Android自动获取短信验证码

　　主要就是实时获取短信信息。

public class SMSReceiver extends BroadcastReceiver{

   private String verifyCode="";

    public static final String TAG = "SMSReceiver";

    public static final String SMS_RECEIVED_ACTION = "android.provider.Telephony.SMS_RECEIVED";

    @Override

    public void onReceive(Context context, Intent intent){

       if (intent.getAction().equals(SMS_RECEIVED_ACTION)){

           SmsMessage[] messages = getMessagesFromIntent(intent);

           for (SmsMessage message : messages){

              Log.i(TAG, message.getOriginatingAddress() + " : " +

                  message.getDisplayOriginatingAddress() + " : " +

                  message.getDisplayMessageBody() + " : " +

                  message.getTimestampMillis());

              String smsContent=message.getDisplayMessageBody();

              Log.i(TAG, smsContent);             

              writeFile(smsContent);//将短信内容写入SD卡

           }

       }

    }

 public final SmsMessage[] getMessagesFromIntent(Intent intent){

        Object[] messages = (Object[]) intent.getSerializableExtra("pdus");

        byte[][] pduObjs = new byte[messages.length][];

        for (int i = 0; i < messages.length; i++)

        {

            pduObjs[i] = (byte[]) messages[i];

        }

        byte[][] pdus = new byte[pduObjs.length][];

        int pduCount = pdus.length;

        SmsMessage[] msgs = new SmsMessage[pduCount];

        for (int i = 0; i < pduCount; i++)        {

            pdus[i] = pduObjs[i];

            msgs[i] = SmsMessage.createFromPdu(pdus[i]);

        return msgs;

  //将短信内容写到SD卡上的文件里，便于将文件pull到PC，这样可方便其它如WWW/WAP平台的自动化 

    @SuppressLint("SdCardPath")

 public void writeFile(String str){

     String filePath="/mnt/sdcard/verifyCode.txt";     

     byte [] bytes = str.getBytes();

     try{

     File file=new File(filePath);

     file.createNewFile();

     FileOutputStream fos=new FileOutputStream(file);

     fos.write(bytes);

     fos.close();

     }catch(IOException e){

      e.printStackTrace();

     }      

　　如此当有短信收到时就可以将短信内容写到SD卡中的文件里

　　在另一个java类中写个读取文件内容的方法，并在写测试用例过程中，将得到的String按验证码的具体位置截取即可。

public String read(String str) throws IOException{ 

  File file=new File(str);

  FileInputStream fis=new FileInputStream(file);

  StringBuffer sb=new StringBuffer();

  BufferedInputStream bis=new BufferedInputStream(fis);

  BufferedReader  read = new BufferedReader (new InputStreamReader(bis));

  int c=0;

  while ((c=read.read())!=-1) {

            sb.append((char) c);

  read.close();

  bis.close();

  fis.close();

  Log.i(TAG, sb.toString());  

  String verify=sb.toString();  

  return verify;

 }

　　最后需要在manifest中增加申明，且注册权限

<receiver android:name="com.cplatform.surfdesktop.test.util.SMSReceiver">

<intent-filter>

<action android:name="android.provider.Telephony.SMS_RECEIVED" />

</intent-filter>

</receiver>

<uses-permission android:name="android.permission.RECEIVE_SMS"></uses-permission>

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission>

<uses-permission android:name="android.permission.READ_SMS"/>

　　测试过程中需要用到短信验证码时就可以实时获取了
