List policies: JavaScript example

Use the following steps to run the example.

  1. Create a file named FirstStepsGetExample.js and copy the following example code to the file. 
    exports.getPolicies = function(hostNameAndPort, apiSecretKey) {
  return new Promise((resolve, reject) => {
    // Deep Security module
    const api = require("@trendmicro/deepsecurity");

    // Create the client
    const defaultClient = api.ApiClient.instance;
    defaultClient.basePath = "https:// " + hostNameAndPort + "/api";
    const defaultAuthentication = defaultClient.authentications["DefaultAuthentication"];
    defaultAuthentication.apiKey = apiSecretKey;

    // Allow connection that is 'secured' with self-signed certificate - for development only
    process.env.NODE_TLS_REJECT_UNAUTHORIZED = "0";

    // Create a PoliciesApi object
    const policiesApi = new api.PoliciesApi();

    // List policies. Use version v1 of the API
    policiesApi.listPolicies("v1")
      .then(policies => {
        resolve(policies);
      })
      .catch(error => {
        reject(error);
      });
  });
};
  2. Create another file named App.js and copy the following code to the file: 
    const path = require("path");

const FirstStepsGetExample = require(path.resolve(__dirname, "./FirstStepsGetExample.js"));

FirstStepsGetExample.getPolicies("localhost:4119", "3:zNi5ag8xPGpfEMElV0GxAIpTs5Ji8BQoCtXaTAgKkVM=")
  .then( policies => {
    console.log(policies);
  })
  .catch(error => {
    console.log(error);
});
  3. In the App.js file, change the URL and secret key parameters of the call to FirstStepsGetExample.getPolicies according to your environment.
  4. Open a Command Prompt (Windows) or terminal (Linux) and enter the following command:

    node App.js

  5. If you are seeing the error TypeError: Cannot read properties of undefined (reading 'text'), it means that the SDK cannot establish a connection between APIClient and the Deep Security Manager (DSM) host. Check that the DSM host name is correct.
