描述 上传视频文件的时候

        在微信开发者工具上传视频没有问题，

        但是下列真机测试时：

        ios端调用wx.uploadvideo时

            1 上传已有视频时 上传失败

            2 上传拍摄视频时 上传成功

        android 没有问题

以下为代码片段 简易demo

index.js

//index.js var app = getApp() var count = 0; Page({   data: {     chooesVideo: '',    //上传视频地址     tipHide: false,     chooseTypeHide: true,   },     /**      * 生命周期函数--监听页面加载      */   onLoad: function (options) {     console.log(options.status)   },   /**      * 生命周期函数--监听页面初次渲染完成      */   onReady: function (res) {     this.videoContext = wx.createVideoContext('prew_video');   },/**    * 上传图片    */   chooseImg: function () {     let that = this     wx.chooseImage({       count: 1, // 默认9       sizeType: ['original', 'compressed'], // 可以指定是原图还是压缩图，默认二者都有       sourceType: ['album', 'camera'], // 可以指定来源是相册还是相机，默认二者都有       success: function (res) {         console.log(res)         var tempFilePaths = res.tempFilePaths         that.data.images = tempFilePaths         // 多图片         // that.data.urls = that.data.urls.concat(tempFilePaths)         // 单图片         that.data.urls = tempFilePaths[0]         that.setData({           images: tempFilePaths[0],           urls: that.data.urls         })         }     })   },     /**    * 上传视频    */   chooseVideo: function () {     let that = this     wx.chooseVideo({       sourceType: ['album', 'camera'],       maxDuration: 60,       camera: 'back',       success: function (res) {         console.log(res.tempFilePath),         that.setData({           chooesVideo: res.tempFilePath         })                    var src = that.data.chooesVideo;         wx.uploadFile({           url: '',//服务器接口           method: 'POST',//这句话好像可以不用           filePath: src,           header: {             'content-type': 'multipart/form-data'           },           name: 'file',//服务器定义的Key值           success: function (res) {             console.log(res)           },           fail: function () {             console.log('接口调用失败')           }         })       }     })         },         /**      * 全屏改变      */   bindVideoScreenChange: function (e) {     var status = e.detail.fullScreen;     var play = {       playVideo: false     }     if (status) {       play.playVideo = true;     } else {       this.videoContext.pause();     }     this.setData(play);   }   })
