| Action | 是 | String | 公共参数，本接口取值：ListFunctions。 |
| Version | 是 | String | 公共参数，本接口取值：2018-06-08。 |
| Region | 否 | String | 公共参数，本接口不需要传递此参数。 |
| EnvId | 是 | String | 命名空间 示例值：lowcode-5gtny6fc61de9566 |
| Order | 否 | String | 以升序还是降序的方式返回结果，可选值 ASC 和 DESC 示例值：DESC |
| Orderby | 否 | String | 根据哪个字段进行返回结果排序,支持以下字段：AddTime, ModTime, FunctionName 示例值：ModTime |
| Offset | 否 | Integer | 数据偏移量，默认值为 0 示例值：0 |
| Limit | 否 | Integer | 返回数据长度，默认值为 20 示例值：10 |
| SearchKey | 否 | String | 支持FunctionName模糊匹配 示例值：kong555 |
| Description | 否 | String | 函数描述，支持模糊搜索 示例值：kong555 |
| Filters.N | 否 | Array of Filter | 过滤特定属性或者有特定标签的函数。- 传值方式key-value 进行传值 例如："Filters": [{ "Name": "Status", "Values": ["CreateFailed","Creating"]}, {"Name": "Type","Values": ["HTTP"]}]上述条件的函数是，函数状态为创建失败或者创建中，且函数类型为 HTTP 函数如果通过标签进行过滤：- tag:tag-key - String - 是否必填：否 - （过滤条件）按照标签键值对进行过滤。 tag-key使用具体的标签键进行替换。示例值："Filters": [{"Name":"tag-dmtest","Values":["dmtest"]}]入参限制：1.每次请求的Filters的上限为10，Filter.Values的上限为5。2.[VpcId', 'SubnetId', 'ClsTopicId', 'ClsLogsetId', 'Role', 'CfsId', 'CfsMountInsId', 'Eip'] 过滤的Name 为这些属性时， values 只能传一个值3.['Status', 'Runtime', 'Type', 'PublicNetStatus', 'AsyncRunEnable', 'TraceEnable', 'Stamp'] 过滤的Name 为这些属性时 ，values 可以传多个值 |
3. 输出参数
| 参数名称 | 类型 | 描述 |
|---|---|---|
| Functions | Array of Function | 函数列表 注意：此字段可能返回 null，表示取不到有效值。 |
| TotalCount | Integer | 总数 示例值：5 |
| RequestId | String | 唯一请求 ID，由服务端生成，每次请求都会返回（若请求因其他原因未能抵达服务端，则该次请求不会获得 RequestId）。定位问题时需要提供该次请求的 RequestId。 |
