如何在mongoose Web服务器上保持链接活动

Question

我尝试使用keep-alive连接mongoose,但似乎mongoose首先关闭连接.

我更改了embed.c以发回连接:keep-alive.响应后,连接仍然关闭.

border@ubuntu:~$ nc 127.0.0.1 9999
GET /test_get_request_info HTTP/1.1
Connection: keep-alive

HTTP/1.1 200 OK
Content-Type: text/plain
Connection: keep-alive

Method: [GET]
URI: [/test_get_request_info]
HTTP version: [1/1]
HTTP header [Connection]: [keep-alive]
Query string: []
POST data: []
Remote IP: [2130706433]
Remote port: [56719]
Remote user: []          <-----------------connection closed, nc returns
border@ubuntu:~$

目前,如果不改变Mongoose代码是不可能的.您可以尝试制作技巧,在analyze_request()函数中,设置keep-alive标志:

} else if ((cb = find_callback(conn->ctx, FALSE, uri, -1)) != NULL) {
        if ((strcmp(ri->request_method, "POST") != 0 &&
            strcmp(ri->request_method, "PUT") != 0) ||
            handle_request_body(conn, -1)) {
                cb->func(conn, &conn->request_info, cb->user_data);
                conn->keep_alive = TRUE;  // ADD THIS LINE
            }

但是,必须有更好的机制来从回调中执行此操作.
