POST request not working while using Alamofire pod in swift2?

Question

I’m doing a Demo App in Swift 2 that makes an HTTP POST request. But don’t understand why my request doesn't hit the server. I’m using Alamofire 3.0, Xcode 7.2, swift 2.0. I installed the Alamofire pod based on this link: https://github.com/Alamofire/Alamofire#requirements

And my string is

str = "{videos{title,videourl,imageurl}}"

Here my code is:

Alamofire.request(
    .POST,
    url,
    parameters: Dictionary(),
    encoding: .Custom({
        (convertible, params) in
        let mutableRequest = convertible.URLRequest.copy() as! NSMutableURLRequest
        mutableRequest.setValue("application/graphql", forHTTPHeaderField: "Content-Type")
        mutableRequest.HTTPBody = str.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)
        return (mutableRequest, nil)
    }),
    headers: nil
).responseJSON{
    (JSON) -> Void in
        if  JSON.result.value != nil
        {
            print(JSON.result.value)
            self.delegate.successReponse(JSON.result.value!, withType: type)      
        } 
        else
        {   
        }
}

When i’m printing the JSON.result.value, it’s showing like this:

Optional({
    errors = (
        {
        }
    );
})

I don’t understand why it is not reaching to the server.

May be the server is not returning any data? You should print the http response of the request made in the console and check — Penkey Suresh, Dec 29 '15 at 09:47
You say "it doesn't hit the server", did you actually check server logs? Is your URL correct? — jcaron, Dec 29 '15 at 10:01
@jcaron yes i check the server logs and also my url works fine in postman. — Ramakrishna, Dec 29 '15 at 13:22

Have your do it before ? App Transport Security in info.plist. https://github.com/Alamofire/Alamofire Secondly, the parameters 's don't have any things. It should be change your string to Dictionary.

Your can use json to make string to Dictionary.

let data = changestring.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: true)
var dict = NSDictionary()
do{
    //dict = try NSJSONSerialization.JSONObjectWithData(data!, options: .MutableContainers) as! NSDictionary
    dict = try NSJSONSerialization.JSONObjectWithData(data!, options: []) as! NSDictionary
}
catch{
}

NSLog("this is dict \(dict)")

Or you can just past NSDictionary to parameters.

Alamofire.request(.POST, "https://httpbin.org/post", parameters: parameters, encoding: .JSON)

If your want to others method for HTTP POST and GET, this link is Suitable for you: https://github.com/RYANCOAL/swift-with-AFNetworking/blob/master/TestHTTPTests/TestHTTPTests.swift

Manual Validation Alamofire.validate(contentType: ["application/json"]) can search the value for contentType, by I don't know it can / cannot be set contentType.
