# 查询账户下所有知识库信息接口文档
## 一、接口概述
`/knowledge/collection/list`接口用于查询某个账户下的所有知识库信息，默认按照知识库的创建时间从晚到早排序。
## 二、前提条件
完成“签名鉴权方式”页面的注册账号、实名认证、AK/SK密钥获取和签名获取后，方可调用该API接口实现查看知识库列表的功能。
## 三、请求接口
|参数|详情|描述|
|---|---|---|
|URI|`/api/knowledge/collection/list`|统一资源标识符|
|请求方法|POST|客户端对向量数据库服务器请求的操作类型|
|请求头|`Content-Type: application/json`
`Authorization: HMAC-SHA256 ***`|请求消息类型
鉴权|
## 四、请求参数
|参数|类型|是否必选|默认值|参数说明|
|---|---|---|---|---|
|project|string|否|--|知识库所属项目，在【访问控制】-【资源管理】-【项目】中创建。若不传，则返回所有project下的知识库|
|brief|bool|否|false|是否查询和返回索引状态，false代表查询和返回索引状态，true代表不查询和返回索引状态|
## 五、响应消息
|参数|参数说明|
|---|---|
|code|状态码|
|message|返回信息|
|request_id|标识每个请求的唯一标识符|
|data|包含total_num（列表里的知识库总数）、collection_list（知识库详细信息列表，数组型，每个元素是一个知识库的详细信息，具体参数形式见info）|
## 六、状态码说明
|状态码|http状态码|返回信息|状态码说明|
|---|---|---|---|
|0|200|success|成功|
|1000001|401|unauthorized|鉴权失败|
