在 android 中使用 AsyncTask 将数据发送到 mySQL

Question

我确实有一个完整的堆，所以我的 gc 说我并且什么都不会发送 "GC_CONCURRENT 释放 277K，10% 释放 8120K/8967K，暂停 13ms+5ms，共 47ms"

我想使用php、http-Post 和AsyncTask 将一些数据从EditText 发送到mySQL，但找不到错误。

插入.php

            $link = mysql_connect("www.host.de", "user" , "pw");

        } else{
            echo "Connected to MySQL<br>";
        }

        // benutze Datenbank db
        $db_selected = mysql_select_db('db', $link);
        if (!$db_selected) {
            die ('Kann db nicht benutzen : ' . mysql_error());

PHP 中的参数名称应与您从 android 传递的参数名称匹配。

在 insert.php

中更改它

        $username = $_REQUEST['reg_fullname'];  
        $address = $_REQUEST['reg_address'];
        $postcode = $_REQUEST['reg_postcode'];
        $town = $_REQUEST['reg_town'];
        $country = $_REQUEST['reg_country'];
        $password = $_REQUEST['reg_password'];
        $motherbornin = $_REQUEST['reg_motherbornin'];
        $mail = $_REQUEST['reg_mail'];

到

        $username = $_REQUEST['name'];  
        $address = $_REQUEST['address'];
        $postcode = $_REQUEST['postcode'];
        $town = $_REQUEST['town'];
        $country = $_REQUEST['country'];
        $password = $_REQUEST['password'];
        $motherbornin = $_REQUEST['motherbornin'];
        $mail = $_REQUEST['mail'];
