业务场景介绍

Mockbin 是一个请求响应的测试网站。
我们为KONG添加路由，并将请求转发至Mockbin。

• 单个服务可以有多个路由。
• Kong的配置，包括添加服务和路由，是通过该API的请求进行的，默认http端口为8001。
• Kong默认处理路由转发的请求端口为8000。

使用ADMIN API添加服务

$ curl -i -X POST \
  --url http://localhost:8001/services/ \
  --data 'name=example-service' \
  --data 'url=http://mockbin.org'

应答信息：

Content-Type: application/json; charset=utf-8

{
  "host":"mockbin.org",
  "created_at":1587349286,
  "connect_timeout":60000,
  "id":"7bed6af7-c6d0-4228-a2b0-e0103d17aa0a",
  "protocol":"http",
  "name":"example-service",
  "read_timeout":60000,
  "port":80,
  "path":null,
  "updated_at":1587349286,
  "retries":5,
  "write_timeout":60000,
  "tags":null,
  "client_certificate":null
}

使用ADMIN API添加路由

$ curl -i -X POST \
  --url http://localhost:8001/services/example-service/routes \
  --data 'hosts[]=example.com'

应答信息：

HTTP/1.1 201 Created
Date: Mon, 20 Apr 2020 02:28:52 GMT
Content-Type: application/json; charset=utf-8
Connection: keep-alive

Server: kong/2.0.3
Content-Length: 429
X-Kong-Admin-Latency: 171

{
  "id":"d31de681-7c91-4bb5-8d68-e6bccc10a95f",
  "path_handling":"v0",
  "paths":null,"destinations":null,
  "headers":null,
  "protocols":["http","https"],
  "methods":null,
  "snis":null,
  "service":{"id":"7bed6af7-c6d0-4228-a2b0-e0103d17aa0a"},
  "name":null,
  "strip_path":true,
  "preserve_host":false,
  "regex_priority":0,
  "updated_at":1587349732,
  "sources":null,
  "hosts":["example.com"],
  "https_redirect_status_code":426,
  "tags":null,
  "created_at":1587349732
}

此时，我的第一个路由已经创建成功。

测试KONG路由

使用curl测试Kong的路由转发

$ curl -i -X GET \
  --url http://localhost:8000/ \
  --header 'Host: example.com'

成功响应表示我们的Kong路由配置成功。
