WSO2 API Manager调研学习总结

桃扇骨 2022-05-30 04:55 202阅读 0赞

近期要做一个SOA服务治理相关的项目，详细调研了下WSO2的API Manager（简称，APIM）。因为在调研过程中发现，国内研究WSO2的开发者较少，社区中也不是很活跃，可供直接上手的中文文档很少，好在官网提供的用户文档比较详细，认真研读研读，调研推进起来还不算太费劲，不过源码比较庞大，大致了解下框架。本文梳理下所调研的APIM相关知识，希望能给后来的开发学习者提供一点帮助。

## 一、概述 ##

当企业实现自己的SOA框架时，需要对外以APIs的方式暴露内部系统的一些关键的流程、数据和服务。外部系统可以集成这些开放的APIs构建新的业务的解决方案，这种模式可以以一种去中心化的开发模式快速扩展潜在市场，挖掘潜在客户，带来巨大的经济效益，这就是所谓的“APIs经济”。但以一种协同的方式发挥API的杠杆作用面临着一些挑战：控制管理、可信连接、安全认证等。

WSO2 API Manager是一款可以旨在提供优秀的API管理功能的开源产品，能够实现API的创建、发布、生命周期管理、流量控制、版本控制、治理和安全控制等功能。 已用于WSO2 Enterprise Service Bus、WSO2 Identity Server和WSO2 Governance Registry等产品中。WSO2 API Manager可以为开发团队提供Web页面进行部署、管理和监控API，服务消费者可以进行服务发现、服务订阅以及服务调用。APIM的Key Manager组件默认通信协议是Apache Thrift，另外，APIM可以通过集成WSO2 Analytic平台实现API调用监控及告警。

## 二、安装部署 ##

### 2.1 基本配置 ###

单点部署方式：

![img_59b248d650f0b.png][]

默认Linux环境：Jdk1.8、关闭防火墙，关闭环境中运行Rabbitmq服务，检查端口是否存在冲突  
查看5672端口占用

\# netstat -ntlp|grep 5672

解压安装包：wso2am-2.1.0.zip  
修改配置文件：

vim wso2am-2.1.0/repository/conf/carbon.xml

取消注释，并将主机名换成本机IP即可  
<HostName>192.168.100.87</HostName>  
<MgtHostName>192.168.100.87</MgtHostName>  
保存退出  
启动：  
wso2am-2.1.0/bin/wso2server.sh  
日志打印到标准输出

相关命令：  
–start: Start Carbon using nohup in the background  
–stop: Stop the Carbon server process  
–restart: Restart the Carbon server process

### 2.2 替换后台数据库 ###

参考：[https://docs.wso2.com/display/AM210/Changing+the+Default+API-M+Databases][https_docs.wso2.com_display_AM210_Changing_the_Default_API-M_Databases]

替换默认的后端存储H2为我们熟悉的MySQL数据库。

依次创建以上数据库，例如，

导入数据库表,数据库脚本位于安装目录的/dbscripts目录下:

查看各个数据库中已经存在了数据表。

修改API Manager的数据库，指定以上四个数据库

注意：数据库中中文乱码的主要原因是库、表及字段的编码都是默认的latin1，需要全部设置为UTF-8才可以。

### 2.3 集成APIM Analytics ###

单点上集成Analytics的部署方式：

![img_59b2490b3ab68.png][]

参考：[https://docs.wso2.com/display/AM210/Configuring+APIM+Analytics][https_docs.wso2.com_display_AM210_Configuring_APIM_Analytics]

修改wso2am-2.1.0/repository/conf/api-manager.xml，打开Analytics配置项

关闭wso2server，修改数据源配置WSO2AM\_STATS\_DB，上面已经制定Mysql数据源(这里进行省略)

修改log4j日志配置wso2am-2.1.0/repository/conf/log4j.properties，增加DAS\_AGENT配置，如下

下载并解压wso2am-analytics-2.1.0.zip

修改配置文件：

取消注释，并将主机名换成本机IP即可

修改数据源配置文件wso2am-analytics-2.1.0/repository/conf/datasources/master-datasources.xml，与wso2am-2.1.0/repository/conf/datasources/master-datasources.xml

的WSO2\_CARBON\_DB配置一致

修改数据源配置文件wso2am-analytics-2.1.0/repository/conf/datasources/stats-datasources.xml，与wso2am-2.1.0/repository/conf/datasources/master-datasources.xml

