Arduino_W5100连接yeelink网络控制LED

以下是代码：

#include

#include //QQ群：51798659  XiaoHe此代码是用以太网连接yeelink平台实现点亮一个led，访问http://api.yeelink.net/v1.1/device/357400/sensor/405555/datapoints/后面提交的是key来获取一个网页信息，然后再加以提出需要的判断
byte buff[2];
int led=5;//led脚
// for yeelink api
#define APIKEY         "c2a4877a26b7bd000872227c60b67406" // 此处替换为你自己的API KEY
#define DEVICEID       357400 // 此处替换为你的设备编号
#define SENSORID       405555 // 此处替换为你的传感器编号
char pd='v'; //写的一个字符判断byte mac[] = { 0x00, 0x1D, 0x72, 0x82, 0x35, 0x9D};
EthernetClient client ;
char server[] = "api.yeelink.net";   // 连接 的服务器地址
unsigned long lastConnectionTime = 0;          // last time you connected to the server, in milliseconds
boolean lastConnected = false;                 // state of the connection last time through the main loop
const unsigned long postingInterval = 1*1000; // delay between 2 datapoints,  延时多少秒访问一次
String returnValue = ""; 
boolean ResponseBegin = false;void setup() {pinMode(5, OUTPUT);Wire.begin();Serial.begin(115200);if (Ethernet.begin(mac) == 0) {Serial.println("Failed to configure Ethernet using DHCP");for(;;);}else {Serial.println("Ethernet configuration OK");}
}void loop() {if (client.available()) {char c = client.read();// Serial.print(c);if (c == '{')ResponseBegin = true;else if (c == '}')ResponseBegin = false;if (ResponseBegin)returnValue += c;   }if (returnValue.length() !=0 && (ResponseBegin == false)){Serial.println(returnValue);//打印出接收的数据pd=returnValue.charAt(9);//取第几位字符Serial.print("Jie Shou de zifu:");//串口方便好看Serial.println(pd);if (pd == '1') {Serial.println("turn ON ON ON ON the LED"); digitalWrite(led, HIGH);} else if(pd== '0') {Serial.println("turn off off off the LED_____________");     digitalWrite(led, LOW);}returnValue = "";}if (!client.connected() && lastConnected) {Serial.println();Serial.println("disconnecting.");client.stop();}if(!client.connected() && (millis() - lastConnectionTime > postingInterval)) {Serial.print("yeelink:");getData();}lastConnected = client.connected();
}
void getData(void) {if (client.connect(server, 80)) {Serial.println("connecting...");// send the HTTP GET request:client.print("GET /v1.1/device/");client.print(DEVICEID);client.print("/sensor/");client.print(SENSORID);client.print("/datapoints");client.println(" HTTP/1.1");client.println("Host: api.yeelink.net");client.print("Accept: *");client.print("/");client.println("*");client.print("U-ApiKey: ");client.println(APIKEY);client.println("Content-Length: 0");client.println("Connection: close");client.println();Serial.println("print get done.");} else {// if you couldn't make a connection:Serial.println("connection failed");Serial.println();Serial.println("disconnecting.");client.stop();}lastConnectionTime = millis();
}
