How to set the HTTP body for a request using AFNetworking?

Question

In the early versions of AFNetworking if I had to make my own custom client then I would simply inherit from AFHTTPClient and create my methods. In AFNetworking 2.0 I believe I need to inherit from AFHTTPSessionManager.

@interface MyCustomClient : AFHTTPSessionManager
    {

    }

In my situation I need to send in request as soap. This means that HTTP Body will be soap and HTTP HEADERS will be text/xml.

Let's say I have a variable which contains the entire soap body I need to send to the server.

NSString *soapBody = @"Soap body";

Using my custom class defined above which inherits from AFHTTPSessionManager how will I set the soap body to the Request HTTPBody.

If there is anyway to access NSURLRequest from inside the AFHTTPSessionManager then I can simply do setHTTPBody but it seems there is not?

I hope I am making sense now!

You should create a subclass of AFHTTPRequestSerializer, then implement the protocol AFURLRequestSerialization, this class is going to care about adding the body and headers to the request

 - (NSURLRequest *)requestBySerializingRequest:(NSURLRequest *)request
                                withParameters:(id)parameters
                                         error:(NSError * __autoreleasing *)error
{
     NSParameterAssert(request);

     if ([self.HTTPMethodsEncodingParametersInURI containsObject:[[request HTTPMethod] uppercaseString]]) {
         return [super requestBySerializingRequest:request withParameters:parameters error:error];
     }

     NSMutableURLRequest *mutableRequest = [request mutableCopy];

     [self.HTTPRequestHeaders enumerateKeysAndObjectsUsingBlock:^(id field, id value, BOOL * __unused stop) {
         if (![request valueForHTTPHeaderField:field]) {
             [mutableRequest setValue:value forHTTPHeaderField:field];
         }
     }];


     [mutableRequest setValue:@"application/soap+xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
     [mutableRequest setHTTPBody:@"This is the soap Body!!"];

     return mutableRequest;
}

You can read the implementation or other AFHTTPRequestSerializer subclasses https://github.com/AFNetworking/AFNetworking/blob/master/AFNetworking/AFURLRequestSerialization.m#L1094

Answer 2

Init a NSMutableURLRequest *request; and set httpBody to request by: [request setHTTPBody:[soapMessage dataUsingEncoding:NSUTF8StringEncoding]];

You can try this code.

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:requestURL]];
    request.HTTPMethod = @"POST";
    [request setValue:@"application/soap+xml;charset = utf-8" forHTTPHeaderField:@"Content-Type"];
    request.HTTPBody = [soapMessage dataUsingEncoding:NSUTF8StringEncoding];
    NSURLSession *session = [NSURLSession sessionWithConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration] delegate:self delegateQueue:nil];
    NSURLSessionDataTask *sessionTask = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
              if (!error) {
                  // parse response here
              } else {
                  // error
              }
          }];
    [sessionTask resume];

hope it help You.
