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. Lianja

llSuccess = .F.

// 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"

loSb = createobject("CkStringBuilder")
loSb.AppendLn('curl -X GET "https://graph.microsoft.com/v1.0/sites/{{sharepoint_hostname}}:/sites/{{site_name}}" \")
loSb.AppendLn('  -H "Authorization: Bearer ACCESS_TOKEN" \")
loSb.AppendLn('  -H "Accept: application/json"')

// 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.
loHttpCurl.SetAuth(loJsonOAuth2)

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

// Run the curl command.
