如何通过我们的浏览器访问Spark核心？

我想让内核像一个Web服务器一样，在使用此命令>>>（client.println（“ Sorry”）;）通过webrowser访问时显示文本，它应该在浏览器中显示“ sorry”吗？但是当我在浏览器中键入核心的IP时。它说“此网页不可用”

感谢您的阅读。

TCPServer server = TCPServer(80);
    TCPClient client;

    void setup()
    {
      // start listening for clients
      server.begin();

      // Make sure your Serial Terminal app is closed before powering your Core
      Serial.begin(9600);
      // Now open your Serial Terminal, and hit any key to continue!
      while(!Serial.available()) SPARK_WLAN_Loop();

      Serial.println(WiFi.localIP());
      Serial.println(WiFi.subnetMask());
      Serial.println(WiFi.gatewayIP());
      Serial.println(WiFi.SSID());
    }

    void loop()
    {
      if (client.connected()) {
        // echo all available bytes back to the client
        while (client.available()) {
          server.write(client.read());
          server.write("Hello world!");
          client.println("Sorry"); //<<<<<<<<<<<<<<should show this
        }
      } else {
        // if no client is yet connected, check for a new connection
        client = server.available();
      }
    }

这是我在arduino和ethernet sheild中使用的代码，可以正常工作

#include <SPI.h>
#include <Ethernet.h>

//Enter a new MAC address from your computer MAC plus one.
byte mac[] = { 0x00, 0xAA, 0xBB, 0xCC, 0xDE, 0x02 };
EthernetServer server(80); // Create new server object at selected port

void setup() {

  Serial.begin(9600);
  Serial.println("Requesting ip address ...");
  Ethernet.begin(mac,ip,gateway,subnet);
  Serial.print("My IP address: ");
  Serial.print(Ethernet.localIP());
  server.begin(); // begin listening
}

void loop() {
  EthernetClient client = server.available(); // Get connection
  if(server.available()){ // check if there are connection
    Serial.println("new client connection");
    while (client.connected()) { // check if the client still alive
      if (client.available()) { // check if the connection are still alive
        char c = client.read(); // read data from Ethernet buffer
        if(c=='='){ p = client.read(); }
        Serial.write(c);
        if(c == '\n'){ // check if there are terminate character
          client.println("sorry");
          break;
        }
      }
    }
    client.stop(); // disconnect from client
    Serial.println("client disconnected");
  }
  delay(1000);
