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. Node.js

function chilkatExample() {

    var success = false;

    //  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"

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

    //  Build the JSON that provides information for getting the OAuth2 access token using the OAuth2 client credentials flow.
    var jsonOAuth2 = new chilkat.JsonObject();

    jsonOAuth2.UpdateString("oauth2.client_id","CLIENT_ID");
    jsonOAuth2.UpdateString("oauth2.client_secret","CLIENT_SECRET");
    jsonOAuth2.UpdateString("oauth2.scope","https://graph.microsoft.com/.default");
    jsonOAuth2.UpdateString("oauth2.token_endpoint","https://login.microsoftonline.com/TENANT_ID/oauth2/v2.0/token");

    var httpCurl = new chilkat.HttpCurl();

    //  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.
    httpCurl.SetAuth(jsonOAuth2);

    //  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:
    httpCurl.SetVar("sharepoint_hostname","example.sharepoint.com");
    httpCurl.SetVar("site_name","test");

    //  Run the curl command.
    success = httpCurl.DoYourThing(sb.GetAsString());
    if (success == false) {
        console.log(httpCurl.LastErrorText);
        return;
    }

    var responseJson = new chilkat.JsonObject();
    responseJson.EmitCompact = false;

    httpCurl.GetResponseJson(responseJson);

    var statusCode = httpCurl.StatusCode;
    console.log("response status code: " + statusCode);

    console.log(responseJson.Emit());
