React 不会加载本地图像

React won#39;t load local images(React 不会加载本地图像)

问题描述

我正在构建一个小型 React 应用程序，但我的本地图像无法加载.placehold.it/200x200 之类的图像会加载.我想这可能是服务器的问题?

I am building a small react app and my local images won't load. Images like placehold.it/200x200 loads. I thought maybe it could be something with the server?

这是我的 App.js

Here is my App.js

import React, { Component } from 'react';

class App extends Component {
    render() {
        return (
            <div className="home-container">
                <div className="home-content">
                    <div className="home-text">
                        <h1>foo</h1>
                    </div>
                    <div className="home-arrow">
                        <p className="arrow-text">
                            Vzdělání
                        </p>
                        <img src={"/images/resto.png"} />
                    </div>
                </div>
            </div>
        );
    }
}

export default App;

index.js:

import React, { Component } from 'react';
import { render } from 'react-dom';
import { Router, Route, Link } from 'react-router';
import { createHistory } from 'history';
import App from './components/app';

let history = createHistory();

render(
    <Router history={history} >
        <Route path="/" component={App} >
            <Route path="vzdelani" component="" />
            <Route path="znalosti" component="" />
            <Route path="prace" component="" />
            <Route path="kontakt" component="" />
        </Route>
        <Route path="*" component="" />
    </Router>,
    document.getElementById('app')
);

和 server.js:

and server.js:

var path = require('path');
var express = require('express');
var webpack = require('webpack');
var config = require('./webpack.config.dev');

var app = express();
var compiler = webpack(config);

app.use(require('webpack-dev-middleware')(compiler, {
  noInfo: true,
  publicPath: config.output.publicPath
}));

app.use(require('webpack-hot-middleware')(compiler));

app.get('*', function(req, res) {
  res.sendFile(path.join(__dirname, 'index.html'));
});

app.listen(3000, 'localhost', function(err) {
  if (err) {
    console.log(err);
    return;
  }

  console.log('Listening at http://localhost:3000');
});

推荐答案

在使用 Webpack 时，您需要 require 图像以便 Webpack 处理它们，这可以解释为什么外部图像加载而内部执行不是，所以你需要使用 <img src={require('/images/image-name.png')}/> 将 image-name.png 替换为每个图像的正确图像名称.这样 Webpack 就能够处理和替换源 img.

When using Webpack you need to require images in order for Webpack to process them, which would explain why external images load while internal do not, so instead of <img src={"/images/resto.png"} /> you need to use <img src={require('/images/image-name.png')} /> replacing image-name.png with the correct image name for each of them. That way Webpack is able to process and replace the source img.
