示例1: _uploadFileChunked
/**
* @param string $path
*
* @param WriteMode $writeMode
* What to do if there's already a file at the given path (UTF-8).
*
* @param resource $inStream
* The source of data to upload.
*
* @param int|null $numBytes
* You can pass in <code>null</code>. But if you know how many bytes you expect, pass in
* that value and this function will do a sanity check at the end to make sure the number of
* bytes read from $inStream matches up.
*
* @param int $chunkSize
*
* @return array
* The <a href="https://www.dropbox.com/developers/core/docs#metadata-details>metadata
* object</a> for the newly-added file.
