[SOLVED] Parsing MT4 config files

Parsing MT4 config files

I'm trying to write an install script for an MT4 expert advisor. Part of the installation process includes adding an allowed WebRequest URL. I assume this is saved as a setting in C:\Users\{User ID}\AppData\Roaming\MetaQuotes\Terminal\{Terminal ID}\config\experts.ini as I can see the allowed URLs there, but I cannot parse this data as no editor I have can decode it. Is this file parsed using a proprietary encoding or is it encrypted in some way? Any help here would be appreciated.

Solution

The only solution I could think of to address this issue was to create my own HTTP web request library, here, and use it to submit HTTP requests.

#include <mql-http/Request.mqh>
#include <mql5-json/Json.mqh>

int SendWebRequest(const object request) {

   string body = ConvertToJSON(request);  // You'll have to write your own JSON converter
   
   HttpRequest req("POST", m_send_addr, body);
   req.AddHeader("Accept", "application/json");
   req.AddHeader("Authorization", m_auth_header);
   
   HttpResponse resp;
   int errCode = req.Send(resp);
   if (errCode != 0) {
      return errCode;
   } else if (resp.StatusCode != 200) {
      return resp.StatusCode;
   } else {
      return 0;
   }
}

At the moment this is pretty bare-bones but it's open-source so feel free to modify and contribute.
