Mongoose basic example

[Gustavo Santana]

Hi everybody!

I compiled the hello.c example but when I acess localhost:8080 I get the message:

"Hello! Requested URI is [/], query string is [(none)]"

I want to load the index.html file that is in the same folder of hello bin

What is the problem?

I'm using ubuntu and here is the source:

#include <stdio.h>

#include <string.h>

#include "mongoose.h"

// This function will be called by mongoose on every new request

static int index_html(struct mg_connection *conn) {

  mg_printf_data(conn, "Hello! Requested URI is [%s], query string is [%s]",

                 conn->uri,

                 conn->query_string == NULL ? "(none)" : conn->query_string);

  return 0;

}

int main(void) {

  struct mg_server *server;

  

  // Create and configure the server

  server = mg_create_server(NULL);

  mg_set_option(server, "listening_port", "8080");

  mg_add_uri_handler(server, "/", index_html);

  // Serve request. Hit Ctrl-C to terminate the program

  printf("Starting on port %s\n", mg_get_option(server, "listening_port"));

  for (;;) {

    mg_poll_server(server, 1000);

  }

  // Cleanup, and free server instance

  mg_destroy_server(&server);

  return 0;

}

Best regards

Gustavo

You need to specify document_root option, and return MG_FALSE for the files inside document_root.

Hi,
I guess you are working on the version 5.1, the latest has a lot of changes of the APIs.
In this version, if you want to load index.html directly, you need remove "mg_add_uri_handler" fuction on the uri "/", and set the "document_root" by
mg_set_option(server, "document_root", "./");

Hello,

I try to compile example hello.c to listening port 80 by modifying this line :

mg_set_option(server, "listening_port", "8080");

to
mg_set_option(server, "listening_port", "80");

When I run, I'm not able to load the page.
Did I missed out anything ?

Thank you.
Regards,
~sam

Port 80 might be busy, or privileged.

You should check the return value of mg_set_option(). If it returns NULL, everything is good. Otherwise it will return a string error that explains what went wrong.
