最近把seafile服务升级到了11版本，但是登录后出现如下错误：

Forbidden (403)

CSRF verification failed. Request aborted.

首先修改/conf/seahub_settings.py，加入DEBUG = True，看看是什么错误。打开后重启seafile的docker容器，再次访问出现如下提示：

Help

Reason given for failure:

    Origin checking failed - http://xxx.com does not match any trusted origins.
    

In general, this can occur when there is a genuine Cross Site Request Forgery, or when Django’s CSRF mechanism has not been used correctly. For POST forms, you need to ensure:

• Your browser is accepting cookies.

• The view function passes a request to the template’s render method.

• In the template, there is a {% csrf_token %} template tag inside each POST form that targets an internal URL.

• If you are not using CsrfViewMiddleware, then you must use csrf_protect on any views that use the csrf_token template tag, as well as those that accept the POST data.

• The form has a valid CSRF token. After logging in in another browser tab or hitting the back button after a login, you may need to reload the page with the form, because the token is rotated after a login.

You’re seeing the help section of this page because you have DEBUG = True in your Django settings file. Change that to False, and only the initial error message will be displayed.

You can customize this page using the CSRF_FAILURE_VIEW setting.

修改/conf/seahub_settings.py，加入如下配置即可:

CSRF_TRUSTED_ORIGINS = ["http://xxx.com"]
