request-validation

目录#

名称#

request-validation 插件用于提前验证请求向上游转发请求,可以验证请求的 bodyheader 数据。

该插件使用 Json Schema 进行数据验证,有关 Json Schema 的更多信息,请参阅 JSON schema

属性#

NameTypeRequirementDefaultValidDescription
header_schemaobject可选header 数据的 schema 数据结构
body_schemaobject可选body 数据的 schema 数据结构

如何启用#

创建一条路由并在该路由上启用 request-validation 插件:

curl http://127.0.0.1:9080/apisix/admin/routes/5 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '{    "uri": "/get",    "plugins": {        "request-validation": {            "body_schema": {                "type": "object",                "required": ["required_payload"],                "properties": {                    "required_payload": {"type": "string"},                    "boolean_payload": {"type": "boolean"}                }            }        }    },    "upstream": {        "type": "roundrobin",        "nodes": {            "127.0.0.1:8080": 1        }    }}'

测试插件#

curl --header "Content-Type: application/json" \  --request POST \  --data '{"boolean-payload":true,"required_payload":"hello"}' \  http://127.0.0.1:9080/get

如果 Schema 验证失败,将返回 400 bad request 错误。

禁用插件#

在路由 plugins 配置块中删除 request-validation 配置,即可禁用该插件。

curl http://127.0.0.1:9080/apisix/admin/routes/5 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '{    "uri": "/get",    "plugins": {    },    "upstream": {        "type": "roundrobin",        "nodes": {            "127.0.0.1:8080": 1        }    }}'
