# Alamofire

# Manual Validation

Alamofire.request(.GET, "https://httpbin.org/get", parameters: ["foo": "bar"])
     .validate(statusCode: 200..<300)
     .validate(contentType: ["application/json"])
     .response { response in
         print(response)
     }

# Automatic Validation

Alamofire.request("https://httpbin.org/get").validate().responseJSON { response in
switch response.result {
case .success:
    print("Validation Successful")
case .failure(let error):
    print(error)
 }
}

# Chained Response Handlers

Alamofire.request(.GET, "https://httpbin.org/get")
     .validate()
     .responseString { response in
         print("Response String: \(response.result.value)")
     }
     .responseJSON { response in
         print("Response JSON: \(response.result.value)")
     }

         print(response.data)     // server data
         print(response.result)   // result of response serialization
