Can't get POST data in PHP from JAVA

Asked by At

I'm having a big trouble due to this problem. I can't get POST data in my PHP API from a java client. I'm having this problem only with Aruba hosting and not in local development or other hosting sites

this is the java request:

urlParameters = "name=Jack";
    byte[] postData = urlParameters.getBytes(StandardCharsets.UTF_8);

    try {

        URL myurl = new URL(url);
        con = (HttpURLConnection) myurl.openConnection();

        con.setRequestProperty("User-Agent", "Java client");
        con.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
        con.setRequestProperty("Content-Length", String.valueOf(postData.length));
        try (DataOutputStream wr = new DataOutputStream(con.getOutputStream())) {

        StringBuilder content;

        try (BufferedReader in = new BufferedReader(
                new InputStreamReader(con.getInputStream()))) {

            String line;
            content = new StringBuilder();

            while ((line = in.readLine()) != null) {


    }catch(MalformedURLException e){
        System.out.println("Error "+e);
    }catch(IOException e){
        System.out.println("Error "+e);
    finally {


Also in PHP i get:

if($_SERVER['REQUEST_METHOD'] === 'POST')  false
$entityBody = file_get_contents('php://input');  empty string

I also tried also changing php version but nothing... Thanks for help!

Using Wireshark I got this. I'm not an expert, but I think that the request is redirected by a proxy and becomes GET

enter image description here

ok I found another clue Even with a html form it doesn't work but only if I use the full site path

<form method="POST" action=""> doesn't work
<form method="POST" action="/php/api.php"> work

Now I think that is a permission problem, but I don't know what..

Solved by using address url in the following format "" instead of "" or "". Maybe due to a provider DNS settings
