Node.js文件上传

Node.js express使用Multer实现文件上传
html部分

<div>
    <h3>文件上传：</h3>
    选择一个文件上传: <br/>
    <form action=\"/upload\" method=\"post\" enctype=\"multipart/form-data\">
        <input type=\"file\" name=\"content\"/>
        <br/>
        <input type=\"submit\" value=\"上传文件\"/>
    </form>
</div>

Node.js部分
安装multer：npm install multer --save

var express = require(\'express\');
var app = express();
var fs = require(\'fs\');
var multer = require(\'multer\');
var upload = multer({dest: \'uploadFile/\'});
//文件上传
app.post(\'/upload\', upload.any(), function (req, res, next) {
    console.log(req.files[0]);  // 上传的文件信息
    var newFile = \"./uploadFile/\" + req.files[0].originalname;
    fs.readFile(req.files[0].path, function (err, data) {
        fs.writeFile(newFile, data, function (err) {
            if (err) {
                console.log(\"错误：\", err)
            } else {
                let response = {
                    message: \'上传成功\',
                    filename: req.files[0].originalname
                };
                res.json(response);
            }
        });
    })
})
//图片加载,存储在uploadFile下的所有图片
app.get(\'/uploadFile/*\', function (req, res) {
    res.sendFile( __dirname + \"/\" + req.url );
})
