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!

Solution 1

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.

Solution 2

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];

Solution 3

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];

Solution 4

 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];

@ChitraKhatri It's an AFHTTPClient instance (from AFNetworking 1, it no longer exists in AFNetworking 2)

For AFNetworking 2, you can use the following solution as a reference: stackoverflow.com/a/20812002/1048331
