Twilio API傻眼发送一条简单的短信

Question

我有一个Twilio的帐户，我正在使用它以编程方式通过PHP脚本发送自己的短信。 现在我想在我正在编写的服务中使用此功能。 我的问题是缺乏关于如何在Java中实现功能的好例子。 似乎只有一个我想要做的例子，但我在eclipse（霓虹灯）中不断出现错误，说PhoneNumber（String）的构造函数中有错误。 我先向您展示我的代码然后再解释一下。

我有这两个类，一个用于存储我的用户凭据，另一个用于保存邮件收件人数据（名称和电话号码）.... ps原谅格式。

/**
 * Class contains my credentials with Twilio.com
 * and are read from a file located at /sms_textdata/twiliocredentials.txt
 */
public class SMSCredentials
{
private final String userID;
private final String accessCode;
private final String senderNumber;

public SMSCredentials(String userID,  String accessCode, String senderNumber)
{
    this.userID = userID;
    this.accessCode = accessCode;
    this.senderNumber = senderNumber;
}

public String getUserID()
{
    return userID;
}

public String getAccessCode()
{
    return accessCode;
}

public String getSenderNumber()
{
    return senderNumber;
}
}



/**
 * A class that models a recipient of a text message
 * Recipient list is located at /sms_textdata/smsrecipients.txt
 */
public class MessageRecipient
{
//first name
private String name;
//phone number
private String phoneNumber;

public MessageRecipient(String name, String phoneNumber)
{
    this.name = name;
    this.phoneNumber = phoneNumber;
}

public String getName()
{
    return name;
}

public String getNumber()
{
    return phoneNumber;
}
}

我实现了上面两个类的第三个类。 我打算从两个文本文件中读取凭证数据和收件人数据。

import java.io.File;
import java.io.IOException;
import java.util.ArrayList;
import java.util.Scanner;

/**
*  This class is responsible for sending  SMS text messages
* to a list of recipients.
*/
public class SMSAlert
{
private SMSCredentials credentials;
private ArrayList<MessageRecipient> recipients;

public SMSAlert()
{
    this.getCredentials();
    this.createRecipientList();
}

/**
* send a SMS text message to a list of recipients
*/
public void sendSMSTextMessage()
{
    //send messages to a list of recipients 
    Twilio.init(credentials.getUserID(), credentials.getAccessCode());

    for(MessageRecipient rec : recipients)
    {
        Message message = Message.creator(new PhoneNumber(rec.getNumber()), 
                                        new PhoneNumber(credentials.getSenderNumber()),
                                        " Hey " + rec.getName() + " the garage door is open!")
                                        .create();
        //System.out.println(message.getSid());
    }
}

/**

private void getCredentials()
{
    String credentialsFile;
    Scanner credentialIn = null;
    String id = null;
    String code = null;
    String number = null;

    try
    {
        credentialsFile = "~/Documents/twiliocredentials.txt";
        credentialIn = new Scanner(new File(credentialsFile));

        // as there are only two strings in this file, the loop will execute
        //only once, and assign the values to a new object of type SMSCredentials.
        while(credentialIn.hasNext())
        {
            id = credentialIn.next();
            code = credentialIn.next();
            number = credentialIn.next();
        }

        //create the credentials object from a file
        credentials = new SMSCredentials(id, code, number);
    }
    catch(IOException e)
    {
        e.getStackTrace();
    }
    finally
    {
        credentialIn.close();
    }
}

/**
* create a list of recipients from a file to send text messages to.
*/
private void createRecipientList()
{
    recipients = new ArrayList<MessageRecipient>();
    String userFile;
    Scanner recipientsIn = null;
    String name;
    String number;

    try
    {
        userFile = "~/Documents/smsrecipients.txt";
        recipientsIn = new Scanner(new File(userFile));

        //file format is name : number pair on one line of text
        //one object is instantiated per line/user
        while(recipientsIn.hasNext())
        {
            name = recipientsIn.next();
            number = recipientsIn.next();

            //instantiate and add a user to the list
            recipients.add(new MessageRecipient(name, number));
        }           
    }
    catch(IOException e)
    {
        e.printStackTrace();
    }
    finally
    {
        recipientsIn.close();
    }
}
}

我在eclipse中遇到的错误来自sendSMSTextMessage（）方法。 Eclipse给了我错误：

The constructor PhoneNumber(String) is undefined

这是一个Maven项目，我拥有所有依赖项.....我缺少什么？ 有没有人有更好的方式让我在Java中发送多条短信？ 我不应该有“发送消息”的方法吗？

谢谢你的帮助......我的大脑被炒了......

Twilio开发者传道者在这里。

看起来你输入了错误的PhoneNumber定义。 您是从com.twilio.rest.lookups.v1.PhoneNumber获取的，但是使用Java导入发送SMS消息的Twilio指南导入了com.twilio.type.PhoneNumber 。

如果这有帮助，请告诉我。
