OpenDiffy部署

调整 sbt 源，设置为国内源

 #如果没有这个目录和文件，可以先手工创建
 #cat ~/.sbt/repositories
 [repositories]
	local
	huaweicloud-maven: https://repo.huaweicloud.com/repository/maven/
	maven-central: https://repo1.maven.org/maven2/
	sbt-plugin-repo: https://repo.scala-sbt.org/scalasbt/sbt-plugin-releases, [organization]/[module]/(scala_[scalaVersion]/)(sbt_[sbtVersion]/)[revision]/[type]s/[artifact](-[classifier]).[ext]

编译源码

# 编译时间较长，需耐心等候
# 编辑后的可执行文件在 ： target/scala-2.12
git clone https://github.com/twitter/opendiffy.git
cd opendiffy
./sbt assembly

启动命令

java -jar diffy-server.jar -candidate='localhost:8080' 
                                   -master.primary='localhost:8081' 
                                   -master.secondary='localhost:8082' 
                                   -service.protocol='http' 
                                   -serviceName='My Service' 
                                   -proxy.port=:8880 
                                   -admin.port=:8881 
                                   -http.port=:8888 
                                   -rootUrl='localhost:8888' 
                                   -summary.email="test@test.com.cn" 
                                   -summary.delay="5" 
                                   -allowHttpSideEffects=true

启动命令解释

    candidate='localhost:9200' 　(待上线版本部署地址)
    master.primary='localhost:9000' (已上线版本地址１)
    master.secondary='localhost:9100' (已上线版本地址２)
    service.protocol='http' 　(http协议或https)
    serviceName='My Service' 　(服务名称,无影响)
    proxy.port=:8880 　(diffy代理端口,所以请求都应从这个端口访问)
    admin.port=:8881 ( 通过http://localhost:8881/admin可以查看请求状况)
    http.port=:8888 (查看界面,在这里可以比较差异)
    rootUrl='localhost:8888' (同上)
    responseMode=primary (代理服务器是否返回结果，默认(empty)无返回，可指定primary返回线上版本，secondary(同线上版本，用于噪音消除），candidate（待测试版本）
    excludeHttpHeadersComparison＝false (是否排除header的差异，不同服务器，cookie，nginx版本可能有所差异，设置为true可以忽略这些差异）
    summary.email＝1"test@test.com.cn" (必填，但没有多大意义)
    summary.delay="5"（延迟时间）
    allowHttpSideEffects=true （为了防止测试对数据造成不必要的影响,diffy默认只支持读,即Post及Ｄelete影响数据的等请求不会转发,如果需要支持这样的请求,需要增加参数）

OpenDiffy验证

编写被测服务A

package com.gykj.test.servicedemo.controller;

import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

@RestController
public class Hello {

    @RequestMapping(value = "/getInfo", method = RequestMethod.GET)
    public String GetInformation(){
        String name = "test";
        int age = 30;
        String id = "1234567890";

        return String.format("name: %s; age: %d; id: %s", name, age, id);
    }

    @RequestMapping(value = "/setInfo", method = RequestMethod.POST)
    public String SetInformation(HttpServletRequest request,
                                 HttpServletResponse response,
                                 @RequestBody Object object){
        return request.getMethod() + "
" +
                request.getRequestURI() + "
" +
                request.getContentType() + "
" +
                object.getClass() + "
" +
                object.toString();
    }
}

编写被测服务 B

package com.gykj.test.servicedemo.controller;

import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

@RestController
public class Hello {

    @RequestMapping(value = "/getInfo", method = RequestMethod.GET)
    public String GetInformation(){
        String name = "wangyong";
        int age = 30;
        String id = "001245731";

        return String.format("name: %s; age: %d; id: %s", name, age, id);
    }

    @RequestMapping(value = "/setInfo", method = RequestMethod.POST)
    public String SetInformation(HttpServletRequest request,
                                 HttpServletResponse response,
                                 @RequestBody Object object){
        return request.getMethod() + "
" +
                request.getRequestURI() + "
" +
                request.getContentType();
    }
}

启动服务

java -jar servicedemo.8080.jar        # http 服务占用端口8080
java -jar servicedemo.8081.jar         # http 服务占用端口8081
java -jar servicedemo.8082.jar        # http 服务占用端口8082

启动 OpenDiffy

java -jar diffy-server.jar -candidate='localhost:8080' -master.primary='localhost:8082' -master.secondary='localhost:8081' -service.protocol='http' -serviceName='My Service' -proxy.port=:8880 -admin.port=:8881 -http.port=:8888 -rootUrl='localhost:8888' -summary.email="wangy01@tech.icbc.com.cn" -summary.delay="5" -allowHttpSideEffects=true

发送请求，可以多发送几次

# 此处服务的地址，为 opendiffy 的地址，由其进行转发
curl -H "Content-Type: application/json;charset=UTF-8" -X POST --data '{"begin}' http://localhost:8880/setInfo
