用arduino库实现8266作为server端实现与pc通信

可以使用WiFiServer库和WiFiClient库,将ESP8266作为server端,与PC进行TCP通信。
以下是一个简单的代码示例:
```
#include <ESP8266WiFi.h>
// Replace with your network credentials
const char* ssid = "your_SSID";
const char* password = "your_PASSWORD";
WiFiServer server(80);
void setup() {
Serial.begin(115200);
delay(10);
// Connect to WiFi
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");
// Start the server
server.begin();
Serial.println("Server started");
}
void loop() {
// Check if a client has connected
WiFiClient client = server.available();
if (!client) {
return;
}
// Wait for the client to send data
Serial.println("New client");
while(!client.available()){
delay(1);
}
// Read the first line of the request
String request = client.readStringUntil('\r');
Serial.println(request);
client.flush();
// Send a response
String response = "Hello World!";
client.print("HTTP/1.1 200 OK\r\n");
client.print("Content-Type: text/html\r\n");
client.print("Connection: close\r\n");
client.print("Content-Length: ");
client.print(response.length());
client.print("\r\n");
client.print("\r\n");
client.print(response);
delay(1);
Serial.println("Client disconnected");
}
```
当ESP8266作为server端时,它会监听80端口,如果有新的客户端连接,它会接受客户端数据,解析请求并发送响应。以上示例代码是一个非常简单的HTTP server,当PC浏览器访问ESP8266的IP地址时,它将打印"Hello World!"。
希望这个示例可以帮助您开始使用ESP8266和arduino库进行server端开发。
