从《部落冲突》API 下载玩家数据-Python教程-PHP中文网

Downloading Player Data from Clash of Clans API

您是《部落冲突》爱好者，同时也热衷于数据分析或应用程序开发吗？在这篇文章中，我将引导您完成使用 Python 从《部落冲突》API 下载玩家数据的过程。这对于部落管理工具、玩家统计分析，甚至构建您自己的《部落冲突》相关应用程序非常有用。

先决条件

在我们深入之前，请确保您已经：

您的机器上安装了Python
Python编程基础知识
《部落冲突》开发者帐户（我们将介绍如何获取此帐户）

第 1 步：设置您的开发者帐户

首先，您需要注册一个《部落冲突》开发者帐户：

前往《部落冲突》API 开发者网站
创建帐户并登录
生成 API 密钥 - 您需要它来访问数据

第 2 步：安装所需的库

我们将在此项目中使用多个 Python 库。使用 pip 安装它们：

pip install requests pandas tqdm ratelimit

登录后复制

第三步：代码

让我们将代码分解为可管理的块：

导入库并设置

import time
import math
import json
import requests
import logging
import pandas as pd
from concurrent.futures import ThreadPoolExecutor, as_completed
from ratelimit import limits, sleep_and_retry
from tqdm import tqdm

def extract_tags_from_file(file_path):

        data = json.load(file)
        return [item.get("tag") for item in data.get("items", [])]

# Extract tags from the specified file
try:
    extracted_tags = extract_tags_from_file(file_path)
    print(extracted_tags)
