本篇代碼提供者: 青燈教育-巳月老師

知識點:

• 動態數據抓包
• requests發送請求
• json數據解析

開發環境:

運行代碼

• python 3.8

輔助敲代碼

• pycharm 2021.2

第三方模塊

• requests

如果安裝python第三方模塊:

1. win + R 輸入 cmd 點擊確定, 輸入安裝命令 pip install 模塊名 (pip install requests) 回車
2. 在pycharm中點擊Terminal(終端) 輸入安裝命令

如何配置pycharm裡面的python解釋器?

1. 選擇file(文件) >>> setting(設置) >>> Project(項目) >>> python interpreter(python解釋器)

2. 點擊齒輪, 選擇add

3. 添加python安裝路徑

pycharm如何安裝插件?

1. 選擇file(文件) >>> setting(設置) >>> Plugins(插件)

2. 點擊 Marketplace 輸入想要安裝的插件名字 比如:翻譯插件 輸入 translation / 漢化插件 輸入 Chinese

3. 選擇相應的插件點擊 install(安裝) 即可

4. 安裝成功之後 是會彈出 重啟pycharm的選項 點擊確定, 重啟即可生效

基本思路流程（通用）

1. 發送請求
2. 獲取數據
3. 解析數據
4. 保存數據

代碼

導入模塊

import requests # 發送請求 訪問網站
