lua-resty-http-fast
Note: OpenResty 1.21.4.3 or higher is required for this library.
The repository of the binary installer
First, we need to configure the repository of the binary installer using the commands below. (The CLIENT_TOKEN in the commands needs to be replaced with a valid Token from the subscription email)
curl -o get-xray-priv-lib-repo.sh https://pkg2.openresty.com/scripts/get-xray-priv-lib-repo.sh
sudo bash get-xray-priv-lib-repo.sh -l coro-nginx-module -t CLIENT_TOKEN
sudo bash get-xray-priv-lib-repo.sh -l lua-resty-http-fast -t CLIENT_TOKEN

Usage
Nginx configuration
Before you can use lua-resty-http-fast, you need to add the following configuration items to the configuration file nginx.conf to load the related dynamic modules.
# The load_module directive must be on top of nginx.conf
load_module "/usr/local/openresty-coro-nginx-module/lib/ngx_http_coro_module.so";
load_module "/usr/local/openresty-coro-nginx-module/lib/ngx_http_coro_libcurl_module.so";
...
http {
coro_preload /usr/local/openresty/openssl111/lib/libcrypto.so;
coro_preload /usr/local/openresty/openssl111/lib/libssl.so;
coro_preload /usr/local/openresty/libcurl/lib/libcurl.so;
coro_stack_size 65536;
lua_package_path "/usr/local/openresty/site/lualib/?.ljbc;;";
...
}
Lua interfaces
The Lua interfaces of this library are basically consistent with the open source library lua-resty-http.
For full usage of lua-resty-http-fast, see the official documentation.
Here are some examples of usage:
Simple HTTP request
# The load_module directive must be on top of nginx.conf
load_module "/usr/local/openresty-coro-nginx-module/lib/ngx_http_coro_module.so";
load_module "/usr/local/openresty-coro-nginx-module/lib/ngx_http_coro_libcurl_module.so";
...
http {
coro_preload /usr/local/openresty/openssl111/lib/libcrypto.so;
coro_preload /usr/local/openresty/openssl111/lib/libssl.so;
coro_preload /usr/local/openresty/libcurl/lib/libcurl.so;
coro_stack_size 65536;
lua_package_path "/usr/local/openresty/site/lualib/?.ljbc;;";
server {
location /a {
# need to specify the resolver to resolve the hostname
resolver 8.8.8.8;
content_by_lua_block {
local http = require "resty.http.fast"
local httpc = http.new()
httpc:connect{
scheme = "http",
host = "127.0.0.1",
port = ngx.var.server_port
}
local res, err = httpc:request{
path = "/b"
}
ngx.status = res.status
ngx.print(res:read_body())
httpc:close()
}
}
location = /b {
echo "OK";
}
}
}
HTTPS request using mTLS
# The load_module directive must be on top of nginx.conf
load_module "/usr/local/openresty-coro-nginx-module/lib/ngx_http_coro_module.so";
load_module "/usr/local/openresty-coro-nginx-module/lib/ngx_http_coro_libcurl_module.so";
...
