在 Android 项目上找不到证书路径的信任锚

Question

我有一个 Android 项目，它在我的测试环境中运行良好，带有测试环境证书。现在，我必须将此应用程序连接到客户端的 UAT 环境而不是测试环境。从客户的网站上，我下载了公共证书并将其添加到 Android 应用程序中，并替换了测试环境证书。当我测试应用程序时，出现以下错误。

这个错误是什么意思？是关于服务器端配置的错误吗？我应该将此证书添加到 Android 操作系统的受信任证书中吗？

编辑：从客户网站下载的证书是 CA 证书。不是自签名证书。

我认为您需要在 res/xml 中创建一个 network_security_config.xml 并且还需要对其进行配置。例如：

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
  <base-config>
    <trust-anchors>
        <certificates src="@raw/certificate_name"/>
        <certificates src="system"/>
    </trust-anchors>
  </base-config>

在此之后，您应该将 network_security_config 添加到 AndroidManifest

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