Client Certificate in REST

See more REST Examples

Demonstrates how to use a client certificate with a REST connection. React Native

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

async function chilkatExample() {
  // This example requires the Chilkat API to have been previously unlocked.
  // See Global Unlock Sample for sample code.

  // This example shows how to use the Chilkat socket object's connection.
  const rest = new Rest();
  const socket = new Socket();

  // Set the certificate to be used for mutual TLS authentication
  // (i.e. sets the client-side certificate for two-way TLS authentication)
  // Note: There are other ways to set the client certificate using Chilkat.
  // For example, on Windows systems, a Chilkat certificate object could be loaded with certificate
  // pre-installed (with private key) in a Windows certificate store, and then socket.SetSslClientCert could be called.
  try {
    socket.setSslClientCertPfx('/home/bob/pfxFiles/myClientSideCertWithPrivateKey.pfx', 'pfxPassword');
  } catch {
    console.log(socket.lastErrorText);
    return;
  }

  // Note: The certificate used for the client-side of TLS mutual authentication
  // must have the associated private key available. (.pfx/.p12 files typically store both
  // the certificate and associated private key.)

  // Establish the connection using the socket object (with client certificate authentication).
  const bTls = true;
  const port = 443;
  const maxWaitMs = 5000;
  try {
    await socket.connectAsync('www.example.com', port, bTls, maxWaitMs);
  } catch {
    console.log(`Connect Failure Error Code: ${socket.connectFailReason}`);
    console.log(socket.lastErrorText);
    return;
  }

  const bAutoReconnect = true;

  // Use the connection:
  try {
    rest.useConnection(socket, bAutoReconnect);
  } catch {
    console.log(rest.lastErrorText);
    return;
  }

  // At this point we are connected and can make REST calls...
  // For example..
  let responseJson: string;
  try {
    responseJson = await rest.fullRequestNoBodyAsync('GET', '/someQuery');
  } catch {
    console.log(rest.lastErrorText);
    return;
  }
