AFNetworking POST request and identifying exact Issue in webservice

Question

I'm using AFNetworking and find no way to get correct response, searched ways but closely able to get the below code but still getting error

Also i have another issue. Is there any way to find correct issue in web services? So far i am finding it very difficult to troubleshoot the mistake.

because server always return error code, i need some debugging tool which can able to tell like you have not placed header or incorrect content type, invalid format....

It just returns error code and that means a lot more....

NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:@"http://www.somewebsiteurl/webservice/getResponse"]];
[request setHTTPMethod:@"POST"];

//set headers
NSString *contentType = [NSString stringWithFormat:@"text/html"];
[request addValue:contentType forHTTPHeaderField: @"Content-Type"];


//create the body
NSMutableData *postBody = [NSMutableData data];

[postBody appendData:[[NSString stringWithFormat:@"data={\"request\":{\"type\":\"getwork\"}}"] dataUsingEncoding:NSUTF8StringEncoding]];


//post
[request setHTTPBody:postBody];

//Response

{"response":{"message":"Invalid Request"}}

when i place this in http://apikitchen.com/ my webservice works

please visit AFNetworking github page github link to know about AFNetworking and here is the code given to send request using post in AFNetworking

Edit:

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSDictionary *parameters = @{@"request":@{@"type":@"getwork"}:@"data"};
[manager POST:@"http://www.somewebsiteurl/webservice/getResponse" parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"JSON: %@", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@", error);
}];

replace your parameters and send request

There are a few issues in how you setup the request.

But before anybody can answer this question, you need to specify what the server expects as a valid POST data. In your example, you are trying to pass a string:

data={"request":{"type":"getwork"}}

This string cannot be encoded to a parameter list required for an application/x-www-form-urlencoded MIME type. That, is AFNetworking - out of the box - cannot be used with this parameter string.

It's also not JSON. That is, AFNetworking with content type set to application/json can also not be used.

So, first define the syntax and the MIME type the server can accept.
