3, use wx.miniapp.registOpenURL Listen to open via file app The events of

  wx.miniapp.registOpenURL ((param) => {

wx.miniapp.copyNativeFileToWx({
        nativeFilePath: param.data.url,

          console.log('copyNativeFileToWx success', res)
        },
        fail(e) {
          console.log('copyNativeFileToWx fail', e)
        }
      })

Combined with the above steps, the complete example is as follows:

wx.miniapp.registOpenURL ((param) => {
    console.log('regsitOpenUrl',  param)
    if (param.data.isFile) {
      wx.miniapp.copyNativeFileToWx({
        nativeFilePath: param.data.url,
        success(res) {
          console.log('copyNativeFileToWx success', res)
        },
        fail(e) {
          console.log('copyNativeFileToWx fail', e)
        }
      })
    }
