问题描述
我遇到了一个名为mongoose的嵌入式网络服务器,并 http://code.google.com/p/mongoose/和我读的wiki它是伟大的,我搜索一些样本hello世界程序,但我找不到它...我发现了一些例子,但是用c ++编写的windows和任何一个提供一个示例c程序
I came across an embedded web server named mongoose and http://code.google.com/p/mongoose/ and I read the wiki it was great and i searched for some sample hello world program but i couldn't find it... i found some example but that was written in c++ for windows and can any one provide an example c program to run this webserver..
推荐答案
很简单,首先你需要实现回调函数:
It is quite simple, first you need to implement the call back function:
void *event_handler(enum mg_event event,
struct mg_connection *conn) {
const struct mg_request_info *request_info = mg_get_request_info(conn);
static void* done = "done";
if (event == MG_NEW_REQUEST) {
if (strcmp(request_info->uri, "/hello") == 0) {
// handle c[renderer] request
if(strcmp(request_info->request_method, "GET") != 0) {
// send error (we only care about HTTP GET)
mg_printf(conn, "HTTP/1.1 %d Error (%s)\r\n\r\n%s",
500,
"we only care about HTTP GET",
"we only care about HTTP GET");
// return not null means we handled the request
return done;
}
// handle your GET request to /hello
char* content = "Hello World!";
char* mimeType = "text/plain";
int contentLength = strlen(content);
mg_printf(conn,
"HTTP/1.1 200 OK\r\n"
"Cache: no-cache\r\n"
"Content-Type: %s\r\n"
"Content-Length: %d\r\n"
"\r\n",
mimeType,
contentLength);
mg_write(conn, content, contentLength);
return done;
}
}
// in this example i only handle /hello
mg_printf(conn, "HTTP/1.1 %d Error (%s)\r\n\r\n%s",
500, /* This the error code you want to send back*/
"Invalid Request.",
"Invalid Request.");
return done;
}
// No suitable handler found, mark as not processed. Mongoose will
// try to serve the request.
return NULL;
}
然后您需要启动服务器:
Then you need to start the server:
int main(int argc, char **argv) {
/* Default options for the HTTP server */
const char *options[] = {
"listening_ports", "8081",
"num_threads", "10",
NULL
};
/* Initialize HTTP layer */
static struct mg_context *ctx;
ctx = mg_start(&event_handler, options);
if(ctx == NULL) {
exit(EXIT_FAILURE);
}
puts("Server running, press enter to exit\n");
getchar();
mg_stop(ctx);
return EXIT_SUCCESS;
}
