Question

我正在尝试实现一个非常简单的HTTP服务器C代码，同时我在网上进行了搜索： https://medium.com/from-the-scratch/http-server-what-do-you-need-to-know-to-build-a-simple-http-server-from-scratch-d1ef8945e4fa

然后我复制并粘贴下面显示的代码。（还有链接中的代码）

然后构建它并在MacBook上运行它，并且它可以在我的计算机上运行，因此我在Safari上输入了“ localhost：8080”。

我只有这个结果。

Safari无法连接到服务器 Safari无法打开页面“ localhost：8080”，因为Safari无法连接到服务器“ localhost”。

我不知道为什么这不起作用。根据那个站点的说法，它应该工作，所以我现在很沮丧。

有人请帮助我吗？

// Server side C program to demonstrate HTTP Server programming
#include <stdio.h>
#include <sys/socket.h>
#include <unistd.h>
#include <stdlib.h>
#include <netinet/in.h>
#include <string.h>

#define PORT 8080
int main(int argc, char const *argv[])
{
    int server_fd, new_socket; long valread;
    struct sockaddr_in address;
    int addrlen = sizeof(address);

    // Only this line has been changed. Everything is same.
    char *hello = "HTTP/1.1 200 OK\nContent-Type: text/plain\nContent-Length: 12\n\nHello world!";

    // Creating socket file descriptor
    if ((server_fd = socket(AF_INET, SOCK_STREAM, 0)) == 0)
    {
        perror("In socket");
        exit(EXIT_FAILURE);
    }


    address.sin_family = AF_INET;
    address.sin_addr.s_addr = INADDR_ANY;
    address.sin_port = htons( PORT );

    memset(address.sin_zero, '\0', sizeof address.sin_zero);


    if (bind(server_fd, (struct sockaddr *)&address, sizeof(address))<0)
    {
        perror("In bind");
        exit(EXIT_FAILURE);
    }
    if (listen(server_fd, 10) < 0)
    {
        perror("In listen");
        exit(EXIT_FAILURE);
    }
    while(1)
    {
        printf("\n+++++++ Waiting for new connection ++++++++\n\n");
        if ((new_socket = accept(server_fd, (struct sockaddr *)&address, (socklen_t*)&addrlen))<0)
        {
            perror("In accept");
            exit(EXIT_FAILURE);
        }

        char buffer[30000] = {0};
        valread = read( new_socket , buffer, 30000);
        printf("%s\n",buffer );
        write(new_socket , hello , strlen(hello));
        printf("------------------Hello message sent-------------------");
        close(new_socket);
    }
    return 0;
}

简单的HTTP Server C代码在我的Mac OS X上不起作用
