## 基本环境配置 ##

*  python 3.6
 *  pycharm
 *  requests
 *  parsel

pip install requests
    pip install parsel

## 一、分析网页 ##

## 爬虫代码 ##

import requests
    import parsel
    url = 'https://movie.douban.com/subject/26357307/reviews'
    
    headers = { 
      'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9',
      'Host': 'movie.douban.com',

    }
    
    response = requests.get(url=url, headers=headers)
    selector = parsel.Selector(response.text)
    data = selector.css('#content .article .review-list .short-content::text').getall()
    for i in data:
      a = i.strip().replace('\n', '').replace(')', '').replace('(', '')
      with open('花木兰影评' + '.txt', mode='a', encoding='utf-8') as f:
          f.write(a)
          f.write('\n')
      print(a)

## 词云代码 ##

import jieba
    import wordcloud
    import imageio
    # 导入imageio库中的imread函数，并用这个函数读取本地图片，作为词云形状图片
    py = imageio.imread(r"G:\python\demo\案例\花木兰豆瓣影评\木兰.png")
    # 读取文件内容
    f = open(r'G:\python\demo\案例\花木兰豆瓣影评\花木兰影评.txt', encoding='utf-8')
    txt = f.read()
    # print(txt)
    # jiabe 分词 分割词汇
    txt_list = jieba.lcut(txt)
    string = ' '.join(txt_list)
    # 词云图设置
    wc = wordcloud.WordCloud(
            width=1000,         # 图片的宽
            height=700,         # 图片的高
            background_color='white',   # 图片背景颜色
            font_path='msyh.ttc',    # 词云字体
            mask=py,     # 所使用的词云图片
            scale=15,
            stopwords={ ' ', '没有', '真的', '还是', '就是', '如果', '花木兰', '木兰', '花木', '不是', '什么', '一个', '这部', '但是', '觉得', '有点', '虽然', '我们'},
            # contour_width=5,
            # contour_color='red' # 轮廓颜色
    )
    # 给词云输入文字
    wc.generate(string)
    # 词云图保存图片地址
    wc.to_file(r'G:\python\demo\案例\花木兰豆瓣影评\花木兰.png')
