rust-epoll-example

async-rust 中 epoll server example 章节的源代码。

Run Server

克隆：

git clone https://github.com/night-cruise/rust-epoll-example.git

切换到项目目录：

cd rust-epoll-example

使用 Cargo 运行项目：

cargo run

然后我们就可以发送 HTTP 请求到 http://127.0.0.1:8000 了。

Send Request

编写一个 Python 小脚本，使用多线程循环发送 HTTP 请求：

import requests

from threading import Thread

with open('image.jpeg', 'rb') as f:
    FILE = f.read()


# send request to http://127.0.0.1:8000
def send_request(host, port):
    for _ in range(100):
        r = requests.post(f"http://{host}:{port}", data={'file': FILE})
        print(f"Receive response: '{r.text}' from {r.url}")


if __name__ == '__main__':
    t_lst = []
    for _ in range(4):
        t = Thread(target=send_request, args=('127.0.0.1', 8000))
        t_lst.append(t)
        t.start()

    for t in t_lst:
        t.join()

server 端的输出：

.....
.....
requests in flight: 3
requests in flight: 3
requests in flight: 3
requests in flight: 3
requests in flight: 3
requests in flight: 3
requests in flight: 3
requests in flight: 3
requests in flight: 3
requests in flight: 3
requests in flight: 3
got all data: 9379840 bytes
requests in flight: 3
answered from request 195

正如我们所看到的那样，server 在同时处理多个请求！
