Google 驱动器 API PHP - 更新 txt 文件的内容

Question

我创建了一个文件夹，并在该文件夹中创建了 2 个文本文件，其中包含一些文本。我还可以毫无问题地列出文件并获取其中的文本。现在我正在尝试更新该文件中的文本，但我总是收到此错误：

"domain": "global",
"reason": "fieldNotWritable",
"message": "The resource body includes fields which are not directly writable."

我创建了一个类似于 https://developers.google.com/drive/v2/reference/files/update 中介绍的函数。

我使用这个例子是因为在 v3 版本中，Google 没有提供任何例子，而且我找不到任何可以帮助我的东西。我的功能如下。

function updateFile ($service, $fileId, $newTitle, $newDescription, $newMimeType, $text) {
    try {
        // First retrieve the file from the API.
        $file = $service->files->get($fileId);

        // File's new metadata.
        $file->setName($newTitle);
        $file->setDescription($newDescription);
        $file->setMimeType($newMimeType);

        // File's new content.
        $additionalParams = array(
            'data' => $text,
            'uploadType' => 'media'
        );

        // Send the request to the API.
        $updatedFile = $service->files->update($fileId, $file, $additionalParams);
        return $updatedFile;
    } catch (Exception $e) {
        print "An error occurred: " . $e->getMessage();
    }
}

提前致谢。

基于此，在 v3 上，像这样使用 update 会引发错误 fieldNotWritable。

The solution is to create an empty File setting only the new values:
File newContent = new File();
newContent.setTrashed(true);
service.files().update(fileId, newContent).execute();
Note: File refers to com.google.api.services.drive.model.File (it is not java.io.File).

另外，基于此documentation, you can see that shared isn't a writable field. You can share a file by adding a new permission, and you can check if a file has been shared by reading the shared property. But saying a file is shared, other than by actually sharing it, makes no sense.
