Extension to make http requests, currently supporting:

  • GET
  • POST
  • PATCH
  • DELETE
  • PUT

 

First parameter is the mode.

Second is the method.

Third is the url.

Fourth is the authorization, if no authorization needed just pass null

Fifth is the request body, only used by POST, PATCH and PUT, if no body needed just pass {}

 

GET request example:

"ArmaRequests" callExtension "0|GET|http://headers.jsontest.com/|null";

waitUntil {sleep 1; "ArmaRequests" callExtension "2" == "OK"};

_response = "ArmaRequests" callExtension "1";

_parsedResponse = parseSimpleArray _response;

_code = _parsedResponse select 0;

_data = _parsedResponse select 1;

//Response => [["X-Cloud-Trace-Context","47e3637379c2b3d638285b973e0e4f96/4228286279360018440"],["Host","headers.jsontest.com"]]

 

POST request example:

"ArmaRequests" callExtension '0|POST|url|Bot ksZc83aS|{"Number": 4, "String": "String"}';

waitUntil {sleep 1; "ArmaRequests" callExtension "2" == "OK"};

_response = "ArmaRequests" callExtension "1";

_parsedResponse = parseSimpleArray _response;

_code = _parsedResponse select 0;

_data = _parsedResponse select 1;

 

 

Every response comes with a status code

0: All data received
1: There's still data to receive
9: Error

The codes you can use are

0: New request
1: Receive data
2: Get extension status
3: Parse JSON //Example: "ArmaRequests" callExtensions '3|{"age": 80}';

Due to string length limitations, if the response exceeds that limit it will be sent in chunks with status code 1, to receive the chunk use

_fullResponse = "";

//
_chunkResponse = "ArmaRequests" callExtension "1";
_parsedChunkResponse = parseSimpleArray _chunkResponse;
_code = _chunkResponse select 0;
_data = _chunkResponse select 1;
_fullResponse = _fullResponse + _data;

//You must repeat the receiving process until it responds with a code 0

When there's no more data left, it will respond with a code 0.

JSON responses are automatically parsed into arrays, all common variables type are supported.

 

Example code 

_fullResponse = "";
  "ArmaRequests" callExtension "0|GET|http://headers.jsontest.com/|null"; //Send request
  waitUntil {sleep 1; "ArmaRequests" callExtension "2" == "OK"};

  _response = "ArmaRequests" callExtension "1";
  _parsedResponse = parseSimpleArray _response; //Parse response

  _code = _parsedResponse select 0; //Save code and data
  _data = _parsedResponse select 1;

  if (_code != 9) then { //Check if is a error
  _fullResponse = _data; //Assign the data in the full response

  while {_code == 1} do { //if there's more data receive it
    _chunkResponse = "ArmaRequests" callExtension "1"; //Receive next chunk data
    _parsedChunkResponse = parseSimpleArray _chunkResponse; //Parse the chunk data
    _code = _parsedChunkResponse select 0; //Update the status code
    _data = _parsedChunkResponse select 1; //Save the data
    if (_code == 9) exitWith {hint "Error : " + _data;}; //Check if is a error
    _fullResponse = _fullResponse + _data; //Append the chunk to the full response
  };

  hint str _fullResponse;
} else {
  hint "Error during request " + _data;
};

There's also a callback version

"ArmaRequestsCallback" callExtension "callbackFunction|Method|url|authorization?|body?";

Example using callback version and normal version

TAG_fnc_DiscordMessageSent = {
  params["_data"];
  //[["id","651314298001424405"],["type",0],["content","Hello"],["channel_id","649607925760786442"],["author",[["id","629121190182780929"],["username","Fantasia"],["avatar",null],["discriminator","2964"],["bot",true]]],["attachments",[]],["embeds",[]],["mentions",[]],["mention_roles",[]],["pinned",false],["mention_everyone",false],["tts",false],["timestamp","2019-12-03T06:50:29.478000+00:00"],["edited_timestamp",null],["flags",0],["nonce",null]]
  _content = (_data select 2) select 1;
  _username = (((_data select 4) select 1) select 1) select 1;
  _channelId = (_data select 3) select 1;
  "ArmaRequests" callExtension format["0|GET|https://discordapp.com/api/v6/channels/%1|Bot TOKEN|{}", _channelId];
  waitUntil {sleep 1; "ArmaRequests" callExtension "2" == "OK"};
  _channelData = (parseSimpleArray ("ArmaRequests" callExtension "1")) select 1;
  _channelName = (_channelData select 3) select 1;
  _guildId = (_channelData select 7) select 1;
  "ArmaRequests" callExtension format["0|GET|https://discordapp.com/api/v6/guilds/%1|Bot TOKEN|{}", _guildId];
  waitUntil {sleep 1; "ArmaRequests" callExtension "2" == "OK"};
  _guildData = (parseSimpleArray ("ArmaRequests" callExtension "1")) select 1;
  _guildName = (_guildData select 1) select 1;
  hint format["Sent %1 as %2 in the channel %3 of the guild %4", _content, _username, _channelName, _guildName];


};



addMissionEventHandler ["ExtensionCallback", {
  params["_name", "_function", "_data"];


  if (_name == "ArmaRequestsCallback_JSON") then {
      [parseSimpleArray _data] spawn (missionNamespace getVariable [_function, {
        diag_log format["ArmaRequestsCallback: Tried to call %1, but isn't defined", _function];
        }]);
  };

  if (_name == "ArmaRequestsCallback_Error") then {
    hint "Request error: " + _data;
  };

  if (_name == "ArmaRequestsCallback_TEXT") then {
    systemChat _data;
  };

}];

"ArmaRequestsCallback" callExtension "TAG_fnc_DiscordMessageSent|POST|https://discordapp.com/api/v6/channels/649607925760786442/messages|Bot BOT|{""content"": ""Hello"", ""tts"": false}";

Now I feel stupid for not thinking about callbacks, the problem is that I have no idea about changing the output size limit

Afaik callbacks have no limit. Besides the 10MB string limit I assume.

Strange, when I try sending more characters than the output size it throws me buffer overrun

Okey, no more freezing, also the json responses are parsed to arrays (The downside is that only works with numbers, strings, booleans and null values). It looks like the output max size is set by the engine so i can't get rid of it.

I'm talking about callbacks, not the normal callExtension stuff.

I tried it first, but the game or c#, converts the parameters to strings even if they already are. Making "string" to """string"""

yes, it makes it easy to test what type of argument you passed, if 1st char is " - it is a string. It is better than do manual parsing looking for those delimiters
