(PHP ActiveX) OneDrive -- List Large DirectoryDemonstrates how to get the entire collection of DriveItem children when the collection is large and multiple pages need to be requested. To test this example, I created a DriveItem with 450 children. Note: This example requires Chilkat v9.5.0.68 or greater.
<?php // This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. $http = new COM("Chilkat_9_5_0.Http"); // Use your previously obtained access token here: // See the following examples for getting an access token: // Get Microsoft Graph OAuth2 Access Token (Azure AD v2.0 Endpoint). // Get Microsoft Graph OAuth2 Access Token (Azure AD Endpoint). // Refresh Access Token (Azure AD v2.0 Endpoint). // Refresh Access Token (Azure AD Endpoint). // (Make sure your token was obtained with the FilesRead or Files.ReadWrite scope.) $http->AuthToken = 'MICROSOFT_GRAPH_ACCESS_TOKEN'; // This example will get the DriveItems in /lots-of-files, which has 450 children.. $http->SetUrlVar('item_path','/lots-of-files'); $json = new COM("Chilkat_9_5_0.JsonObject"); $json->EmitCompact = 0; // This loop will download DriveItems in sets of 50 until no more exist. $bGetMore = 1; // (Add the $top query parameter to define the page size, i.e. the max number of results to return). $nextLink = 'https://graph.microsoft.com/v1.0/me/drive/root:{$item_path}:/children?$top=50'; while (($bGetMore == 1)) { // Get the next chunk of DriveItems $resp = $http->quickGetStr($nextLink); if ($http->LastMethodSuccess != 1) { print $http->LastErrorText . "\n"; exit; } // The response should be JSON. $json->Load($resp); // A successful response should return a status code of 200. if ($http->LastStatus != 200) { print $json->emit() . "\n"; print 'Response status = ' . $http->LastStatus . "\n"; exit; } // Iterate over the DriveItems in the JSON response: $i = 0; $numItems = $json->SizeOfArray('value'); while ($i < $numItems) { $json->I = $i; print 'name: ' . $json->stringOf('value[i].name') . "\n"; $i = $i + 1; } // If a nextLink was included in the JSON, use it to get the next set of 50 DriveItems. // Otherwise, exit the loop. if ($json->HasMember('\'@odata.nextLink\'') == 1) { $nextLink = $json->stringOf('\'@odata.nextLink\''); print 'nextLink: ' . $nextLink . "\n"; } else { $bGetMore = 0; } } ?> |
