请参见政策文件条件.但是，这对其他上传机制没有帮助，因此您必须采用其他方式(也许是 Cloud Function ，它会在上传时检查内容类型并删除违规者.
See policy document conditions for form POSTs. This won't help with other upload mechanisms, however, so you'll have to do that some other way (maybe a Cloud Function that does a content type check on upload and deletes violators).
