Azure自动化:使用python Runbook解析WEBHOOKDATA [英] Azure Automation: Parse WEBHOOKDATA with a python runbook

问题描述

在azure自动化中，当您为Runbook定义Webhook时，请求的标头将通过 WEBHOOKDATA 输入参数传递给Runbook.对于python工作簿，参数作为第一个参数传递给脚本.

In azure automation, when you define a webhook for a runbook the headers of the request are passed to the runbook via the WEBHOOKDATA input parameter. For python workbooks, the parameter is passed as first argument to the script.

例如，这是一本Runbook:

For example, here is a runbook:

import json
import sys

print(sys.argv)

if len(sys.argv) > 1 :
    test = json.loads(sys.argv[1])
    print(test)

这是输入参数 WEBHOOKDATA

{"WebhookName":"python-Test-Arguments","RequestBody":"","RequestHeader":{"Cache-Control":"no-cache","Connection":"keep-alive","Accept":"*/*","Accept-Encoding":"gzip","Host":"s2events.azure-automation.net","User-Agent":"PostmanRuntime/7.1.1","action":"myaction","Postman-Token":"312ce179-d2d1-4b5d-935c-d801fc0ba114","x-ms-request-id":"e6b3a5e3-17b3-4d2a-a00c-a1be928acca2"}}

输出(基本上是 print(sys.argv))

['C:\\Temp\\yjzgss3j.git\\caf4e30b-0cb1-4c60-9e93-e2315b376634', '{WebhookName:python-Test-Arguments,RequestBody:",RequestHeader:{Cache-Control:no-cache,Connection:keep-alive,Accept:*/*,Accept-Encoding:gzip,Host:s2events.azure-automation.net,User-Agent:PostmanRuntime/7.1.1,action:myaction,Postman-Token:312ce179-d2d1-4b5d-935c-d801fc0ba114,x-ms-request-id:e6b3a5e3-17b3-4d2a-a00c-a1be928acca2}}']

json.loads 失败

Traceback (most recent call last): File "C:\Temp\yjzgss3j.git\caf4e30b-0cb1-4c60-9e93-e2315b376634",
line 7, in <module> test = json.loads(sys.argv[1].strip()) File "C:\Python27\lib\json\__init__.py",
line 339, in loads return _default_decoder.decode(s) File "C:\Python27\lib\json\decoder.py",
line 364, in decode obj, end = self.raw_decode(s, idx=_w(s, 0).end()) File "C:\Python27\lib\json\decoder.py",
line 380, in raw_decode obj, end = self.scan_once(s, idx)ValueError: Expecting property name: line 1 column 2 (char 1)

JSON语法对我来说是正确的.可能与编码或Azure自动化如何将参数传递给Runbook有关.

The JSON syntax looks correct to me. Might be something related to encoding, or how Azure automation pass the parameters to runbook.

推荐答案

实际上，我认为您的问题是格式错误的JSON字符串.请注意，您的字符串没有引号:

actually I think that your problem is a malformed JSON string. Notice that your string does not have quotes:

{WebhookName:python-Test-Arguments}

应该是这样的:

{"WebhookName":"python-Test-Arguments"}

要解决此问题，您需要修复响应字符串.这是一个讨论此类操作的线程.

To solve this you need to fix your response string. This is a thread that talk about this kind of operation.
