盐州。如果变量在标准输出中有一些词

Question

有一个网页，上面有一大段文字。

我想配置状态以在 curl returns 出错时执行特定操作。

如果变量不包含“StatusDescription : OK”

如何设置检查变量中的一段文本

{% set seqstat = salt['cmd.run']('powershell.exe curl http://127.0.0.1:5001 -UseBasicParsing') %}

{% if seqstat is sameas '*StatusDescription : OK*'  %}

module_run:
  cmd.run:
    - name: 'powershell.exe WRITE-HOST have no Error'

{% else %}

module_run1:
  cmd.run:
    - name: 'powershell.exe WRITE-HOST have Error'

{%- endif -%}

Answer 1

I want to configure the state to perform a certain action if curl returns an error.

有一个名为 http which can query a URL and return the status. Using this (instead of curl) we can check for the status code(s) (200, 201, etc.), as well as matching text. Then we can use requisites 的 Salt 状态到运行后续状态，具体取决于 http.query 的 success/failure。

示例：

我已经添加了一个状态码200的检查，如果你不关心状态码，你可以省略- status: 200。

check-application:
  http.query:
  - name: http://127.0.0.1:5001
  - status: 200
  - match: 'StatusDescription : OK'

app-running:
  cmd.run:
  - name: 'powershell.exe WRITE-HOST have no Error'
  - require:
    - http: check-application

app-not-running:
  cmd.run:
  - name: 'powershell.exe WRITE-HOST have Error'
  - onfail:
    - http: check-application
