AFNetworking upload progress sending SOAP NSData - objective-c

Question

I am using AFNetworking and would like to upload an NSData object to my server. I am trying to upload to our SOAP server, so I have XML that I have converted to an NSData object. For some reason, the follow does NOT work:
// Back to NSData
NSData *convertedFile = [xml dataUsingEncoding:NSUTF8StringEncoding];
NSURL *url = [NSURL URLWithString:siteConfiguration.soapURL];
AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:url];
NSMutableURLRequest *request = [httpClient multipartFormRequestWithMethod:#"POST" path:#"" parameters:nil constructingBodyWithBlock: ^(id <AFMultipartFormData>formData) {
[formData appendPartWithFormData:convertedFile name:assetCreation.name];
}];
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
[operation setUploadProgressBlock:^(NSUInteger bytesWritten, long long totalBytesWritten, long long totalBytesExpectedToWrite) {
// Progress
float totalProgress = (float)totalBytesWritten/(float)totalBytesExpectedToWrite;
progress(totalProgress, totalBytesWritten, totalBytesExpectedToWrite);
if (totalBytesExpectedToWrite == totalBytesWritten) {
completion();
}
}];
[operation start];
But when not using the multipartFormRequestWithMethod block, it DOES work and the file is correctly uploaded, but there is NO progress shown, as the callback is only called once:
// Back to NSData
NSData *convertedFile = [xml dataUsingEncoding:NSUTF8StringEncoding];
NSURL *url = [NSURL URLWithString:siteConfiguration.soapURL];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];
[request setHTTPMethod: #"POST"];
[request setHTTPBody:convertedFile];
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
[operation setUploadProgressBlock:^(NSUInteger bytesWritten, long long totalBytesWritten, long long totalBytesExpectedToWrite) {
// Progress
float totalProgress = (float)totalBytesWritten/(float)totalBytesExpectedToWrite;
progress(totalProgress, totalBytesWritten, totalBytesExpectedToWrite);
if (totalBytesExpectedToWrite == totalBytesWritten) {
MatrixAsset *asset = [[MatrixAsset alloc] init];
completion(asset);
}
}];
[operation start];
It seems that my server really wants to be sent the HTTPBody with my NSData object. Is it possible to do the same with the AFNetworking progress callback?

Ok, I got it working. Looks like I was going about it wrong:
// Setup the connection
NSString *wsdlURL = [NSString stringWithFormat:#"%#?WSDL", siteConfiguration.soapURL];
NSURL *serviceUrl = [NSURL URLWithString:wsdlURL];
NSMutableURLRequest *serviceRequest = [NSMutableURLRequest requestWithURL:serviceUrl];
[serviceRequest setValue:#"text/xml" forHTTPHeaderField:#"Content-type"];
[serviceRequest setHTTPMethod:#"POST"];
[serviceRequest setHTTPBody:[xml dataUsingEncoding:NSUTF8StringEncoding]];
// Operation
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:serviceRequest];
[operation setUploadProgressBlock:^(NSUInteger bytesWritten, long long totalBytesWritten, long long totalBytesExpectedToWrite) {
// Progress
float totalProgress = (float)totalBytesWritten/(float)totalBytesExpectedToWrite;
progress(totalProgress, totalBytesWritten, totalBytesExpectedToWrite);
}];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"Success");
MatrixAsset *asset = [[MatrixAsset alloc] init];
completion(asset);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"error: %#", error.localizedDescription);
NSLog(#"error: %#", error.localizedFailureReason);
}];
[operation start];

You need SOAPAction to continue:
[serviceRequest setValue:#"SOAP_ACTION_URL" forHTTPHeaderField:#"SOAPAction"];
