Adapter to use hiredis with async connections inside a nginx module

redis_nginx_adapter

An adapter to use the events structure from Nginx on communication with redis, using redis asynchronous context. It requires hiredis >= 0.11.0, and Nginx headers.

Installation

• get Nginx source and configure it with ./configure
• get hiredis source, configure and install it
• configure redis_nginx_adapter pointing to nginx source dir and hiredis like ./configure --with-nginx-dir=../nginx-1.7.1 --with-hiredis-dir=/opt --with-openssl-dir=/usr/local/opt/openssl make make install

Basic usage

Without authentication

redis_nginx_init();
redisAsyncContext *redis_server = NULL;
if (redis_nginx_open_context((const char *) "localhost", 6379, 0, NULL, &redis_server) != NULL) {
    redisAsyncCommand(redis_server, NULL, NULL, "SET %b %d-%d", r->uri.data, r->uri.len, r->headers_out.status, r->headers_out.content_length_n);
}
redis_nginx_close_context(&redis_server);

With authentication

redis_nginx_init();
redisAsyncContext *redis_server = NULL;
if (redis_nginx_open_context((const char *) "localhost", 6379, 0, (const char*) "password", &redis_server) != NULL) {
    redisAsyncCommand(redis_server, NULL, NULL, "SET %b %d-%d", r->uri.data, r->uri.len, r->headers_out.status, r->headers_out.content_length_n);
}
redis_nginx_close_context(&redis_server);

Example

At the example/module folder there is a very basic Nginx module that uses the library. And a Dockerfile that demonstrate how to build and run it.
