How to log HTTP POST Request

Question

I am new to Alamofire and Swift, so please bear with me. I am trying to upload a Product JSON to server using Alamofire. However I keep getting a status code : 400 failure. Is there any way to log the request being sent to the server so that I can check if my data format is proper. I have provided the code for upload below.

    static func uploadProduct(productJSON: [String : AnyObject]) {
    Alamofire.request(.POST, ServerConfig.ADD_PRODUCT_URL, parameters: productJSON, encoding: .JSON, headers: nil)
        .responseJSON(completionHandler: { responseRequest, responseResponse, responseResult in
            print(responseRequest!.URL)
            print(responseResponse)
            print(responseResult)
    })
}

This is the error that I get.

sellers.strawmine.com/api/v1/products/add } { status code: 400, headers {
Connection = "keep-alive";
Date = "Tue, 06 Oct 2015 10:53:44 GMT";
Server = "nginx/1.4.6 (Ubuntu)";
"Transfer-Encoding" = Identity;
} })
FAILURE

Please help. I have spent a good amount of time on this. Thanks in advance!

just a sidenote, why don't u use the native task that comes with iOS. it is really powerful. — William Kinaan, Oct 06 '15 at 11:09
please check for example [this question](http://stackoverflow.com/questions/32953501/cannot-convert-jsonarray-element-to-integer/32954028#32954028) about sending a post request and parse the response json.

HTTP 400 = "Bad Request". Your `productJSON` parameters are likely to be wrong. — Eric Aya, Oct 06 '15 at 11:20
Also check NSAppTransportSecurity if you are using HTTP, and not HTTPS http://stackoverflow.com/questions/31216758/how-can-i-add-nsapptransportsecurity-to-my-info-plist-file — KrisJones, Oct 06 '15 at 12:28

You are getting http error 400 : http://www.checkupdown.com/status/E400.html

Or simply, bad request.

I think you should check if your endpoint is correct, and if your server has configured route for that action. Not sure what your backend is.

You should leverage the cURL support built into the Request object by conforming to the CustomDebugStringConvertible protocol.

let request = Alamofire.request(.POST, ServerConfig.ADD_PRODUCT_URL, parameters: productJSON, encoding: .JSON)
request.responseJSON { request, response, result in
        print(request!.URL)
        print(response)
        print(result)
    }

debugPrint(request)
