How to read the single header value when it contains special characters in Ballerina

Question

I need to read the "X-JWT-Assertion" with the request.

Usually, we could use the following technique to read "Connection" header parameter.

resource function get menu(@http:Header string Connection) returns json {}

But when the header value contains special characters, it gives an error. Error

resource function get menu(@http:Header string X-JWT-Assertion) returns json {}

How to use refer to values with special characters in parameters in the resource definition?

Answer 1

You have to use \ to escape -.

E.g.,

import ballerina/http;

service on new http:Listener(8080) {
    resource function get menu(@http:Header string X\-JWT\-Assertion) returns json {

    }
}
