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.
