Details:
http_find_error_file()
call
http_init_file(uri)
call
get_http_headers(uri)
when LWIP_HTTPD_DYNAMIC_HEADERS is enable,
if uri is null, get_http_headers() always set http response 404.
so if error_nr is not 404, http_find_error_file(error_nr) take
the bad response header!
static err_t
http_find_error_file(struct http_state *hs, u16_t error_nr)
{
const char *uri1, *uri2, *uri3;
const char *uri;
err_t err;
if (error_nr == 501) {
uri1 = "/501.html";
uri2 = "/501.htm";
uri3 = "/501.shtml";
} else {
/* 400 (bad request is the default) */
uri1 = "/400.html";
uri2 = "/400.htm";
uri3 = "/400.shtml";
}
err = fs_open(&hs->file_handle, uri = uri1);
if (err != ERR_OK) {
err = fs_open(&hs->file_handle, uri = uri2);
if (err != ERR_OK) {
err = fs_open(&hs->file_handle, uri = uri3);
if (err != ERR_OK) {
LWIP_DEBUGF(HTTPD_DEBUG, ("Error page for error %"U16_F" not
found\n",
error_nr));
return ERR_ARG;
}
}
}
return http_init_file(hs, &hs->file_handle, 0, uri, 0, NULL);
}
