authorization in WebRequest

New comment
 

Hi,

The exante platform has its own http api and I want to send an http request using the language mql4.

For example, in python, a simple request for the get method

requests.get(url = "https://api-demo.exante.eu/md/1.0/symbols/AAPL.NASDAQ", auth = ("<application id>: <access key>"))

I need to write this code in mql4,here with url arguments everything is clear, here is the problem with the auth argument, where should I write <application id>: <access key>

Basic http authentication is used with access key as password and application ID (not client ID) as username.

So you get your answer, you need to add a header with WebRequest, the credentials need to be Base64 encoded.

Basic access authentication - Wikipedia
  • en.wikipedia.org
In the context of an HTTP transaction, basic access authentication is a method for an HTTP user agent (e.g. a web browser) to provide a user name and password when making a request. In basic HTTP authentication, a request contains a header field in the form of , where credentials is the base64 encoding of id and password joined by a single...

Таким образом, вы получите свой ответ, вам нужно добавить заголовок с WebRequest, учетные данные должны быть в кодировке Base64.

Thanks, I write below code

but can't connect successfully. Where I made a mistake ?

   
   // <application id> = 1eab640c-8798-43b3-9fc2-f8deb990a62f
   // <access key> = lxXig0zIODcGncXeeeVn
   // To enable access to the server, I add URL "https://api-demo.exante.eu/md/1.0/symbols/AAPL.NASDAQ"

   int res;
   char post[], result[];
   string headers = "Login=1eab640c-8798-43b3-9fc2-f8deb990a62f&Password=lxXig0zIODcGncXeeeVn";

   res = WebRequest("GET", "https://api-demo.exante.eu/md/1.0/symbols/AAPL.NASDAQ", NULL, NULL, 0, post, 0, result, headers);
  
   Print(res); // show -1

The mistake is on the lack of  Base64 Encryption on the credentials
