[Issue] $args returning null

[GamerMedic]

The $args param is always returning as null.

I get the [Websend] The server responded to the request with a 2xx code. Assuming request OK. (OK) message on my Minecraft server console, but the Empty argument! Don't just call ws/websend, add more arguments. string on the minecraft.php URL, and a Failed to connect error when trying to go PHP -> Spigot using the ExternalTimeSet.php test script.

Spigot seems to be reading the php page because any additional input I put on the page is included on the Minecraft console log, but my website is, seemingly, not receiving or sending data.

Any ideas?

EDIT: I'm using an additional port on my Minecraft server which is definitely open, and the php script is using the open port. Minecraft version: Paper 1.16.2. Websend version: 5.0.

ok let's take one at a time and see where we get:

the message "Empty argument!" is because you need to run a command such as "/ws test test1 test2" from the minecraft server.
Those test.. are your arguments. Please try that. you can change the top of minecraft.php to

<?php 
global $CONFIG;

$CONFIG['checkpass'] = "PutYourPasswordHere";
$CONFIG['hashAlgorithm'] = "sha512";

$json = websend_connect();
// get the command arguments and return them to the console:
$arguments = $_POST['args'];
websend_command('PrintToConsole', 'you sent the arguments: '. implode(",", $arguments));

You can get the full file with this change here:
https://github.com/uncovery/Websend/blob/master/src/main/resources/minecraft.php

The above change however won't do anything unless you execute the command with arguments on the console of the minecraft server (or as a player).
and see if that does it. Once that works, we can check the rest.

Please try the latest version, this should make debugging this specific issue easier:

I was always using arguments with the /ws command, but I tried it again anyway with the altered code you suggested.

Here are my logs:

PHP

[15-Jan-2021 00:17:15 Europe/London] Websend error: Invalid hash!
[15-Jan-2021 00:17:18 Europe/London] Websend error: Empty argument! Don't just call ws/websend, add more arguments.

Minecraft

[Server] INFO PlayerName issued server command: /ws test test1 test2
14.01 19:17:15 [Server] INFO [Websend] The server responded to the request with a 2xx code. Assuming request OK. (OK)
14.01 19:17:15 [Server] INFO [Websend] Command parsing: Execute JSON commnad {"action":"PrintToConsole","targetPlayer":null,"command":"Websend Error: Invalid hash!"}

14.01 19:17:15 [Server] INFO [Websend] Websend Error: Invalid hash!

The password is the same in all Websend files, and the hash is sha512 in all of the files (hash was left as default, I only changed the password, which was copy and pasted to each file). It certainly shouldn't make a difference, but for clarity, I'm using an alphanumeric password with no special characters, and the password is greater than 16 chars in length.

N.B. Ignore the time discrepancy, I have a remote hosted Minecraft server which uses a different timezone to the one I'm in.

No PHP error.

New error sending PHP -> Spigot

PHP

[15-Jan-2021 00:45:01 Europe/London] Websend connect() failed: Websend::__set_state(array(
   'timeout' => 3600,
   'hashAlgorithm' => 'sha512',

   'host' => 're.da.ct.ed', // trusted.txt is using trust_all
   'port' => 8113, //opened port, ALTPORT is set to this port
   'stream' => false,
))

[uncovery]

ok so if the spigot->php does not show errors, is it working now? if not, can you post a "var_dump($_POST);" to a pastebin site?

regarding the php->spigot, I have to dive into the debug on the websend side there. Since I only took over the project from someone else, and it works for me, I never looked at that in detail. Will let you know if I find some code to improve.

[GamerMedic]

Spigot->php is working now, after updating the files as you suggested. But php->spigot is throwing a Failed to connect message with this error:

[15-Jan-2021 00:45:01 Europe/London] Websend connect() failed: Websend::__set_state(array(
   'timeout' => 3600,
   'hashAlgorithm' => 'sha512',
   'password' => ' **** ', // pass is the same in PHP and YAML files
   'host' => 're.da.ct.ed', // trusted.txt is using trust_all
   'port' => 8113, //opened port, ALTPORT is set to this port
   'stream' => false,
))

(Obviously with the proper password and host)

[uncovery]

ok, great, then let me check if I can get more debug messages into it. btw I assume that
'password' => ' **** ' < you don't actually have spaces in there, right?

[GamerMedic]

No, no spaces

[uncovery]

Ok, please try the new release 5.2 and

• replace all the php files for testing with the new ones
• copy-paste the minecraft console output relating to websend here
• copy-paste the complete php output of the external timeset here as well.

[uncovery]

can you please use the new .php files from the zip that has all the error reporting on and paste those errors here as well?
Also please the startup-messages from websend in the console log?

as of now I can only assume that your port is not actually open, maybe iptables or another firewall is blocking it?
Is the server on linux or windows?

thanks!

[GamerMedic]

No other errors are showing. I've double checked that the port is definitely open, but I'll delve into it a bit more and if I get it working then I'll post the solution here.

My server is running Linux.

[uncovery]

check this one here to make sure the port is used by websend:
