原文摘录

摘自原文(1340 字符中的一小部分)
I do not see the end_to_end_encryption app listed here. But since you advertise it big on your website and in communication. And the clients (that also support it are covered) I assume this is part of the program as well.
原文中的代码
curl -u user1:user -X POST https://SERVER/ocs/v2.php/apps/end_to_end_encryption/api/v1/lock/332 -X POST  -H 'OCS-APIREQUEST: true' -H 'user-agent: Mozilla/5.0 (Android) Nextcloud-android/3.13.1'
