leehomewl opened a new issue #1120: set variable inoperative!!
URL: https://github.com/apache/incubator-apisix/issues/1120
Hi:
我开发一个插件， 我在 bin/apisix 中加入初始化变量，我发现一个奇怪的问题：
如果 我设置这个变量为为空的时候
location / {
......
set $skip '';
......
}
我可以在插件 /lua/apisix/plugins目录下通过下面的rewrite阶段去修改这个变量， 并且后面的服务可以用到修改后的值。 是正常的
function _M.rewrite(conf, ctx)
ngx_var.skip = 0
end
但如果我改成下面的情况， 初始化这个值得时候设置为1 ，此时，我的插件就不其作用了，修改后的值似乎没有生效， 我测试了很多遍， 一直无法解决。 能帮忙确认下是什么原因吗？
location / {
......
set $skip 1 ;
......
}

我打算加入 srcache-nginx-module的模块进来， 我在openresty 上 用rewrite_by_lua 就非常正常。
但是我在 apisix 上使用的 插件的plugins 的rewrite 就无法成功， 每次赋值都好像执行阶段顺序没有对， 有遇到这种类似的情况的吼一下，谢谢
下面是openresty 正常的写法， 都是ok的。
location /test_foo {
set $key $uri$args;
srcache_fetch GET /memc $key;
srcache_store PUT /memc $key;
srcache_store_statuses 200 301 302;
set $fetch_skip '1';
set $store_skip '1';
rewrite_by_lua '
ngx.var.fetch_skip = 0
ngx.var.store_skip = 0
';
srcache_fetch_skip $fetch_skip;
srcache_store_skip $store_skip;
proxy_pass http://192.168.12.148:81;

The apisix run both ".access" and ".rewrite" in the "access" phase.

好的，明白了， 我的修改是 set_by_lua 和 rewrite_by_lua 2个执行阶段的，所以在access就无效了。
谢谢哈。
