【tomcat】HTTPS访问配置 + restful调用远程HTTPS绕过验证

 

 单向验证：

第一步： 生成key：

keytool -genkey -alias mykey -keyalg RSA -keystore d:/key/testkey

keytool -export -file d:/key/testkey.crt -alias mykey -keystore d:/key/testkey

 

由于是本地测试，请修改本地host文件C:\Windows\System32\drivers\etc\host

# localhost name resolution is handled within DNS itself.
#    127.0.0.1       localhost
#    ::1             localhost
127.0.0.1 www.xiaochangwei.com

这样就可以通过域名访问了

 

 

第二步：tomcat配置

<Connector port="8448" protocol="org.apache.coyote.http11.Http11Protocol" SSLEnabled="true"
               maxThreads="150" scheme="https" secure="true"
               clientAuth="false" sslProtocol="TLS" 
               keystoreFile="D:\key\testKey"  
               keystorePass="123456"/>

这里默认是注释掉的 请打开，根据需要可以修改默认的端口，默认端口为8443

 

在这里需要注意的是，在linux等非windows环境下，会提示 找不到key 或者秘钥过若等提示，在找不到秘钥时tomcat无法正常启动，秘钥过若页面不能正常访问

需解决两点，  

 ①把上面的key加一个后缀以便非windows环境识别

②增加秘钥的复杂度

完整配置如下：

<Connector port="443" protocol="HTTP/1.1" SSLEnabled="true"
               maxThreads="150" scheme="https" secure="true"
               clientAuth="false" sslProtocol="TLS" 
               keystoreFile="/opt/apache-tomcat-7.0.64/testkey.keystone"  
               keystorePass="123456" ciphers="TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256,TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA,TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384,TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA,TLS_RSA_WITH_AES_128_CBC_SHA256,TLS_RSA_WITH_AES_128_CBC_SHA,TLS_RSA_WITH_AES_256_CBC_SHA256,TLS_RSA_WITH_AES_256_CBC_SHA"/>

                 

 

 

第三步：发布项目

 

可以看见项目已经发布成功，且端口也可用，下面测试下端口情况

 

可以看出，都能正常访问，证明已经部署成功。

双向验证

 

复制代码
为服务器生成证书
keytool -genkey -v -alias server -keyalg RSA -keystore d:\key2\server.keystore -validity 36500

为客户端生成证书
keytool -genkey -v -alias client -keyalg RSA -storetype PKCS12 -keystore d:\key2\client.key.p12
导入客户端证书

让服务器信任客户端证书
 1.先把客户端证书到处为cer文件格式
 keytool -export -alias client -keystore d:\key2\client.key.p12 -storetype PKCS12 -storepass 123456 -rfc -file d:\key2\client.key.cer
 
 2.将客户端cer导入到服务器证书库
 keytool -import -v -file d:\key2\client.key.cer -keystore d:\key2\server.keystore
 
 3.查看安装结果
 keytool -list -keystore d:\key2\server.keystore
 
 让客户端信任服务器证书
 1.把服务器证书到处为cer文件
 keytool -keystore d:\key2\server.keystore -export -alias server -file d:\key2\server.cer
 
 2.在客户端安装服务器证书
 选择受信任的根证书颁发机构
 
 配置tomcat
 <Connector port="8443" protocol="org.apache.coyote.http11.Http11Protocol" SSLEnabled="true"
               maxThreads="150" scheme="https" secure="true"
               clientAuth="true" sslProtocol="TLS" 
               keystoreFile="D:\\key2\\server.keystore" keystorePass="123456"  
               truststoreFile="D:\\key2\\server.keystore" truststorePass="123456" />

HTTP接口的调用说白了无非就是根据地址，先建立链接，然后获取返回的信息或者发送请求数据过去，完成业务逻辑后关闭链接。

可以通过原生态的接口调用方式进行http接口的调用，http://www.cnblogs.com/xiaochangwei/p/5045264.html 也可以采用restful进行，

如果系统要调用的http接口众多，请采用restful统一管理，使代码更清晰

 

先说说接口调用时，怎么绕过https验证，即别人的项目是以https方式发布的，如果是双向验证，则需要证书密码等。

下面是参考别人的内容，地址：http://blog.csdn.net/noodies/article/details/17240805

受此启发，我们项目中使用的是restful，则直接修改初始化的httpclient就好了

下面代码就是restful风格进行http接口调用方式，请注意jar包的引入 RestTemplate 在spring-web.jar里面的

    }

由于是商业项目的代码，所以仅贴一部分代码，根据这个就可以完全掌握restful相关技术，需要解释下的是：

① frontInfo 是一个共通的参数对象，为保证接口调用方式统一，里面有各接口需要的参数名等，如ip，prot，url，method，username 等等......

② generateUrl 是根据共通参数对象及条件生成具体的url，如 https://www.xiaochangwei.com/http/web/getuser.do?username=xiaogege&age=28

③ generateHttpEntity 是根据具体的业务需要增加一些共通的header信息

④ exchange 就是具体的执行了，返回ResponseEntity<String>，然后根据具体的业务返回，进行解析

⑤ 调用后解析返回信息大致如下，解析其中的body

JSONObject object = JSONObject.parseObject(response.getBody().toString());
JSONObject userJson = JSONObject.parseObject(object.getString("user"));
String uuid = userJson.getString("id");

至此restful使用方式介绍完毕
