Mongoose 多线程服务端

mongoose 的 release 版本下载：https://github.com/cesanta/mongoose/releases

下面代码，只适用于mongoose 6.7及其以下版本，从6.8版本开始，不适用该方式创建多线程（使用的是 mg_socketpair 创建全双工的方式实现数据转发）。

#include "stdafx.h"
#include "mongoose-6.7/mongoose.h"

static const char *s_http_port = "7879";

static void ev_handler(struct mg_connection *c, int ev, void *p) {
	if (ev == MG_EV_HTTP_REQUEST) {
		struct http_message *hm = (struct http_message *) p;
		char reply[100];

		/* Simulate long calculation */
		//sleep(3);

		/* Send the reply */
		snprintf(reply, sizeof(reply), "{ \"uri\": \"%.*s\" }\n", (int) hm->uri.len, hm->uri.p);
		mg_printf(c, "HTTP/1.1 200 OK\r\n"
			"Content-Type: application/json\r\n"
			"Content-Length: %d\r\n"
			"\r\n"
			"%s",
			(int) strlen(reply), reply);
	}
}


int main(void) {
	struct mg_mgr mgr;

	mg_mgr_init(&mgr, NULL);
	struct mg_connection *nc = mg_bind(&mgr, s_http_port, ev_handler);

	mg_set_protocol_http_websocket(nc);

	/* For each new connection, execute ev_handler in a separate thread */
	mg_enable_multithreading(nc);//from v6.8, removed mg_enable_multithreading. 

	printf("starting multi-threaded server on port %s\n", s_http_port);
	for (;;) {
		mg_mgr_poll(&mgr, 500);
	}
	mg_mgr_free(&mgr);

	return 0;
}
