Downloads a text file (such as XML, JSON, plain-text, HTML, etc.) into a StringBuilder object.

Note: This example requires Chilkat v9.5.0.97 or greater.

Rust

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// This example uses the OAuth client credentials flow.
// See How to Create an Azure App Registration for OAuth 2.0 Client Credentials

// Use your client ID, client secret, and tenant ID in the following lines
let json = chilkat::JsonObject::new();
