Sending JSON POST request in Swift3 - ios

Question

In my app i'm trying to make http post request with json data. The following json must be transferred to api
{
"Password":"123456",
"Email":"test#gmail.com"
}
Here is my code for this task
let dict = ["Email": "test#gmail.com", "Password":"123456"] as [String: Any]
if let jsonData = try? JSONSerialization.data(withJSONObject: dict, options: []) {
let url = NSURL(string: "http://xxxxxxxxx.net/api/Login")!
let request = NSMutableURLRequest(url: url as URL)
request.httpMethod = "POST"
request.httpBody = jsonData
let task = URLSession.shared.dataTask(with: request as URLRequest){ data,response,error in
if error != nil{
print(error?.localizedDescription)
return
}
do {
let json = try JSONSerialization.jsonObject(with: data!, options: .mutableContainers) as? NSDictionary
if let parseJSON = json {
let resultValue:String = parseJSON["success"] as! String;
print("result: \(resultValue)")
print(parseJSON)
}
} catch let error as NSError {
print(error)
}
}
task.resume()
}
I'm getting the following error
Error Domain=NSCocoaErrorDomain Code=3840 "No value." UserInfo={NSDebugDescription=No value.}
The response data is empty. What I'm doing wrong, or i have missed something in my code?

Try two things:
First :
jsonData = try? JSONSerialization.data(withJSONObject: dict, options: .prettyPrinted)
then add logs if your data is converted into JSON. Convert your data into String and print the value.
Also add
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
before httpBody. Sometimes we have to tell server in our request that we are posting JSON data.
Hope this will help you!!
Happy Coding!
