-# CSDN 爬虫脚本
+# CSDN 爬虫
 
-主要功能：爬取 `csdn` 博客指定用户的所有博文并转换为 `markdown` 格式保存到本地。
+> 主要功能：爬取 csdn 博客指定用户的所有博文并转换为 markdown 格式保存到本地。
 
-## 一、运行环境
-
-需要安装`WebDriver`驱动，https://chromedriver.chromium.org/downloads ，下载与本地对应的`chrome`驱动后，将其添加至环境变量`$PATH`
-
-```shell
-python3
+## 下载脚本
+```
+git clone https://github.com/ds19991999/csdn-spider.git
+cd csdn-spider
 python3 -m pip install -r requirements.txt
 ```
 
-## 二、获取脚本
+## 爬取用户全部博文
+```python
+#!/usr/bin/env python
+# coding: utf-8
 
-```shell
-git clone https://github.com/ds19991999/csdn-spider.git
+if __name__ == "__main__":
+    import CSDN
+    CSDN.run("ds19991999")
 ```
 
-## 三、用法
-
-### 1.获取cookie
-
-登录 `csdn` 账号，进入：https://blog.csdn.net ，按 `F12` 调试网页，复制所有的 `Request Headers`，保存到`cookie.txt`文件中
-
-![1571482112632](assets/1571482112632.png)
-
-### 2.添加需要爬取的 `csdn` 用户
-
-在`username.txt`中添加用户名，一行一个
-
-### 3.运行脚本
-
-```shell
-python3 csdn.py
-```
-
-## 四、效果
-
-**运行过程**
-
-![1571483423256](assets/1571483423256.png)
-
-**文章列表建立**：`./articles/username/README.md`
-
-![1571483552438](assets/1571483552438.png)
-
-**爬取的博文**：`./articles/username/`
-
-![1571483479356](assets/1571483479356.png)
-
-**博文转换效果**：
