android - 我正在尝试使用 wamp 连接到数据库，但它会在 android studio 中引发 file not found 异常。如何解决这个问题？

Question

所以我已经配置了 php 文件，我的 wamp 试图连接到数据库，但它抛出了一个错误，我什至保留了网络安全证书，但仍然抛出了错误。

尝试过的解决方案 1. 添加了 android:usesCleartextTraffic="true"。2.将地址更改为ipv4地址。3.增加安全文件Manifestxml：

android:networkSecurityConfig="@xml/network_security_config";

network_security_config.xml：

<?xml version="1.0" encoding="utf-8"?>
<network-security-config xmlns:android="http://schemas.android.com/apk/res/android">
<debug-overrides>
    <trust-anchors>
        <certificates src="user" overridePins="true"/>
    </trust-anchors>
</debug-overrides>
</network-security-config>

错误：

W/IInputConnectionWrapper: finishComposingText on inactive InputConnection
D/NetworkSecurityConfig: Using Network Security Config from resource network_security_config debugBuild: true
W/System.err: java.io.FileNotFoundException: http://10.0.2.2/login.php

http://10.0.2.2/login.php

而是使用 10.0.2.2 使用您的 IPv4 地址并添加您的端口号虽然对我有用
