Send a REST Request using StringBuilder Bodies

See more REST Examples

Demonstrates Rest.FullRequestSb, which sends a complete request whose text body is read from a StringBuilder and stores the text response body in a second StringBuilder.

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

async function chilkatExample() {
  const rest = new Rest();
  const bTls = true;
  const bAutoReconnect = true;
  try {
    await rest.connectAsync('example.com', 443, bTls, bAutoReconnect);
  } catch {
    console.log(rest.lastErrorText);
    return;
  }

  // FullRequestSb sends a request whose text body is read from a StringBuilder and stores the text
  // response body in a second StringBuilder.  This avoids extra string conversions for large bodies.
  const sbRequest = new StringBuilder();
  sbRequest.append('{ "query": "chilkat" }');

  rest.addHeader('Content-Type', 'application/json');

  const sbResponse = new StringBuilder();
  try {
    await rest.fullRequestSbAsync('POST', '/api/search', sbRequest, sbResponse);
  } catch {
    console.log(rest.lastErrorText);
    return;
  }

  let responseText: string;
  try {
    responseText = sbResponse.getAsString();
  } catch {
    console.log(sbResponse.lastErrorText);
    return;
  }

  console.log(responseText);
}
