在Swift中使用Twilio發送短信

Question

我嘗試使用Twilio作為服務提供者，但他們沒有我理解的Swift的例子。

我的任務是使用Swil的Twilio API向一個號碼發送短信。

我有一個Twilio.com帳戶 - 那個正在運行。 但是我如何以簡單的方式在Swift代碼中執行此操作。

Twilio確實提供了一個庫 - 但這適用於C＃而不是Swift（並且使用橋接頭看起來太復雜了！）

這是C＃示例，我需要一個簡單的Swift示例。

// Download the twilio-csharp library from twilio.com/docs/csharp/install
using System;
using Twilio;
class Example 
{
  static void Main(string[] args) 
  {
    // Find your Account Sid and Auth Token at twilio.com/user/account
    string AccountSid = "AC5ef8732a3c49700934481addd5ce1659";
    string AuthToken = "{{ auth_token }}";
    var twilio = new TwilioRestClient(AccountSid, AuthToken);


    var message = twilio.SendMessage("+14158141829", "+15558675309", "Jenny please?! I love you <3", new string[] {"http://www.example.com/hearts.png"});

    Console.WriteLine(message.Sid);
  }
}

Twilio福音傳教士在這里。

要從Swift發送文本消息，您只需直接向Twilios REST API發出請求即可。 也就是說，我不建議從iOS應用程序（或任何其他客戶端應用程序）執行此操作，因為它要求您在應用程序中嵌入Twilio帳戶憑據，這很危險。 我建議從服務器端應用程序發送SMS。

如果您確實想從您的應用程序發送消息，我知道有幾個Swift庫可以簡化HTTP請求：

• Alamofire - 來自AFNetworking的創建者Mattt Thompson - 用於此處的示例： https ：//www.twilio.com/blog/2016/11/how-to-send-an-sms-from-ios-in-swift 。 HTML
• SwiftRequest - 來自Twilio的Ricky Robinett

要使用SwiftRequest發出請求，它看起來像這樣：

var swiftRequest = SwiftRequest();

var data = [
    "To" : "+15555555555",
    "From" : "+15555556666",
    "Body" : "Hello World"
];

swiftRequest.post("https://api.twilio.com/2010-04-01/Accounts/[YOUR_ACCOUNT_SID]/Messages", 
    auth: ["username" : "[YOUR_ACCOUNT_SID]", "password" : "YOUR_AUTH_TOKEN"]
    data: data, 
    callback: {err, response, body in
        if err == nil {
            println("Success: \(response)")
        } else {
            println("Error: \(err)")
        }
});

希望有所幫助。

最近我經歷了Twilio文檔和很少的SO帖子。

您可以使用Swift 2.0中的以下代碼片段發送短信

func sendSMS()
    {

        let twilioSID = "your Sender ID here"
        let twilioSecret = "your token id here"

        //Note replace + = %2B , for To and From phone number
        let fromNumber = "%2B14806794445"// actual number is +14803606445
        let toNumber = "%2B919152346132"// actual number is +919152346132
        let message = "Your verification code is 2212 for signup with <app name here> "

        // Build the request
        let request = NSMutableURLRequest(URL: NSURL(string:"https://\(twilioSID):\(twilioSecret)@api.twilio.com/2010-04-01/Accounts/\(twilioSID)/SMS/Messages")!)
        request.HTTPMethod = "POST"
        request.HTTPBody = "From=\(fromNumber)&To=\(toNumber)&Body=\(message)".dataUsingEncoding(NSUTF8StringEncoding)

        // Build the completion block and send the request
        NSURLSession.sharedSession().dataTaskWithRequest(request, completionHandler: { (data, response, error) in
            print("Finished")
            if let data = data, responseDetails = NSString(data: data, encoding: NSUTF8StringEncoding) {
                // Success
                print("Response: \(responseDetails)")
            } else {
                // Failure
                print("Error: \(error)")
            }
        }).resume()
}

如果一切順利..你應該收到這樣的消息..

這是無密碼身份驗證的新Swift示例。 有關完整教程，請單擊此處

let url = "http://localhost:8000"
  var swiftRequest = SwiftRequest()
  var params:[String:String] = [
    "token" : token!.text
  ]

  swiftRequest.post(url + "/user/auth/", data: params, callback: {err, response, body in
    if( err == nil && response!.statusCode == 200) {
      if((body as NSDictionary)["success"] as Int == 1) {
        self.showAlert("User successfully authenticated!");
      } else {
        self.showAlert("That token isn't valid");
      }
    } else {
      self.showAlert("We're sorry, something went wrong");
    }
  })

    var swiftRequest = SwiftRequest();

Swift 3版本：

func sendSMS()
{
    print("Starting...")
    let twilioSID = "ENRET YOUR SID"
    let twilioSecret = "YOUR TOKEN"
    //Note replace + = %2B , for To and From phone number
    let fromNumber = "%29999999"// actual number is +9999999
    let toNumber = "%29999999"// actual number is +9999999
    let message = "Your verification code is 2212 for signup with"

    // Build the request
    let request = NSMutableURLRequest(url: URL(string:"https://\(twilioSID):\(twilioSecret)@api.twilio.com/2010-04-01/Accounts/\(twilioSID)/SMS/Messages")!)
    request.httpMethod = "POST"
    request.httpBody = "From=\(fromNumber)&To=\(toNumber)&Body=\(message)".data(using: .utf8)

    // Build the completion block and send the request
    URLSession.shared.dataTask(with: request as URLRequest, completionHandler: { (data, response, error) in
        print("Finished")
        if let data = data, let responseDetails = NSString(data: data, encoding: String.Encoding.utf8.rawValue) {
            // Success
            print("Response: \(responseDetails)")
        } else {
            // Failure
            print("Error: \(error)")
        }
    }).resume()
}
