同时上传多张图片，上传失败了没有触发回调方法 failCallBack(clientException, serviceException) {}

[0FengQiang0]

这是我的flutter运行环境： [✓] Flutter (Channel stable, 3.7.0, on macOS 12.5 21G72 darwin-arm64, locale zh-Hans-CN) [✓] Android toolchain - develop for Android devices (Android SDK version 33.0.1) [✓] Xcode - develop for iOS and macOS (Xcode 14.1) [✓] Chrome - develop for the web [✓] Android Studio (version 2021.3) [✓] Connected device (5 available)

上传对象我调用了 upload 方法，因为我需要一次上传多张图片，因此我在一个for循环里调用 upload，希望能上传多张图片。

类似于这样： for(PhotoSelectModel photoModel in _photoList) { upload(photoModel.imgFile.path); }

void upload( String? pickFilePath, { String? bucket, Function(dynamic data)? successBlock, Function(dynamic error)? errorBlock, }) async { try { String tmp_bucket = ""; if(bucket != null) { tmp_bucket = bucket; }else if(_bucket is String && _bucket.isNotEmpty) { tmp_bucket = _bucket; }else { await beginGetTencentCosConfigFromServer(); tmp_bucket = _bucket; } if(tmp_bucket.isEmpty) { return; }

  print("拿到 bucket 啦!!!!! $tmp_bucket");

  if (pickFilePath == null) {
    print("错误信息：请先选择需要上传的文件");
    return;
  }
  //对象在存储桶中的位置标识符，即称对象键
  var time = DateTime.now();
  String tStr = "${time.year.toString()}${time.month.toString().padLeft(2,"0")}${time.day.toString().padLeft(2,"0")}";
  var cosPath =
      "/img/frame/${tStr}/" + "${pickFilePath!.split("/").last}";
  cosPath =
      "/img/frame/${tStr}/" + "${DateTime.now().microsecondsSinceEpoch}.jpg";
  CosTransferManger cosTransferManger = await getTransferManger();
  // 上传成功回调
  successCallBack(result) {
    print("文件已上传到COS：$cosPath");
    if(successBlock!=null) {
      if(result!=null)
      {
        successBlock(result);
      }
      else {
        String resultStr = "https://${tmp_bucket}.cos.${TestConst().PERSIST_BUCKET_REGION}.myqcloud.com"
        + cosPath;
        successBlock(resultStr);
      }
    }
  }
  //上传失败回调
  failCallBack(CosXmlClientException? clientException,
      CosXmlServiceException? serviceException) {
    String error_str = "";
    if (clientException != null) {
      error_str = clientException.toString();
      print("错误信息：$error_str");
      print(clientException);
    }
    if (serviceException != null) {
      error_str = serviceException.toString();
      print("错误信息：$error_str");
      print(serviceException);
    }
    if(errorBlock!=null) {
      errorBlock(error_str);
    }
  }
  //上传状态回调
  stateCallback(state) {
    _state = state;
    print("上传状态回调：$_state");
  }
  //上传进度回调
  progressCallBack(complete, target) {
    _complete = complete;
    _target = target;
    print("上传进度回调(complete)：$_complete");
    print("上传进度回调(target)：$_target");
  }
  //初始化分块完成回调
  initMultipleUploadCallback(
      String bucket, String cosKey, String uploadId) {
    _uploadId = uploadId;
    print("分块完成回调(uploadId)：$_uploadId");
  }
  //开始上传
  print("~~~~~~~~~~~~~~~~~~~~~~~~~~~~  开始上传  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~");
  _transferTask = await cosTransferManger.upload(tmp_bucket, cosPath,
      filePath: pickFilePath,
      uploadId: _uploadId,
      resultListener: ResultListener(successCallBack, failCallBack),
      stateCallback: stateCallback,
      progressCallBack: progressCallBack,
      initMultipleUploadCallback: initMultipleUploadCallback);
} catch (e) {
  print("出错了~~：${e.toString()}");
  print(e);
}

}

只有其中一张图片上传成功，并且触发了 successCallBack(result) {} 其他图片应该都上传失败了，有打印日志： [Info]任务完成的回调 didCompleteWithError response = <NSHTTPURLResponse: 0x2824b3540> { URL: https://games-1302594061.cos.ap-nanjing.myqcloud.com/img/frame/20230319/1679221450034901.jpg } { Status Code: 200, Headers { Connection = ( "keep-alive" ); "Content-Length" = ( 0 ); Date = ( "Sun, 19 Mar 2023 10:24:13 GMT" ); Etag = ( "\"f11911b1f33149ad52412b85f213d822\"" ); Server = ( "tencent-cos" ); "x-cos-hash-crc64ecma" = ( 14973353465238670525 ); "x-cos-request-id" = ( NjQxNmUyY2NfYTAxNzcxMDlfOWRmYl8zZGUyOTU3 ); "x-cos-storage-class" = ( STANDARD ); } } error =

这应该是 QCloudHTTPSessionManager.m 这个文件里的一个方法打印的日志

• (void)URLSession:(NSURLSession )session task:(NSURLSessionTask )task didCompleteWithError:(NSError *)error { QCloudLogInfo(@"任务完成的回调 didCompleteWithError response = %@ error = ", task.response, error); }

但是我的 flutter 项目里的 failCallBack(CosXmlClientException? clientException, CosXmlServiceException? serviceException) {} 这个上传失败的回调方法没有被触发。

简而言之：就是上传多张图片，有图片上传失败了，但是失败的回调方法没有执行。

附上我的项目里上传多个对象的情形：

我检查了一下代码，是我自己调用方式的问题

我也遇到这个问题了，你怎么解决的
