uniapp --request请求封装，uploadFile上传文件封装

request.js

module.exports.sendRequest = sendRequest

main.js

import Vue from 'vue'

vue中使用—request

getData(){
				this.$http.sendRequest(
				    '/wms/home/homepage',//url地址
					"GET",//请求方式
				    {   //请求的参数
						userId:this.userid,
					},
				).then(res=>{//请求成功

						this.$nextTick(function() {
							this.url=res.data.data.user.avatar
						});
						// this.$set(this.url,res.data.data.user.avatar)
						console.log(this.url)	
					}	
				}).catch(err=>{
					console.log(err)
				});
			},
			

vue中使用—UploadFile
可上传多张图片

openChooseImg(){
				let _this=this
				uni.chooseImage({
					count: 3, //默认9
					// sizeType: ['compressed'], //可以指定是原图还是压缩图，默认二者都有
					// sourceType: ['album','camera'], //从相册选择，和摄像头功能，默认二者都有
					// name:'file',
					success: res=> {
						res.tempFilePaths.forEach(function(item,index){
							let img=res.tempFilePaths[0]
							console.log(img)
							_this.$http.sendUploadFile(
								'/wms/Print/filesUpload',
								item,
								'file',
								{detail_id:1}
							).then(res=>{
								console.log(res.data)
								console.log(JSON.parse(res.data).data)
								_this.imgNewUrl=JSON.parse(res.data).data
							}).catch(err=>{
							})
						})
