短信不发送到手机上使用批量短信网站

Question

我正试图通过批量短信发送站点在移动设备上发送短信。我试图通过使用以下代码通过java api发送短信。它没有显示任何错误，但是没有发送消息。

 String urlParameters="usr=username &pwd=1234 &ph=9015569447 &text=Hello";
 //String request = "http://hapi.smsapi.org/SendSMS.aspx?";
 String request="http://WWW.BULKSMS.FELIXINDIA.COM/send.php?";
try{                        
URL url = new URL(request); 
HttpURLConnection connection = (HttpURLConnection) url.openConnection();           
connection.setDoOutput(true);
connection.setDoInput(true);
connection.setInstanceFollowRedirects(false); 
connection.setRequestMethod("POST"); 

connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded"); 
connection.setRequestProperty("charset", "utf-8");
connection.setRequestProperty("Content-Length", "" +         Integer.toString(urlParameters.getBytes().length));
  connection.setUseCaches (false);
DataOutputStream wr = new DataOutputStream(connection.getOutputStream ());
wr.writeBytes(urlParameters);
    wr.flush();
wr.close();
connection.disconnect();
}
catch(Exception ex)
{
 System.out.print(ex);
}

Answer 1

您应该在写入流之后检查响应代码，以便能够判断发生了什么:

int rc = connection.getResponseCode();
if(rc==200)
{
    //no http response code error
    //read the result from the server
    rd = new BufferedReader(new InputStreamReader(connection.getInputStream()));
    sb = new StringBuilder();
    //get the returned data too
    returnString=sb.toString();
}
else
{
    System.out.println("http response code error: "+rc+"n");
}

(从这里粘贴的代码)

同样永远不要这样做:

catch(Exception ex)
{
    System.out.print(ex);
}

这对你的健康是有害的:下一个调试你的代码会给你一个沉重的打击，找到这个对象!

catch(Exception ex)
{
    ex.printStackTrace();
}

或

catch(Exception ex)
{
    LOG.error("Something went wrong (adequate error message here please)", ex);
}

必须完成!

我看到请求参数之间有一些空格URL:

 String urlParameters="usr=username&pwd=1234&ph=9015569447&text=Hello";

这可能是问题所在
