Hi every one ,
i am trying to upload a video file using afnetworking 2.x
it shows an error like "'request body stream exhausted'" after searching a lot in web i got answer like 'upload again when you got this error' after uploading the second time it works , But uploading second time is not good

here is my code

-(void)uploadVideo
{

NSURLCredential nsCredential = [NSURLCredential credentialWithUser:@"*********_" password:@"_*********************" persistence:NSURLCredentialPersistenceForSession];

//    NSURLCredential *nsCredential = [NSURLCredential credentialWithUser:@"*********************" password:@"********************" persistence:NSURLCredentialPersistenceForSession];
//[client setDefaultCredential:nsCredential];
//[manager setCredential:nsCredential];

NSMutableDictionary *params = [[NSMutableDictionary alloc] initWithObjectsAndKeys:@"*****", @"userid", nil];
[params setObject:@"************" forKey:@"accesstoken"];


NSString *url = [ NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"Apple2" ofType:@".mp4"]];

NSData *videoData = [NSData dataWithContentsOfFile:url];

AFHTTPRequestSerializer *serializer = [AFHTTPRequestSerializer serializer];



NSMutableURLRequest *request =
[serializer multipartFormRequestWithMethod:@"POST" URLString:@"http://something.com/ios/upload/video"
                                parameters:params
                 constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
                     [formData appendPartWithFileData:videoData
                                                 name:@"file"
                                             fileName:@"Apple2.mp4"
                                             mimeType:@"video/mp4"];

                     [formData throttleBandwidthWithPacketSize:kAFUploadStream3GSuggestedPacketSize delay:kAFUploadStream3GSuggestedDelay];
                 }];


AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager setCredential:nsCredential];
AFHTTPRequestOperation *operation =
[manager HTTPRequestOperationWithRequest:request
                                 success:^(AFHTTPRequestOperation *operation, id responseObject) {
                                     NSLog(@"Success %@", responseObject);
                                 } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
                                     NSLog(@"Failure %@", error.description);
                                     [self uploadVideo];
                                 }];


[operation setUploadProgressBlock:^(NSUInteger __unused bytesWritten,
                                    long long totalBytesWritten,
                                    long long totalBytesExpectedToWrite) {
    NSLog(@"Wrote %lld/%lld", totalBytesWritten, totalBytesExpectedToWrite);
}];


[operation start];
Can you fix this error

Thank you

I'm currently investigating similar behavior but only when I receive an authentication challenge. Here's a POST, with 'app.server' being a subclass of AFHTTPRequestOperationManager (2.0.1)

    CURAppDelegate *app = [[UIApplication sharedApplication] delegate];
    NSString *stringURL = @"http://example.com/myurlisactuallyhere";

    [app.server POST:stringURL parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData){
        [formData appendPartWithFileData:self.mediaData name:@"image_submission" fileName:@"iOS_image" mimeType:@"image/jpeg"];
        [formData throttleBandwidthWithPacketSize:kAFUploadStream3GSuggestedPacketSize delay:kAFUploadStream3GSuggestedDelay];
    } success:^(AFHTTPRequestOperation *operation, id responseObject){
        callback();
    } failure:^(AFHTTPRequestOperation *operation, NSError *error){
        errorCallback(@"Image failed to upload");
    }];
I hit the authentication challenge, and then if I add this nsurlconnectiondatadelegate method into AFHttpRequestOperation it gets tripped

- (NSInputStream *)connection:(NSURLConnection *)connection needNewBodyStream:(NSURLRequest *)request
{
    DebugLog(@"need new stream");
    return nil;
}
Have to go for the new years... but I will keep digging and looking at older issues

In its current implementation, AFStreamingMultipartFormData cannot be copied and re-opened in the way that needNewBodyStream: mandates. Retuning nil in this method triggers automatic buffer rewind behavior that only takes effect with non-stream request bodies, which makes it a strong default.

Retrying the request is the recommended solution. A future version of AFNetworking may address this issue more directly.
