash: false,
          timings: false,
          chunks: false,
          chunkModules: false
        }

        // for other settings see
        // https://webpack.js.org/guides/development/#using-webpack-dev-middleware
      }),

      // bundler should be the same as above
      webpackHotMiddleware(bundler),

      serverProxy,
    ]
  },

  // no need to watch '*.js' here, webpack will take care of it for us,
  // including full page reloads if HMR won't work
  files: [
    'src/*.html'
  ]
});

我想通了！显然，在数组中，serverProxy需要在 webpackDevMiddleware和webpackHotMiddleware之前被索引为middleware！

// This file configures the development web server
// which supports hot reloading and synchronized testing.

// Require Browsersync along with webpack and middleware for it
import browserSync from 'browser-sync';
// Required for react-router browserHistory
// see https://github.com/BrowserSync/browser-sync/issues/204#issuecomment-102623643
import historyApiFallback from 'connect-history-api-fallback';
import webpack from 'webpack';
import webpackDevMiddleware from 'webpack-dev-middleware';
import webpackHotMiddleware from 'webpack-hot-middleware';
import config from '../webpack.config.dev';
import proxy from 'http-proxy-middleware';

const bundler = webpack(config);

const serverProxy = proxy('/api', {
  target: "http://0.0.0.0:8050",
  changeOrigin: true, // set true for hosted sites
  logLevel: 'debug'
});

// Run Browsersync and use middleware for Hot Module Replacement
browserSync({
  port: 3000,
  ui: {
    port: 3001
  },

  server: {
    baseDir: 'src',

    middleware: [
      historyApiFallback(),

      // The order of serverProxy is important. It will not work if it is indexed
      // after the webpackDevMiddleware in this array.
      serverProxy,

      webpackDevMiddleware(bundler, {
        // Dev middleware can't access config, so we provide publicPath
        publicPath: config.output.publicPath,

        // These settings suppress noisy webpack output so only errors are displayed to the console.
        noInfo: true,
        quiet: false,
        stats: {
          assets: false,
          colors: true,
          version: false,
          hash: false,
          timings: false,
          chunks: false,
          chunkModules: false
        }

        // for other settings see
        // https://webpack.js.org/guides/development/#using-webpack-dev-middleware
      }),

      // bundler should be the same as above
      webpackHotMiddleware(bundler),
    ]
  },

  // no need to watch '*.js' here, webpack will take care of it for us,
  // including full page reloads if HMR won't work
  files: [
    'src/*.html'
  ]
});
