Question

当if条件符合要求时，我只是想让自己“http://192.168.1.103:30000/?k=23&v=capture”。

#include <ESP8266WiFi.h>
// I purposely don't include the ssid and ssid1 here
WiFiServer server(80);

void setup() {
  pinMode(1, INPUT);
  Serial.begin(115200);
  delay(10);
  Serial.println();
  WiFi.softAP(ssid1, password1);
  Serial.println(WiFi.localIP());
  Serial.println();
  Serial.print("Connecting to ");
  Serial.println(ssid);
  WiFi.mode(WIFI_AP_STA);
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }
  Serial.println("");
  Serial.println("WiFi connected");
  Serial.println("IP address: ");
  Serial.println(WiFi.localIP());
  // Start the server
  server.begin();
  Serial.println("Server started");
}

void loop() {
  String link = "http://192.168.1.103:30000/?k=23&v=capture";
  WiFiClient client = server.available();
  if (!client) {
    return;
  }
  int var = digitalRead(1);
  if (var == HIGH) {
    client.print(link);
  }

让我们说：

我已经投放了Chrome。
如果不在Chrome上输入上述链接，如何调用上述链接？我想自动连接它。

你能教的任何方法？我觉得这段代码本身就错了。感谢。

UNO的新代码

//language c++

#include <Servo.h>
#include <Wire.h>
#include <LiquidCrystal_I2C.h>

#define I2C_ADDR 0x3F // Scanning address
LiquidCrystal_I2C lcd(I2C_ADDR, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE); // Set the LCD I2C address
Servo Servo1;
int servopin = 9;

void setup() {
  Serial.begin(9600);
  lcd.begin(16, 2);
  // initialize the lcd for 16 chars 2 lines, turn on backlight
  lcd.backlight(); // finish with backlight on
  lcd.setCursor(3, 0); //Start at character 4 on line 0
  lcd.print("WAITING...");
  pinMode(12, OUTPUT); // pin LaserLight
  pinMode(11, INPUT); // pin LaserDetector
  pinMode(10, INPUT); // pin PIR

  Servo1.attach(servopin);
}

void loop() {
  digitalWrite(12, HIGH);

  boolean inputpir = digitalRead(10);
  Serial.println(inputlaser);
  Serial.println(inputpir);
  if (inputlaser < 1) {
    digitalWrite(8, HIGH);
    lcd.setCursor(0, 0);
    lcd.print("camera on");
    lcd.setCursor(0, 1);
    lcd.print("robber!");
    delay(5000);
    Servo1.write(180);
  } else if (inputpir > 0) {
    Servo1.write(180);
    lcd.setCursor(0, 0);
    lcd.print("robber inside!");
    lcd.setCursor(0, 1);
    lcd.print("HELP ROBBER!");
    delay(500);
  } else {
    lcd.clear();
    lcd.setCursor(3, 0);
    lcd.print("standby...");
    delay(500);

MCU的新代码

#include <ESP8266WiFi.h>

char server[] = "192.168.1.103";
WiFiClient client;

void setup() {
  pinMode(4, INPUT);
  digitalWrite(4, LOW);
  Serial.begin(115200);
  delay(10);
  Serial.println();
  WiFi.softAP(ssid1, password1);
  Serial.println(WiFi.localIP());
  Serial.println();

  WiFi.mode(WIFI_AP_STA);
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }
  Serial.println("");
  Serial.println("WiFi connected");
  Serial.println("IP address: ");
  Serial.println(WiFi.localIP());
}

void loop() {
  boolean var = digitalRead(4);
  if (var == HIGH) {
    client.connect(server, 30000);
    Serial.println("connected");
    // Make your API request:
    client.println("GET /?k=23&v=capture");
    client.println("Host: 192.168.1.103");
    client.println("Connection: close");
    client.println();
  } else {
    // if you didn't get a connection to the server:
    Serial.println("connection failed");
  }
  Serial.println(digitalRead(4));
}

Answer 1

首先要了解一个事实，即您不需要Google Chrome来请求网站。

 client.println("GET /?k=23&v=capture");
 client.println("Host: 192.168.1.103");

您在上述行中执行的操作是您在IP地址/?k=23&v=capture中请求192.168.1.103已解决的内容，这实际上就是您使用Google Chrome时所执行的操作。在PC上，你需要谷歌浏览器（或任何其他浏览器）来获取网站请求，因为每次都难以使用命令请求（想想使用一些http命令而不是使用chrome来请求单个页面，哦，那就是＆＃39;混乱）。因此，了解访问网站并不需要Chrome。

使用Arduino IDE转到使用if条件的链接
