DVLA Vehicle Enquiry Service

See more _Miscellaneous_ Examples

Demonstrates how to make a call to the DVLA Vehicle Enquiry API to get vehicle details of a specified vehicle. It uses the vehicle registration number as input to search and provide details of the vehicle. Rust

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

let http = chilkat::Http::new();

// Implements the following CURL command:

// curl -X POST https://driver-vehicle-licensing.api.gov.uk/vehicle-enquiry/v1/vehicles \
//   -H "x-api-key: supplied API key" \
//   -H "Accept: application/json" \
//   -d '{"registrationNumber": "ABC1234"}'

// Use the following online tool to generate HTTP code from a CURL command
// Convert a cURL Command to HTTP Source Code

// Use this online tool to generate code from sample JSON:
// Generate Code to Create JSON

// The following JSON is sent in the request body.

// {
//   "registrationNumber": "ABC1234"
// }

let json = chilkat::JsonObject::new();
let _ = json.update_string("registrationNumber", "ABC1234");

http.set_request_header("Accept", "application/json");
http.set_request_header("x-api-key", "supplied API key");

    println!("{}", http.last_error_text());
    return;
}

let sb_response_body = chilkat::StringBuilder::new();
let _ = resp.get_body_sb(&sb_response_body);
let j_resp = chilkat::JsonObject::new();
let _ = j_resp.load_sb(&sb_response_body);
