Question

我正在尝试使用PH + MySQL通过Android应用程序插入数据，我正在使用phpMyAdmin，但每次连接都被拒绝。

我的IP是127.0.0.1。我在localServer内的目录（如WAMP，XAMPP）android_connect。在Android连接中，我有一个名为create_product.php。

的PHP文件

    <?php

    /*
     * Following code will create a new product row
     * All product details are read from HTTP Post Request
     */

    // array for JSON response
    $response = array();

    // check for required fields
    if (isset($_POST['name']) && isset($_POST['price']) && isset($_POST['description'])) {

        $name = $_POST['name'];
        $price = $_POST['price'];
        $description = $_POST['description'];

        // include db connect class
        require_once('db_connect.php');

        // connecting to db
        $db = new DB_CONNECT();

        // mysql inserting a new row
        $result = mysql_query("INSERT INTO products(name, price, description) VALUES('$name', '$price', '$description')");

        // check if row inserted or not
        if ($result) {
            // successfully inserted into database
            $response["success"] = 1;
            $response["message"] = "Product successfully created.";

            // echoing JSON response
            echo json_encode($response);
        } else {
            // failed to insert row
            $response["success"] = 0;
            $response["message"] = "Oops! An error occurred.";

            // echoing JSON response
            echo json_encode($response);
        }
    } else {
        // required field is missing
        $response["success"] = 0;
        $response["message"] = "Required field(s) is missing";

        // echoing JSON response
        echo json_encode($response);
    }
  ?>

我的127.0.0.1是

对于连接我也使用create_product.php和端口，但它不起作用。错误是add_product.xml。

我该如何解决？

Answer 1

http://myipaddress.com返回您的外部IP地址，而不是您本地主机的IP。如果您使用MAC或Linux，请在终端中使用ifconfig，如果是Windows，请在命令提示符中使用“ipconfig”。 IP地址通常在192.x.x.x或类似的地方。

确保您的笔记本电脑和Android移动设备位于同一网络中。并检查您是否已在清单中声明了互联网权限

Answer 2

我正在使用本地php服务器，所以我需要像这样设置我的IP

http://10.0.2.2/android_connect/create_product.php"

它＆＃39;完美地解决我的错误。

连接被拒绝
