我有一个类,将从https服务器下载文件。当我运行它时,它返回了很多错误。我的证书好像有问题。是否可以忽略客户机-服务器身份验证?如果有,怎么做?

当前回答

如果在maven或maven的TestNG中得到这个错误:

从目标网站下载证书并在您的计算机上安装证书(使用上面建议的keytool,或在windows上) 将以下内容添加到maven参数(命令行和/或IDE): -Djavax.net.ssl.trustStore = C: \ \用户me.keystore -Djavax.net.ssl.trustStorePassword = X 其中X是在keytool步骤中使用的密码。

注:c:\用户\我密钥存储库也应该设置为与您的机器匹配。 例如:

mvn -ea -Dtestng.dtd.http=true  -Djavax.net.ssl.trustStore=C:\Users\me\.keystore -Djavax.net.ssl.trustStorePassword=X -Dmaven.wagon.http.ssl.insecure=true -Dmaven.wagon.http.ssl.allowall=true -Dmaven.wagon.http.ssl.ignore.validity.dates=true -Dcucumber.features=src/test/resources -Dcucumber.glue=com.myapp -Dcucumber.filter.tags="@MY_TEST"

其他回答

在我的例子中,我的密钥存储库和信任存储库都具有相同的证书,因此删除信任存储库有帮助。有时,如果您有多个证书副本,则证书链可能会成为问题。

我遵循的简单步骤。

问题:我试图连接到一个端点(https://%s.blob.core.windows.net)使用一个简单的java类(主要方法)。

我遇到了这个认证问题就像上面提到的。

解决方案:

使用浏览器(chrome)获取证书。为此,在浏览器中粘贴端点URL并输入。现在你会看到一个锁图标,点击它——>证书——>细节——>拷贝到文件——>下载它。 以admin的身份打开cmd(我使用的是windows),然后导航到你下载了.cer文件的目录。

3.(可选)如果你在同一台机器上使用多个JDK,那么修改你的JDK版本,使其与你在应用程序中使用的版本一致。

现在使用下面的命令

导入mycertificate -keystore "C:\程序 文件\Java\jdk-11.0.5\lib\security\cacerts" -file myurlcrt.cer

给出默认密码:changeit 相信这个证书:是的

这样就做完了。

谢谢!

我在赛门铁克的有效签名通配符证书上也遇到了同样的问题。

首先尝试使用-Djavax.net.debug=SSL运行java应用程序,看看到底发生了什么。

我最终导入了导致证书链中断的中间证书。

我从赛门铁克下载了缺少的中间证书(您可以在ssl握手日志中看到缺少证书的下载链接:在我的例子中是http://svrintl-g3-aia.verisign.com/SVRIntlG3.cer)。

我在java密钥库中导入了证书。导入中间证书后,我的通配符ssl证书终于开始工作:

keytool -import -keystore ../jre/lib/security/cacerts -trustcacerts -alias "VeriSign Class 3 International Server CA - G3" -file /pathto/SVRIntlG3.cer

仅适用于Windows,请遵循以下步骤:

In Chrome go to settings. In Settings click show advance settings. Under HTTPS/SSL Click on Manage Certificates. Export Your Certificate. In Windows searchs (Pressing windows key on keyboard) type java. Select (Configure Java) Option Which will open Java Control Panel Select Security tab in Java Control Panel Select Manage Certificates Click Import Under (User) tab selected and certificate type as (Trusted Certificates) Click import button and browse to downloaded certificate and import it.

确保https://176.66.3.69:6443/有有效的证书。 你可以通过浏览器检查它首先,如果它在浏览器中工作,它将在java中工作。

这对我很有用
