AFNetworking - How can I PUT and POST raw data without using a key value pair?

Question

I am trying to make an HTTP PUT request using AFNetworking to create an attachment in a CouchDB server. The server expects a base64 encoded string in the HTTP body. How can I make this request without sending the HTTP body as a key/value pair using AFNetworking?

I began by looking at this method:

- (void)putPath:(NSString *)path
 parameters:(NSDictionary *)parameters
    success:(void (^)(AFHTTPRequestOperation *operation, id responseObject))success
    failure:(void (^)(AFHTTPRequestOperation *operation, NSError *error))failure;

But here the parameters are to be of type: NSDictionary. I just want to send a base64 encoded string in the HTTP body but not associated with a key. Can someone point me to the appropriate method to use? Thanks!

Hejazi's answer is simple and should work great.

If, for some reason, you need to be very specific for one request - for example, if you need to override headers, etc. - you can also consider building your own NSURLRequest.

Here's some (untested) sample code:

// Make a request...
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:myURL];

// Generate an NSData from your NSString (see below for link to more info)
NSData *postBody = [NSData base64DataFromString:yourBase64EncodedString];

// Add Content-Length header if your server needs it
unsigned long long postLength = postBody.length;
NSString *contentLength = [NSString stringWithFormat:@"%llu", postLength];
[request addValue:contentLength forHTTPHeaderField:@"Content-Length"];

// This should all look familiar...
[request setHTTPMethod:@"POST"];
[request setHTTPBody:postBody];

AFHTTPRequestOperation *operation = [client HTTPRequestOperationWithRequest:request success:success failure:failure];
[client enqueueHTTPRequestOperation:operation];

The NSData category method base64DataFromString is available here.

@ChitraKhatri It's an `AFHTTPClient` instance (from AFNetworking 1, it no longer exists in AFNetworking 2) — Aaron Brager, Jun 04 '14 at 16:26
For AFNetworking 2, you can use the following solution as a reference: http://stackoverflow.com/a/20812002/1048331 — Myxtic, Jul 23 '14 at 19:38

You can use multipartFormRequestWithMethod method as following:

NSURLRequest *request = [self multipartFormRequestWithMethod:@"PUT" path:path parameters:parameters constructingBodyWithBlock:^(id <AFMultipartFormData> formData) {
    [formData appendString:<yourBase64EncodedString>]
}];
AFHTTPRequestOperation *operation = [client HTTPRequestOperationWithRequest:request success:success failure:failure];
[client enqueueHTTPRequestOperation:operation];

Here you have an example sending a raw json:

NSDictionary *dict = ...
NSError *error;
NSData *dataFromDict = [NSJSONSerialization dataWithJSONObject:dict
                                                           options:NSJSONWritingPrettyPrinted
                                                             error:&error];

AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];

NSMutableURLRequest *req = [[AFJSONRequestSerializer serializer] requestWithMethod:@"POST" URLString:YOUR_URL parameters:nil error:nil];

req.timeoutInterval = 30;
[req setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[req setValue:@"application/json" forHTTPHeaderField:@"Accept"];
[req setValue:IF_NEEDED forHTTPHeaderField:@"Authorization"];

[req setHTTPBody:dataFromDict];

[[manager dataTaskWithRequest:req completionHandler:^(NSURLResponse * _Nonnull response, id  _Nullable responseObject, NSError * _Nullable error) {
    if (!error) {
        NSLog(@"%@", responseObject);
    } else {
        NSLog(@"Error: %@, %@, %@", error, response, responseObject);
    }
}] resume];

 NSData *data = someData;
 NSMutableURLRequest *requeust = [NSMutableURLRequest requestWithURL:          
 [NSURL URLWithString:[self getURLWith:urlService]]];

[reqeust setHTTPMethod:@"PUT"];
[reqeust setHTTPBody:data];
[reqeust setValue:@"application/raw" forHTTPHeaderField:@"Content-Type"];

NSURLSessionDataTask *task = [manager uploadTaskWithRequest:requeust fromData:nil progress:^(NSProgress * _Nonnull uploadProgress) {

} completionHandler:^(NSURLResponse * _Nonnull response, id  _Nullable responseObject, NSError * _Nullable error) {

}];
[task resume];

I'm using AFNetworking 2.5.3 and create new POST method for AFHTTPRequestOperationManager.

extension AFHTTPRequestOperationManager {

    func POST(URLString: String!, rawBody: NSData!, success: ((AFHTTPRequestOperation!, AnyObject!) -> Void)!, failure: ((AFHTTPRequestOperation!, NSError!) -> Void)!) {

        let request = NSMutableURLRequest(URL: NSURL(string: URLString, relativeToURL: baseURL)!)
        request.HTTPMethod = "POST"
        request.HTTPBody = rawBody

        let operation = HTTPRequestOperationWithRequest(request, success: success, failure: failure)

        operationQueue.addOperation(operation)
    }

}

Please use below method.

+(void)callPostWithRawData:(NSDictionary *)dict withURL:(NSString 
*)strUrl withToken:(NSString *)strToken withBlock:(dictionary)block
{
NSError *error;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:dict options:0 error:&error];
NSString *jsonString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
Please use below method.
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
NSMutableURLRequest *req = [[AFJSONRequestSerializer serializer] requestWithMethod:@"POST" URLString:[NSString stringWithFormat:@"%@/%@",WebserviceUrl,strUrl] parameters:nil error:nil];

req.timeoutInterval= [[[NSUserDefaults standardUserDefaults] valueForKey:@"timeoutInterval"] longValue];
[req setValue:strToken forHTTPHeaderField:@"Authorization"];
[req setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[req setValue:@"application/json" forHTTPHeaderField:@"Accept"];
[req setHTTPBody:[jsonString dataUsingEncoding:NSUTF8StringEncoding]];

[[manager dataTaskWithRequest:req completionHandler:^(NSURLResponse * _Nonnull response, id  _Nullable responseObject, NSError * _Nullable error) {
    if (!error) {
        if ([responseObject isKindOfClass:[NSData class]]) {
            NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *) response;
            if ((long)[httpResponse statusCode]==201) {
                NSMutableDictionary *dict = [[NSMutableDictionary alloc] init];
                [dict setObject:@"201" forKey:@"Code"];

                if ([httpResponse respondsToSelector:@selector(allHeaderFields)]) {
                    NSDictionary *dictionary = [httpResponse allHeaderFields];
                    NSLog(@"%@",[dictionary objectForKey:@"Location"]);
                     [dict setObject:[NSString stringWithFormat:@"%@",[dictionary objectForKey:@"Location"]] forKey:@"Id"];
                     block(dict);
                }
            }
            else if ((long)[httpResponse statusCode]==200) {
                //Leave Hours Calculate
                NSDictionary *serializedData = [NSJSONSerialization JSONObjectWithData:responseObject options:kNilOptions error:nil];
                block(serializedData);
            }
            else{
            }
        }
        else if ([responseObject isKindOfClass:[NSDictionary class]]) {
            block(responseObject);
        }
    } else {
        NSMutableDictionary *dict = [[NSMutableDictionary alloc] init];
        [dict setObject:ServerResponceError forKey:@"error"];
        block(dict);
    }
}] resume];
}
