我正在使用 AFNetworking 上传多个文件。我需要为每个图像发送额外的信息，例如图像宽度/高度。

我以为我会遍历图像并发送它们，但 AFNetworking 并不能很好地处理它。
（我怀疑 AFNetworking 将多个请求合二为一，覆盖了额外的信息）

下面是我的代码。

NSURL *url = [NSURL URLWithString:@URL_BASE];
int count = [imageArray count];

for(int i = 0; i < count; ++i)
 {
     UIImage* image = [imageArray objectAtIndex:i];
     AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:url];
     NSDictionary* params = [NSDictionary dictionaryWithObjectsAndKeys:
                                             [NSNumber numberWithFloat: image.size.width], @"width",
                                             [NSNumber numberWithFloat: image.size.height], @"height",
                                          nil];

     NSMutableURLRequest *request = [httpClient multipartFormRequestWithMethod:@"POST" path:@PATH_ALBUM_IMAGE_UPLOAD parameters:params constructingBodyWithBlock: ^(id <AFMultipartFormData>formData) {
             [formData appendPartWithFileData:imageData name:[NSString stringWithFormat:@"file%d", i]  fileName:@"avatar.jpg" mimeyTpe:@"image/jpeg"];
         }];

     AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
     [operation setUploadProgressBlock:^(NSInteger bytesWritten, long long totalBytesWritten, long long totalBytesExpectedToWrite) {

             [progressView setProgress: totalBytesWritten*1.0f / totalBytesExpectedToWrite animated: YES];
             NSLog(@"Sent %lld of %lld bytes", totalBytesWritten, totalBytesExpectedToWrite);
             if(totalBytesWritten >= totalBytesExpectedToWrite)
             {
                 progressView.hidden = YES;
             }
         }];
     [operation start];
 }

这原来是 AFNetworking 的一个已知（但现在已修复）错误。
