通过 ADB 安装自签名证书

Question

我正在尝试通过ADB安装自签名证书(由Charles创建( 我已将其推送到/sdcard/xxx.pem ，然后无法使用我能找到的浏览器打开它，并且由于设备删除了设置应用程序，因此我无法在设置应用程序下安装证书。 然后我搜索并尝试

am start -n com.android.certinstaller/.CertInstallerMain -a android.intent.action.VIEW -t application/x-x509-ca-cert file:///sdcard/test.cer

但刚刚显示

我不熟悉这个com.android.certinstaller应用程序，是否有任何参考如何使用它来安装证书？

Answer 1

请尝试以下操作：

adb shell am start -n com.android.certinstaller/.CertInstallerMain -a android.intent.action.VIEW -t application/x-x509-ca-cert -d file:///sdcard/test.cer

如果扔 com.android.certinstaller E/CertInstaller：无法读取证书：java.io.FileNotFoundException：/sdcard/cer(权限被拒绝(

请根植您的设备并将 cer 推送到/system/etc/adb shell am start -n com.android.certinstaller/.CertInstallerMain -a android.intent.action.VIEW -t application/x-x509-ca-cert -d file:///system/etc/test.cer

Answer 2

如果收到"权限被拒绝"或"云找不到文件"，则需要确保文件可读。

chmod o+r /sdcard/test.cer

然后

adb shell am start -n com.android.certinstaller/.CertInstallerMain -a android.intent.action.VIEW -t application/x-x509-ca-cert -d file:///sdcard/test.cer
