小程序上传文件

1.先选择图片然后上传到云存储

 //选择图片
    wx.chooseImage({
      count: 1,
      sizeType: ['compressed'],
      sourceType: ['album', 'camera'],
      success:(res)=>{
            wx.showLoading({
              title: '上传中',
            })
            //选中图片的路径
        const filePath = res.tempFilePaths[0]
        //上传图片到云存储中的路径
        const cloudPath = `my-image${filePath.match(/\.[^.]+?$/)[0]}`
        wx.cloud.uploadFile({
          filePath,
          cloudPath
        }).then(res=>{
          wx.hideLoading()
            app.globalData.fileID = res.fileID
            app.globalData.cloudPath = cloudPath
            app.globalData.imagePath = filePath
            wx.navigateTo({
              url: '../storageConsole/storageConsole'
            })
        }).catch(err=>{
          wx.hideLoading()
            console.error('[上传文件] 失败：', e)
            wx.showToast({
              icon: 'none',
              title: '上传失败',
            })
        })

获取图片的临时链接:

 //从云存储获取临时url
    const fileid = "cloud://dev-0g4h9exve5c944d3.6465-dev-0g4h9exve5c944d3-1306228026/my-image.png"
    wx.cloud.getTempFileURL({
      fileList:[fileid]
    }).then(res=>{
      console.log(res)
      let image = res.fileList[0].tempFileURL
      console.log(image)
    })

删除文件

  //删除文件
        const fileid = "cloud://dev-0g4h9exve5c944d3.6465-dev-0g4h9exve5c944d3-1306228026/my-image.png"
        wx.cloud.deleteFile({
          fileList:[fileid]
        }).then(res=>{
          console.log(res)
        }).catch(err=>{
          console.log(err)
        })