的WSO2AM\_STATS\_DB配置一致

拷贝一份mysql-connector-java-5.1.42-bin.jar至wso2am-analytics-2.1.0/repository/components/lib中

启动wso2am-analytics-2.1.0/bin/wso2server.sh，查看有无错误输出

如果没有，可以浏览器访问：

[https://192.168.100.87:9444/carbon/][https_192.168.100.87_9444_carbon] admin:admin

启动wso2am-2.1.0/bin/wso2server.sh，查看有无错误输出

如果没有，浏览器访问：[https://192.168.100.87:9443/publisher/][https_192.168.100.87_9443_publisher 1]

发现之前的Analytics“Not Configured”已经消失，统计分析页面正常显示。![img_59b2332e4d112.png][]

## 三、APIM介绍 ##

### 3.1 系统架构 ###

![img_59b2339f2558d.png][]

### 3.2 API Gateway ###

加密、保护、管理和度量API的调用。提供了一个简单的API代理，拦截API请求，并应用限流和安全检测的等功能。它同样作为API使用统计的工具。通过https://<Server Host>:9443/carbon访问。

![img_59b2587b26473.png][]

### 3.3 API Publisher ###

具备API信息注册与发布，共享文档，提供API密钥，收集特性、质量和使用的反馈。通过https://<Server Host>:9443/publisher访问。

![img_59b257055406a.png][]

### 3.4 API Store ###

API的消费者，应用系统注册、服务发现和订阅API、评估，并与API Publish进行交互，通过https://<Server Host>:9443/store访问。

![img_59b2577cd5e7a.png][]

### 3.5 API Manager Analytics ###

提供统计图表，针对预设的事件和日志分析具备告警机制。

信息页面嵌入到Publisher和Store系统中，分别如下图所示。

![img_59b2581c5bdc2.png][]

![img_59b257b389c74.png][]

### 3.6 其他组件 ###

Key Manager：处理所有安全和密钥相关的操作，API Gateway连接Key Manager验证订阅  
Traffic Manager: 帮助用户调节API流量，使API和应用以不同的服务级别和安全级别被用户获取。Traffic Manager具备动态限流引擎来实时处理限流策略。

### 3.7 相关概念 ###

（1）用户和角色

创建者：技术角色，理解API的技术层面（接口、文档、版本、如何暴露给网关），使用API publisher发布API给API Store，创建者根据用户反馈使用API Store对API进行评级。创建者可以添加API Store但不能管理他们的声明周期（例如，使他们对外部可见）。  
发布者：管理企业或商业的API，控制API的声明周期  
消费者：消费者使用API Store发现API，查看文档和论坛，评级和评论API，订阅API并获取API密钥。

（2）API生命周期

被创建：注册到系统中  
PROTOTYPED：模拟实现，用户可以不订阅而试用  
被发布：API在API Store中可见并且可以订阅  
DEPRECATED：API仍被部署在API网关中，但对订阅者不可见了，发布新版本API时自动废弃。  
RETIRED：在API网关中不再被发布并从API Store中删除  
BLOCKED：API临时不可用，实时调用被停用，API不在API Store中显示。

（3）应用

应用主要用于将API与消费者解耦，允许：

*  为多个API创建并使用一个简单密钥
 *  以不同的SLA级别多次订阅单一API

（4）流量限制层

与一个API订阅时间相关，可以定义在API层、资源层、订阅层和应用层。它定义了API网关的流量限制次数，例如10TPS（每秒交易数）。可以编辑<API-M\_HOME>/repository/conf/api-manager.xml的<TierManagement>进行禁用。

（5）API密钥

支持两个场景的认证：

*  访问令牌用于识别和认证一整个应用
 *  识别隶属最终用户的应用程序

API密钥是一个简单的字符串，通过HTTP header传输（例如”Authorization: Bearer NtBQkXoKElu0H1a1fQ0DWfo6IX4a,”）在SOAP和REST调用中同样起作用。  
OAuth2用作API密钥管理。

在应用级别上，Application访问令牌对所有的API都有效。这些Token具备确定的过期时间。默认60分钟，可以设置更长时间（修改<API-M\_HOME>/repository/conf/identity.xml的<ApplicationAccessTokenDefaultValidityPeriod>，如果设置负值，意味着永远有效），甚至几周。消费者可以通过API Store直接重新生成token。

在应用用户级别上，可以按需生成访问令牌，为避免令牌过期，可以使用Token API进行更新。同样应用用户访问令牌也有确切的过期时间。默认60分钟，编辑<API-M\_HOME>/repository/conf/identity/identity.xml中的<AccessTokenDefaultValidityPeriod>可以进行设置。

