可恢复文件上传

Question

我对新的Google Drive API客户端库的文档存在严重问题。看起来这应该是一个容易回答，而不必把它放在stackoverflow上。我正在认真考虑在这个问题上滚动自己，一个64页的“正常工作”的图书馆到目前为止一直是“头痛”

如何将uploadType设置为“resumable”而不是默认的“simple”。我在图书馆搜索了一种方法，但它似乎不存在。他们唯一的提示是他们的样本上传页面https://developers.google.com/drive/quickstart-php

上的代码

//Insert a file
$file = new Google_DriveFile();
$file->setTitle('My document');
$file->setDescription('A test document');
$file->setMimeType('text/plain');

$data = file_get_contents('document.txt');

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

这里没有设置uploadType ...... ???

他们在另一页上的docs只是将uploadType作为地址的一部分显示为GET：https://www.googleapis.com/upload/drive/v2/files ?uploadType=resumable但是当您使用$service->files->insert时，该库会设置地址

Answer 1

以下示例适用于最新版本的Google API PHP客户端（https://code.google.com/p/google-api-php-client/source/checkout）

if ($client->getAccessToken()) {
  $filePath = "path/to/foo.txt";
  $chunkSizeBytes = 1 * 1024 * 1024;

  $file = new Google_DriveFile();
  $file->setTitle('My document');
  $file->setDescription('A test document');
  $file->setMimeType('text/plain');

  $media = new Google_MediaFileUpload('text/plain', null, true, $chunkSizeBytes);
  $media->setFileSize(filesize($filePath));

  $result = $service->files->insert($file, array('mediaUpload' => $media));

  $status = false;
  $handle = fopen($filePath, "rb");
  while (!$status && !feof($handle)) {
    $chunk = fread($handle, $chunkSizeBytes);
    $uploadStatus = $media->nextChunk($result, $chunk);
  }

  fclose($handle);
}

这可能是较新的参考，但这是Google对此问题的正式看法：https://developers.google.com/api-client-library/php/guide/media_upload

还可以跨多个请求拆分上传。这个方便更大的文件，并允许恢复上传这儿存在一个问题。可以单独发送可恢复的上传元数据。

$file = new Google_Service_Drive_DriveFile();
$file->title = "Big File";
$chunkSizeBytes = 1 * 1024 * 1024;

// Call the API with the media upload, defer so it doesn't immediately return.
$client->setDefer(true);
$request = $service->files->insert($file);

// Create a media file upload to represent our upload process.
$media = new Google_Http_MediaFileUpload(
  $client,
  $request,
  'text/plain',
  null,
  true,
  $chunkSizeBytes
);
$media->setFileSize(filesize("path/to/file"));

// Upload the various chunks. $status will be false until the process is
// complete.
$status = false;
$handle = fopen("path/to/file", "rb");
while (!$status && !feof($handle)) {
  $chunk = fread($handle, $chunkSizeBytes);
  $status = $media->nextChunk($chunk);
 }

// The final value of $status will be the data from the API for the object
// that has been uploaded.
$result = false;
if($status != false) {
  $result = $status;
}

fclose($handle);
// Reset to the client to execute requests immediately in the future.
$client->setDefer(false);
