为 Restful 增加 SSL 证书，保证数据在传输中安全。

证书有两类，一类是授信办颁发构的证书，另一类是自己创建的证书，两种证书使用效果上一样。

授信证书的跟证书默认已经安装在操作系统，浏览器中，访问时会出现锁头跟绿色标识。这种证书是需要购买的，因为这些证书厂商每年都要像微软，苹果等等操作系统厂商支付一定费用。

最近火狐公司发表声明，将取消“沃通”根证书，这就意味着这所有沃通用户都会变成红叉叉。

对于内部业务不需要对外提供服务，例如Restful 服务，我见意自己创建证书，如果你需要让浏览器地址栏变成绿色，只需将你的根证书导入进去就可可以了。

21.1.3. Get https 接口

环境 Nginx SSL(openssl自颁发)，nginx 通过proxy_pass连接 Tomcat

下面是 nginx 配置

server {
    listen 443 ssl spdy;
    server_name api.netkiller.cn;

    ssl_certificate /etc/nginx/ssl/api.netkiller.cn.crt;
    ssl_certificate_key /etc/nginx/ssl/api.netkiller.cn.key;
    ssl_session_cache shared:SSL:20m;
    ssl_session_timeout 60m;
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;

    charset utf-8;
    access_log  /var/log/nginx/api.netkiller.cn.access.log;
    error_log  /var/log/nginx/api.netkiller.cn.error.log;

    location / {
        proxy_pass      http://127.0.0.1:7000;
        proxy_http_version 1.1;
        proxy_set_header    X-Forwarded-For $proxy_add_x_forwarded_for;
    }

}

21.1.3. HTTPS

21.1.3.1. Get https 接口

环境 Nginx SSL(openssl自颁发)，nginx 通过proxy_pass连接 Tomcat

下面是 nginx 配置

server {
    listen 443 ssl spdy;
    server_name api.netkiller.cn;

    ssl_certificate /etc/nginx/ssl/api.netkiller.cn.crt;
    ssl_certificate_key /etc/nginx/ssl/api.netkiller.cn.key;
    ssl_session_cache shared:SSL:20m;
    ssl_session_timeout 60m;
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;

    charset utf-8;
    access_log  /var/log/nginx/api.netkiller.cn.access.log;
    error_log  /var/log/nginx/api.netkiller.cn.error.log;

    location / {
        proxy_pass      http://127.0.0.1:7000;
        proxy_http_version 1.1;
        proxy_set_header    X-Forwarded-For $proxy_add_x_forwarded_for;
    }

}

下面是 Java 程序

				package cn.netkiller.example;

import java.io.IOException;
import java.security.KeyManagementException;
import java.security.KeyStoreException;
import java.security.NoSuchAlgorithmException;

import org.apache.http.HttpEntity;
import org.apache.http.ParseException;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.conn.ssl.SSLConnectionSocketFactory;
import org.apache.http.conn.ssl.TrustSelfSignedStrategy;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.ssl.SSLContextBuilder;
import org.apache.http.util.EntityUtils;

public class NginxAndOpenSSLAndTomcatAndHttpclient {
	public static void main(String[] args) throws ParseException, IOException, NoSuchAlgorithmException, KeyStoreException, KeyManagementException {
		SSLContextBuilder builder = new SSLContextBuilder();
		builder.loadTrustMaterial(null, new TrustSelfSignedStrategy());
		SSLConnectionSocketFactory sslFactory = new SSLConnectionSocketFactory(builder.build());
		CloseableHttpClient httpclient = HttpClients.custom().setSSLSocketFactory(sslFactory).build();

		HttpGet httpGet = new HttpGet("https://neo:netkiller@api.netkiller.cn/v1/news/today.json");
		CloseableHttpResponse response = httpclient.execute(httpGet);
		try {
			System.out.println(response.getStatusLine());
			HttpEntity entity = response.getEntity();
			String responseBody = EntityUtils.toString(entity, "UTF-8");
			System.out.println(responseBody.toString());
		} finally {
			response.close();
		}
	}
}
