HTTP Request in Swift with POST method in swift3

Question

I'm trying to run a HTTP Request in Swift3, to POST 2 parameters to a URL.

Example:

Link:

http://test.tranzporthub.com/street45/customer_login.php

Params:

{
    "user_id":"[email protected]",
    "password":"123"
}

What is the simplest way to do that?

I don't even want to read the response. I just want to send that to perform changes on my database through a PHP file.

Answer 1

I guess, you are totally newbie but here is something that you can try in SWIFT 3:

1. Open info.plist file (Double Click OR Right Click > Open As > Source Code)

2. Paste this code before closing </dict> and </plist> tags:

   <key>NSAppTransportSecurity</key>
   <dict>
   <key>NSExceptionDomains</key>
   <dict>
       <key>tranzporthub.com</key>
       <dict>
           <!--Include to allow subdomains-->
           <key>NSIncludesSubdomains</key>
           <true/>
           <!--Include to allow HTTP requests-->
           <key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key>
           <true/>
           <!--Include to specify minimum TLS version-->
           <key>NSTemporaryExceptionMinimumTLSVersion</key>
           <string>TLSv1.1</string>
       </dict>
   </dict>
   

3. Now Open your view Controller and paste this code where you want to make post request:

   var request = URLRequest(url: URL(string: "http://test.tranzporthub.com/street45/customer_login.php")!)
   request.httpMethod = "POST"
   let postString = "[email protected]&password=123"
   request.httpBody = postString.data(using: .utf8)
   let task = URLSession.shared.dataTask(with: request) { data, response, error in
       guard let data = data, error == nil else {                                                 // check for fundamental networking error
           print("error=\(error)")
           return
       }
   
       if let httpStatus = response as? HTTPURLResponse, httpStatus.statusCode != 200 {           // check for http errors
           print("statusCode should be 200, but is \(httpStatus.statusCode)")
           print("response = \(response)")
   
       }
   
       let responseString = String(data: data, encoding: .utf8)
       print("responseString = \(responseString)")
   }
   task.resume()
   

NOTE: You can remove print statements if you don't need!

Hope this helps! :)
