I formatted the string according to the xml rpc but got an error

[KoNekoD]

<?xml version="1.0"?>
<methodCall>
<methodName>supervisor.stopProcess</methodName>
<params>
    <param>
        <value>
            <struct>
                <member>
                    <name>name</name>
                    <value><string>php-fpm:php-fpm</string></value>

Works with

<?xml version="1.0"?>
<methodCall><methodName>supervisor.stopProcess</methodName><params><name>php-fpm:php-fpm</name><wait>1</wait></params></methodCall>

[KoNekoD]

In general supervisor does not support encoding it seems, bug...

[KoNekoD]

The issue is solved, in general XML RPC is a BULLSHIT!!!! And supervisor implements it in its own way, it accepts according to wrong structure.

Expected params

• param -- value --- struct ---- ...

Actually params:

• struct

[KoNekoD]

In general, the main thing is not to be mistaken in the arguments :0

[KoNekoD]

That's roughly the structure right now

params:

• string --- ...
• struct --- ...

You can also use this

params:

value. struct ...

[KoNekoD]

Anyway, it's a pain, but I've implemented it for myself.

Closing since the issue is solved.
