Tomcat - 设置 HTTP 摘要认证

在 Tomcat 中设置 HTTP 摘要认证的示例

在 Tomcat 中设置摘要认证与设置基本认证几乎一样，差别在于配置 web.xml 时，<login-config/> 元素在指定认证方法时，基本认证设置 auth-method 为 BASIC，而摘要认证设置 auth-method 为 DIGEST：

<login-config>
    <auth-method>DIGEST</auth-method>
    <realm-name>hueyhome</realm-name>
</login-config>

测试：

a) 无认证信息请求

C:\Users\huey> curl -I http://localhost:8080/helloweb/home/index.html
HTTP/1.1 401 Unauthorized
Server: Apache-Coyote/1.1
Pragma: No-cache
Cache-Control: no-cache
Expires: Thu, 01 Jan 1970 08:00:00 CST
WWW-Authenticate: Digest realm="hueyhome", qop="auth", nonce="1463129892972:deeaa87bec6be4057899dac852625e9c", opaque="AECB8C2E17E7F66CF7905F638B7463EA"
Content-Type: text/html;charset=utf-8

b) 正确认证信息且该用户无指定资源的访问权限

C:\Users\huey>curl -I --digest -u "all:all" http://localhost:8080/helloweb/home/index.html
HTTP/1.1 401 Unauthorized
Server: Apache-Coyote/1.1
Pragma: No-cache
Cache-Control: no-cache
