上传视频，图片等都是调用wx.uploadFile，后台接口都不用改。.wxml
buttonbindtap"chooseVideo"添加视频/buttonblockwx:if"{{src!''}}"videosrc"{{src}}"/video/block2.
.js
Page({data:{src:''},//选择视频chooseVideo:function(){varthatthiswx.chooseVideo({success:function(res){that.setData({src:res.tempFilePath,})that.uploadvideo();}})},uploadvideo:function(){varsrcthis.data.src;wx.uploadFile({url:'**************/Upload',//服务器接口filePath:src,header:{'content-type':'multipart/form-data'},name:'files',success:function(res){console.log(res.data)},fail:function(){console.log('接口调用失败')}})}})3.
后台接口
