Export to PDF On-Premises REST API usage

The Export to PDF On-Premises converter provides the ability to convert an HTML document to a PDF file via Restful API.

The API is available on http://localhost:[port] (by default the port is 8080).

The REST API documentation is available at http://localhost:[port]/docs.
Alternatively, you can check the specifications in our public resources https://pdf-converter.cke-cs.com/docs.

If you have the authorization for the API enabled, you should provide an authorization token. More instructions you can find in the authorization section.

# Using additional HTTP headers

If fetching some resources (e.g. images) used in a generated PDF requires passing an additional authorization factor in the form of additional HTTP headers:

It can be defined on the application startup by setting EXTRA_HTTP_HEADERS environmental variable where the value is a stringified JSON object with required headers.
It can be defined in a request sent to the PDF Converter API in options:

const data = {
   html: '<p>I am a teapot</p><img src="https://secured-example-website.com/image.jpg">',
   css: 'p { color: red; }',
   options: {
      extra_http_headers: {
        authorization: 'Bearer RDp0NqyePooNWFIWvHtbKrKKHLXfmLfZcv3PRpCyJI90uwi3pKvumKl2vymCxoGFw6Vx'
      }
   }
};

axios.post( 'https://pdf-converter.cke-cs.com/v1/convert', data, config )
   .then( response => {
      fs.writeFileSync('./file.pdf', response.data, 'binary')
   } ).catch( error => {
      console.log( error );
   } );

Headers defined in the application config and from the request are merged. If the same header is defined in both places, a header value from PDF options is prioritized over the value from the application config.
