Add a Request Header to a REST Request

See more REST Examples

Demonstrates Rest.AddHeader, which adds an HTTP request header field. The 1st argument is the field name and the 2nd is the value. Adding a header whose name already exists replaces the previous value.

import { Rest } from '@chilkat/react-native'

async function chilkatExample() {
  const rest = new Rest();

  // Connect to the REST server.  The 3rd argument enables TLS (use true for HTTPS on port 443),
  // and the 4th enables automatic reconnection if the connection is dropped between requests.
  const bTls = true;
  const bAutoReconnect = true;
  try {
    await rest.connectAsync('example.com', 443, bTls, bAutoReconnect);
  } catch {
    console.log(rest.lastErrorText);
    return;
  }

  // Add request header fields.  The 1st argument is the field name and the 2nd is the value.
  // Adding a header with a name that already exists replaces the previous value.
  rest.addHeader('Accept', 'application/json');
  rest.addHeader('X-Custom-Header', 'example-value');

  let responseText: string;
  try {
    responseText = await rest.fullRequestNoBodyAsync('GET', '/api/data');
  } catch {
    console.log(rest.lastErrorText);
    return;
  }

  console.log(responseText);
