Node.js——异步上传文件

前台代码

submit() {var file = this.$refs.fileUpload.files[0];var formData = new FormData();formData.append("file", file);formData.append("username", this.username);formData.append("password", this.password);axios.post("http://127.0.0.1:3000", formData).then(res => {console.log(res);});
}

后台代码

app.use(function (req, res) {var form = new formidable.IncomingForm();form.uploadDir = path.join(__dirname, 'uploads')form.parse(req, function (err, fields, files) {fs.rename(files.file.path, path.join(__dirname, 'uploads', files.file.name), function (err) {if (!err) {return res.end('ok')}res.end('err')})
    });
})

 注意

  • 前端利用formData才能拿到file数据,这是xhr异步上传文件提供的接口
  • 后台代码如果不使用formidable这个包,那么对接受过来的二进制数据自己处理是非常麻烦的
