How to destroy the current user session from rails through graphql mutation
问题
我正在尝试通过一个GraphQL变更来清除用户会话，该变更接受user_id作为参数，并销毁用户会话并发送一条消息，该消息将由前端用于注销。
argument :user_id, ID, required: true
field :message, String, null: true
def resolve(user_id:)
user = User.find_by(id: user_id)
raise GraphQL::ExecutionError, 'User not found.' unless user.present?
destroy_user_session(user_id)
user.save!
{ message: 'User session cleared'}
end
private
def destroy_user_session(user_id)
binding.pry
session = context[:session]
session.clear
raise GraphQL::ExecutionError, 'Failed to clear session.' unless session.empty?
end
但问题是，这里用户会话未能正确销毁。我在localhost:3000/api/graphql上测试它，首先调用变更，然后调用一些其他查询，这些查询在用户登录后可访问，不幸的是，两者都被调用了，而不是抛出“需要授权”的错误。我尝试了来自不同网站的几个步骤，但仍然卡在这里。
英文:
I am trying to clear user sessions through a graphql mutation which takes user_id as an argument and destroys the user session and sends a message, which will further be used by frontend to sign out.
argument :user_id, ID, required: true
field :message, String, null: true
def resolve(user_id:)
user = User.find_by(id: user_id)
raise GraphQL::ExecutionError, 'User not found.' unless user.present?
destroy_user_session(user_id)
user.save!
{ message: 'User session cleared'}
end
private
def destroy_user_session(user_id)
binding.pry
session = context[:session]
session.clear
raise GraphQL::ExecutionError, 'Failed to clear session.' unless session.empty?
end
end
But the problem is, the user session is not getting destroyed properly here. I am testing it using localhost:3000/api/graphql where I call the mutation first and then calls some other query that are accessible once the user is logged in and unfortunately both are being called instead of throwing error like authorization is requried. I tried several steps from different sites but still got stuck here.

由于你的graphql_controller继承自application_controller，如果你正在使用devise，你应该可以访问sign_out方法，因此如果你尝试调用context[:controller].sign_out，它应该可以工作。
def destroy_user_session(user_id)
context[:controller].sign_out
session = context[:session]
session.clear
raise GraphQL::ExecutionError, 'Failed to clear session.' unless session.empty?
end
英文:
Since your graphql_controller is inheriting from application_controller you should have access to sign_out method if you are using devise so if you try calling context[:controller].sign_out it should work
def destroy_user_session(user_id)
context[:controller].sign_out
session = context[:session]
session.clear
raise GraphQL::ExecutionError, 'Failed to clear session.' unless session.empty?
end

以下是翻译好的部分：
def destroy_user_session
context[:controller].sign_out
end
以上代码足够。无需进一步编写。（对Nirajan的回答的后续回答）
英文:
def destroy_user_session
context[:controller].sign_out
end
Above code would suffice. You need not to write any further. (Follow up answer for Nirajan's answer)
