Send HTTP response using C socket
提问by spe
I`m trying to send HTTP response to browser
我正在尝试向浏览器发送 HTTP 响应
char *reply =
"HTTP/1.1 200 OK\n"
"Date: Thu, 19 Feb 2009 12:27:04 GMT\n"
"Server: Apache/2.2.3\n"
"Last-Modified: Wed, 18 Jun 2003 16:05:58 GMT\n"
"ETag: \"56d-9989200-1132c580\"\n"
"Content-Type: text/html\n"
"Content-Length: 15\n"
"Accept-Ranges: bytes\n"
"Connection: close\n"
"\n"
"sdfkjsdnbfkjbsf";
int sd = socket(PF_INET, SOCK_STREAM, 0);
struct sockaddr_in addr;
bzero(&addr, sizeof(addr));
addr.sin_family = AF_INET;
addr.sin_port = htons(8081);
addr.sin_addr.s_addr = INADDR_ANY;
if(bind(sd,&addr,sizeof(addr))!=0)
{
printf("bind error\n");
}
if (listen(sd, 16)!=0)
{
printf("listen error\n");
}
for(;;)
{
int size = sizeof(addr);
int client = accept(sd, &addr, &size);
if (client > 0)
{
printf("client connected\n");
send(client, reply, sizeof(reply), 0);
}
}
but my browser cant understand this, waits for a long time and then print smth strange. I guess my response is wrong, but I dont know how to fix. Any ideas?
但是我的浏览器无法理解这一点，等待很长时间然后打印出奇怪的东西。我想我的回答是错误的，但我不知道如何解决。有任何想法吗？

sizeof(reply)evaluates to the size of a char *, aka size of a pointer. Use strlen.
sizeof(reply)计算为 a 的大小char *，也就是指针的大小。使用strlen.
send(client, reply, strlen(reply), 0);
