使用来自 python 的附加参数运行 shell 脚本并将输出作为 python 变量（API 身份验证）

Question

Could someone help me with the following:

I have this line that I normally run in terminal:

 path/to/mysh/script.sh PROD generate-ticket username

and it gives me the following output in terminal:

{"user":{"Userid":123,"firstName":"Joe","SecondName":"Doe","loginName":"jdoe"},"accessToken":"1235df6543cggf432sa24"}

I need the 'accessToken' value assigned to python variable.

My code:

import subprocess
import json 

username ='jdoe'

def get_Access_Token(username):
    s = json.loads(subprocess.check_output(['path/to/mysh/script.sh', 'PROD', 'generate-ticket', username]))


print (s['accessToken'])

but it gives me the following error when trying to print my variable:

NameError: name 's' is not defined

Thanks in advance!

Answer 1

Return the value from the function.

Ex:

import subprocess
import json 

username ='jdoe'

def get_Access_Token(username):
    return json.loads(subprocess.check_output(['path/to/mysh/script.sh', 'PROD', 'generate-ticket', username]))['accessToken']

print (get_Access_Token(username))
