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);
}
