谷歌-api-php-客户端 - 驱动器 - 文件插入 - 创建文本文件 - 未添加的内容

Question

我想创建一个纯/文本哑剧类型文件，使用PHP和谷歌应用程序引擎上的谷歌驱动器的谷歌API。

当我使用：

'mimeType' => 'text/plain',

没有内容写入文件。

如果我使用:

'mimeType' => 'application/octet-stream',
'uploadType' => 'media'

内容将添加到文件中。

这段代码来自Google文档：

显示“文本/纯”类型的 mime 类型的代码行

'mimeType' => 'text/plain',

但是，同样，如果我使用它，则不会向文件中添加任何内容。创建纯文本文件和添加内容的设置是什么？

我的完整代码是这样的：

<?php
/* You can NOT see the files created in a Service Account without doing some special stuff.  You need to set some kind
of permissions, and then you can see the files in your SHARED WITH ME section of Google Drive

若您想要一个具有该MIME类型的文本文件，请从PHP创建，而不是直接在驱动器上创建。这就是为什么模仿类型没有被识别。fopen（）可以做到这一点。
