为什么我不能设置多个Cookie [英] How come I cannot set multiple cookies

问题描述

我正在尝试设置多个cookie，但是它不起作用:

I'm trying to set multiple cookies, but it's not working:

if type(ngx.header["Set-Cookie"]) ~= "table" then
    ngx.header["Set-Cookie"] = {}
end
table.insert(ngx.header["Set-Cookie"], "Cookie1=abc; Path=/")
table.insert(ngx.header["Set-Cookie"], "Cookie2=def; Path=/")
table.insert(ngx.header["Set-Cookie"], "Cookie3=ghi; Path=/")

在客户端上，我没有收到任何Cookie.

On the client I do not receive any cookies.

推荐答案

ngx.header["Set-Cookie"]是一个特殊的表，每次修改表时都必须将其重新分配给新表(从表中插入或删除的元素对将发送给客户端的Cookie):

ngx.header["Set-Cookie"] is a special table, and must be reassigned to with a new table every time you modify it (elements inserted or removed from it have no effect on the cookies that will be sent to the client):

if type(ngx.header["Set-Cookie"]) == "table" then
    ngx.header["Set-Cookie"] = { "AnotherCookieValue=abc; Path=/", unpack(ngx.header["Set-Cookie"]) }
else
    ngx.header["Set-Cookie"] = { "AnotherCookieValue=abc; Path=/", ngx.header["Set-Cookie"] }
end
