Nginx weblogic SSL 雙向驗(yàn)證服務(wù)器獲取瀏覽器證書

Nginx 開啟了 SSL 雙向驗(yàn)證, weblogic 也開啟了雙向驗(yàn)證。瀏覽器訪問 Nginx、Nginx 訪問 webogic 都需要證書，Nginx 配置如下：

    server {
        error_log     logs/info.log info;
        listen       9105 ssl default_server;
        server_name  192.168.7.163;

        #證書文件
        ssl_certificate     C:/OpenSSL/bin/server/server-cert.pem;
        #私鑰文件
        ssl_certificate_key C:/OpenSSL/bin/server/server-key.pem;
        # 開啟 ssl 雙向認(rèn)證
        #ssl_client_certificate C:/OpenSSL/bin/test/ca-cert.pem; 
        ssl_client_certificate C:/OpenSSL/bin/ca/ca-cert.pem;
        ssl_verify_client on;
        ssl_prefer_server_ciphers on;
        #設(shè)置長連接
        keepalive_timeout   70;
    location /portal1 {
        proxy_set_header  X-Real-IP  $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_ssl_certificate     C:/OpenSSL/bin/test/user-cert.pem;
        proxy_ssl_certificate_key C:/OpenSSL/bin/test/user-key.pem;
        proxy_set_header X-Forwarded-Proto https; 
        proxy_ssl_protocols TLSv1 SSLv3;
        proxy_http_version 1.1;
        proxy_ssl_ciphers DEFAULT:!DH; 
        proxy_ssl_server_name on;
        proxy_ssl_session_reuse off;
        proxy_set_header X-SSL-Client-Cert $ssl_client_cert;
        proxy_set_header Client-Cert $ssl_client_cert;
        proxy_pass https://192.168.7.163:20021/portal;
    }

目前問題是：weblogic 端怎樣獲取瀏覽器訪問 nginx 的證書而不是 Nginx 反向代理 weblogic 時(shí)通過如下配置配置的固定的證書

proxy_ssl_certificate     C:/OpenSSL/bin/test/user-cert.pem;
proxy_ssl_certificate_key C:/OpenSSL/bin/test/user-key.pem;

java 中獲取證書代碼如下, 這段代碼獲取的始終是 Nginx 反向代理配置的證書而不是瀏覽器訪問 Nginx 的證書：

X509Certificate[] certs=(X509Certificate[])request.getAttribute("javax.servlet.request.X509Certificate");
