篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Eureka实战-4开启http basic权限认证相关的知识，希望对你有一定的参考价值。

在我们实际生产环境中，都需要考虑到一个安全问题，比如用户登录，又或者是eureka server，它对外暴露的有自己的rest API，如果没有安全认证，也就意味着别人可以通过rest API随意修改数据信息，这是一件非常恐怖的事情，这篇文章咱们详谈eureka server是如何开启认证，以及eureka client是如何配置鉴权信息。

1、eureka server工程

1.1、eureka server工程pom：

<!--加上文章头部的公共依赖-->

<dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
        </dependency>
　　　　　
　　　　 <!--权限依赖，只要pom文件有这个依赖，项目默认就已经开启了权限校验-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-security</artifactId>
        </dependency>
</dependencies>

<build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
</build>

 

1.2、eureka server工程启动类：

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

@SpringBootApplication
@EnableEurekaServer
public class EurkeaServerApplication 

    public static void main(String[] args) 
        SpringApplication.run(EurkeaServerApplication.class, args);

 

1.3、eureka server工程配置文件，路径：eureka-server\src\main\resources\

application-security.yml：

server:
  port: 8761

spring:
  security:
    basic:
      enabled: true
    user:
      name: admin
      password: Xk38CNHigBP5jK75
eureka:
  instance:
    hostname: localhost
  client:
    registerWithEureka: false
    fetchRegistry: false
    serviceUrl:
      defaultZone: http://$eureka.instance.hostname:$server.port/eureka/
  server:
      waitTimeInMsWhenSyncEmpty: 0
      enableSelfPreservation: false

application.yml：

spring:
  profiles:
    active: security

 

由于spring-boot-starter-security默认开启了CSRF校验，对于client端这类非界面应用来说，有些不合适，但是又没有配置文件的方式可以禁用，需要通过Java配置，进行禁用，如下：

import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;

/**
 * 关闭spring-boot-starter-security的CSRF校验
 */
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter 

    @Override
    protected void configure(HttpSecurity http) throws Exception 
        super.configure(http);
        http.csrf().disable();

 

1.4、启动eureka server工程，执行命令：

mvn spring-boot:run

打开命令行终端，执行： curl -i http://localhost:8761/eureka/apps

curl -i http://localhost:8761/eureka/apps
HTTP/1.1 401
Set-Cookie: JSESSIONID=554BCAF092D8D1ED3936C0CB09E91AF1; Path=/; HttpOnly
WWW-Authenticate: Basic realm="Realm"
X-Content-Type-Options: nosniff
X-XSS-Protection: 1; mode=block
Cache-Control: no-cache, no-store, max-age=0, must-revalidate
Pragma: no-cache
Expires: 0
X-Frame-Options: DENY
Content-Type: application/json;charset=UTF-8
Transfer-Encoding: chunked
Date: Fri, 04 Oct 2019 07:31:57 GMT

"timestamp":"2019-10-04T07:31:57.888+0000","status":401,"error":"Unauthorized","message":"Unauthorized","path":"/eureka/apps"

可以看出，没有传递Authenticate的header，返回401状态码。

 

下面使用http basic的账号密码传递Authenticate的header：

curl -i --basic -u admin:Xk38CNHigBP5jK75 http://localhost:8761/eureka/apps
HTTP/1.1 200
Set-Cookie: JSESSIONID=CF1C0DE56415626494EC539A654CC543; Path=/; HttpOnly
X-Content-Type-Options: nosniff
X-XSS-Protection: 1; mode=block
Cache-Control: no-cache, no-store, max-age=0, must-revalidate
Pragma: no-cache
Expires: 0
X-Frame-Options: DENY
Content-Type: application/xml
Transfer-Encoding: chunked
Date: Fri, 04 Oct 2019 07:35:54 GMT

<applications>
  <versions__delta>1</versions__delta>
  <apps__hashcode></apps__hashcode>
</applications>

请求成功。 

 

2、eureka client工程

2.1、eureka client工程pom：

<!--加上文章头部的公共依赖-->

<dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        </dependency>
</dependencies>

<build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
</build>

 

2.2、eureka client工程启动类：

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;

@SpringBootApplication
@EnableDiscoveryClient
public class EurekaClientApplication 

    public static void main(String[] args) 
        SpringApplication.run(EurekaClientApplication.class, args);

 

2.3、eureka client工程配置文件，路径：eureka-client\src\main\resources\

由于eureka server工程开启了http basic认证，eureka client工程也需要添加相应的账号信息来传递，这里我们通过配置文件来指定。

application-security.yml：

server:
  port: 8081

spring:
  application:
    name: client1

eureka:
  client:
    security:
      basic:
        user: admin
        password: Xk38CNHigBP5jK75
    serviceUrl:
      defaultZone: http://$eureka.client.security.basic.user:$eureka.client.security.basic.password@localhost:8761/eureka/

application.yml：

spring:
  profiles:
    active: security

 

执行：curl -i --basic -u admin:Xk38CNHigBP5jK75 http://localhost:8761/eureka/apps

curl -i --basic -u admin:Xk38CNHigBP5jK75 http://localhost:8761/eureka/apps
HTTP/1.1 200
Set-Cookie: JSESSIONID=C7CE372067A44606E9D3DEA6B64AEDCD; Path=/; HttpOnly
X-Content-Type-Options: nosniff
X-XSS-Protection: 1; mode=block
Cache-Control: no-cache, no-store, max-age=0, must-revalidate
Pragma: no-cache
Expires: 0
X-Frame-Options: DENY
Content-Type: application/xml
Transfer-Encoding: chunked
Date: Fri, 04 Oct 2019 07:53:40 GMT

<applications>
  <versions__delta>1</versions__delta>
  <apps__hashcode>UP_1_</apps__hashcode>
  <application>
    <name>CLIENT1</name>
    <instance>
      <instanceId>192.168.50.161:client1:8081</instanceId>

      <ipAddr>192.168.50.161</ipAddr>
      <status>UP</status>
      <overriddenstatus>UNKNOWN</overriddenstatus>
      <port enabled="true">8081</port>
      <securePort enabled="false">443</securePort>
      <countryId>1</countryId>
      <dataCenterInfo class="com.netflix.appinfo.InstanceInfo$DefaultDataCenterInfo">

      </dataCenterInfo>
      <leaseInfo>
        <renewalIntervalInSecs>30</renewalIntervalInSecs>
        <durationInSecs>90</durationInSecs>
        <registrationTimestamp>1570175584067</registrationTimestamp>
        <lastRenewalTimestamp>1570175584067</lastRenewalTimestamp>
        <evictionTimestamp>0</evictionTimestamp>
        <serviceUpTimestamp>1570175584067</serviceUpTimestamp>
      </leaseInfo>
      <metadata>
        <management.port>8081</management.port>
      </metadata>
      <homePageUrl>http://192.168.50.161:8081/</homePageUrl>
      <statusPageUrl>http://192.168.50.161:8081/actuator/info</statusPageUrl>
      <healthCheckUrl>http://192.168.50.161:8081/actuator/health</healthCheckUrl>
      <vipAddress>client1</vipAddress>
      <secureVipAddress>client1</secureVipAddress>
      <isCoordinatingDiscoveryServer>false</isCoordinatingDiscoveryServer>
      <lastUpdatedTimestamp>1570175584067</lastUpdatedTimestamp>
      <lastDirtyTimestamp>1570175583914</lastDirtyTimestamp>
      <actionType>ADDED</actionType>
    </instance>
  </application>
</applications>

可以看到eureka client已经成功注册到server。
