我甚至不明白的代码，但我的想法，当我试图发布数据网络它不工作，我不知道什么是错发送使用Arduino的GSM模块的数据网络与它我正在获取网络内容，但我不能发布数据到网络我试过既得到和发布方法非他们给我带来好运使用GPRS

我使用了相同的代码，它工作。我只是想要你输入相同的数据。你可以解释一下你在上面代码中使用的webhost的url。 – Billa

你的http请求有一些错误 – Billa

你在你的代码中提出的http请求有一些错误。你不能像你那样从arduino请求。

当使用000webhost数据库时，最好的办法就是利用PHP。你可以通过选择文件管理器上传PHP文件，然后选择“现在上传文件”。在那里有一个名为“public_html”的文件夹，它是PHP代码将被上传。

现在就在这里做你想做的事情。你想创建一个PHP代码，当php代码的URL被请求时，它将执行数据库的插入操作。然后你可以从arduino请求这个链接进行插入。

的PHP代码是（请在代码中所提供的地点提供您的用户名，密码，DBNAME，表名，字段名，并上传它，因为我上面说的）：

<?php 
$servername = "localhost"; 
$username = "provide your username here"; 
$password = "password here"; 
$dbname = "database name here"; 

// Create connection 
$conn = mysqli_connect($servername, $username, $password, $dbname); 
// Check connection 
if (!$conn) { 
    die("Connection failed: " . mysqli_connect_error()); 
} 



$sql = "INSERT INTO table_name (column_name) VALUES ('".mysqli_real_escape_string($conn,$_GET['sensor1'])."')"; 

if (mysqli_query($conn, $sql)) { 
    echo "New record created successfully"; 
} else { 
    echo "Error: " . $sql . "<br>" . mysqli_error($conn); 
} 

mysqli_close($conn); 
?>

获取的URL上传的PHP代码（右键单击上传的文件并单击查看，然后在浏览器中复制URL）。你可以在你的Arduino草图中使用它。

你的arduino代码应该看起来像（这个草图中的URL不完整，取而代之的是我上面说的[http://afridiofkh.000webhostapp.com/phpfilename.php这是一个要被替换的东西。从http开始直到标记被替换]）：

这将执行插入操作，因为您需要.PHP很容易，因为它可以用来扩展操作。
