PHP OC_Request::hasModificationTime方法代码示例

 /**
  * Updates the data
  *
  * The data argument is a readable stream resource.
  *
  * After a succesful put operation, you may choose to return an ETag. The
  * etag must always be surrounded by double-quotes. These quotes must
  * appear in the actual string you're returning.
  *
  * Clients may use the ETag from a PUT request to later on make sure that
  * when they update the file, the contents haven't changed in the mean
  * time.
  *
  * If you don't plan to store the file byte-by-byte, and you return a
  * different object on a subsequent GET you are strongly recommended to not
  * return an ETag, and just return null.
  *
  * @param resource $data
  * @throws Sabre_DAV_Exception_Forbidden
  * @return string|null
