Slash could't save in query?

[JackJun]

i'm writing a rule to watch the log in watcher,i want query regular expression to match the query body,like:

rq:POST /Web/Public/login HTTP/1.1

part of the rule code is

    "query_string": {
      "fields": [
        "rq.keyword"
      ],
      "query": "/POST \/Web\/Public\/login/"
    }

when is click the save button,the Escape character is missing,then,the rule could not be executed.

    "query_string": {
      "fields": [
        "rq.keyword"
      ],
      "query": "/POST /Web/Public/login/"
    }
