curl with OAuth2 Client Credentials

See more CURL Examples

This example shows how to run a simple CURL command with an OAuth2 access token for authorization. We use CURL to retrieve a SharePoint site ID, and Chilkat automatically fetches the OAuth2 access token using the provided credentials. Rust

// This example will run the following curl command

// curl -X GET "https://graph.microsoft.com/v1.0/sites/{{sharepoint_hostname}}:/sites/{{site_name}}" \
//   -H "Authorization: Bearer ACCESS_TOKEN" \
//   -H "Accept: application/json"

let sb = chilkat::StringBuilder::new();
let _ = sb.append_ln("curl -X GET \"https://graph.microsoft.com/v1.0/sites/{{sharepoint_hostname}}:/sites/{{site_name}}\" \\");
let _ = sb.append_ln("  -H \"Authorization: Bearer ACCESS_TOKEN\" \\");
let _ = sb.append_ln("  -H \"Accept: application/json\"");

// Build the JSON that provides information for getting the OAuth2 access token using the OAuth2 client credentials flow.
let json_o_auth2 = chilkat::JsonObject::new();

let _ = json_o_auth2.update_string("oauth2.client_id", "CLIENT_ID");
let _ = json_o_auth2.update_string("oauth2.client_secret", "CLIENT_SECRET");
let _ = json_o_auth2.update_string("oauth2.scope", "https://graph.microsoft.com/.default");
let _ = json_o_auth2.update_string("oauth2.token_endpoint", "https://login.microsoftonline.com/TENANT_ID/oauth2/v2.0/token");

let http_curl = chilkat::HttpCurl::new();

// Provide the information for getting the OAuth2 access token from the token endpoint
// Note: The Authorization header specified in the curl command will be ignored and replaced using the OAuth2 access token obtained at runtime from the token endpoint.
let _ = http_curl.set_auth(&json_o_auth2);

// The placeholders {{sharepoint_hostname}} and {{site_name}} represent variables that must be defined before execution.
// When DoYourThing runs the curl command, it automatically substitutes these placeholders with their corresponding values.
// Below are the values assigned to these variables:
http_curl.set_var("sharepoint_hostname", "example.sharepoint.com");
http_curl.set_var("site_name", "test");

// Run the curl command.
if http_curl.do_your_thing(&sb.get_as_string().unwrap_or_default()).is_err() {
    println!("{}", http_curl.last_error_text());
    return;
}

let response_json = chilkat::JsonObject::new();
response_json.set_emit_compact(false);

let _ = http_curl.get_response_json(&response_json);

let status_code = http_curl.status_code();
println!("response status code: {}", status_code);

println!("{}", response_json.emit().unwrap_or_default());
