I am using HttpURLConnection
to make a POST request to a local service deployed in my local created using JAVA Spark.I want to send some data in request body when I make the POST call using the HttpURLConnection but every time the request body in JAVA Spark is null. Below is the code I am using for this
Java Spark POST Service Handler
post("/", (req, res) -> {
System.out.println("Request Body: " + req.body());
return "Hello!!!!";
});
HTTPClass Making the post call
`public class HTTPClassExample{
public static void main(String[] args) {
try{
URL url = new URL("http://localhost:4567/");
HttpURLConnection httpCon = (HttpURLConnection) url.openConnection();
httpCon.setDoOutput(true);
httpCon.setRequestMethod("POST");
httpCon.connect();
OutputStream os = httpCon.getOutputStream();
OutputStreamWriter osw = new OutputStreamWriter(os, "UTF-8");
osw.write("Just Some Text");
System.out.println(httpCon.getResponseCode());
System.out.println(httpCon.getResponseMessage());
osw.flush();
osw.close();
}catch(Exception ex){
ex.printStackTrace();
}
}
}`
You should call
httpCon.connect();
only after you write your parameters in the body and not before. Your code should look like this:I posted with the requested data in XML format and the code look like this. You should add the request property Accept and Content-Type also.
