Question

我第一次发帖，但我真的被困了，需要帮助。

我目前正在开发一个家庭自动化系统，我想用路由器控制远程Arduino设备。

这一部分全部完成，我可以使用可以打开或关闭的浏览器连接到链接。我甚至用它做了一个应用程序。

目前我正在处理语音识别代码，它接受代码然后转换为语音，语音识别部分与SpeechRecognition库一起工作，一旦python理解代码，它必须给出命令和使用网址。

如果我尝试访问http://www.google.com这样的网址，我认为它有效，但我的网址是“http://192.168.0.227/LED=ON14”，当使用它时，程序挂起然后超时，我已经尝试了几种方法控制它，但它们似乎都不起作用。

import urllib2

sock = urllib2.urlopen("http://192.168.0.227/LED=ON14") 
htmlSource = sock.read()                            
sock.close()                                        
print htmlSource

这是我最近的试用

以该回复结束。

我的Arduino代码适用于ESP8266：

#include <ESP8266WiFi.h>

const char* ssid = "--";
const char* password = "--";

WiFiServer server(80);

void setup() {
  Serial.begin(115200);
  delay(10);
  pinMode(14, OUTPUT);  pinMode(12, OUTPUT);  pinMode(13, OUTPUT);  pinMode(15, OUTPUT);
  digitalWrite(14, LOW);digitalWrite(12, LOW);digitalWrite(13, LOW);digitalWrite(15, LOW);  digitalWrite(2,LOW);

  // Connect to WiFi network
  Serial.println();
  Serial.println();
  Serial.print("Connecting to ");
  Serial.println(ssid);

IPAddress ip(192, 168, 0, 106);
IPAddress gateway(192, 168, 0, 1);
IPAddress subnet(255, 255, 255, 0);
IPAddress dns(192, 168, 0, 1);

// Static IP Setup Info Here...
WiFi.config(ip,dns, gateway, subnet); //If you need Internet Access You should Add DNS also... 
WiFi.begin(ssid, password);

  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }
  Serial.println("");
  Serial.println("WiFi connected");

  // Start the server
  server.begin();
  Serial.println("Server started");

  // Print the IP address
  Serial.print("Use this URL to connect: ");
  Serial.print("http://");
  Serial.print(WiFi.localIP());
  Serial.println("/");

}

void loop() {
  // Check if a client has connected
  WiFiClient client = server.available();
  if (!client) {
    return;
  }

  // Wait until the client sends some data
  Serial.println("new client");
  while(!client.available()){
    delay(1);
  }

  // Read the first line of the request
  String request = client.readStringUntil('\r');
  Serial.println(request);
  client.flush();
    int value = LOW;
// Return the response
 /*client.println("HTTP/1.1 200 OK");
  client.println("Content-Type: text/html");
  client.println(""); //  do not forget this one

    client.println("<a href=\"/LED=ON15\"\"><button>Turn On 1 </button></a>");
  client.println("<a href=\"/LED=OFF15\"\"><button>Turn Off 1</button></a><br />");  
  client.println("</html>"); */

  client.println("HTTP/1.1 200 OK");
  client.println("Content-Type: text/html");
  client.println(""); //  do not forget this one
  client.println("<!DOCTYPE HTML>");
  client.println("<html>");

  client.print("Led pin is now: ");

  delay(1);
  Serial.println("Client disonnected");
  Serial.println("");

  // Match the request


  if (request.indexOf("/ON4") != -1)  {
    digitalWrite(14, LOW);
    value = HIGH;
  }
  if (request.indexOf("/OFF4") != -1)  {
    digitalWrite(14, HIGH);
    value = LOW;
  }
    if (request.indexOf("/ON3") != -1)  {
    digitalWrite(13, LOW);
    value = HIGH;
  }
  if (request.indexOf("/OFF3") != -1)  {
    digitalWrite(13, HIGH);
    value = LOW;
  }
    if (request.indexOf("/ON2") != -1)  {
    digitalWrite(12, LOW);
    value = HIGH;
  }
  if (request.indexOf("OFF2") != -1)  {
    digitalWrite(12, HIGH);
    value = LOW;
  }
    if (request.indexOf("/ON1") != -1)  {
    digitalWrite(15, LOW);
    value = HIGH;
  }
  if (request.indexOf("/OFF1") != -1)  {
    digitalWrite(15, HIGH);
    value = LOW;
  }



}

Answer 1

我认为'urllib2'可能正在寻找结束html括号</html> 尝试在client.println("</html>");和client.print("Led pin is now: ");之间加delay(1); 此外，如果您希望将LED状态打印到客户端，则应将LED控制语句移到您发送给客户端的代码上方并传入value。

