Tutorial 2 动态mock服务能力

有时候静态配置无法满足我们的需求, 因此我们要做出动态的决定, 甚至, 有时候还需要有 持久化能力

通过简单配置 URL配置 和 python文件, 就可以实现 强大的 动态mock能力

这里以 https://github.com/knightliao/pfrock-demos/tree/master/demos/http-demo 为demo

hello world

配置文件

{
    "servers": [
        {
            "port": 8888,
            "routes": [
                {
                    "path": "/api",
                    "methods": [
                        "GET"
                    ],
                    "handler": "pfrock_http_plugin",
                    "options": {
                        "handler": "mocks.handler.hello_world.HelloWorldHandler"
                    }
                }
            ]
        }
    ]
}

这里将 127.0.0.1:8888/api 路由到 mocks.handler.hello_world.HelloWorldHandler 这个处理方法上

这里method指定只服务于 GET 请求.

记得将 handler 指定为 pfrock_http_plugin

python handler

from pfrock.core.web import PfrockRequestDispatcher

class HelloWorldHandler(PfrockRequestDispatcher):
    def get(self):
        self.write("Hello, world")

实践:

➜  tmp  curl -v '127.0.0.1:8888/api'
*   Trying 127.0.0.1...
* Connected to 127.0.0.1 (127.0.0.1) port 8888 (#0)
> GET /api HTTP/1.1
> Host: 127.0.0.1:8888
> User-Agent: curl/7.43.0
> Accept: */*
>

配置用法

{
    "servers": [
        {
            "port": 8888,
            "routes": [
                {
                    "path": "/api/persistence",
                    "methods": [
                        "GET"
                    ],
                    "handler": "pfrock_http_plugin",
                    "options": {
                        "handler": "mocks.handler.persistence.PersistenceHandler"
                    }
                }
            ]
        }
    ]
}

python handler

from pfrock.core.web import PfrockRequestDispatcher

grower_index = 0


class PersistenceHandler(PfrockRequestDispatcher):
    def get(self):
        global grower_index
        grower_index += 1
        self.write("Hello, world " + str(grower_index))

实践:

第一次

➜  tmp  curl -v '127.0.0.1:8888/api/persistence'
*   Trying 127.0.0.1...
* Connected to 127.0.0.1 (127.0.0.1) port 8888 (#0)
> GET /api/persistence HTTP/1.1
> Host: 127.0.0.1:8888
> User-Agent: curl/7.43.0
> Accept: */*

Hello, world 1%

第二次:

➜  tmp  curl -v '127.0.0.1:8888/api/persistence'

Hello, world 2%

可以看到 grower_index 的值 +1 了
