Sending sms via java

Question

I am going to send sms via java. The problem is the sms gateway ask me to send in this format

http://push1.maccesssmspush.com/servlet/com.aclwireless.pushconnectivity.listen
ers.TextListener?userId=xxxxx&pass=xxxx&appid=xxxx&subappid=xxxx&msgtyp
e=1&contenttype=1&selfid=true&to=9810790590,9810549717&from=ACL&dlrre
q=true&text=This+is+a+test+msg+from+ACL&alert=

The problem how to call this from a java application is it possible or does it need special libraries? IS it using HttpURLConnection will do the job? Thank you.

A Sample code I have done below is this correct.

URL sendSms1 = new URL("http://push1.maccesssmspush.com/servlet/com.aclwireless.pushconnectivity.listen
    ers.TextListener?userId=xxxxx&pass=xxxx&appid=xxxx&subappid=xxxx&msgtyp
    e=1&contenttype=1&selfid=true&to=9810790590,9810549717&from=ACL&dlrre
    q=true&text=This+is+a+test+msg+from+ACL&alert=");

URLConnection smsConn1 =
    sendSms1.openConnection();

Answer 1

It's just an HTTP call, you don't need anything special in Java (or any modern language, I expect). Just build up the string as appropriate*, then make an HTTP request to that URL.

Take a peek at the Sun tutorial Reading from and Writing to a URLConnection if you need to pick up the basics of how to do the request part in Java. This uses the built-in classes, I'm sure there are dozens of libraries that handles connections in funky and/or convenient ways too, so by all means use one of those if you're familiar with it.

*One potential gotcha which might not have occurred to you - your query string arguments will have to be URL-encoded. So the + characters for example in the text parameter, are encoded spaces (which would have a different meaning in the URL). Likewise, if you wanted to send a ? character in one of your parameters, it would have to appear as %3F. Have a look at the accepted answer to HTTP URL Address Encoding in Java for an example of how you might build the URL string safely.

Answer 2

It looks like a simple GET request, you can use Apache HttpClient libarary for executing such a request. Have a look into a tutorial by Vogella here: http://www.vogella.de/articles/ApacheHttpClient/article.html for sample source code and explanations.

Answer 3

You can try to use java.net.URL library。

like this

// at this before you need to generate the urlString as "http://push1.maccesssmspush.com/servlet/com.aclwireless.pushconnectivity.listen
ers.TextListener?userId=xxxxx&pass=xxxx&appid=xxxx&subappid=xxxx&msgtyp
e=1&contenttype=1&selfid=true&to=9810790590,9810549717&from=ACL&dlrre
q=true&text=This+is+a+test+msg+from+ACL&alert="

URL url = new URL(urlString);
// send sms
URLConnection urlConnection = url.openConnection();// open the url
// and you, also can get the feedback if you want
BufferedReader br = new BufferedReader(new InputStreamReader(
urlConnection.getInputStream()));

Answer 4

URL url = new URL("http://smscountry.com/SMSCwebservice.asp");
HttpURLConnection urlconnection = (HttpURLConnection) url.openConnection();

[Edit]

urlconnection.setRequestMethod("POST"); 
urlconnection.setRequestProperty("Content-Type","application/x-www-form-urlenc‌​oded");     
urlconnection.setDoOutput(true); 

OutputStreamWriter out = new OutputStreamWriter(urlconnection.getOutputStream());
out.write(postData); 
out.close(); 

BufferedReader in = new BufferedReader(new InputStreamReader(urlconnection.getInputStream()));

String decodedString; 

while ((decodedString = in.readLine()) != null) { 
  retval += decodedString; 
}
