Class HTTPClient

Object

dw.net.HTTPClient

The HTTPClient class supports the HTTP methods GET, POST, HEAD, PUT, PATCH, OPTIONS, and DELETE. If a secure connection via HTTPS is established the used server certificate or the signing CAs certificate needs to be imported into the customer key store via Business Manager. Note: when this class is used with sensitive data, be careful in persisting sensitive information. Key selection for mutual TLS:

Check if there is an explicit identity requested setIdentity(KeyRef)
Else, Check if there is a mapping for hostname in the keystore
Deprecated: Select an arbitrary private key from the keystore

 
 var httpClient : HTTPClient = new HTTPClient();
 var message : String;
 httpClient.open('GET', 'http://www.myinstance.com/feed.xml');
 httpClient.setTimeout(3000);
 httpClient.send();
 if (httpClient.statusCode == 200)
 {
      message = httpClient.text;
 }
 else
 {
     // error handling
     message="An error occurred with status code "+httpClient.statusCode;
 }
