在Linux系统中,Socket.5并不是一个标准的协议

  1. 安装libevent库:
sudo apt-get update
sudo apt-get install libevent-dev
  1. 安装libev库:
sudo apt-get install libev-dev
  1. 编写一个简单的Socket.5服务器和客户端示例:

服务器端(server.c):

#include <arpa/inet.h>
#include <netinet/in.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <sys/socket.h>
#include <unistd.h>
#include <event2/event.h>
#include <event2/http.h>

static void cb(evutil_socket_t fd, short events, void *arg) {
    struct evhttp *http = (struct evhttp *)arg;
    struct evhttp_request *req = evhttp_request_new(NULL, NULL);
    if (!req) {
        fprintf(stderr, "Could not allocate request\n");
        return;
    }

    evhttp_add_header(req->output_headers, "Content-Type", "text/plain");
    evhttp_add_header(req->output_headers, "Connection", "close");
    evhttp_send_reply(req, HTTP_OK, "Hello, Socket.5!", NULL);
    evhttp_free(req);
}

int main() {
    struct event_base *base = event_base_new();
    if (!base) {
        fprintf(stderr, "Could not create event base\n");
        return 1;
    }

    struct evhttp *http = evhttp_new(base);
    if (!http) {
        fprintf(stderr, "Could not create HTTP server\n");
        return 1;
    }

    evhttp_set_gencb(http, cb, NULL);
    evhttp_bind_socket(http, "0.0.0.0:8080", NULL);

    event_base_dispatch(base);

    evhttp_free(http);
    event_base_free(base);

    return 0;
}

客户端(client.c):

#include <arpa/inet.h>
#include <netinet/in.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <sys/socket.h>
#include <unistd.h>
#include <event2/event.h>
#include <event2/http.h>

static void cb(struct evhttp_request *req, void *arg) {
    char *buf = malloc(1024);
    if (!buf) {
        fprintf(stderr, "Could not allocate buffer\n");
        return;
    }

    ssize_t len = evhttp_read(req, buf, 1023);
    if (len != -1) {
        buf[len] = '\0';
        printf("Received: %s\n", buf);
    } else {
        perror("evhttp_read");
    }

    free(buf);
    evhttp_free(req);
}

int main() {
    struct event_base *base = event_base_new();
    if (!base) {
        fprintf(stderr, "Could not create event base\n");
        return 1;
    }

    struct evhttp *http = evhttp_new(base);
    if (!http) {
        fprintf(stderr, "Could not create HTTP client\n");
        return 1;
    }

    struct evhttp_request *req = evhttp_request_new(HTTP_GET, "/");
    if (!req) {
        fprintf(stderr, "Could not allocate request\n");
        return 1;
    }

    evhttp_add_header(req->output_headers, "Host", "localhost");

    evhttp_set_cb(req, cb, NULL);
    evhttp_send(req, http);

    event_base_dispatch(base);

    evhttp_free(http);
    evhttp_free(req);
    event_base_free(base);

    return 0;
}
  1. 编译示例代码:
gcc server.c -o server -levent -levent_http
gcc client.c -o client -levent -levent_http
  1. 运行服务器:
./server
  1. 运行客户端:
./client

现在你已经成功创建了一个简单的Socket.5服务器和客户端。请注意,这个示例使用了libevent库,而不是原生的Socket.5库,因为Socket.5并不是一个标准的协议。
