My simple HTTPS Java server does not receive form's POST data
Question
With much efforts, I finally was able to write a simple HTTPS server in Java to handle HTTPS requests. What I eventually should do is to get the data from the form, process it, and return the results back. Just as a start, in this simple example I just want to return the "value" of the submitted option. Unfortunately when I'm printing what the server has received, I don't see any POST data except POST /run.html HTTP/1.1 . What is the problem, and how can I add this feature into it?
PS: don't forget to create a keystore for the SSL and write the info in the code if you want to test.
The POST request I get is this (even the length is 41, which I guess should be correct for a missing data of list=capacity.3Mbps_400RTT_PER_0.0001.txt ):
POST /run.html HTTP/1.1
Accept: text/html, application/xhtml+xml, */*
Referer: https://localhost:8888/
Accept-Language: en-US
User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0) like Gecko
Content-Type: application/x-www-form-urlencoded
Accept-Encoding: gzip, deflate
Host: localhost:8888
Content-Length: 41
Connection: Keep-Alive
Cache-Control: no-cache
Here is my simple form in HTML (which actually I'm supposed to receive its HTML source from server):
<html><body>
<p>
<h3> Please select a configuration below to run the emulator.</h3>
<form action="run.html" method="POST">
<select name="list">
<option name="400" value="capacity.3Mbps_400RTT_PER_0.0001.txt">capacity.3Mbps_400RTT_PER_0.0001</option>
<option name="100" value="capacity.3Mbps_100RTT_PER_0.00001.txt">capacity.3Mbps_100RTT_PER_0.00001</option>
<option name="200" value="capacity.3Mbps_200RTT_PER_0.0001.txt">capacity.3Mbps_200RTT_PER_0.0001</option>
</select>
<input type="submit" value="Run Emulator!">
</form>
</body></html>

How are you handling the POST method in your server? I see you have this portion for the GET method, looks like you need to add an else/if statement for POST method.
if(m.contains("GET")) {
// return page HTML
} else if(m.contains("POST")) {
// process form data
// return page HTML
}
