PUT request with data using AFNetworking 2.0 - ios

Question

I want to upload video using PUT request and this is my experience.
I was trying many possibilities of doing PUT request using AFNetworking 2.0, but everything fails.
But I resolved this and this "Question" is information for everybody else who is asking solution.
This works for me:
NSDictionary *headersDict = #{#"Content-Length": [NSString stringWithFormat:#"%#", mySize], #"Content-Type": #"video/mp4", #"Accept": #"application/json", #"Authorization": [NSString stringWithFormat:#"Basic %#", hash]};
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:urlToPut];
[request setHTTPMethod:#"PUT"];
[request setHTTPBody:videoData];
[request setAllHTTPHeaderFields:headersDict];
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
// if everything run great, we have to invalidate timer to notify
[uploadTimer invalidate];
}
failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"error: %#", error);
}];
// start timer where app will be checking upload progres on the server
uploadTimer = [NSTimer scheduledTimerWithTimeInterval:.1
target:self
selector:#selector(checkUploadProgressForRecord:)
userInfo:record
repeats:YES];
[operation start];
Anybody has another solution?

Answer 1

You approach has the following issues:
The PUT method is not the suggested method for uploading a file. PUT can be used, but this requires that the server MUST create the resource at the specified URI. In most cases however, the server will create a new URI (which is unknown to the client) when saving the uploaded file locally on the server. In this case, a POST method must be used.
You are using a NSData object which represents the content of the file and assign it the request with setHTTPBody. This is problematic regarding system memory when the file is large and the NSData object uses a heap allocated buffer to hold the file's content. You should either use a NSData object which uses a memory mapped file or a NSStream to represent the file content.
You are too vague about the request headers:
`[request setAllHTTPHeaderFields:headersDict];`
Request header are important. You should set the Content-Type and possible the Content-Length header.
