如果选择相册文件呢?camera怎么代替呢?

选择相册的时候还是崩溃

 wx.showActionSheet({

      itemList: ['拍照', '相册'],

      success: res => {

        if (res.tapIndex == 0{

          this.setData({

            hidecamera: false,

            hideCoverImage: true,

            hideTakeButton: false

          })

        } else {

          wx.chooseImage({

            sizeType: 'comppressed',

            sourceType: ['album'],

            count: 1,

            complete: res => {

              let img = res.tempFilePaths[0]

              if (!img{

                wx.showModal({

                  showCancel: false,

                  content: '选择图片失败,重新再试~',

                })

                return

              }

              this.upimg(img)

            }

          })

        }

      }

    })
