HTTP 请求
格式正确
正确的 HTTP POST 请求看起来像这样：
POST /url HTTP/1.1\r\n
Host example.com\r\n
Content-Type: application/x-www-form-urlencoded\r\n
Content-Length: 7\r\n
\r\n
foo=bar
这将发送 bar 作为 foo 的值。在 GET 请求中，您可以将其添加到 URL (/url/?foo=bar)，但 POST 请求不能像这样工作：您必须添加消息正文。
Content-Length 应该是正文中的字符数（这里：foo=bar，所以 7 个字符）。 Content-Type 和 Content-Length 字段是执行您想要的操作所必需的。主机字段在任何 HTTP/1.1 请求中都是必需的。
请注意，换行符是 \r\n。幸运的是，Arduino's println() 添加了回车符 return \r 和换行符 \n。但是，您应该确保不要使用 print() ，除非您想在同一行上继续。所以这是一个工作示例：
Arduino 工作示例
client.println("POST /sample.php HTTP/1.1");
client.println("Host: tmm.site50.net");
client.println("Content-Type: application/x-www-form-urlencoded");
client.println("Content-Length: 7");
client.println("");
client.println("temp=50");
这将发送 50 作为温度。
PHP后端
将数据存储在文件中
那么您可能希望将发送的数据保存在服务器上。为此，您从 $_POST 超全局获取信息，并将其保存在文件中：
<?php
$handle = fopen('temp.log', 'w');
fwrite($handle, date('d/m/Y H:i:s') . " - " . $_POST['temp']) . "\n";
fclose($handle);
?>
这将以写入模式打开 temp.log（请参阅 fopen()), then writes a timestamp and the current value to that file (see fwrite()), and closes the handle (see fclose()）。该文件看起来像这样：
30/01/2015 09:12:40 - 50
您只需转到 http://tmm.site50.net/temp.log 即可查看文件。
日志记录
每次Arduino发送一个请求，旧的结果都会被覆盖。或者，您可能想要 log 数据，并添加新行而不是覆盖旧数据。然后，在 fopen() 中使用 a（附加）模式而不是 w（写入）：
$handle = fopen('temp.log', 'a');
这将自动在文件末尾追加新行。
权限
根据您服务器上的权限，您可能需要先创建 temp.log，然后 PHP 才能写入。
