[英]Passing arguments to python script in Azure Devops
I am trying to pass a system variable to the python script from azure devops.我正在尝试将系统变量从 azure devops 传递给 python 脚本。 This is what I currently have in Yaml file:
这是我目前在 Yaml 文件中的内容:
- script: pytest test/test_pipeline.py
--$(global_variable)
--junitxml=$(Build.StagingDirectory)/test_pipeline-results.xml
displayName: 'Testing Pipeline'
condition: always()
The variable I need in my script is $(global_variable)
.我在脚本中需要的变量是
$(global_variable)
。 The variable contains a value of $(Build.SourcesDirectory)
.该变量包含
$(Build.SourcesDirectory)
的值。 It is the global variable.它是全局变量。 I am getting an error message as
"unrecognised arguments"
when I run the job.当我运行作业时,我收到一条错误消息
"unrecognised arguments"
。
Any help to tackle this will be helpful.解决此问题的任何帮助都会有所帮助。
Thanks!谢谢!

##[section]Finishing: Testing Pipeline`
I tried to write a simple sample for you refer.我试着写了一个简单的例子供你参考。
In your .py
file, please use add_argument
to read in the command line parameter.在您的
.py
文件中,请使用add_argument
读取命令行参数。 In this issue, this command line parameter comes from your task specified.在本期中,此命令行参数来自您指定的任务。
A.py
file: A.py
文件:
import argparse
def parse_argument():
parse = argparse.ArgumentParser(description="ForTest!")
parse.add_argument("-test_data")
parse.add_argument("-build_dir")
And then, in PythonScript@0
task:然后,在
PythonScript@0
任务中:
scriptPath: ‘A.py’
argument: -test_data $(myVariable1) -build_dir $(myVariable2)
myVariable1
and myVariable2
are all my customized variable. myVariable1
和myVariable2
都是我自定义的变量。 You can all use environment variable.您都可以使用环境变量。
Since in python script, add_argument
is used to read in the parameter which from command line.由于在 python 脚本中,
add_argument
用于add_argument
读取参数。 So it can receive the value from Argument
specified.因此它可以从指定的
Argument
接收值。
In addition, for the issue which in your question, I think you'd better delete the content from your script: --my_param="/home/vsts/work/1/s"
and try again.另外,对于您问题中的问题,我认为您最好从脚本中删除内容:--
--my_param="/home/vsts/work/1/s"
然后再试一次。 Because --my_param
could not the valid argument for pytest
.因为
--my_param
不能作为pytest
的有效参数。
Hope can help you.希望能帮到你。
