mocking

描述#

Mock API 插件,绑定该插件后将随机返回指定格式的mock数据,不再转发到后端。

属性#

名称类型必选项默认值有效值描述
delayinteger可选延时返回的时间,单位为秒
response_statusinteger可选200返回的响应 http status code
content_typestring可选application/json返回的响应头的 Content-Type。
response_examplestring可选返回的响应体,与response_schema字段二选一
response_schemaobject可选指定响应的jsonschema对象,未指定response_example字段时生效,具体结构看后文说明
with_mock_headerboolean可选true是否返回响应头:"x-mock-by: APISIX/{version}",默认返回,指定为 false 则不返回

支持的字段类型:string, number, integer, boolean, object, array 基础数据类型(string,number,integer,boolean)可通过配置example属性指定生成的响应值,未配置时随机返回。 以下是一个jsonschema实例:

{    "properties":{        "field0":{            "example":"abcd",            "type":"string"        },        "field1":{            "example":123.12,            "type":"number"        },        "field3":{            "properties":{                "field3_1":{                    "type":"string"                },                "field3_2":{                    "properties":{                        "field3_2_1":{                            "example":true,                            "type":"boolean"                        },                        "field3_2_2":{                            "items":{                                "example":155.55,                                "type":"integer"                            },                            "type":"array"                        }                    },                    "type":"object"                }            },            "type":"object"        },        "field2":{            "items":{                "type":"string"            },            "type":"array"        }    },    "type":"object"}

以下为该jsonschema可能生成的返回对象:

{    "field1": 123.12,    "field3": {        "field3_1": "LCFE0",        "field3_2": {            "field3_2_1": true,            "field3_2_2": [                155,                155            ]        }    },    "field0": "abcd",    "field2": [        "sC"    ]}

如何启用#

这里以route为例(service的使用是同样的方法),在指定的 route 上启用 mocking 插件。

curl http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '{    "methods": ["GET"],    "uri": "/index.html",    "plugins": {        "mocking": {            "delay": 1,            "content_type": "application/json",            "response_status": 200,            "response_schema": {               "properties":{                   "field0":{                       "example":"abcd",                       "type":"string"                   },                   "field1":{                       "example":123.12,                       "type":"number"                   },                   "field3":{                       "properties":{                           "field3_1":{                               "type":"string"                           },                           "field3_2":{                               "properties":{                                   "field3_2_1":{                                       "example":true,                                       "type":"boolean"                                   },                                   "field3_2_2":{                                       "items":{                                           "example":155.55,                                           "type":"integer"                                       },                                       "type":"array"                                   }                               },                               "type":"object"                           }                       },                       "type":"object"                   },                   "field2":{                       "items":{                           "type":"string"                       },                       "type":"array"                   }               },               "type":"object"           }        }    },    "upstream": {        "type": "roundrobin",        "nodes": {            "127.0.0.1:1980": 1        }    }}'

测试插件#

mocking插件配置如下时:

{  "delay":0,  "content_type":"",  "with_mock_header":true,  "response_status":201,  "response_example":"{\"a\":1,\"b\":2}"}

curl访问将返回如下结果:

$ curl http://127.0.0.1:9080/test-mock -iHTTP/1.1 201 CreatedDate: Fri, 14 Jan 2022 11:49:34 GMTContent-Type: application/json;charset=utf8Transfer-Encoding: chunkedConnection: keep-alivex-mock-by: APISIX/2.10.0Server: APISIX/2.10.0
{"a":1,"b":2}

移除插件#

当你想去掉mocking插件的时候,很简单,在插件的配置中把对应的 json 配置删除即可,无须重启服务,即刻生效:

curl http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '{    "methods": ["GET"],    "uri": "/index.html",    "upstream": {        "type": "roundrobin",        "nodes": {            "127.0.0.1:1980": 1        }    }}'

现在就已经移除了mocking插件了。其他插件的开启和移除也是同样的方法。
