使用带有PHP的Google Drive API上传图片？

Question

I am trying to upload images with the Google API ( https://github.com/google/google-api-php-client ) and I can't seem to get it working. Whenever I run it it gives me a 401 Login Required error. Here is my code:

Functions:

public function __construct()
{
    $this->instance = new \Google_Client();

    $this->instance->setApplicationName('DPStatsBot');
    $this->instance->setDeveloperKey(Config::getInstance()->getDriveDeveloperKey());
    $this->instance->addScope('https://www.googleapis.com/auth/drive');

    $this->drive_instance = new \Google_Service_Drive($this->instance);
}

public function upload($image, $dpname)
{
    $file = new \Google_Service_Drive_DriveFile();
    $file->setTitle($dpname . '_' . RandomString::string());

    $upload = $this->drive_instance->files->insert($file,
    [
        'data' => $image,
        'mimeType' => 'image/jpg',
        'uploadType' => 'media'
    ]);

    return $upload;
}

Calls to functions:

$client = new DriveClient();

foreach($dm->entities->media as $img)
{
    Printer::write('Recieved image from "' . $dm->sender->screen_name . '", saving to Drive...');

    $client->upload($this->getImage($img->media_url), $dm->sender->screen_name);
}

Error:

Fatal error: Uncaught exception 'Google_Service_Exception' with message 'Error c
alling POST https://www.googleapis.com/upload/drive/v2/files?uploadType=multipar
t&key=APIKEYHERE: (401) Login Required' in C:\Doesp
lay\DPStatsBot\vendor\google\apiclient\src\Google\Http\REST.php:110

The API key I am using is from my Google Developers console under APIs & auth->Credentials and it is a Public API key.

Any help will be greatly appreciated!

Thanks

Edit: DriveClient is the class that contains the functions

The public api key is for public access APIs. Data that is not owned by a user. You need to create client id from web application.

Then you will be able to authenticate it using Oauth2.

this might get you started. drive Quickstart php

How to know when you need to be authenticated:

• Public API: Aanalytics metadata API meta data doesn't belong to any user its public data anyone can access.

• User data API: Google Analytics Real-time Data the data returned is owned by a user, it is not public data viewable by everyone. Documentation states

Requires authorization

If the documentation says requires authentication then you have to be authenticated to access that call.

File Parent

Check the $parentId variable, this is how you upload a file into a specific directory if you don't add setParents it will be uploaded into the root folder. code ripped from

/**
 * Insert new file.
 *
 * @param Google_Service_Drive $service Drive API service instance.
 * @param string $title Title of the file to insert, including the extension.
 * @param string $description Description of the file to insert.
 * @param string $parentId Parent folder's ID.
 * @param string $mimeType MIME type of the file to insert.
 * @param string $filename Filename of the file to insert.
 * @return Google_Service_Drive_DriveFile The file that was inserted. NULL is
 *     returned if an API error occurred.
 */
function insertFile($service, $title, $description, $parentId, $mimeType, $filename) {
  $file = new Google_Service_Drive_DriveFile();
  $file->setTitle($title);
  $file->setDescription($description);
  $file->setMimeType($mimeType);

  // Set the parent folder.
  if ($parentId != null) {
    $parent = new Google_Service_Drive_ParentReference();
    $parent->setId($parentId);
    $file->setParents(array($parent));
  }

  try {
    $data = file_get_contents($filename);

    $createdFile = $service->files->insert($file, array(
      'data' => $data,
      'mimeType' => $mimeType,
    ));

    // Uncomment the following line to print the File ID
    // print 'File ID: %s' % $createdFile->getId();

    return $createdFile;
  } catch (Exception $e) {
    print "An error occurred: " . $e->getMessage();
  }
}
