How to send a SOAP request to a web service over HTTPS over an X509 certificate in Javascript?

Question

JavaScript

Given:
- SOAP web service of the Rosreestr portal, connection to which is via HTTPS, client authentication by X509 certificate, private key algorithm - GOST R 34.11-94;
- A client machine with CryptoPro installed (a cryptographic provider containing algorithms for encryption and signing, including GOST R 34.11-94) and CadesPlugin (allows you to use CryptoPro signature and encryption functions in javascript).

It is necessary:
​​- Send a request from the client machine through the browser, i.e. from the html page, using javascript.

Is it possible? What libraries or frameworks solve this problem?

Answer 1

It seems to me that you will not be able to make any SOAP request to a foreign domain due to browser restrictions (cross-domain request).
