Solved POST webrequest not working (wrong command parameter)

Hello again

i tryed using the Example Snippet in the Doc for POST-Request (so i customized nothing, in the first place)

but its not working

Code:

[Oxide] 21:30 [Error] Failed to call hook 'PostRequest' on plugin 'MyPlugin v0.1
.0' (InvalidCastException: Cannot cast from source type to destination type.)
[Oxide] 21:30 [Debug]  at Oxide.Plugins.MyPlugin.DirectCallHook (System.String
name, System.Object& ret, System.Object[] args) [0x00000] in <filename unknown>:
0

 args) [0x00000] in <filename unknown>:0
  at Oxide.Core.Plugins.Plugin.CallHook (System.String hookname, System.Object[]
 args) [0x00000] in <filename unknown>:0

 

Sorry.

The Error that occurs

Code:

[Oxide] 21:30 [Error] Failed to call hook 'PostRequest' on plugin 'MyPlugin v0.1
.0' (InvalidCastException: Cannot cast from source type to destination type.)

Im using this exactly this Code:

Code:

[ChatCommand("post")]
  void PostRequest(IPlayer player, string command, string[] args)
  {
  // Set a timeout (in milliseconds)
  var timeout = 200f;  // Set some custom request headers (eg. for HTTP Basic Auth)
  var headers = new Dictionary<string, string> { { "header", "value" } };  webrequest.EnqueuePost("http://www.google.com/search?q=oxide", "param1=value1&param2=value2", (code, response) => PostCallback(code, response, player), this, headers, timeout);
  }  void PostCallback(int code, string response, IPlayer player)
  {
  if (response == null || code != 200)
  {
  hurt.BroadcastChat("Error: - Couldn't get an answer from Google for {player.Nickname}");
  return;
  }
  hurt.BroadcastChat("Google answered for " + player.Nickname + ": " + response);
  }

 

Okay:
1. Thank you
2. The API forces me to give a String as a Post Parameter.

What if i want to POST a JSON-Object?
I think simple casting is not a good solution or?
