如何使用 Twilio Java API 获取录制的 wav 文件

Question

有人可以指出我，使用Twilio Java API，不是！REST 请求，如何获取具体调用的录制文件 (.wav(。

我已经阅读了所有相关的记录(https://support.twilio.com/hc/en-us/sections/205104748-Recording(文章，但没有一篇展示如何使用Java API做到这一点。

我使用此代码作为起点，假设已知CALL_SID：

import com.twilio.Twilio;
import com.twilio.base.ResourceSet;
import com.twilio.rest.api.v2010.account.Recording;
import com.twilio.rest.api.v2010.account.RecordingReader;
public class DeleteRecordings1 {
private static final String ACCOUNT_SID = "ACXXXXXXXXXXXXXXXXX";
private static final String AUTH_TOKEN = "999aa999aaa999aaaa999";
private static final String CALL_SID = "CA83837718818gdgdg";
public static void main(String[] args) {
try {       
Twilio.init(ACCOUNT_SID, AUTH_TOKEN);
RecordingReader recordingReader = Recording.reader();
recordingReader.setCallSid(CALL_SID);
ResourceSet<Recording> recordings = recordingReader.read();
String recordingSid;
for (Recording recording: recordings) { 
recordingSid = recording.getSid();              
//HERE! I want to restore the .wav file associated with that RECORD_SID ?¿
}                       
} catch (Exception e) {
e.printStackTrace();
}
}
}

我放了最终代码，以防它可以帮助某人：

import java.io.File;
import java.io.InputStream;
import java.net.URL;
import java.nio.file.Files;
import java.nio.file.Paths;
import java.nio.file.StandardCopyOption;
import com.twilio.Twilio;
import com.twilio.base.ResourceSet;
import com.twilio.rest.api.v2010.account.Recording;
import com.twilio.rest.api.v2010.account.RecordingReader;
public class GetCallRecordings {
private static final String ACCOUNT_SID = "ACXXXXXXXXXXXXXXXXX";
private static final String AUTH_TOKEN = "999aa999aaa999aaaa999";
private static final String CALL_SID = "CA83837718818gdgdg";
private static final String TWILIO_RES_URL = "https://api.twilio.com/2010-04-01/Accounts";
private static final String REC_EXT = ".mp3";
private static final String RUTA_RECS = "C:/recursos/grabaciones/";
public static void main(String[] args) {
try {
Twilio.init(ACCOUNT_SID, AUTH_TOKEN);
RecordingReader recordingReader = Recording.reader();
recordingReader.setCallSid(CALL_SID);
ResourceSet<Recording> recordings = recordingReader.read();
String recordingSid;
String urlGrabacion;
String locGrabacion;
InputStream in;
for (Recording recording : recordings) {
recordingSid = recording.getSid();
urlGrabacion = TWILIO_RES_URL + "/" + ACCOUNT_SID + "/Recordings/" + recordingSid + REC_EXT;
locGrabacion = RUTA_RECS + CALL_SID + "_" + recordingSid + REC_EXT;
System.out.println("Recuperando grabacion " + recordingSid);
System.out.println("Ubicacion remota " + urlGrabacion);
if (!new File(RUTA_RECS).exists()) {
new File(RUTA_RECS).mkdirs();
}
in = new URL(urlGrabacion).openStream();
Files.copy(in, Paths.get(locGrabacion), StandardCopyOption.REPLACE_EXISTING);
System.out.println("Ubicacion local " + locGrabacion);
in.close();
}
} catch (Exception e) {
e.printStackTrace();
}
}
}

一旦你知道recordingSid例如RE557ce644e5ab84fa21cc21112e22c485

您可以在https://api.twilio.com/2010-04-01/Accounts/ACXXXXX.../Recordings/RE557ce644e5ab84fa21cc21112e22c485.wav获取.wav文件

您可以在以下位置获取.mp3文件https://api.twilio.com/2010-04-01/Accounts/ACXXXXX.../Recordings/RE557ce644e5ab84fa21cc21112e22c485.mp3

其中ACXXXXX...是你的 Twilio 帐户 SID (ACCOUNT_SID(