（6）API资源

API由一个或多个资源组成，每个资源处理一中特殊的请求，类似与一个大的API中方法。API资源接受以下可选属性：

*  动作verbs：GET, POST, PUT, DELETE, PATCH, HEAD和OPTIONS
 *  uri-template：定义参考http://tools.ietf.org/html/rfc6570
 *  url-mapping：作为每个servlet规范，扩展映射、路径映射、精准映射
 *  Throttling tiers：一段时间内请求资源次数限制
 *  Auth-Type：None、Application和Application User。

## 四、使用说明 ##

### 4.1 用户及权限管理 ###

在API GateWay中，进行用户创建、修改、删除，以及权限角色的相关管理，如下：

![img_59b259d345e0a.png][]

![img_59b25a223e1ea.png][]

### 4.2 发布API ###

在API Publisher中进行API的设计、实现及管理，这里采用用户文档中所给的一个示例，外部Web Service服务可以提供查询指定电话号码的验证的服务。

首先进行发布API的设计，设计时需要设置名称、HTTP动作及其参数、Url-mapping、可见性等信息，如下：

![img_59b25b9db71b9.png][]

实现阶段，需要设置API所对对应服务提供者的Endpoint，具备生产环境和测试环境的URL信息，如下

![img_59b25c8eb89a9.png][]

管理阶段可以设置是否为默认版本，协议类型，订阅可见性以及流量控制信息，如下：

![img_59b25d01c5e56.png][]

完成配置后，可以选择保存或发布，发布后在设置可见的订阅用户可以在API Store中发现服务，并可以进行订阅调用。

### 4.3 订阅API ###

在API Store中进行应用系统注册、API订阅、调用测试。

首先，注册一个应用系统，名称为Applicaton001，如下：

![img_59b25fcca9059.png][]

然后给应用程序生成用于验证的Key，在后面调用API时需要用到，这里可以指定Key的声明周期，如下：

![img_59b2617053331.png][]

切换到API Tab上，选择需要订阅的PhoneVerification，点击进入，在订阅栏中选择那些应用系统可以订阅，这里选择刚才创建的应用Application001，如下：

![img_59b262478b8b4.png][]

在API Console中测试服务调用，选择应用为已经订阅的Application001，输入一个电话号码，点击尝试调用，如下：

![img_59b263a131627.png][]

正常情况下，调用会有正确返回，如果这里服务URL识别的不对（这里就不对主机识别成了10.10.10.231，这个IP是主机上另外一个网卡所对应的IP，外网可访问的IP应该是192.168.100.87），我们根据它所提供的curl调用测试方法，手动测试下服务是否可用，如下：

正确返回了结果，如下：

![img_59b2659fa3d19.png][]

不难发现，应用系统能够调用API是需要OAuth安全验证，验证方式是通过追加Access\_Token到Http Header的方式进行，也就是说客户端调用，需要通过Http Header指定授权的key才能进行调用。例如，我们在浏览器中直接访问服务，会返回后台需要进行OAuth 认证，请求参数缺少认证所需的Http Header。

![img_59b26711aff74.png][]

这里加上HTTP Header的内容就可以通过验证，得到正确结果。增加Header方式，可以客户端工具指定。例如利用Chrome插件或测试工具中指定，如下：

![img_59b5e0dce86d3.png][]

![img_59b5e15c0f9b3.png][]

Java客户端Demo源码，如下：

请求返回结果：

![img_59b5e225a5db9.png][]

### 4.4 其他一些应用场景 ###

*  改变API请求默认的调解器（Mediation Flow ）：[https://docs.wso2.com/display/AM210/Change+the+Default+Mediation+Flow+of+API+Requests][https_docs.wso2.com_display_AM210_Change_the_Default_Mediation_Flow_of_API_Requests]
 *  协议之间的转换：[https://docs.wso2.com/display/AM210/Convert+a+JSON+Message+to+SOAP+and+SOAP+to+JSON][https_docs.wso2.com_display_AM210_Convert_a_JSON_Message_to_SOAP_and_SOAP_to_JSON]
 *  多租户配置：[https://docs.wso2.com/display/AM210/Managing+Tenants][https_docs.wso2.com_display_AM210_Managing_Tenants]
 *  工作流扩展： [https://docs.wso2.com/display/AM210/Managing+Workflow+Extensions][https_docs.wso2.com_display_AM210_Managing_Workflow_Extensions]
 *  启用监控通知：[https://docs.wso2.com/display/AM210/Managing+Alerts+with+Real-time+Analytics][https_docs.wso2.com_display_AM210_Managing_Alerts_with_Real-time_Analytics]
 *  多样化部署AM集群：[https://docs.wso2.com/display/AM210/Deployment+Patterns][https_docs.wso2.com_display_AM210_Deployment_Patterns]

