如何为curl——data参数动态创建json对象

挑战:

1. 我有一个元组data= ("Demo"，"BRANCH_NAME"，"BRANCH_NAME_BUILD_NUMBER"，"Dummy">
2. 如果我在数据参数中有n个数字字符串，那么如何为n个字符串创建动态json对象
3. 需要帮助，如果在元组4值，然后在提到的json标签数组4对象创建。

如果你的数据在一个结构体中:

data = ("Demo","BRANCH_NAME","BRANCH_NAME_BUILD_NUMBER","Dummy")
# this also work for any number of strings you will have inside, like:
# data = ("Demo","BRANCH_NAME","BRANCH_NAME_BUILD_NUMBER","Dummy","foo","bar","baz")
# data = ("foo")

你可以这样做:

labels = [{"add": i} for i in data]
out_json = {
"update": {
"labels": labels
}
}

# formatted for better readability
>>> labels
[
{'add': 'Demo'}, 
{'add': 'BRANCH_NAME'}, 
{'add': 'BRANCH_NAME_BUILD_NUMBER'}, 
{'add': 'Dummy'}
]
>>> out_json
{
'update': {
'labels': [
{'add': 'Demo'}, 
{'add': 'BRANCH_NAME'}, 
{'add': 'BRANCH_NAME_BUILD_NUMBER'}, 
{'add': 'Dummy'}
]
}
}
