要确保你使用的IP地址是空闲的,就是说在局域网内,没有其他设备正在使用这个地址。 定义连接要用到的EthernetClient变量。 程序2-3给出了建立以太网连接所用的代码。connectToInternet()函数首先试图通过DHCP来连接到以太网。如果DHCP无法给Arduino分配一个动态IP地址,就会用之前定义的静态IP地址来连接以太网。 一旦Ard...
本节,我们开始学习wemos D1的HTTP Client编程,并实现通过HTTP GET方式获取天气信息的功能。 一、基础知识 1.HTTP简介 1.1 HTTP概要 HTTP是Hypertext Transfer Protocol的缩写,Hypertext(超文本)是可以根据客户端请求而跳转的结构化信息。HTTP协议的请求及相应方式设计如下图所示: 从图中可以看出,服务器端响应客户端请...
通过将ESPDuino开发板设置成TCP Client模式,从而达到联网通信 具体方法 登录http://tcp.doit.am获取要使用的IP和端口: 程序流程 设置热点账号和密码 const char* ssid="" const char* password="" 设置服务器IP const char* serverIP=“115.29.109.104” ...
client.println("GET /search?q=arduino HTTP/1.1"); client.println("Host: www.google.com"); client.println("Connection: close"); client.println(); } else { // if you didn't get a connection to the server: Serial.println("connection failed"); ...
if (client.available()) { String response = client.readStringUntil('\r'); Serial.println(response); } } // 关闭连接 client.stop(); } // 延时一段时间 delay(5000); // 自定义发送数据的间隔 } 在以上代码中,首先连接到WIFI网络,然后在主循环中获取传感器数据,并构建HTTP请求,最后通过TCP连接将...
