# 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 ## 下载脚本
```
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` git clone https://github.com/ds19991999/csdn-spider.git
cd csdn-spider
```shell
python3
python3 -m pip install -r requirements.txt 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 if __name__ == "__main__":
git clone https://github.com/ds19991999/csdn-spider.git import CSDN
CSDN.run("ds19991999")
``` ```
## 三、用法 ## LICENSE
### 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**
![1571483777703](assets/1571483777703.png)
## 五、LICENSE
