编写代码时请注意规范，以便于他人理解。另外，您上传时遇到了什么问题？ - Bhumeshwer katre

在这段代码中，Code.WebData为空。此外，视频未能成功发布到服务器上。 - rahul

是的，新数据和WebData都为空。 - rahul

AFNetworking将会提供帮助。 - amar

Answer 1

使用AFNetworking库很容易实现，并且您还可以使用它来跟踪视频上传的进度。您可以从这里下载AFNetworking库。

有关配置AFnetworking，请参阅此链接。

以下代码将用于将视频发送到服务器。

 NSString *videoURL = [[NSBundle mainBundle] pathForResource:@"myVideo" ofType:@"mov"];
NSData *videoData = [NSData dataWithContentsOfURL:[NSURL fileURLWithPath: videoURL]];

AFHTTPClient *httpClient = [AFHTTPClient clientWithBaseURL:[NSURL URLWithString:@"http://www.example.com"]];

NSMutableURLRequest *request = [httpClient multipartFormRequestWithMethod:@"POST" path:@"/videoupload.php" parameters:nil constructingBodyWithBlock:^(id <AFMultipartFormData>formData)
{
    [formData appendPartWithFileData:videoData name:@"file" fileName:@"myVideo.mov" mimeType:@"video/quicktime"];
}];



AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest: request];

[operation setUploadProgressBlock:^(NSInteger bytesWritten,long long totalBytesWritten,long long totalBytesExpectedToWrite)
 {

     NSLog(@"Sent %lld of %lld bytes", totalBytesWritten, totalBytesExpectedToWrite);

 }];

[operation  setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {NSLog(@"Video Uploaded Successfully");}
                                  failure:^(AFHTTPRequestOperation *operation, NSError *error) {NSLog(@"Error : %@",  operation.responseString);}];


[operation start];

我下载了AF Networking的文件。但是没有名为AFHTTPClient的文件。 - rahul

[operation setUploadProgressBlock:^(NSInteger bytesWritten,long long totalBytesWritten,long long totalBytesExpectedToWrite) 现在我只是在这一行中遇到了错误。不兼容的块指针类型，将“void (^) (NSInteger、long long、long long)”发送到类型为“void (^) (NSUInteger、long long、long long)”的参数。 - rahul

注释掉这些代码，这只是为了跟踪进度。我会查看错误的。 - Dilip Manek

你好，Dilip。我正在使用这个Web服务：http://rompio.com/web_service/web.php?method=upload_video&user_id=4，我正在使用你建议的上述代码。但是我没有成功。你能否尝试上传任何视频并帮助我？谢谢。 - rahul

好的，谢谢。我在等朋友。这对我来说非常紧急，我已经尝试了三天。 - rahul

Answer 2

将所选视频的URL存储在某个变量中：

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary<NSString *,id> *)info {
    if ([mediaType isEqualToString:(NSString *)kUTTypeMovie]) {
        selectedVideoURL = info[UIImagePickerControllerMediaURL];
    }
}

对于最新版本的AFNetworking，使用以下代码。

NSMutableDictionary *dictParams1 = [[NSMutableDictionary alloc]init];
[dictParams1 setObject:userID forKey:"userID"];
[dictParams1 setObject:otherparam forKey: "otherparam_Key"];

NSLog(@"REQUEST URL : ------------------ %@", API_URL);
NSLog(@"PARAMETERS : ------------------ %@", dictParams1);

NSString *strFileName = [NSString stringWithFormat:@"%ld.mov", [[NSDate date] timeIntervalSince1970]];
NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:APIAddFeedVideo parameters:dictParams1 constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {

    [formData appendPartWithFileURL:selectedVideoURL name:@"videofile" fileName:strFileName mimeType:@"video/mov" error:nil]; // video/quicktime //video/mp4
} error:nil];

AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];

NSURLSessionUploadTask *uploadTask;
uploadTask = [manager uploadTaskWithStreamedRequest:request progress:^(NSProgress * _Nonnull uploadProgress) {

    // This is not called back on the main queue.
    // You are responsible for dispatching to the main queue for UI updates

    dispatch_async(dispatch_get_main_queue(), ^{
        //Update the progress view
        //[progressView setProgress:uploadProgress.fractionCompleted];
    });
} completionHandler:^(NSURLResponse * _Nonnull response, id  _Nullable responseObject, NSError * _Nullable error) {
    if (error) {
          NSLog(@"Error: %@", error);
    } else {
        NSLog(@"VIDEO UPLOAD RESPONSE : %@ %@", response, responseObject);

    }
}];

[uploadTask resume];
