它不断地失败,失败,失败。
我有这个密码。如果值“reboot”找到它执行操作,则它必须转到站点并获取值“reboot”;如果“reboot”没有执行其他操作,则它必须执行其他操作。
有时reboot命令是有效的,但它并不总是有效,这让我很难过。
有人知道为什么我的代码不能工作吗?
#include <Bridge.h>
#include <HttpClient.h>
String result = String("");
void setup() {
delay(5000);
pinMode(2, OUTPUT);
Bridge.begin();
digitalWrite(2, HIGH);
}
void loop() {
HttpClient client;
// PIN 2
client.get("http://www.example.com/output.php?value=reboot");// output.php outputs the value reboot and the reset the value to empty string. after 10 second php puts the value to reboot and then put the value to empty.
result = "";
while (client.available()) {
char c = client.read();
result = result + c;
}
if(result.indexOf("reboot") >= 0) {// this keeps failing, sometime working and sometime not working
digitalWrite(2, LOW);
delay(3000);
digitalWrite(2, HIGH);
}
delay(7000);
}
最佳答案
它起作用了。
#include <Bridge.h>
#include <HttpClient.h>
String result = String("");
void setup() {
delay(5000);
pinMode(2, OUTPUT);
Bridge.begin();
digitalWrite(2, HIGH);
}
boolean was_on = false;
void loop() {
HttpClient client;
// PIN 2
client.get("http://ok.example.com/ajax/light");
delay(500);
result = "";
while (client.available()) {
char c = client.read();
result = result + c;
}
if(result.indexOf("reboot") >= 0) {
digitalWrite(2, LOW);
delay(2000);
was_on = true;
} else {
if(was_on) {
digitalWrite(2, HIGH);
delay(1000);
was_on = false;
}
}
delay(3000);
}
