java如何修复“不允许x的明文HTTP通信”

1 月，3 周 Questions & Answers 19981

我试图向http服务器发出post请求，但是当我试图获取输入流时，我得到了错误java.io.IOException: Cleartext HTTP traffic to x not permitted

我已经尝试将安卓:usesCleartextTraffic="true"放在我的清单中，并进行了网络安全配置，将安卓:targetSandboxVersion设置为1

app/src/main/res/xml/network\u security\u 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>

app/src/main/AndroidManifest。xml

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

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

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

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

对数输出

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.安卓.okhttp.HttpHandler$CleartextURLFilter.checkURLPermitted(HttpHandler.java:124) 
W/System.err:     at com.安卓.okhttp.internal.huc.HttpURLConnectionImpl.execute(HttpURLConnectionImpl.java:462)
W/System.err:     at com.安卓.okhttp.internal.huc.HttpURLConnectionImpl.getResponse(HttpURLConnectionImpl.java:411)
W/System.err:     at com.安卓.okhttp.internal.huc.HttpURLConnectionImpl.getInputStream(HttpURLConnectionImpl.java:248)

任何帮助都将不胜感激

试着使用just

android:usesCleartextTraffic="true"

删除此2

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

我的应用程序可以在任何API中使用android:usesCleartextTraffic=“true”

# 2 楼答案

不要这样做，这可能是获取运行时错误做最简单的方法；转到android本机项目，在这里您可以看到属性单击此处，然后获取AssemblyInfo。cs文件，然后在下面编辑此部分

[程序集：应用程序（UsesCleartextTraffic=true）]

下面是我的代码示例：-

 using System.Reflection;
    using System.Runtime.CompilerServices;

    using System.Runtime.InteropServices;

    using Android.App;

    // General Information about an assembly is controlled through the following 
    // set of attributes. Change these attribute values to modify the information
    // associated with an assembly.
    [assembly: AssemblyTitle("ZATWEBO.Android")]
    [assembly: AssemblyDescription("")]
    [assembly: AssemblyConfiguration("")]
    [assembly: AssemblyCompany("")]
    [assembly: AssemblyProduct("ZATWEBO.Android")]
    [assembly: AssemblyCopyright("Copyright ©  2014")]
    [assembly: AssemblyTrademark("")]
    [assembly: AssemblyCulture("")]
    [assembly: ComVisible(false)]

    // Version information for an assembly consists of the following four values:
    //
    //      Major Version
    //      Minor Version 
    //      Build Number
    //      Revision
    //
    // You can specify all the values or you can default the Build and Revision Numbers 
    // by using the '*' as shown below:
    // [assembly: AssemblyVersion("1.0.*")]
    [assembly: AssemblyVersion("1.0.0.0")]
    [assembly: AssemblyFileVersion("1.0.0.0")]

    // Add some common permissions, these can be removed if not needed
    [assembly: UsesPermission(Android.Manifest.Permission.Internet)]
    [assembly: UsesPermission(Android.Manifest.Permission.WriteExternalStorage)]
    [assembly: Application(UsesCleartextTraffic = true)]

注意：此更改只需要android 9 Pie或更高版本

# 3 楼答案

我向Android清单文件添加了以下代码：

    <?xml version="1.0" encoding="utf-8"?>
    <network-security-config>
        <base-config>
            <trust-anchors>
                <certificates src="system">
                </certificates>
            </trust-anchors>
        </base-config>
        <domain-config cleartextTrafficPermitted="true">
            <domain includeSubdomains="true">http://YourURL/api/</domain>
        </domain-config>
    </network-security-config>

# 4 楼答案

在项目res/xml/security\u config中创建一个文件。xml-

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <domain-config cleartextTrafficPermitted="true">
        <domain includeSubdomains="true">Your URL(ex: 127.0.0.1)</domain>
    </domain-config>
</network-security-config>

AndroidManifest.xml -

<?xml version="1.0" encoding="utf-8"?>
<manifest ...>
    <uses-permission android:name="android.permission.INTERNET" />
    <application
        ...
        android:networkSecurityConfig="@xml/security_config"
        ...>
        ...
    </application>
</manifest>

另外，如果您在中有android:targetSandboxVersion，则将其减少为1

# 5 楼答案

可能是你弄错了。这是从另一个来源获得的正确格式

 <?xml version="1.0" encoding="utf-8"?>
 <network-security-config>
<domain-config cleartextTrafficPermitted="true">
    <domain includeSubdomains="true">Your URL(ex: 127.0.0.1)</domain>
</domain-config>

AndroidManifest。xml-

<?xml version="1.0" encoding="utf-8"?>
<manifest ...>
 <uses-permission android:name="android.permission.INTERNET" />
 <application
    ...
    android:networkSecurityConfig="@xml/network_security_config"
    ...>
 </application>
</manifest>

如果在中有android:targetSandboxVersion，则将其减少为1
