解析Twilio statuscallback電話/會議活動

Question

我創建使用Twilio公司的Java lib中，像這樣的電話：

PhoneNumber phoneNumberTo = new PhoneNumber(to); 
PhoneNumber phoneNumberFrom = new PhoneNumber(from); 
com.twilio.rest.api.v2010.account.Call call = new CallCreator(phoneNumberTo, phoneNumberFrom, URI.create(twimlUrl)) 
    .setStatusCallback(URI.create(twStatusCallbackUrl)) 
    .setStatusCallbackEvent(Arrays.asList(
     com.twilio.rest.api.v2010.account.Call.Event.ANSWERED.toString(), 
     com.twilio.rest.api.v2010.account.Call.Event.COMPLETED.toString(), 
     com.twilio.rest.api.v2010.account.Call.Event.INITIATED.toString(), 
     com.twilio.rest.api.v2010.account.Call.Event.RINGING.toString())) 
    .create(this.client); 

我得到調用事件application/x-www-form-urlencoded。有沒有一種最佳實踐方式將發送的表單數據解析爲某種Twilio調用事件對象？通過Twilio發送的狀態

例子：

更新：由statusCallbacks例如返回的事件中維護狀態，是你必須建立到您的應用程序。

查看making a call and monitoring progress events文檔中給出的以下示例。

// Install the Java helper library from twilio.com/docs/java/install 
import com.twilio.sdk.TwilioRestClient; 
import com.twilio.sdk.TwilioRestException; 
import com.twilio.sdk.resource.factory.CallFactory; 
import com.twilio.sdk.resource.instance.Call; 
import com.twilio.sdk.resource.list.CallList; 
import java.util.ArrayList; 
import java.util.List; 
import org.apache.http.NameValuePair; 
import org.apache.http.message.BasicNameValuePair; 

public class Example { 

    // Find your Account Sid and Token at twilio.com/user/account 
    public static final String ACCOUNT_SID = "ACXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"; 
    public static final String AUTH_TOKEN = "your_auth_token"; 

    public static void main(String[] args) throws TwilioRestException { 
    TwilioRestClient client = new TwilioRestClient(ACCOUNT_SID, AUTH_TOKEN); 

    // Build a filter for the CallList 
    List<NameValuePair> params = new ArrayList<NameValuePair>(); 
    params.add(new BasicNameValuePair("Url", "http://demo.twilio.com/docs/voice.xml")); 
    params.add(new BasicNameValuePair("To", "+14155551212")); 
    params.add(new BasicNameValuePair("From", "+18668675309")); 
    params.add(new BasicNameValuePair("Method", "GET")); 
    params.add(new BasicNameValuePair("StatusCallback", "https://www.myapp.com/events")); 
    params.add(new BasicNameValuePair("StatusCallbackMethod", "POST")); 
    params.add(new BasicNameValuePair("StatusCallbackEvent", "initiated")); 
    params.add(new BasicNameValuePair("StatusCallbackEvent", "ringing")); 
    params.add(new BasicNameValuePair("StatusCallbackEvent", "answered")); 
    params.add(new BasicNameValuePair("StatusCallbackEvent", "completed")); 


    CallFactory callFactory = client.getAccount().getCallFactory(); 
    Call call = callFactory.create(params); 
    System.out.println(call.getSid()); 
    } 
}
