Swift中使用POST方法的Swift中的HTTP请求

Question

我试图在Swift3中运行HTTP请求，将POST 2参数发送到URL。

例子：

链接：

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

PARAMS：

{ 
    "user_id":"chaitanya3191@gmail.com", 
    "password":"123" 
} 

什么是做到这一点的最简单的方法？

我甚至不想阅读回复。我只是想通过一个PHP文件来发送数据库上的更改。

我猜，你是完全的新手，但这里的东西，你可以在SWIFT 3尝试：

1. 打开的info.plist文件（双击或右键单击>打开为>源代码

   <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> 
   

   ：）

2. 关闭</dict>和</plist>标签在此之前的代码粘贴

3. 现在打开你的视图控制器并粘贴此代码在那里你想POST请求：

   var request = URLRequest(url: URL(string: "http://test.tranzporthub.com/street45/customer_login.php")!) 
   request.httpMethod = "POST" 
   let postString = "user_id=chaitanya3191@gmail.com&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() 
   

注意：您可以删除打印语句如果你不需要！

希望这会有所帮助！ :)

@IBAction func postAction(_ sender: Any) { 
    let Url = String(format: "your url") 
    guard let serviceUrl = URL(string: Url) else { return } 
    //  let loginParams = String(format: LOGIN_PARAMETERS1, "test", "Hi World") 
    let parameterDictionary = ["username" : "@kilo_laco", "tweet" : "Hi World"] 
    var request = URLRequest(url: serviceUrl) 
    request.httpMethod = "POST" 
    request.setValue("Application/json", forHTTPHeaderField: "Content-Type") 
    guard let httpBody = try? JSONSerialization.data(withJSONObject: parameterDictionary, options: []) else { 
     return 
    } 
    request.httpBody = httpBody 

    let session = URLSession.shared 
    session.dataTask(with: request) { (data, response, error) in 
     if let response = response { 
      print(response) 
     } 
     if let data = data { 
      do { 
       let json = try JSONSerialization.jsonObject(with: data, options: []) 
       print(json) 
      }catch { 
       print(error) 
      } 
     } 
     }.resume()
