ESP8266校园网登录

校园网登录通常需要进行身份验证，这里是一个使用ESP8266模块登录校园网的基本示例代码：

#include <ESP8266WiFi.h>

const char* ssid = "YOUR_SSID";
const char* password = "YOUR_PASSWORD";
const char* loginUrl = "LOGIN_URL";

void setup() {
  Serial.begin(115200);
  delay(10);
  
  WiFi.begin(ssid, password);
  
  while (WiFi.status() != WL_CONNECTED) {
    delay(1000);
    Serial.println("Connecting to WiFi...");
  }
  
  Serial.println("Connected to WiFi");
  
  loginToCampusNetwork();
}

void loop() {
  // Your main code here
}

void loginToCampusNetwork() {
  WiFiClient client;
  
  // Connect to the login page
  if (client.connect("login.campuswifi.com", 80)) {
    Serial.println("Connected to login page");
    
    // Send the login request
    String postData = "username=YOUR_USERNAME&password=YOUR_PASSWORD";
    client.println("POST /login HTTP/1.1");
    client.println("Host: login.campuswifi.com");
    client.println("Content-Type: application/x-www-form-urlencoded");
    client.print("Content-Length: ");
    client.println(postData.length());
    client.println();
    client.print(postData);
    
    delay(500); // Wait for the server to respond
    
    // Read the response from the server
    while (client.available()) {
      String line = client.readStringUntil('\r');
      Serial.print(line);
    }
    
    Serial.println("Login complete");
    
    // Close the connection
    client.stop();
  }
  else {
    Serial.println("Failed to connect to login page");
  }
}

请将 `YOUR_SSID`、`YOUR_PASSWORD`、`YOUR_USERNAME` 和 `YOUR_PASSWORD` 替换为你的校园网信息。`LOGIN_URL` 是用于登录的网址，根据你所在学校的不同可能有所不同。

注意：这是一个基本示例，具体的校园网登录逻辑可能因学校而异。你可能需要根据你的校园网要求进行适当的修改。
