一、上传图片和上传视频的代码整合

1.将uploadImg()和uploadVideo()整合成uploadFile()

  //上传文件
  uploadFile(tempFile,fileName){    //传递两个参数，tempFile是所选文件的临时路径，fileName是上传到云存储的cloudPath的值
    console.log("要上传文件的临时路径",tempFile)
    let timestamp = (new Date()).valueOf()
    wx.cloud.uploadFile({
      cloudPath: fileName,          //云存储的路径
      filePath: tempFile,           // 文件路径
    }).then(res => {
      console.log("上传成功",res)
      wx.showToast({
        title: '上传成功',
        icon:"success",
        duration:2000
      })
      let that = this
       setTimeout(function(){
        that.setData({
          videoUrl:res.fileID,
          imageUrl:res.fileID
         })
    },2000)
    })
    .catch(err => {
      console.log("上传失败",err);
    })
  }

二、在chooseImg()函数和chooseVideo()函数中分别调用整合后的上传文件函数uploadFile()

1.在chooseImg()函数中调用uploadFile()

  chooseImg(){
    let that = this
    wx.chooseImage({
      count: 1,
      sizeType: ['original', 'compressed'],
      sourceType: ['album', 'camera'],
      success (res) {
        console.log("选择成功",res);
        wx.showLoading({
          title: '上传中',
         })
        // tempFilePath可以作为img标签的src属性显示图片
        const tempFilePaths = res.tempFilePaths 

        //调用uploadImg(tempFile)函数，实现图片上传功能
        //that.uploadImg(tempFilePaths[0])

        //调用uploadFile()实现上传文件功能
        let timestamp = (new Date()).valueOf()
        that.uploadFile(tempFilePaths[0],+timestamp+'.png') //传递两个参数
      }
    })
  }

2.在chooseVideo()函数中调用uploadFile()

  //第一步：选择要上传的视频
  chooseVideo(){
    let that = this
    wx.chooseVideo({
      sourceType: ['album','camera'],
      maxDuration: 60,
      camera: 'back',
      success(res) {
        //console.log(res.tempFilePath);
        console.log("----------",res.tempFilePath);
        wx.showLoading({
          title: '上传中',
         })
      //调用uploadImg(tempFile)函数，实现图片上传功能
      //that.uploadVideo(res.tempFilePath)

      //调用uploadFile()实现上传文件功能
      let timestamp = (new Date()).valueOf()
      that.uploadFile(res.tempFilePath,+timestamp+'.mp4') //传递两个参数
      }
    })
  }
