我正在尝试将图像上传到后备在线存储。我使用backblaze java-sdk进行了调用。尝试上传图片时,出现以下错误:

2020-04-25 11:19:45,443 ERROR [stderr] (default task-10) <B2Exception 904 io_exception: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target talking to https://api.backblazeb2.com/b2api/v2/b2_authorize_account>


我找不到有关在backblaze网站上添加任何证书的必要性的任何信息。

经过互联网上的研究,我发现我应该?将backblaze证书添加到我的Java安装的信任库中。因此,我从https://www.backblaze.com/使用chrome(保存为.cer文件)下载了证书,并使用以下命令将其安装到了我的Java中:

keytool -import -alias backblaze -keystore "%JAVA_HOME%/jre/lib/security/cacerts" -storepass <password> -keypass changeit -file .../backblaze.cer -noprompt


执行此命令时,我也可以看到它:

keytool -list -v -keystore "%JAVA_HOME%/jre/lib/security/cacerts"


有一个别名条目:backblaze

在我的jboss启动过程中使用VM选项-Djavax.net.debug=ssl,我可以看到Java使用了正确的信任库并找到了带有backblaze别名的条目:

因此,我认为Java进程可以找到正确的证书,但是当我无法连接api.backblaze端点时,会收到握手异常:

我是SSL新手,但我不明白自己在做什么错。我下载了错误的证书(并且api.backblaze有一个额外的证书,我必须安装)或我配置的Java信任库错误。

最佳答案

好吧,经过一番挣扎之后,我发现我使用了错误的vertical。我必须从api.backblazeb2.com下载证书并安装它:

下载:

keytool -printcert -sslserver api.backblazeb2.com:443 -rfc > api.backblazeb2.cer


安装:

keytool -import -alias api.backblazeb2 -keystore "%JAVA_HOME%/jre/lib/security/cacerts" -storepass changeit -keypass changeit -file api.backblazeb2.cer -nopro
mpt


为确保此后重启Java进程。
