java - 如何修复 'Cleartext HTTP traffic to x not permitted'

Question

我正在尝试向 http 服务器发出 post 请求，但是当我尝试获取输入流时，我收到错误 java.io.IOException: Cleartext HTTP traffic to x not permitted
我已经试过把 android:usesCleartextTraffic="true"在我的 list 中，以及进行网络安全配置并将 android:targetSandboxVersion 设置为 1

app/src/main/res/xml/network_security_config.xml

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <domain-config cleartextTrafficPermitted="true">
        <domain includeSubdomains="true">Server adress</domain>
    </domain-config>
</network-security-config>

应用程序/src/main/AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.packagename"
    android:targetSandboxVersion="1">

    <uses-permission android:name="android.permission.INTERNET"/>

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme"
        android:usesCleartextTraffic="true"
        android:networkSecurityConfig="@xml/network_security_config"
        >
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

Logcat 输出

D/NetworkSecurityConfig: Using Network Security Config from resource network_security_config debugBuild: true
W/System.err: java.io.IOException: Cleartext HTTP traffic to x not permitted
W/System.err:     at com.android.okhttp.HttpHandler$CleartextURLFilter.checkURLPermitted(HttpHandler.java:124)

任何帮助，将不胜感激

Answer 1

尝试仅使用

android:usesCleartextTraffic="true"

删除这个 2

android:targetSandboxVersion="1"
android:networkSecurityConfig="@xml/network_security_config"

我的只是使用 android:usesCleartextTraffic="true"在任何 API 中工作
