Question

我想使用java API发送包含阿拉伯语消息的短信

mobily provider提供了一个java api来发送短信

我使用了这段代码：

public void sendMessage(String userName,String password,String sender,String message,String numbers){
            String para ="mobile=" + userName + "&password=" + password + "&numbers=" + numbers+ "&sender=" + sender + "&msg=" + convertUnicode(message) + "&applicationType=24";
            sendURL("http://www.mobily.ws/api/msgSend.php",para,1);
            System.out.println(getMessage());
    }



    public static String convertUnicode(String a) {
        int bufSize = 16;
        byte[] buffer = new byte[bufSize];
        String s = null;
        try {
            buffer=a.getBytes();
            s = bytesToHex(buffer,0,buffer.length);
            System.out.println("Hex: "+s);
        } catch (Exception e) {
            System.out.println(e.toString());
        }
        return s;
    }
    public static String bytesToHex(byte[] b, int off, int len) {
        StringBuffer buf = new StringBuffer();
        for (int j=0; j<len; j++)
            buf.append(byteToHex(b[off+j]));
            return buf.toString();
    }
    public static String byteToHex(byte b) {
        char[] a = { hexDigit[(b >> 4) & 0x0f], hexDigit[b & 0x0f] };
        return forDigits(new String(a));
    }
    public static String forDigits(String val){
        switch (val.length() ){
            case 1:return "000"+val;
            case 2:return "00"+val;
            case 3:return "0"+val;
            case 4:return ""+val;
            default:return val;
        }
    }


public void sendURL(String URL,String parameters,int operationNumber){
        try {
            URL url;
            URLConnection urlConnection;
            DataOutputStream outStream;
            // Create connection
            url = new URL(URL);
            urlConnection = url.openConnection();
            ((HttpURLConnection)urlConnection).setRequestMethod("POST");
            urlConnection.setDoInput(true);
            urlConnection.setDoOutput(true);
            urlConnection.setUseCaches(false);
            urlConnection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
            urlConnection.setRequestProperty("Content-Length", ""+ parameters.length());
            urlConnection.setRequestProperty("User-agent","Mozilla/4.0");
            // Create I/O streams
            outStream = new DataOutputStream(urlConnection.getOutputStream());
            // Send request
            outStream.writeBytes(parameters);
            outStream.flush();
            outStream.close();
            // Get Response
            BufferedReader rd = new BufferedReader(new InputStreamReader(urlConnection.getInputStream()));
            // - For debugging purposes only!
            String buffer;
            while((buffer = rd.readLine()) != null) {
                try{
                    selectedMessage(Integer.parseInt(buffer),operationNumber);
                }catch(Exception ex){
                    balance=buffer;
                }
            }
            // Close I/O streams
            rd.close();
            outStream.close();
        }
        catch(Exception ex) {
            System.out.println("Exception cought:\n"+ ex.toString());
        }
    }

问题是缓冲区值是“-1 - ”

这一行填写在这一行：

buffer = rd.readLine（）

所以我总是发现自己处于这个例外

}catch(Exception ex){
                  balance=buffer;
              }

sendMessage 方法中发送的参数：

发件人：شارععلي

消息：وجهتإلى

号码：00966569114455

已更新：

我到了发送英文信息

发件人：测试

消息：测试

在此行while((buffer = rd.readLine()) != null) {

中

缓冲区的值等于 1

问题仅适用于发送阿拉伯语消息

我尝试使用以下方法更改代码但未成功：

   while((buffer = rd.readLine()) != null) {

                try{
                      buffer = buffer.replaceAll("(-?[0-9]+)([^0-9]*)?","$1");
                    buffer=buffer.replace("-", "");
                    selectedMessage(Integer.parseInt(buffer),operationNumber);
                }catch(Exception ex){
                    balance=buffer;
                }

也在 sendURL 方法的这一行：

 urlConnection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded; charset=utf-8");

并在 convertUnicode 方法的这一行：

buffer=a.getBytes(StandardCharsets.UTF_8);

这是我的函数，它返回最后的消息：

public void selectedMessage(int value,int operationNumber){
    switch(operationNumber){
        case 1:switch(value){
                    case 1:msg= "SUCCESS";break;
                    case 2:msg="ERROR";break;

               }break;

        }
}

使用我修改过的代码我强制缓冲区值等于1

sendURL方法

参数的值为：

mobile=966556541236&password=123654&numbers=966569114455&sender=شارع علي&msg=00D800A700D9008400D9008500D800B900D800A700D9008500D9008400D800A9002000D800B100D9008200D9008500D9008800D800AC00D9008700D800AA002000D800A500D9008400D90089002000D9008600D800B800D800A700D90085002000D9008400D9008400D800AA00D800AF00D800B100D9008A00D800A8&applicationType=24

您可以考虑先在输入上执行RegEx replaceAll，以过滤输入。

实施例

buffer = rd.readLine().replaceAll("(-?[0-9]+)([^0-9]*)","$1");

这将转换输入如下：

-1-    ->    -1
-1     ->    -1
 1-    ->     1

java.lang.NumberFormatException：对于输入字符串：“ - 1 - ”
