fastcgi-client-rs

Fastcgi client implemented for Rust, power by tokio.

Installation

Add dependencies to your Cargo.toml by cargo add:

cargo add tokio --features full
cargo add fastcgi-client

Examples

Short connection mode:

use fastcgi_client::{Client, Params, Request};
use std::env;
use tokio::{io, net::TcpStream};

#[tokio::main]
async fn main() {
    let script_filename = env::current_dir()
        .unwrap()
        .join("tests")
        .join("php")
        .join("index.php");
    let script_filename = script_filename.to_str().unwrap();
    let script_name = "/index.php";

    // Connect to php-fpm default listening address.
    let stream = TcpStream::connect(("127.0.0.1", 9000)).await.unwrap();
    let mut client = Client::new(stream);

    // Fastcgi params, please reference to nginx-php-fpm config.
    let params = Params::default()
        .set_request_method("GET")
        .set_script_name(script_name)
        .set_script_filename(script_filename)
        .set_request_uri(script_name)
        .set_document_uri(script_name)
        .set_remote_addr("127.0.0.1")
        .set_remote_port("12345")
        .set_server_addr("127.0.0.1")
        .set_server_port("80")
        .set_server_name("jmjoy-pc")
        .set_content_type("")
        .set_content_length("0");

    // Fetch fastcgi server(php-fpm) response.
    let output = client.execute_once(Request::new(params, &mut io::empty())).await.unwrap();

    // "Content-type: text/html; charset=UTF-8\r\n\r\nhello"
    let stdout = String::from_utf8(output.get_stdout().unwrap()).unwrap();

    assert!(stdout.contains("Content-type: text/html; charset=UTF-8"));
    assert!(stdout.contains("hello"));
    assert_eq!(output.get_stderr(), None);
}

Keep alive mode:

use fastcgi_client::{Client, Params, Request};
use std::env;
use tokio::{io, net::TcpStream};

#[tokio::main]
async fn main() {
    // Connect to php-fpm default listening address.
    let stream = TcpStream::connect(("127.0.0.1", 9000)).await.unwrap();
    let mut client = Client::new_keep_alive(stream);

    // Fastcgi params, please reference to nginx-php-fpm config.
    let params = Params::default();

    for _ in (0..3) {
        // Fetch fastcgi server(php-fpm) response.
        let output = client.execute(Request::new(params.clone(), &mut io::empty())).await.unwrap();

        // "Content-type: text/html; charset=UTF-8\r\n\r\nhello"
        let stdout = String::from_utf8(output.get_stdout().unwrap()).unwrap();

        assert!(stdout.contains("Content-type: text/html; charset=UTF-8"));
        assert!(stdout.contains("hello"));
        assert_eq!(output.get_stderr(), None);
    }
}
