Question

这可能是一个新手的错误，但我完全不知道该怎么做。

我试图根据我在互联网上找到的代码制作一个代码来阅读推文，但发现Twitter改变了他们的API并且不能再这样做了。

我想要做的就是阅读一条消息并从我的Arduino激活一个引脚来打开模型车库。

到目前为止，我在wix上创建了一个网站，我的arduino能够阅读它。

但是，看它是否适合第一种情况的比较根本不起作用，即使它应该与之前的印刷品相同。

我使用了tweet.length（），它告诉我我的字符串长31个字符，这意味着没有任何隐藏的字符，对吧？

非常感谢任何帮助!!

#include <SPI.h>
#include <Ethernet.h>
boolean requested;                   // whether you've made a request since connecting
long lastAttemptTime = 0;            // last time you connected to the server, in milliseconds
boolean garage_status = false;
String currentLine = "";            // string to hold the text from server
String tweet = "";                  // string to hold the tweet
boolean readingTweet = false; 
// Enter a MAC address for your controller below.
// Newer Ethernet shields have a MAC address printed on a sticker on the shield
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
// if you don't want to use DNS (and reduce your sketch size)
// use the numeric IP instead of the name for the server:
//IPAddress server(74,125,232,128);  // numeric IP for Google (no DNS)
char server[] = "gusat92.wix.com";    // name address for Google (using DNS)

// Set the static IP address to use if the DHCP fails to assign
IPAddress ip(10,32,153,88);

// Initialize the Ethernet client library
// with the IP address and port of the server 
// that you want to connect to (port 80 is default for HTTP):
EthernetClient client;

void setup() {
 // Open serial communications and wait for port to open:
 pinMode(2, OUTPUT);
  Serial.begin(9600);
    currentLine.reserve(256);
  tweet.reserve(150);
   while (!Serial) {
    ; // wait for serial port to connect. Needed for Leonardo only
  }

  // start the Ethernet connection:
  if (Ethernet.begin(mac) == 0) {
    Serial.println("Failed to configure Ethernet using DHCP");
    // no point in carrying on, so do nothing forevermore:
    // try to congifure using IP address instead of DHCP:
    Ethernet.begin(mac, ip);
  }
  // give the Ethernet shield a second to initialize:
  delay(1000);
  Serial.println("connecting...");

  // if you get a connection, report back via serial:
  if (client.connect(server, 80)) {
    Serial.println("connected");
    // Make a HTTP request:
    client.println("GET /garage?_escaped_fragment_ HTTP/1.1");
    client.println("Host: gusat92.wix.com");
    client.println("Connection: close");
    client.println();
  } 
  else {
    // kf you didn't get a connection to the server:
    Serial.println("connection failed");
  }
}

void loop()
{
  if (client.connected()) {
    if (client.available()) {
      // read incoming bytes:
      char inChar = client.read();

      // add incoming byte to end of line:
      currentLine += inChar; 

      // if you get a newline, clear the line:
      if (inChar == '\n') {
        currentLine = "";
      } 
      // if the current line ends with <text>, it will
      // be followed by the tweet:
      if ( currentLine.endsWith("\"Text\">")) {
        // tweet is beginning. Clear the tweet string:
        readingTweet = true; 
        tweet = "";
      }
      // if you're currently reading the bytes of a tweet,
      // add them to the tweet String:
      if (readingTweet) {
        if (inChar != '&') {
          tweet += inChar;
        } 
        else {
          // if you got a "<" character,
          // you've reached the end of the tweet:
          readingTweet = false;
          Serial.println(tweet);
          Serial.println(tweet.length());
          if(tweet == "    <h2 class=\"font_2\">Opener"){//this part is never true
           digitalWrite(2, HIGH);
           delay(5000);
           Serial.println("LED ON!");
           garage_status=true;
           digitalWrite(2, LOW);
          }
          else {Serial.println("no out");}
          if(tweet != "    <h2 class=\"font_2\">Closer" && garage_status==true){
           digitalWrite(3, HIGH);
           delay(5000);
           Serial.println("LED OFF!");
           garage_status=false;
           digitalWrite(3, LOW);
          }

          // close the connection to the server:
          client.stop(); 
        }
      }
    }   
  }
}

这是打印的＆gt;

推文部分与比较完全相同，对吗？：S

比较不工作Arduino
