Question

我是新手。我想将我的Android应用程序连接到wampserver数据库。我找到了关于这个link的教程，但是我应该在哪里找到我在wampserver中的serverUrl？它应如下所示：private final String serverUrl = "your path here"那么我在哪里可以找到"your path here"？

这是我的代码：

MainActivity.java

        loginButton.setOnClickListener(new View.OnClickListener() {

                enteredUsername = username.getText().toString();
                String enteredPassword = password.getText().toString();

                if(enteredUsername.equals("") || enteredPassword.equals("")){

                    return;

                // request authentication with remote server4
                AsyncDataClass asyncRequestObject = new AsyncDataClass();

我正在使用带有user="root"和password=""

的WampServer

Answer 1

感谢 @ e4c5 （针对建议）和 @Laser 的答案。

我解决了！

因此对于偶然发现此问题的其他人来说，检查一下！ ^ _ ^

转到 cmd ＆gt;＆gt;输入ipconfig＆gt;＆gt;然后查看 IPv4地址 ...

然后将其粘贴到private final String serverUrl = "your path here"

上

将your path here替换为http://192.168.1.8/android_user_api/index.php

谢谢你们！

快乐的编码！

Answer 2

＆＃34;路径＆＃34;可能是本地Web服务器的URL，即：

http://your_ip/your_path_to_your_php_script

Answer 3

您需要找到计算机的IPV4地址，在计算机中运行命令提示符（转到Windows启动按钮并启动typig cmd）并输入ipconfig并输入以查看计算机的IPV4地址。

在计算机上成功运行WAMP服务器会在系统托盘上显示绿色图标，单击该图标，弹出菜单，单击 put online 项。等待几秒钟来处理它的任务。

要在Android工作室模拟器中测试PHP MySQL的应用程序，只需输入地址http:\\IP Address\，然后在代码中输入PHP文件的路径。

例如：http:\\192.168.1.7\test\example.php

Answer 4

对我有用的解决方案是在我正在开发的android应用中使用10.0.2.2作为IP地址。

Android使用Android Studio和PHP进行Wamp服务器连接
