获取数据源连接列表

列出该知识库的连接，最早的在前。将某个连接的 id 作为 connectionId 传给创建数据源，即可添加通过该连接读取内容的数据源。

只有在 Dify 中为该知识库添加过某个提供商的数据源后，列表中才会出现该提供商的连接。要使用新的提供商，先在 Dify 中添加它的第一个数据源。每个知识库的连接相互独立。选择 status 为 active，且 provider_id 和 configuration 与目标提供商及凭据一致的连接。

具体步骤详见添加数据源。

Path parameters

knowledge_base_idstringrequired#

知识库 ID：即知识库 API 访问 对话框中所示服务 API 端点的最后一段（…/knowledge-fs/spaces/<knowledge base ID>），也是地址栏中 /datasets/new/ 之后的那一段。
