Unable to transfer data between two ESP8266 - sockets

Question

I am trying to connect two esp 8266 (Wi-fi) module with each other one as hotspot (server) using Wifi of ESP12 E module 8266 and other is (client).I am Using Arduino IDE for programming
my server starts properly and client is connected to server but when I send data from client to server I got nothing. I google about data transfer between client and server, but nothing is there for client data transfer using Arduino coding.
Here is My code in Arduino
server side code
#include <ESP8266WiFi.h>
WiFiServer server(80); //Initialize the server on Port 80
void setup()
{
WiFi.mode(WIFI_AP); // ESP8266-12E is an AccessPoint
WiFi.softAP("11111111", "12345678"); // Provide the (SSID, password)
server.begin(); // Start the Server
Serial.begin(115200); //Start communication between the ESP8266-12E and the monitor window
IPAddress HTTPS_ServerIP= WiFi.softAPIP(); // Obtain the IP of the Server
Serial.print("Server IP is: "); // Print the IP to the monitor window
Serial.println(HTTPS_ServerIP);
}
void loop()
{
WiFiClient client = server.available();
if (!client)
{
return;
}
//Looking under the hood
Serial.println("Somebody has connected :)");
}
client side code
#include <ESP8266WiFi.h>
const char *ssid = "11111111";
const char *password = "12345678";
const char *host = "192.168.4.2";
const int httpPort = 80;
void setup()
{
Serial.begin(115200);
delay(10);
Serial.println();
Serial.println();
Serial.print("Connecting to ");
Serial.println(ssid);
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED)
{
delay(500);
Serial.print(".");
}
Serial.println("");
Serial.println("WiFi connected");
Serial.println("IP address: ");
Serial.println(WiFi.localIP());
}
void loop()
{
delay(8000);
Serial.print("connecting to ");
Serial.println(host);
WiFiClient client;
client.connect(host,httpPort);
if (!client.connect(host,httpPort))
{
Serial.println("connection failed");
return;
}
else
client.print("connected");
}
can any one suggest me how to transfer data from client to server

The Arduino ESP8266 class WiFiClient inherits from Stream, so, all stream functions are available to you. You can find documentation for that class here.
You could use readBytes, readString, or just plain read to do what you want.
Additionally, if you do plan to use HTTP, you may be interested in using the libraries ESP8266WebServer and ESP8266HTTPClient which come with your ESP8266 Arduino environment and implement a lot of this low level code you are attempting to write. You can find examples for the server here, and the client here
