如何使用python从JSON输出中获得唯一匹配的结果？

Question

我已经用selenium python编写了一个脚本，我正处于一个需要对http://localhost:0000/v1/s3status进行get调用的位置，并且输出将如所附的图片所示。Attached output of get call

datasources= requests.get("http://localhost:0000/v1/s3status")

我正在寻找一个只需要特定值的脚本输出的解决方案，stages:{}，validated:{}，failed:{}

所以python脚本的输出应该是这样的：

Datasources of Staged :{Whatever the result will be inside}
Datasources of Failed :{Whatever the result will be inside} 
Datasouces of Validated :{Whatever the result will be inside}

Answer 1

首先，您需要将请求转换为json

import json
import requests

datasources= requests.get("http://localhost:0000/v1/s3status").json()

print("Staged : {}".format(datasources['staged']))
print("Failed : {}".format(datasources['failed']))
print("Validated : {}".format(datasources['validated']))
