Nodejs express框架实现文件上传

1、使用Express、Nodejs服务器上传文件时出现Unexpected field，参考https://blog.youkuaiyun.com/qq_37540004/article/details/60963039
使用

var multipart = require(‘connect-multiparty’); //在处理模块中引入第三方解析模块
var multipartMiddleware = multipart();

安装connet-multiparty ，npm install connet-multiparty --save 或者 cnpm install connet-multiparty

var multipart = require(‘connect-multiparty’);
var multipartMiddleware = multipart();
app.post(’/upload’, multipartMiddleware, function(req, resp) {
console.log(req.body, req.files);
// don’t forget to delete all req.files when done
