nodejs实现文件上传

在使用ant-design的upload上传文件时，前端很好实现，那么我们如何实现node服务端呢？

服务端文件上传实现

var express = require('express');

var fs = require('fs');

var path = require('path');

var multipart = require('connect-multiparty');

var router = express.Router();

/* GET App home page. */

router.get('*', function (req, res) {

  res.sendFile(path.resolve('./', 'index.html'));

});

router.post('/upload', multipart(), function (req, res) {

  //获得文件名

  var filename = req.files.files.originalFilename || path.basename(req.files.files.path);

  //复制文件到指定路径

  var targetPath = './public/uploads/' + filename;

  //复制文件流

  fs.createReadStream(req.files.files.path).pipe(fs.createWriteStream(targetPath));

  //响应ajax请求，告诉它图片传到哪了

  res.json({ code: 200, data: { url: 'http://' + req.headers.host + '/public/uploads/' + filename } });

});

前端代码

class ManageWork extends React.Component {

  handleUpload(e) {

    if (e.file.status === 'done') {

      this.setState({ projectImage: e.file.response.data.url })

    }

  }

  render() {

  	return (

  		<div>

  			<Upload name="files" action="/upload" listType="picture"

				  onChange={e=>this.handleUpload(e)}>

				  <Button type="ghost">

				    <Icon type="upload" /> 点击上传

				  </Button>

				</Upload>

				<a href={this.state.projectImage} target="_blank" className="upload-example">

				  <img src={this.state.projectImage} />

				  <span>缩略图</span>

				</a>

  		</div>

  	)

  }

}
