webrequest2

A more powerful, drop-in replacement for the Metatrader 5 Webrequest() method. Based on wininet.dll

Highlights

• Interface is fully compatible with the original WebRequest()
• Use non standard Ports
• Allow self signed ssl certs

Interface

int  WebRequest2(
   const string      method,                // HTTP method
   const string      url,                   // URL
   const string      headers,               // headers 
   int               timeout,               // timeout
   char              &data[],               // the array of the HTTP message body
   char              &result[],             // an array containing server response data
   string            &result_headers,       // headers of server response
   const int         port=NULL,             // Define custom port
   const bool        allowInsecure=false,   // Allow self signed certs
   const bool        useSSL=NULL            // Use SSL encrypted connection
   );

Return value HTTP server response code or -1 for an error.

Remarks

If allowInsecure is set to true the following flags are set:

SECURITY_FLAG_IGNORE_UNKNOWN_CA
INTERNET_FLAG_IGNORE_CERT_DATE_INVALID
SECURITY_FLAG_IGNORE_CERT_CN_INVALID
SECURITY_FLAG_IGNORE_REVOCATION

Please note that these Settings make SSL nearly useless. Therefore this flag should never be used in a environment where security matters! For reference check out: https://docs.microsoft.com/en-us/windows/desktop/winhttp/option-flags

The import "kernel32.dll" is used to retrieve the error messages.

Usage

1. Clone repo and copy the contents of Libraries folder into the corresponding folder of your MetaTrader installation.
2. Allow DLLs in your Terminal
3. Import Library:

#include <..\Libraries\WebRequest2\WebRequest2.mq5>

Test the library

You can use the script Scripts/TestWebRequest2.mq5 as an example of how you can detect your Public IP by doing an HTTP/HTTPS request using this WebRequest library.

1. Build the script Scripts/TestWebRequest2.mq5 using MetaEditor
2. Copy the file TestWebRequest2.ex5 that has been built to the Scripts folder in your MetaTrader5 profile folder
3. Open MetaTrader5 on a random chart
4. Allow DLLs in your Terminal
