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 body 及 header 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#
| Name | Type | Requirement | Default | Valid | Description |
|---|---|---|---|---|---|
| header_schema | object | 可选 | header 数据的 schema 数据结构 | ||
| body_schema | object | 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 } }}'示例#
枚举（Enums）验证:
{ "body_schema": { "type": "object", "required": ["enum_payload"], "properties": { "enum_payload": { "type": "string", "enum": ["enum_string_1", "enum_string_2"], "default": "enum_string_1" } } }}布尔（Boolean）验证:
{ "body_schema": { "type": "object", "required": ["bool_payload"], "properties": { "bool_payload": { "type": "boolean", "default": true } } }}数字范围（Number or Integer）验证:
{ "body_schema": { "type": "object", "required": ["integer_payload"], "properties": { "integer_payload": { "type": "integer", "minimum": 1, "maximum": 65535 } } }}字符串长度（String）验证:
{ "body_schema": { "type": "object", "required": ["string_payload"], "properties": { "string_payload": { "type": "string", "minLength": 1, "maxLength": 32 } } }}正则表达式（Regex）验证:
{ "body_schema": { "type": "object", "required": ["regex_payload"], "properties": { "regex_payload": { "type": "string", "minLength": 1, "maxLength": 32, "pattern": "[[^[a-zA-Z0-9_]+$]]" } } }}数组（Array）验证:
{ "body_schema": { "type": "object", "required": ["array_payload"], "properties": { "array_payload": { "type": "array", "minItems": 1, "items": { "type": "integer", "minimum": 200, "maximum": 599 }, "uniqueItems": true, "default": [200, 302] } } }}多字段组合（Multiple Fields）验证:
{ "body_schema": { "type": "object", "required": ["boolean_payload", "array_payload", "regex_payload"], "properties": { "boolean_payload": { "type": "boolean" }, "array_payload": { "type": "array", "minItems": 1, "items": { "type": "integer", "minimum": 200, "maximum": 599 }, "uniqueItems": true, "default": [200, 302] }, "regex_payload": { "type": "string", "minLength": 1, "maxLength": 32, "pattern": "[[^[a-zA-Z0-9_]+$]]" } } }}
