离子“ERR_CLEARTEXT_NOT_PERMITTED”答案

【问题标题】：Ionic "ERR_CLEARTEXT_NOT_PERMITTED"离子“ERR_CLEARTEXT_NOT_PERMITTED”
【发布时间】：2020-07-24 06:59:21
【问题描述】：

我在将 Ionic 应用程序部署到 Android 时遇到问题，特别是我的 Arcgis 嵌入式地图。我收到错误“net::ERR_CLEARTEXT_NOT_PERMITTED”

经过研究，我发现这可能是因为地址是 HTTP::// 而不是 HTTPS::// 但即使在遵循其他人更改 AndroidManifest 的解决方案之后

android:usesCleartextTraffic="true"

我仍然遇到同样的错误。因为这是一个嵌入式链接，我无法将其更改为 https::// 我什至试图删除

android:networkSecurityConfig="@xml/network_security_config"

但仍然收到相同的错误。该地图在从浏览器运行时运行良好，但一旦部署到 android 就会中断。生病链接下面的文件

Config.xml 在这里我尝试在应用程序中添加 android:usesCleartextTraffic="true" 行，但没有成功。

我不确定从这里去哪里如何让它工作。由于这是我的应用程序的重要组成部分，我真的需要它来运行。

【问题讨论】：

您是否在edit-config 中添加了<application android:usesCleartextTraffic="true" /> 到config.xml？

标签： android html cordova ionic-framework arcgis

【解决方案1】：

我通过更改我的 Config.xml 并使用此代码更新它解决了我的问题。

<access origin="*" />
    <edit-config file="app/src/main/AndroidManifest.xml" mode="merge" target="/manifest/application">
        <application android:usesCleartextTraffic="true" />
    </edit-config>
    <allow-navigation href="*" />

并从 Config 和我的 AndroidManifest.xml 中删除

android:networkSecurityConfig="@xml/network_security_config"

【讨论】：

【解决方案2】：

将<application android:usesCleartextTraffic="true" /> 添加到config.xml 内edit-config。

<platform name="android">
    <edit-config file="app/src/main/AndroidManifest.xml" mode="merge" target="/manifest/application" xmlns:android="http://schemas.android.com/apk/res/android">
          <application android:usesCleartextTraffic="true" />
          <application android:networkSecurityConfig="@xml/network_security_config" />
    </edit-config>
    ...
</platform>

【讨论】：

【解决方案3】：

将纯数据传递到不安全的 URL 时可能会导致此问题。在将<application android:usesCleartextTraffic="true" /> 添加到config.xml 之前，请检查您是否可以将请求作为https，而不是http。

【讨论】：

【解决方案4】：

这是因为不允许使用明文。

但解决方法很简单。

在文件夹 resorces/android/xml 中有一个文件 network_security_config.xml

请添加本地域或不安全域或 IP。

例如：

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <domain-config cleartextTrafficPermitted="true">
        <domain includeSubdomains="true">localhost</domain>
        <domain includeSubdomains="true">192.168.0.7</domain>
        <domain includeSubdomains="true">192.168.0.12</domain>
        <domain includeSubdomains="true">10.10.1.112</domain>
    </domain-config>
</network-security-config>

那么，请再跑一次……就是这样。
