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. Xojo Plugin

Dim success As Boolean
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"

Dim sb As New Chilkat.StringBuilder
success = sb.AppendLn("curl -X GET ""https://graph.microsoft.com/v1.0/sites/{{sharepoint_hostname}}:/sites/{{site_name}}"" \")
success = sb.AppendLn("  -H ""Authorization: Bearer ACCESS_TOKEN"" \")
success = sb.AppendLn("  -H ""Accept: application/json""")

// Build the JSON that provides information for getting the OAuth2 access token using the OAuth2 client credentials flow.
Dim jsonOAuth2 As New Chilkat.JsonObject

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

Dim httpCurl As 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.
success = 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) Then
    System.DebugLog(httpCurl.LastErrorText)
    Return
End If

Dim responseJson As New Chilkat.JsonObject

success = httpCurl.GetResponseJson(responseJson)

Dim statusCode As Int32
