基于layui文件上传二次封装,修改layui源码实现放弃上传,确保上传接口能通，否则图片不会反显

该组件支持图片、文件上传，具体使用见文档。

一、 文件上传组件

setter.testApi = “http://localhost:8080”

1.引入css文件

<link rel="stylesheet" href="../src/css/layui.css">

<link rel="stylesheet" href="../src/css/upload.css">

<link rel="stylesheet" href="../src/css/font-awesome.min.css">

2.引入js

layui.extend({fileUpload: ‘…/lib/extend/fileUpload’})

3.定义组件容器

4.初始化组件

	fileUpload.init({
		view: '#file-view', //容器id
		items: imgConfig, //配置json
		url: setter.testApi + '/upload/', //上传url
		imgUrl: setter.testApi + '/image/100/200/', //缩略图
		originalUrl: setter.testApi + '/image/0/0/', //原图
		value: items //返显初始参数
	});

(1)配置信息imgConfig格式

    //json格式
    [
      {
        "code": "Business_license",
        "size": 20480,
        "isNeed": "0",
        "name": "营业执照",
        "format": "jpg,png,txt,doc,pdf",
        "disabled": false
      }
   ]

(2)返显初始参数items格式

	//json格式 
	[
		{
			"code": "Business_license",
			"key": "b4141e9e-f8a4-482c-92ea-3b4b063e4c56,
			"type": "image/*",
			"fileName": "营业执照"
		}
	]