所以你的代码看起来像这样。

#include <ESP8266WiFi.h>

const char* ssid = "--";
const char* password = "--";

WiFiServer server(80);

void setup() {
  Serial.begin(115200);
  delay(10);
  pinMode(14, OUTPUT);  pinMode(12, OUTPUT);  pinMode(13, OUTPUT);  pinMode(15, OUTPUT);
  digitalWrite(14, LOW);digitalWrite(12, LOW);digitalWrite(13, LOW);digitalWrite(15, LOW);  digitalWrite(2,LOW);

  // Connect to WiFi network
  Serial.println();
  Serial.println();
  Serial.print("Connecting to ");
  Serial.println(ssid);

  IPAddress ip(192, 168, 0, 106);
  IPAddress gateway(192, 168, 0, 1);
  IPAddress subnet(255, 255, 255, 0);
  IPAddress dns(192, 168, 0, 1);

  // Static IP Setup Info Here...
  WiFi.config(ip,dns, gateway, subnet); //If you need Internet Access You should Add DNS also... 
  WiFi.begin(ssid, password);

  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }
  Serial.println("");
  Serial.println("WiFi connected");

  // Start the server
  server.begin();
  Serial.println("Server started");

  // Print the IP address
  Serial.print("Use this URL to connect: ");
  Serial.print("http://");
  Serial.print(WiFi.localIP());
  Serial.println("/");

}

void loop() {
  // Check if a client has connected
  WiFiClient client = server.available();
  if (!client) {
    return;
  }

  // Wait until the client sends some data
  Serial.println("new client");
  while(!client.available()){
    delay(1);
  }

  // Read the first line of the request
  String request = client.readStringUntil('\r');
  Serial.println(request);
  client.flush();

  // Match the request
  int value = LOW;    

  if (request.indexOf("/ON4") != -1)  {
    digitalWrite(14, LOW);
    value = HIGH;
  }
  if (request.indexOf("/OFF4") != -1)  {
    digitalWrite(14, HIGH);
    value = LOW;
  }
    if (request.indexOf("/ON3") != -1)  {
    digitalWrite(13, LOW);
    value = HIGH;
  }
  if (request.indexOf("/OFF3") != -1)  {
    digitalWrite(13, HIGH);
    value = LOW;
  }
    if (request.indexOf("/ON2") != -1)  {
    digitalWrite(12, LOW);
    value = HIGH;
  }
  if (request.indexOf("/OFF2") != -1)  {
    digitalWrite(12, HIGH);
    value = LOW;
  }
    if (request.indexOf("/ON1") != -1)  {
    digitalWrite(15, LOW);
    value = HIGH;
  }
  if (request.indexOf("/OFF1") != -1)  {
    digitalWrite(15, HIGH);
    value = LOW;
  }


  // Return the response
  /*client.println("HTTP/1.1 200 OK");
  client.println("Content-Type: text/html");
  client.println(""); //  do not forget this one
  client.println("<!DOCTYPE HTML>");
  client.println("<html>");
  client.println("<br><br>");
  client.println("<a href=\"/LED=ON14\"\"><button>Turn On 4 </button></a>");
  client.println("<a href=\"/LED=OFF14\"\"><button>Turn Off 4</button></a><br />");  
    client.println("<a href=\"/LED=ON12\"\"><button>Turn On 2 </button></a>");
  client.println("<a href=\"/LED=OFF12\"\"><button>Turn Off 2</button></a><br />");  
    client.println("<a href=\"/LED=ON13\"\"><button>Turn On 3 </button></a>");
  client.println("<a href=\"/LED=OFF13\"\"><button>Turn Off 3</button></a><br />");  
    client.println("<a href=\"/LED=ON15\"\"><button>Turn On 1 </button></a>");
  client.println("<a href=\"/LED=OFF15\"\"><button>Turn Off 1</button></a><br />");  
  client.println("</html>"); */

  client.println("HTTP/1.1 200 OK");
  client.println("Content-Type: text/html");
  client.println(""); //  do not forget this one
  client.println("<!DOCTYPE HTML>");
  client.println("<html>");

  client.print("Led pin is now: ");
  client.println(value);                  // Parse in the value
  client.println("</html>");              // Add this

  delay(1);
  Serial.println("Client disonnected");
  Serial.println("");

}

不幸的是，我现在没有能力测试这个，所以我跳了它的工作原理。其他人发表评论。
