emitAcceptHeader

Type: boolean | undefined | Default: true

Sends an Accept header derived from each operation's response content types, so servers that use content negotiation (for example versioned vendor media types like application/vnd.users+json;version=1.0) return the representation the generated method is prepared to parse.

The header value contains the content types declared on the operation's first success response that agree with the method's Angular responseType — advertising a type the method could not parse is deliberately avoided. Operations whose success response declares no content (for example 204 No Content) send no Accept header.

The generated code only sets the header when it is not already present, so values from customHeaders or per-request options always win:

// generated
if (!headers.has('Accept')) {
    headers = headers.set('Accept', 'application/vnd.users+json;version=1.0');
}

Set emitAcceptHeader: false to restore the previous behavior of sending no Accept header.

Usage

// openapi.config.ts
import { GeneratorConfig } from 'ng-openapi';

const config: GeneratorConfig = {
  options: {
    emitAcceptHeader: false, // opt out of the spec-derived Accept header
  },
  ... // other configurations
};

export default config;
