如何在Python中将变量传递给发布请求[重复]

Question

我创建了一个简单的 python 程序来使用请求模块发送 Post Api 请求

# importing the requests library 
import requests 
import json


headers = {
    'PRIVATE-TOKEN': 'XXXXXXXXXXXXX',
    'Content-Type': 'application/json',
}

data = '{ "ref": "cd-pipeline", "variables": [ {"key": "STAGE", "value": "CD"}, {"key": "DEPLOYMENT_STATUS", "value": "failed"} ] }'

response = requests.post('https://gitlab.kazan.atosworldline.com/api/v4/projects/28427/pipeline', headers=headers, data=data)
print(response)

但是，我希望将下面的字符串替换为使用变量

"value": "failed"

下面的东西

"value": deployment_status

Answer 1

如果你想将json数据传递给你的API，你可以直接使用request.post()函数的json属性和一个字典变量。

例子：

# importing the requests library 
import requests 


headers = {
    'PRIVATE-TOKEN': 'XXXXXXXXXXXXX',
    'Content-Type': 'application/json',
}
deployment_status = "failed"
data = { "ref": "cd-pipeline", "variables": [ {"key": "STAGE", "value": "CD"}, {"key": "DEPLOYMENT_STATUS", "value": deployment_status} ] }

response = requests.post('https://gitlab.kazan.atosworldline.com/api/v4/projects/28427/pipeline', headers=headers, json=data)
print(response)

Answer 2

您可以使用“f-string”将变量的值格式化为数据字符串。

例子

deployment_status = 'status'
data = f'{ "ref": "cd-pipeline", "variables": [ {"key": "STAGE", "value": "CD"}, {"key": "DEPLOYMENT_STATUS", "value": "{deployment_status}"} ] }'

Answer 3

如果你有最新版本的 python，你可以使用 f-strings：

deployment_status = 'failed'
data = f'{ "ref": "cd-pipeline", "variables": [ {"key": "STAGE", "value": "CD"}, {"key": "DEPLOYMENT_STATUS", "value": "{deployment_status}"} ] }'

更新：

好的，结果对于 f 字符串来说嵌套太深了。

最好只使用json：

import json

deployment_status = 'failed'
data = {"ref": "cd-pipeline", "variables": [ {"key": "STAGE", "value": "CD"}, {"key": "DEPLOYMENT_STATUS", "value": deployment_status} ] }

print(json.dumps(data))
