关于mongoose由http转换成https在Linux下笔记（2）

重新梳理一下mongoose的源码程序，mongoose的源码只有mongoose.c和mongoose.h两个文件。

但是在mongoose6.4的版本上mongoose.h里已经定义了使用ssl的宏定义，用户只需要在 #define MG_ENABLE_SSL //使能https

mongoose的提交发布的网址：https://github.com/cesanta/mongoose/releases   这个网址可以查看发布的历史，

点击箭头进入找到源码，

然后按照github的例子进行配置始终编译不过，github的源码如下

文件名称叫 simplest_web_server_ssl.c

#if MG_ENABLE_SSL
/*
 * This example starts an SSL web server on https://localhost:8443/
 *
 * Please note that the certificate used is a self-signed one and will not be
 * recognised as valid. You should expect an SSL error and will need to
 * explicitly allow the browser to proceed.
 */

#include "mongoose.h"

static const char *s_http_port = "8443";
static const char *s_ssl_cert = "server.pem";
static const char *s_ssl_key = "server.key";
static struct mg_serve_http_opts s_http_server_opts;

static void ev_handler(struct mg_connection *nc, int ev, void *p) {
  if (ev == MG_EV_HTTP_REQUEST) {
    mg_serve_http(nc, (struct http_message *) p, s_http_server_opts);
  }
}

int main(void) {
  struct mg_mgr mgr;
  struct mg_connection *nc;
  struct mg_bind_opts bind_opts;
  const char *err;

  mg_mgr_init(&mgr, NULL);
  memset(&bind_opts, 0, sizeof(bind_opts));
  bind_opts.ssl_cert = s_ssl_cert;
  bind_opts.ssl_key = s_ssl_key;
  bind_opts.error_string = &err;

  printf("Starting SSL server on port %s, cert from %s, key from %s\n",
         s_http_port, bind_opts.ssl_cert, bind_opts.ssl_key);
  nc = mg_bind_opt(&mgr, s_http_port, ev_handler, bind_opts);
  if (nc == NULL) {
    printf("Failed to create listener: %s\n", err);
    return 1;
  }

  // Set up HTTP server parameters
  mg_set_protocol_http_websocket(nc);
  s_http_server_opts.document_root = ".";  // Serve current directory
  s_http_server_opts.enable_directory_listing = "yes";

  for (;;) {
    mg_mgr_poll(&mgr, 1000);
  }
  mg_mgr_free(&mgr);

  return 0;
}
#else
int main(void) {
  return 0;
}
#endif /* MG_ENABLE_SSL */
但是，以上代码是6.6的版本下的https，我使用的是mongoose6.4  有些地方是不兼容的，

所以下载6.4的版本时，也是宏定义一个#define MG_ENABLE_SSL //使能https

但是在main里边要这么写

int main（）

{
struct mg_mgr mgr;
struct mg_connection *nc;
//https by lide
struct mg_mgr mgrs;
struct mg_connection *c;
struct mg_bind_opts bind_opts;

(void) signal(SIGCHLD, signal_handler);
(void) signal(SIGTERM, signal_handler);
(void) signal(SIGINT,  signal_handler);
(void) signal(SIGTSTP, signal_handler);
if (signal(SIGSEGV, dump_backtrace) == SIG_ERR)
printf("can't catch SIGSEGV");


memset(&bind_opts, 0, sizeof(bind_opts));
    bind_opts.ssl_cert = "/home/linux/http/server.pem";
//bind_opts.ssl_key = "/home/linux/http/key.pem";

// Use bind_opts to specify SSL certificate & key file
mg_mgr_init(&mgr, NULL);
nc = mg_bind_opt(&mgr, "443", ev_handler, bind_opts);



/* Set up HTTP server parameters */
mg_set_protocol_http_websocket(nc);
  // Set up HTTP server parameters
  mg_set_protocol_http_websocket(nc);
  s_http_server_opts.document_root = ".";  // Serve current directory
  s_http_server_opts.enable_directory_listing = "yes";



while (1) {
mg_mgr_poll(&mgr, 1000);
}
mg_mgr_free(&mgr);
return 0;
}