## 五、源码研究 ##

### 5.1 源码编译 ###

下载源码，直接利用Maven进行Build:

注意事项：

*  注意匹配pom.xml中依赖版本，不要直接编译master分支；
 *  最好放可联网的服务器上编译，PC上编译过程较慢；
 *  多次编译（生成依赖组件）、可忽略测试

2.1.0版本所依赖的源码：

### 5.2 源码框架 ###

WSO2产品套件非常全面，API Manager仅仅是产品之一，其他产品像Enterprise Integrator 、Identity  Server、Enterprise Service Bus、Analytics、IoT Server等都非常庞大。所有的产品都基于一个公共的组件就是Carbon Kernel，Carbon Kernel是一个模块化、轻量级、基于OSGi的服务器开发框架，其他的产品都有OSGi插件的形式集成到Carbon Server上，包括这里的Carbon-apimgt和Analytics-apim都开发了服务端的OSGi Bundles集成到Carbon Server中，启动Carbon时自动解析加载、注册装和启动。像在这种庞大的项目中，采用OSGi框架的是明智的，不仅开发出可以重用的组件，而且能够实现强鲁棒性的系统，对于线上运行要求较高的系统，能够做到不停机的增加或禁止某项服务，借助OSGi的组件热插拔属性做到线上服务的动态修补。

![APIM_E6_9E_B6_E6_9E_84-1-1024x713.jpg][]

对于API Manager这样的一个开源组件，我们比较关心的问题是如何二次开发，如何调用后端服务？定制它的前端界面？其实Carbon-apimgt后端会以SOAP和REST的方式提供API管理的Web Service，对于前端，我们比较感兴趣是API Gateway、API Publisher和API Store这三个主要系统的界面如何定制开发，通过查看代码可以发现，Portal开发其实是采用不同的两种方式，API Gateway是在Carbon-apimgt中撰写Jsp代码来完成的（界面感觉有点丑），可以推测其他ESB、Analytics等产品的Gateway后端管理界面和API Gateway都是一样的，而另外一种前端框架是采用WSO2自研所谓的Jaggery全功能框架，我们所熟悉的API Publisher和API Store(界面渲染的比较鲜艳)都是拿它来做的。Jaggery其实是拿JavaScript在前端和后端之间封装了一层服务层，前端可以利用封装好的require()函数，调用后端服务，返回结果传给JS，然后动态转成Html，然后完成页面渲染。

### 5.3 Carbon-Kernel ###

基于OSGi框架，负责Carbon Server(standalone)的启动、配置变量和运行环境的检验、OSGi Bundles的注册及类加载、日志功能等功能，入口主函数程序：org.wso2.carbon.bootstrap.Bootstrap。

OSGi（Open Service Gateway Initiative）该规范和核心部分是一个框架，其中定义了应用程序的生命周期模式和服务注册。基于这个框架定义了大量的OSGi服务：日志、配置管理、偏好，HTTP（运行servlet）、XML分析、设备访问、软件包管理、许可管理、评级、用户管理、IO连接、连线管理、Jini和UPnP。这个框架实现了一个优雅、完整和动态的组件模型。应用程序（称为bundle）无需重新引导可以被远程安装、启动、升级和卸载（其中Java包／类的管理被详细定义）。API中还定义了运行远程下载管理政策的生命周期管理。服务注册允许bundles去检测新服务和取消的服务，然后相应配合。

### 5.4 Carbon-apimgt ###

*  用于构建API Manager产品所依赖的OSGi功能组件、配置文件、静态资源等；
 *  组件功能主要包括Publisher、Store、流量控制、Key Manager、GateWay等功能模块的API、Webservice服务；
 *  生成的组件位于安装目录的wso2am-2.1.0\\repository\\components中。

### 5.5 Analytics-apim ###

与APIM同等部署，修改相同配置，提供监控统计服务。

### 5.6  Jaggery ###

作为减少或消除不同web应用层和API开发不匹配场景，提供一个完全的Javascript方法来编写Web应用程序和服务的所有部分。  
通过允许同时创建应用程序和api从而减少Web应用程序与Web服务之间的差距。

