java - 安卓无法发送邮件

Question

我正在创建一个应用程序，它从编辑文本中获取输入并根据信息发送邮件。我正在使用 Http post 来执行此操作，我想与 Php 脚本进行通信以发送邮件请看看我的代码..

PHP 脚本

<?php
   $name = $_POST['name'];
   $to = $_POST['to'];
   $from = $_POST['from'];
   $subject = $_POST['subject'];
   $message = "From: ".$name."\r\n";
   $message .= $_POST['message'];
   $headers = "From:" . $from;
   mail($to,$subject,$message,$headers);
?>

Answer 1

将协议(protocol)添加到 URI 的 String 表示形式之前。

所以应该是:“http://www.dolphin123.net78.net/mailer.php”

您可以在上面的网址前面添加 http://
