[GitHub] [apisix] Marco-Zheng opened a new issue #4318: request help: Set reuquest var in header, but i don't get param from ctx.var
Marco-Zheng opened a new issue #4318:
URL: https://github.com/apache/apisix/issues/4318
### Issue description
I see that in the traffic-split of the official case of Apisix, ctx.var is the value from the request header, but when I put the parameter in the header when I requested it, I didn't get the value ?
### Environment
* apisix version (cmd: `apisix version`): 2.4

The request header information will not be stored in ctx.var unless we store it in advance. The request header is obtained by using nginx's `$http_PARAMETER` method.

Hi @Marco-Zheng, here we override the index function.

Not really true. Here we override the index function.

like @Firstsawyou said, with `ctx.var` you can't just rely on dynamic debug to see what values are in it, there is even a portion of c data in this.
