如何将网络架构电缆验证报告转换为 HTML

本文介绍如何将 Nexus 网络架构电缆验证报告从 JSON 输出形式转换为 HTML。

先决条件

• 需要 Python 3.11 或更高版本
• 需要 Python 3.11 模块：json pandas as pd datetime

用于将电缆验证 JSON 转换为 HTML 的 Python 脚本

import json
import pandas as pd
from datetime import datetime

def color_status(val):
    """
    Takes a scalar and returns a string with
    the css property `'color: green'` for compliant,
    `'color: red'` for noncompliant and black for others
    """
    if val == 'Compliant':
        color = 'green'
    elif val == 'NonCompliant':
        color = 'red'
    else:
        color = 'black'
    return 'color: %s' % color

now = datetime.now() # current date and time
date_time = now.strftime("%m-%d-%Y-%H-%M")
print("date and time:",date_time)

# Get the file name as input from the user
file_name = input("Please provide post validation json file: ")
# Load the JSON data from the file
with open(file_name, 'r') as f:
    data = json.load(f)

# Write the string to an HTML file
with open('CableValidationAndSpecification-{filename}.html'.format(filename = date_time), 'w') as f:
    f.write(html_string)

使用情况

要运行转换工具，请执行以下命令：

python cable-html.py
..
Please provide post validation json file: <CABLE_VALIDATION_FILENAME>.json

输出的报告具有文件名 CableValidationAndSpecification-<DATE>.html。
