Question

Looking for a bit of help, I have currently written a HTTP server. It currently handles GET requests fine. However, whilst using POST the buffered reader seems to hang. When the request is stopped the rest of the input stream is read via the buffered reader. I have found a few things on google. I have tried changing the CRLF and the protocol version from 1.1 to 1.0 (browsers automatically make requests as 1.1) Any ideas or help would be appreciated. Thanks

This is not safe! But shows how to get the POST data during an Input Stream after the initial HTTP Headers.

This also only works for POST data coming in as “example=true&bad=false” etc.

private HashMap hashMap = new HashMap();
private StringBuffer buff = new StringBuffer();
private int c = 0;
private String[] post;    public PostInputStream(InputStream in) {

    try {
        //Initalizes avaliable buff
        if (in.available() != 0) {
            this.buff.appendCodePoint((this.c = in.read()));
            while (0 != in.available()) {
                //Console.output(buff.toString());
                buff.appendCodePoint((this.c = in.read()));
            }

            this.post = buff.toString().split("&");

            for (int i = 0; i < this.post.length; i++) {
                String[] n = this.post[i].split("=");
                if (n.length == 2) {
                    hashMap.put(URLDecoder.decode(n[0], "UTF-8"), URLDecoder.decode(n[1], "UTF-8"));
                } else {
                    Console.error("Malformed Post Request.");
                }
            }
        } else {
            Console.error("No POST Data");
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
}
