From the AFNetworking documentation I get the following code while trying to upload a file in a REST server which with other clients work fine but with my implementation it crashes with Internal Server Error.
The code is the following:
- (BOOL)uploadFile:(NSString *)path apiKey:(NSString *)apiKey
{
NSData *symbolsData = [NSData dataWithContentsOfFile:path];
if (!symbolsData) {
NSLog(@"Symbols file at %@ does not exist.", path);
return NO;
}
if ([symbolsData length] > 33554432) {
NSLog(@"Symbols file at %@ is too large to upload.", path);
return NO;
}
NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:[NSString stringWithFormat:@"%@/upload/thefile", BaseURL] parameters:nil constructingBodyWithBlock:
^(id<AFMultipartFormData> formData)
{
[formData appendPartWithFileData:symbolsData name:@"file" fileName:[path lastPathComponent] mimeType:@"application/zip"];
}
error:nil];
[request setValue:apiKey forHTTPHeaderField:@"X-theapikey"];
AFURLSessionManager* manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
NSURLSessionUploadTask* uploadTask = [manager uploadTaskWithStreamedRequest:request progress:nil completionHandler:
^(NSURLResponse *response, id responseObject, NSError *error)
{
if (!error)
{
NSLog(@"Successfully uploade file: %@\r\nwith Response: %@", [path lastPathComponent], (NSString*)responseObject);
}
else
{
NSLog(@"There was an error while uploading the file: %@", [error description]);
}
}];
[uploadTask resume];
return YES;
}
The error:
There was an error while uploading file: Error Domain=NSURLErrorDomain Code=-1001 "The request timed out." UserInfo=0x6000000e8700 {NSUnderlyingError=0x60000005c0e0 "The request timed out.", NSErrorFailingURLStringKey=http://IP_ADDRESS:3000/upload/thefile, NSErrorFailingURLKey=http://IP_ADDRESS:3000/upload/thefile, NSLocalizedDescription=The request timed out.}
After searchnig for this in the internet I've seen a lot of implementations, MIME type changed to application/octet-stream and other things but nothing worked.
Also added the AFNetworkActivityLogger and registered to the NSNotificationCenter to examine the request:
Request: <NSMutableURLRequest: 0x600000014680> { URL: http://IP_ADDRESS:3000/upload/thefile }
2014-05-28 03:03:16.112 MyMacApp[5092:303] POST 'http://IP_ADDRESS:3000/upload/thefile': {
"Accept-Language" = "en;q=1, ja;q=0.9, fr;q=0.8, de;q=0.7, es;q=0.6, it;q=0.5";
"Content-Length" = 817739;
"Content-Type" = "multipart/form-data; boundary=Boundary+E25BB25240379DA8";
"User-Agent" = "MyMacApp/1.1 (Mac OS X Version 10.9.3 (Build 13D65))";
"X-thapikey" = 9e301234;
} (null)
I can see the Content-Type looks good and there is a Content-Length.
EDIT: The server exception thrown:

Any ideas how to debug and find out why my request is failing?
The server accepts files and it is tested with other clients, POSTman, Cocoa REST Client.
Thanks.
