B.1.2. 检索服务器模块信息

YANG模块库可能随时间而改变。 如前一节所述，客户端可以从API资源中检索服务器支持的“ietf-yang-library”模块的修订日期。

在本例中，客户端以JSON格式从服务器中检索模块信息：

  1. GET /restconf/data/ietf-yang-library:modules-state HTTP/1.1
  2. Host: example.com
  3. Accept: application/yang-data+json

服务器可能会如下回应：

  1. HTTP/1.1 200 OK
  2. Date: Thu, 26 Jan 2017 20:56:30 GMT
  3. Server: example-server
  4. Cache-Control: no-cache
  5. Last-Modified: Thu, 26 Jan 2017 14:00:14 GMT
  6. Content-Type: application/yang-data+json
