How to set HTTP request body using AFNetwork's AFHTTPRequestOperationManager?

Question

I am using AFHTTPRequestOperationManager (2.0 AFNetworking library) for a REST POST request. But the manager only have the call to set the parameters.

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

I need to set HTTP request body with a string as well. How can I do it using the AFHTTPRequestOperationManager? Thanks.

Answer 1

I had the same problem and solved it by adding code as shown below:

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:URL
              cachePolicy:NSURLRequestReloadIgnoringCacheData  timeoutInterval:10];

[request setHTTPMethod:@"POST"];
[request setValue:@"Basic: someValue" forHTTPHeaderField:@"Authorization"];
[request setValue: @"application/json" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody: [body dataUsingEncoding:NSUTF8StringEncoding]];

AFHTTPRequestOperation *op = [[AFHTTPRequestOperation alloc] initWithRequest:request];
op.responseSerializer = [AFJSONResponseSerializer serializer];
[op setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {

    NSLog(@"JSON responseObject: %@ ",responseObject);

} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@", [error localizedDescription]);

}];
[op start];

for AFHTTPRequestOperationManager

[requestOperationManager.requestSerializer setValue:@"your Content Type" forHTTPHeaderField:@"Content-Type"];
[requestOperationManager.requestSerializer setValue:@"no-cache" forHTTPHeaderField:@"Cache-Control"];

// Fill parameters
NSDictionary *parameters = @{@"name"        : @"John",
                             @"lastName"    : @"McClane"};

// Customizing serialization. Be careful, not work without parametersDictionary
[requestOperationManager.requestSerializer setQueryStringSerializationWithBlock:^NSString *(NSURLRequest *request, NSDictionary *parameters, NSError *__autoreleasing *error) {

    NSData *jsonData = [NSJSONSerialization dataWithJSONObject:parameters options:NSJSONWritingPrettyPrinted error:nil];
    NSString *argString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
    return argString;
}];

[requestOperationManager POST:urlString parameters:parameters timeoutInterval:kRequestTimeoutInterval success:^(AFHTTPRequestOperation *operation, id responseObject) {

    if (success)
        success(responseObject);

} failure:^(AFHTTPRequestOperation *operation, NSError *error) {

    if (failure)
        failure(error);
}];