Jaggery应用程序所在目录：  
wso2am-2.1.0/repository/deployment/server/jaggeryapps

Publisher和Store的汉化方案：直接修改Jaggery程序中的本地化文件即可，国际化配置文件为每个Jaggery程序目录下的/site/conf/locales/jaggery/locale\_default.json。

## 六、开发指南 ##

### 6.1 Java Doc ###

[http://product-dist.wso2.com/javadocs/api-manager/2.1.0/][http_product-dist.wso2.com_javadocs_api-manager_2.1.0]

### 6.2 Carbon-kernel DeveloperTools ###

[https://github.com/wso2/carbon-kernel/tree/master/docs/DeveloperTools][https_github.com_wso2_carbon-kernel_tree_master_docs_DeveloperTools]

### 6.3 OSGi Bundles ###

打开OSGi管理控制台：

待系统启动后多次回车进入osgi控制台，

![img_59b250d29965e.png][]

执行ss/install/start/stop等控制命令进行组件的列表查询、安装、启动、停止等操作。这里所依赖的OSGi Bundles共有694个条目。

创建通用osgi-bundle

[https://github.com/wso2/carbon-kernel/blob/master/docs/DeveloperTools/UsingMavenArchetypes.md\#creating-a-generic-osgi-bundle-in-one-step][https_github.com_wso2_carbon-kernel_blob_master_docs_DeveloperTools_UsingMavenArchetypes.md_creating-a-generic-osgi-bundle-in-one-step]

将JARs转为OSGi Bundles

[https://github.com/wso2/carbon-kernel/blob/master/docs/DeveloperTools/ConvertingJARsToOSGiBundles.md][https_github.com_wso2_carbon-kernel_blob_master_docs_DeveloperTools_ConvertingJARsToOSGiBundles.md]

使用OSGi声明服务的注解

[https://github.com/wso2/carbon-kernel/blob/master/docs/DeveloperTools/UsingAnnotationswithOSGiDeclarativeServices.md][https_github.com_wso2_carbon-kernel_blob_master_docs_DeveloperTools_UsingAnnotationswithOSGiDeclarativeServices.md]

### 6.4 Admin Services ###

内部系统所使用SOAP的Web Service，底层有OSGi服务组件提供服务、上层通过UI组件为用户提供服务、通过Service stub来提供WSDL服务。

查看服务列表：

首先打开显示服务的配置项，修改wso2am-2.1.0/repository/conf/carbon.xml，将<HideAdminServiceWSDLs>配置项置为False，然后在osgi管理控制台上输入listAdminServices命令，可以查询到所有的后台SOAP服务，共有119个条目。

![img_59b2534438a5c.png][]

选中需要调用的服务URL，直接在浏览器中添加?wsdl即可获得服务，例如这里我们访问API声明周期的服务https://192.168.100.84:9443/services/LifeCycleManagementService?wsdl，结果如下：

![img_59b2543ce7ee7.png][]

### 6.5 WSO2 APIs ###

提供API管理的相关REST APIs。

[https://docs.wso2.com/display/AM210/apidocs/store/\#guide][https_docs.wso2.com_display_AM210_apidocs_store_guide]

[https://docs.wso2.com/display/AM210/apidocs/publisher/\#guide][https_docs.wso2.com_display_AM210_apidocs_publisher_guide]

## 七、选型考量 ##

考虑到服务集成、服务治理、ESB系统与其他应用的系统耦合度较高，这对需求产品的可靠性、稳定性、可控性等具有较高的要求。API Manager及其他开源产品选型时可进行以下方面的考虑。

如果API Manager现有功能可以满足要求，只想定制前端页面，可以采用以下方案：

*  只改造前端，研究Jaggery框架，修改Publisher和Store页面
 *  调用后台Web Service服务，自行设计业务逻辑，封装开发SDK，利用熟悉前端框架构建Portal

如果API Manager现有的后端服务不能满足需求，需要更深层次的开发，可采用以下方案：

*  借助现有的开发资源，研究底层源码
 *  熟悉OSGi开发框架，开发功能扩展的OSGi模块
 *  必要时写Mail与开发者请教交流

产品上线前的一些测试

*  并发性能测试
 *  稳定性测试
 *  流量控制机制的有效性

API Manager运维的一些考量

*  部署架构的演进：分布式部署、HA部署、LB部署
 *  故障排查的策略
 *  应急处理的策略
