Post Request with AFHttpRequestOperationManager no

问题:

I am using AFHTTPRequestOperationManager to post some JSON to my server, my code is below.

NSDictionary *parameters = [[NSDictionary alloc] initWithObjectsAndKeys:@"john", @"name", @"[e-mail]", @"email", @"xxxx", @"password", @"1", @"type", nil];
// Do any additional setup after loading the view.
AFSecurityPolicy *policy = [[AFSecurityPolicy alloc] init];
[policy setAllowInvalidCertificates:YES];
AFHTTPRequestOperationManager *operationManager = [AFHTTPRequestOperationManager manager];
[operationManager setSecurityPolicy:policy];

[operationManager POST:@"posturl here" parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"JSON: %@", [responseObject description]);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@", [error description]);
}];

and the response is as follows:

2013-11-18 16:49:29.780 SwapOnceApiTester[12651:60b] Error: Error Domain=AFNetworkingErrorDomain Code=-1011 "Request failed: unsupported media type (415), got 1664256" UserInfo=0x1565a6c0 {NSErrorFailingURLKey=xxxxxxx, AFNetworkingOperationFailingURLResponseErrorKey=<NSHTTPURLResponse: 0x15656db0> { URL: xxxxxxxxx } { status code: 415, headers {
    "Cache-Control" = "max-age=604800";
    Connection = "keep-alive";
    "Content-Type" = "application/json";
    Date = "Mon, 18 Nov 2013 11:49:28 GMT";
    Expires = "Mon, 25 Nov 2013 11:49:28 GMT";
    Server = nginx;
    "Transfer-Encoding" = Identity;
    "X-Powered-By" = PleskLin;
} }, NSLocalizedDescription=Request failed: unsupported media type (415), got 1664256}

I dont know what the problem is with this.

You need to set your request and response serializers to handle JSON using AFJSONRequestSerializer and AFJSONResponseSerializer before executing your request. Using an NSDictionary literal for your parameters helps code clarity as well:

AFSecurityPolicy *policy = [[AFSecurityPolicy alloc] init];
[policy setAllowInvalidCertificates:YES];

AFHTTPRequestOperationManager *operationManager = [AFHTTPRequestOperationManager manager];
[operationManager setSecurityPolicy:policy];
operationManager.requestSerializer = [AFJSONRequestSerializer serializer];
operationManager.responseSerializer = [AFJSONResponseSerializer serializer];

[operationManager POST:@"posturl here" 
            parameters: @{@"name":  @"john",
                        @"email":   @"[e-mail]",
                        @"password: @"xxxxx",
                        @"type":    @"1"}
               success:^(AFHTTPRequestOperation *operation, id responseObject) {
                   NSLog(@"JSON: %@", [responseObject description]);
               } 
               failure:^(AFHTTPRequestOperation *operation, NSError *error) {
                   NSLog(@"Error: %@", [error description]);
               }
];

Just solve my problem, my server was not configured to accept the charset utf8 with application/json so i just removed the charset utf for ajson serializer in Afnetworking 2.0 and now it is working correclty.
