期望的行为

我想在本地测试一个 apiman API 以查看apiman-quickstarts/echo-service的响应(或者如果这在最新版本的 apiman 中不再适用,那么任何 echo 响应都会很棒)。

我试过的

我使用来自官方 apiman 站点apiman的以下内容进行安装: Ubuntu 17.10

mkdir ~/apiman-1.3.1.Final
cd ~/apiman-1.3.1.Final
curl http://download.jboss.org/wildfly/10.1.0.Final/wildfly-10.1.0.Final.zip -o wildfly-10.1.0.Final.zip
curl http://downloads.jboss.org/apiman/1.3.1.Final/apiman-distro-wildfly10-1.3.1.Final-overlay.zip -o apiman-distro-wildfly10-1.3.1.Final-overlay.zip
unzip wildfly-10.1.0.Final.zip
unzip -o apiman-distro-wildfly10-1.3.1.Final-overlay.zip -d wildfly-10.1.0.Final
cd wildfly-10.1.0.Final
./bin/standalone.sh -c standalone-apiman.xml

使用 apiman GUI ( localhost:8080/apimanui/api-manager),我创建了一个Organisation、一个Public API没有API Security、一个Endpoint任意定义为http://localhost:8080/apiman-echo和一个Client App。由于 API 被定义为Public,我的理解是不需要ContractClient App. 该Managed EndpointAPI 在 GUI 中提供为:

https://localhost:8443/apiman-gateway/MyTestOrganisation/MyTestAPI/2.0

实际行为

这些是卷曲结果:

# using the 'managed endpoint' provided in the gui - https
curl -k https://localhost:8443/apiman-gateway/MyTestOrganisation/MyTestAPI/2.0
<html><head><title>Error</title></head><body>404 - Not Found</body></html>

# using the 'managed endpoint' provided in the gui - http
curl -k http://localhost:8443/apiman-gateway/MyTestOrganisation/MyTestAPI/2.0
curl: (52) Empty reply from server

#using the endpoint i defined
curl -k http://localhost:8080/apiman-echo
<html><head><title>Error</title></head><body>404 - Not Found</body></html>

速成课程文档 ( apiman.io/latest/crash-course.html ) 指出以下是 apiman 文件夹的内容,但是在我的电脑上quickstartswildfly-10.1.0.Final文件夹中搜索不会返回任何结果:

├── apiman
│   ├── data
│   │   ├── all-policyDefs.json
│   │   └── apiman-realm.json
│   ├── ddls

│   │   └── README.md
│   └── sample-configs
│       ├── apiman-ds_mysql.xml
│       └── apiman-ds_postgresql.xml

我觉得我在某处遗漏了几个与“安装”echo-service并使其可用于测试的步骤。

echoapiman.gitbooks.io/apiman-user-guideapiman.gitbooks.io/apiman-production-guide中搜索不会产生任何结果,而apiman.io/latest/developer-guide.html状态:

模拟后端 API 是一个简单的“回声”API,它使用 JSON 有效负载响应所有请求,描述它收到的请求

但我不确定如何解释和利用这些信息。

我想我已经找到了解决办法。

此处的博客文章中有一个部分称为“获取、构建和部署示例 API”,其内容似乎与早期版本的 apiman 更相关,但通常是正确的。

我在下面记录我的过程和结果,以防它帮助其他人。

博客文章中的以下步骤导致编译错误:

# make a directory on desktop to clone files into
mkdir ~/Desktop/my_container_for_echo_quickstart

# change into directory
cd my_container_for_echo_quickstart

# git clone
git clone https://github.com/apiman/apiman-quickstarts.git

# change into directory
cd apiman-quickstarts/echo-service/

# install maven so i can run `mvn package` 
sudo apt install maven

# run `mvn package`
mvn package

记录大量下载信息后,显示以下错误:

然后我寻找java版本并得到以下信息:

java -version
openjdk version "1.8.0_151"
OpenJDK Runtime Environment (build 1.8.0_151-8u151-b12-0ubuntu0.17.10.2-b12)
OpenJDK 64-Bit Server VM (build 25.151-b12, mixed mode)

所以我这样做了:

sudo apt-get update
sudo apt-get install openjdk-8-jdk
mvn package

并得到BUILD SUCCESS. 博客文章继续说:

如果您仔细观察,在输出的末尾附近,您会看到 .war 文件的位置

它实际上输出.jar文件的位置:

Building jar: /home/me/Desktop/my_container_for_echo_quickstart/apiman-quickstarts/echo-service/target/apiman-quickstarts-echo-service-1.3.1.Final-javadoc.jar

但是.war在同一目录中有一个文件:

apiman-quickstarts-echo-service-1.3.1.Final.war

所以我将它复制到/home/me/apiman-1.3.1.Final/wildfly-10.1.0.Final/standalone/deployments另一个终端并看到服务器输出发生变化:

20:10:54,463 INFO  [org.jboss.as.repository] (DeploymentScanner-threads - 1) WFLYDR0001: Content added at location /home/me/apiman-1.3.1.Final/wildfly-10.1.0.Final/standalone/data/content/c6/*****/content
20:10:54,482 INFO  [org.jboss.as.server.deployment] (MSC service thread 1-6) WFLYSRV0027: Starting deployment of "apiman-quickstarts-echo-service-1.3.1.Final.war" (runtime-name: "apiman-quickstarts-echo-service-1.3.1.Final.war")

这是产生的卷曲结果:

curl -k http://localhost:8080/apiman-echo
{
  "method" : "GET",
  "resource" : "/apiman-echo",
  "uri" : "/apiman-echo",
  "headers" : {
    "Accept" : "*/*",
    "User-Agent" : "curl/7.55.1",
    "Host" : "localhost:8080"
  },
  "bodyLength" : null,
  "bodySha1" : null
}

虽然这令人鼓舞,但我担心因为我首先在 apiman GUI 中使用端点设置 API,/apiman-echo它与我通过 maven 进程创建的端点之间会发生冲突,但我们会看到。
