谷歌驱动器api文件下载。 WebcontentLink为NULL

Question

I am trying to download a file via google api. I came across that I need to retrive a webContentLink but unfortunetly this property is st

This is my code a part of my code:

$service = new Google_Service_Drive($client);

// Print the names and IDs for up to 10 files.
$optParams = array(
  'pageSize' => 1,
  'fields' => 'nextPageToken, files(id, name)'
);
$results = $service->files->listFiles($optParams);

$zdjecie = '/home/bachus03/domains/bachus03.vot.pl/public_html/fb/public/test.jpg';

if (count($results->getFiles()) == 0) {
  print "No files found.
";
} else {
  print "Files:
";
  foreach ($results->getFiles() as $file) {
    printf("%s (%s)
", $file->getName(), $file->getId());
    $file_full = $service->files->get($file->getId());
    /*printFile($service, $file_full);
    file_put_contents($zdjecie, $file_content);
    print "zapisano zdjecie"; */
    var_dump($file_full);
  }

and this is what I get in output:

[bachus03@s14:: ~ ]:$ /usr/local/php/p56/bin/php /home/bachus03/domains/bachus03.vot.pl/public_html/fb/public/quickstart.php

What a i am doing wrong ?

Answer 1

The other main part is you will have to do a files.get request from the id returned in the files.insert call - you will not be able to do it in a single API call on just the insert.

webContentLink can be accessed once the Files resource were retrieve (ie, using get). Based on the documentation. Insert should be able to have webContentLink as well since it also uses Files resources for its response
