Mongoose 3.0: Receive garbage request data sent in POST call

[Puneet Bakshi]

Hi,

I am using Mongoose 3.0 and ran "test/embed.c" to check for POST request 
data. I was expecting function test_post() would return "aaaaaaaaa" but it 
returns some  funny characters. How can  I get request data sent along with 
POST request? Am I missing something? Does it has do do something with 
"Content-Type" field?

*Compile embed.c*

# cc -g  -o ./embed test/embed.c mongoose.c -I. -pthread -DNO_SSL 
-DLISTENING_PORT=\"23456\"
#./embed

*Run curl to send POST requests*

# cat /root/data
aaaaaaaaa

# curl -X POST  -H "X-Auth-Token:puneet_token"  -d @/root/data  
http://localhost:23456/test_post
$��

# curl -X POST  -H "Content-Type: text/html" -H 
"X-Auth-Token:puneet_token"  -d @/root/data  
http://localhost:23456/test_post
$��

# curl -X POST  -H "Content-Type: text/plain" -H 
"X-Auth-Token:puneet_token"  -d @/root/data  
http://localhost:23456/test_post
$��


*Snippet from embed.c*
:::
static void test_post(struct mg_connection *conn,
                      const struct mg_request_info *ri) {
  const char *cl;
  char *buf;
  int len;

  mg_printf(conn, "%s", standard_reply);
  if (strcmp(ri->request_method, "POST") == 0 &&
      (cl = mg_get_header(conn, "Content-Length")) != NULL) {
    len = atoi(cl);
    if ((buf = malloc(len)) != NULL) {
      mg_write(conn, buf, len);
      printf("buf: %s\n", buf);
      free(buf);
    }
  }
}

static const struct test_config {
  enum mg_event event;
  const char *uri;
  void (*func)(struct mg_connection *, const struct mg_request_info *);
} test_config[] = {
  {MG_NEW_REQUEST, "/test_get_header", &test_get_header},
  {MG_NEW_REQUEST, "/test_get_var", &test_get_var},
  {MG_NEW_REQUEST, "/test_get_request_info", &test_get_request_info},
  {MG_NEW_REQUEST, "/test_post", &test_post},
  {MG_HTTP_ERROR, "", &test_error},
  {0, NULL, NULL}
};

static void *callback(enum mg_event event,
                      struct mg_connection *conn,
                      const struct mg_request_info *request_info) {
  int i;

  for (i = 0; test_config[i].uri != NULL; i++) {
    if (event == test_config[i].event &&
        (event == MG_HTTP_ERROR ||
         !strcmp(request_info->uri, test_config[i].uri))) {
      test_config[i].func(conn, request_info);
      return "processed";
    }
  }

  return NULL;
}

int main(void) {
  struct mg_context *ctx;
  const char *options[] = {"listening_ports", LISTENING_PORT, NULL};

  ctx = mg_start(callback, NULL, options);
  pause();
  return 0;
}
