Question

这是JSON文件vip5.json。

{
 "App Name": "test", 
 "Email": "test@test.com", 
 "Employee ID": "abc", 
 "Load Balancing Method": "Ratio", 
 "Network": "CMN", 
 "Pool Member": "pucq", 
 "Pool Monitor": "tcp", 
 "Pool name": "pool", 
 "SSL": "Required", 
 "VIP Name": "vs"
}

这是YAML文件test.yaml。

pool_members:

virtual_server:

  ip_protocol: udp

我想获取这些值并将其添加到我的YAML文件的某些字段中。假设我想从JSON文件中的“负载平衡方法：” 中获取Ratio的值，并将其放在“ lb_method：” 中YAML文件。我怎么做？

我试图读取JOSN文件并遍历该文件。但是我不确定这是否可行。

import json
import requests
import yaml

url = "http://127.0.0.1:5000/vip5.json"
r = requests.get(url)
json_file = json.loads(r.content)

print(json_file)

欢迎使用Python！在这种情况下，如果您有一堆键值数据，则最好将两个文档读为dict对象，以便于比较。这是您所描述的解决方案。

import json
import yaml

# Load files as dicts
with open('vip5.json', 'r') as f:
    j = json.load(f)
with open('test.yaml', 'r') as f:
    y = yaml.load(f)
# Assign JSON "Load Balancing Method" to YAML "lb_method".
y['pool']['lb_method'] = j['Load Balancing Method']
print(y)

您可以对此进行详细说明以构建所需的特定映射。有帮助吗？

从JSON文件获取特定值并将其传递到现有YAML文件中的特定字段
