Question

我正在做一个项目，该项目的一个要素是将数据从esp8266发送到在xampp（也为本地服务器）上创建的数据库。首先，我想检查它的工作原理，因此我将esp连接到计算机，在ArduinoIDE上打开终端并编写了一些AT命令，以将其连接到与笔记本电脑相同的wi-fi，然后通过命令连接到xampp服务器（apache）：

AT+CIPSTART="TCP","192.168.1.15",80

我得到了连接的响应，所以我想通过GET函数发送一些数据

AT+CIPSEND=75
GET /dht.php?temperature=30&humidity=60 HTTP/1.1\r\nHost: 192.168.1.15\r\n

但是我在终端这样的响应：

> GET /dht.php?temperature=30&humidity=60 HTTP/1.1\r\nHost: 192.168.1.15\r\n
SEND OK

您知道我做错了吗？这也是我的dht.php代码，我将其放在xampp文件夹中的“ htdocs”文件夹中

<?php
class dht11{
 public $link='';
 function __construct($temperature, $humidity){
  $this->connect();
  $this->storeInDB($temperature, $humidity);
 }

 function connect(){
  $this->link = mysqli_connect('localhost','root','') or die('Cannot connect to the DB');
  mysqli_select_db($this->link,'projekt_it') or die('Cannot select the DB');
 }

 function storeInDB($temperature, $humidity){
  $query = "insert into dht11 set humidity='".$humidity."', temperature='".$temperature."'";
  $result = mysqli_query($this->link,$query) or die('Errant query:  '.$query);
 }

}
if($_GET['temperature'] != '' and  $_GET['humidity'] != ''){
 $dht11=new dht11($_GET['temperature'],$_GET['humidity']);
}
?>

PS。当我在浏览器http://localhost/dht.php?temperature=99&humidity=99中写信时新值在我的数据库中，因此我认为此.php代码可以正常工作。

ESP8266无法将数据发送到本地数据库（XAMPP）
