Hi,

I'm trying to override Content-Type response header by using:

header_filter_by_lua 'ngx.header.content_type = "text/html"';

However the charset is not being replaced and stays in the response.

How can I set/remove charset in Content-Type header?

Thanks!

Your example seems fine:

root@soter:/usr/local/openresty/nginx# grep default_type conf/nginx.conf

default_type text/plain;

root@soter:/usr/local/openresty/nginx# cat conf/nginx.conf

[...snip...]

location /html-test {

content_by_lua 'ngx.say("<html><head><title>Hello</title></head><body>Hello, world!</body></html>")';

header_filter_by_lua 'ngx.header.content_type = "text/html"';

}

poprocks@soter:~$ curl localhost/html-test

<html><head><title>Hello</title></head><body>Hello, world!</body></html>

poprocks@soter:~$ curl -I localhost/html-test

HTTP/1.1 200 OK

Server: openresty/1.9.7.4

Date: Fri, 08 Apr 2016 01:31:11 GMT

Content-Type: text/html

Connection: keep-alive

Can you post a full, reproducible example of your configuration>

The header is Content-Type: text/html;charset=XXX

After it is replaced, it becomes

Content-Type: text/html; charset=XXX

If I force charset

header_filter_by_lua 'ngx.header.content_type = "text/html; charset=UTF-8"';

it becomes

Content-Type: text/html; charset=UTF-8; charset=XXX

Thanks!

Sorry, your example isn't particularly clear. Can you please post a simple example of your -entire- config file, not just snippets, so we can examine the problem? Also note that "charset" is relatively meaningless in this context. We will care only about the entire contents of the Content-Type header. Thanks!

Hello!

See the standard "charset" directive of nginx:
