how to support the "captive Portal" on ESP8266

[lijay910]

HI
use the code,such as:
LOCAL void ICACHE_FLASH_ATTR
user_udp_recv(void *arg, char *pusrdata, unsigned short length)
{
char DeviceBuffer[40] = {0};
char Device_mac_buffer[60] = {0};
char hwaddr[6];
struct espconn *pesp_conn = arg;
struct ip_info ipconfig;
at_port_print("user_udp_recv\r\n");
//at_port_print(pusrdata);
//m_pespconn =pesp_conn;

remot_info *premot = NULL;
sint8 value = ESPCONN_OK;
char pbuf[100] = {0};
if (espconn_get_connection_info(pesp_conn,&premot,0) == ESPCONN_OK){
pesp_conn->proto.tcp->remote_port = premot->remote_port;
pesp_conn->proto.tcp->remote_ip[0] = premot->remote_ip[0];
pesp_conn->proto.tcp->remote_ip[1] = premot->remote_ip[1];
pesp_conn->proto.tcp->remote_ip[2] = premot->remote_ip[2];
pesp_conn->proto.tcp->remote_ip[3] = premot->remote_ip[3];

os_sprintf(pbuf,"DNS Remote[IP=" IPSTR "][Port=%d]",IP2STR(&pesp_conn->proto.udp->remote_ip), pesp_conn->proto.udp->remote_port);
at_port_print(pbuf);
//espconn_sent(pesp_conn, pusrdata, os_strlen(pusrdata));
espconn_sent(pesp_conn, html, strlen(html));
}
}

but it is never usefull.
after to connet to the EPS82666 AP, but cann't show the portal window on the phone.
how to suport the captive Portal on esp8266??

Interested.

WiFi captive portal for the NodeMCU (ESP8266 Module) with DNS spoofing.

The built-in LED will blink 5 times when a password is posted.

Warning! Your saved passwords will not disappear when you restart/power off the ESP8266.

Note: If you want to see the stored passwords go to "172.0.0.1/pass". For changing the SSID, go to "172.0.0.1/ssid"
