【旅游景点项目日记 | 第二篇】基于Python中的Selenium爬取携程旅游网景点详细数据_爬取携程旅游景点数据代码

Gitee仓库地址：travel-server：景点旅游项目服务端

3.基于Python中的Selenium爬取携程旅游网景点详细数据

3.1前提环境

1. 确保安装python3.x环境
2. 以管理员身份打开cmd，安装selenium、pymysql、datetime，默认安装最新版即可

pip install selenium
pip install pymysql
pip install datetime

3. 确保chrome安装对应版本的驱动（将该驱动放在chrome安装路径下），用于控制chrome浏览器，并将路径添加到环境变量的Path变量中，如图所示！

   #安装chrome驱动教程链接：

3.2思路

1. 搜索指定城市景点，网站通过分页进行展示；
2. 使用selenium每个景点的详细访问路径，并点击该路径获取详细景点信息，再通过正则表达式获取需要的内容；

3. 如下图，景点的详细信息有：景点名称、景点等级（1-5A）、景点地址、开放时间（有两种，我们采用下面的）、联系电话、景点介绍、景点图片等内容

   

3.3代码详讲

3.3.1查询指定城市的所有景点

• 控制打开chrome，并访问指定查询所有景点路径

    def __init__(self):
        options = Options()
        options.add_argument('--headless')
        service = Service()
        self.chrome = Chrome(service=service)
        self.chrome.get(
            'https://huodong.ctrip.com/things-to-do/list?pagetype=city&citytype=dt&keyword=%E6%A2%85%E5%B7%9E&id=523&name=%E6%A2%85%E5%B7%9E&pshowcode=Ticket2&kwdfrom=srch&bookingtransactionid=1711160613361_6064')
        time.sleep(3)
        self.page = 1
        self.headers = {
            'cookie': 'suid=lh/P1+4RKuhAYg684ErS+g==; suid=lh/P1+4RKuhAYg684ErS+g==',
            'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.116 Safari/537.36',
        }

3.3.2获取详细景点的访问路径

• 使用selenium的根据class定位元素方法，找到详细景点的href属性，即为该景点的访问路径
• 并通过page属性控制访问的页数

	#获取景点请求路径
    def get_url(self):
        while True:

            content = self.chrome.find_element(By.CLASS_NAME, "right-content-list").get_attribute('innerHTML')
            cons = re.findall(r'href="(.*?)" title="(.*?)"', content)
            for con in cons:
                self.detail_url = 'https:' + con[0]
                self.title = con[1]
                print(self.detail_url, self.title)
                self.get_detail()
            self.chrome.find_element(By.CLASS_NAME,'u_icon_enArrowforward').click()
            time.sleep(1)

            self.page += 1
            if self.page == 120:
                break

3.3.3获取景点的详细信息

• 景点的详细信息有：景点名称、景点等级（1-5A）、景点地址、开放时间（有两种，我们采用下面的）、联系电话、景点介绍、景点图片等内容
• 通过正则表达式获取，详细代码如下：
• 并每次获取详细信息之后，将信息保存到mysql数据库中

    def get_detail(self):
        detail_con = requests.get(self.detail_url, verify=False, headers=self.headers).text
        # time.sleep(2)
        '''使用正则获取信息'''
        self.title = ''.join(re.findall(r'<div class="title"><h1>(.*?)<', detail_con, re.DOTALL))
        print('景点名称：'+self.title)

        #self.rank = ''.join(re.findall(r'rankText">(.*?)<', detail_con, re.DOTALL))

        self.address = ''.join(re.findall(r'地址</p><p class="baseInfoText">(.*?)<', detail_con, re.DOTALL))
        self.mobile = ''.join(re.findall(r'官方电话</p><p class="baseInfoText">(.*?)<', detail_con, re.DOTALL))
        self.quality_grade= ''.join(re.findall(r'<div class="titleTips"><span>(.*?)<!--', detail_con, re.DOTALL))
        #self.openTime = ''.join(re.findall(r'开放时间</div><div class="moduleContent">(.*?)<', detail_con, re.DOTALL))

        first_three_characters = self.address[:3]
        print('所在省份城市：'+'广东省'+first_three_characters)

        print('详细地址：'+self.address)
        #print('开放时间：'+self.openTime)
        print('电话：'+self.mobile)
        print('等级：'+self.quality_grade)
        if self.quality_grade=='':
            self.quality_grade=0

        '''使用xpath获取信息'''
        ret = etree.HTML(detail_con)
        desc_cons = ret.xpath('//div[@class="detailModule normalModule"]//div[@class="moduleContent"]')
        desc_titles = ret.xpath('//div[@class="detailModule normalModule"]//div[@class="moduleTitle"]')
        desc_list = []
        desc_title_list = []
        for d in desc_cons:
            des = ''.join(d.xpath('.//text()'))
            desc_list.append(des)
        for d in desc_titles:
            des = ''.join(d.xpath('.//text()'))
            desc_title_list.append(des)
        desc_dict = dict(zip(desc_title_list, desc_list))
        #print(desc_dict)

        first_value = list(desc_dict.values())[:2]  # 获取前两个值
        if len(first_value) >= 1:
            introduction = first_value[0]
        else:
            introduction = ''

        if len(first_value) >= 2:
            opening_hours = first_value[1]
        else:
            opening_hours = ''

        print('介绍：'+introduction)
        print('开放时间：'+ opening_hours)

        '''获取图片链接'''
        img_list = []
        imgs = re.findall(r'background-image:url\((.*?)\)', detail_con, re.DOTALL)
        for img in imgs:
            '''匹配到的同一张图片会有两种尺寸，我们只要大图，所以把尺寸为521*391的匹配出来即可'''
            image = re.search(r'521_391', img)
            if image:
                img_list.append(img)
        print(",".join(img_list))

        conn = pymysql.connect(host='localhost', user='root', password='root',
                               database='travel_ams', charset='utf8mb4')

    attraction_id INT PRIMARY KEY AUTO_INCREMENT COMMENT '景点id，自增',
    attraction_name VARCHAR(20) COMMENT '景点名称',
    resource_type_id INT COMMENT '景点资源类型id',
    province_city VARCHAR(20) COMMENT '景点所在省份城市',
    location VARCHAR(1000) COMMENT '详细位置',
    open_hour VARCHAR(1000) COMMENT '开放时间',
    phone VARCHAR(1000) COMMENT '电话',
    introduction VARCHAR(10000) COMMENT '景点介绍',
