如何通过 GET REST API 调用传递 ssl 证书

Question

我有一个在不同机器上运行的网络服务器。我能够使用邮递员客户端并加载 cert.pem 和 key.pem 文件并成功执行获取请求。

现在我想在 Java 中以编程方式执行此操作。为此，我将 PKCS12 添加到密钥库，如下所示：

keytool -importkeystore -destkeystore keystore.jks -srcstoretype PKCS12 -srckeystore keystore.p12

keytool -list -keystore keystore.jks

现在在代码中我这样做了：

String url = "https://localhost:9443/server/api/v1/"+id+"/_history/"+history;
URL obj = new URL(url);
System.setProperty("javax.net.ssl.keyStore", "/Users/rc/Downloads/test101/jks/keystore.jks");

System.setProperty("javax.net.ssl.keyStorePassword", "asdfgh");
System.setProperty("javax.net.ssl.keyStoreType", "JKS");            


HttpURLConnection con = (HttpURLConnection) obj.openConnection();

    con.setRequestMethod("GET");

        //add request header
con.setRequestProperty("Content-Type", "application/json");
con.setRequestProperty("Accept", "application/json");

int responseCode = con.getResponseCode();       
System.out.println("\nSending 'GET' request to URL : " + url);      
System.out.println("Response Code : " + responseCode);

我得到：

解决方案：

我必须生成 jssecacerts 并将其保存在特定位置。我缺少的部分在此链接中：

您正在尝试通过http:// 进行连接，但应使用https://。查看您的网址：

String url = "http://localhost:9443/server/api/v1/"+id+"/_history/"+history;

“java.net.SocketException: Unexpected end of file”表示服务器接受然后关闭连接而不发送响应。我相信用于 HTTPS 连接的端口 9443 尚未准备好接受 HTTP 连接。
