Scrapy 起名爬虫入门 +实战

 

米西米西滴,吃过上午饭来一篇,话说,上回书说道macaca
测试web(3)
,参数驱动来搞,那么有小伙本又来给雷子来要求,
登录模块能或不能够给自己给重新打包一下呢,
作者说干嘛封装,今后不挺好,于是乎,接着小伙伴说,封装好小编得以用的地点就足以直接调用,作者切磋是啊,于是乎,雷子说这不荒谬,你有须求雷子小编有思路,来来,不要说了,来来,封装的代码显示下,起名叫做login.py

 

from page import page_data 
def login(deriver,username,password):
    deriver.element_by_id(page_data['username']).send_keys(username)
    deriver.element_by_id(page_data['password']).send_keys(password)
    deriver.element_by_id(page_data['login']).click()

 爬虫,其实很已经有提到到那么些点,然则一贯未曾长远,前日来搞爬虫。选拔了,scrapy那几个框架

伙伴们说您给自个儿用用,小编还不会用呢,那么来来,作者给你上上代码

入门教程

from macaca import WebDriver
import time,ddt,BSTestRunner,unittest
from config import die_arp,server_url,login_data
from login import login
@ddt.ddt
class BokeyuanTest(unittest.TestCase):
    def setUp(self):
        self.deriver=WebDriver(die_arp,server_url)
        self.deriver.init()
        self.deriver.get('https://passport.cnblogs.com/user/signin')
    def tearDown(self):
        self.deriver.quit()
    @ddt.data(*login_data)
    def test_login(self,login_data):
        login(self.deriver,login_data['username'],login_data['username'])
        time.sleep(1)
        self.assertTrue(self.deriver.element_by_id(login_data['id']).text,login_data['assert'])
if __name__ == '__main__':
    suite = unittest.TestSuite()
    now = time.strftime('%Y-%m%d', time.localtime(time.time()))
    report_dir = r'%s.html' % now
    suite.addTests(unittest.TestLoader().loadTestsFromTestCase(BokeyuanTest))
    re_open = open(report_dir, 'wb')
    runner = BSTestRunner.BSTestRunner(stream=re_open, title='demo by macaca', description='测试结果')
    runner.run(suite)

实则安装照旧很简单的,大家得以直接pip install scrapy

有没有痛感引用相当的粗略吗,是的
答案是必然的,正是函数的调用,封装,只要有思路了,思路打开了,那么共同照旧难题呢,小难题,不用你回答,基于的消除,一切都好办,

若果报错也得以去下载https://pypi.python.org/pypi/Scrapy

又有同伴说,你给本身运营运维下,小编说那么初步吧

Scrapy-1.4.0-py2.py3-none-any.whl
(md5)进行设置,安装报错,必要去下载提示的库,

起名 1

Twisted安装:

下载http://www.lfd.uci.edu/~gohlke/pythonlibs/#twisted

接下来安装

 

安装PyWin32

从官方网站下载对应版本的安装包即可,链接为:https://sourceforge.net/projects/pywin32/files/pywin32/Build%20221/

下图呈现了Scrapy的大致架构,

起名 2

 

测试甘休了,起名 3

二、组件

1、Scrapy Engine(Scrapy引擎)

Scrapy引擎是用来控制总种类统的数目处理流程,并拓展事务处理的触及。更加多的事无巨细内容能够看上边包车型大巴数额处理流程。

2、Scheduler(调度)

调度程序从Scrapy引擎接受请求并排系列入队列,并在Scrapy引擎发出请求后返还给他们。

3、Downloader(下载器)

下载器的首要职分是抓取网页并将网页内容返还给蜘蛛( Spiders)。

4、Spiders(蜘蛛)

蜘蛛是有Scrapy用户自个儿定义用来分析网页并抓取制定U凯雷德L重临的始末的类,每一种蜘蛛都能处理多少个域名或一组域名。换句话说正是用来定义特定网站的抓取和分析规则。

蜘蛛的成套抓取流程(周期)是如此的:

率先取得第2个UPRADOL的初叶请求,当呼吁再次来到后调取二个回调函数。第一个请求是通过调用start_requests()方法。该方式暗许从start_urls中的Url中变化请求,并进行解析来调用回调函数。

在回调函数中,你能够分析网页响应并回到项目对象和请求对象或双方的迭代。那一个请求也将含有一个回调,然后被Scrapy下载,然后有钦定的回调解和处理理。

在回调函数中,你解析网站的情节,同程使用的是Xpath采纳器(可是你也足以运用BeautifuSoup,
lxml或别的任何你喜爱的先后),并转移解析的多少项。

末尾,从蜘蛛重回的品类一般会进驻到项目管道。

⑤ 、Item Pipeline(项目管道)

花色管道的重中之重权利是承担处理有蜘蛛从网页中抽取的门类,他的主要任务是清楚、验证和存储数据。当页面被蜘蛛解析后,将被发送到项目管道,并由此多少个特定的先后处理多少。每一个连串管道的零件都以有二个简易的办法结合的Python类。他们获取了连串并举办他们的主意,同时他们还索要分明的是是不是必要在类型管道中继续执行下一步或是直接抛弃掉不处理。

品类管道平日执行的经过有:

清洗HTML数据
证实解析到的数量(检查项目是或不是含有供给的字段)
自小编批评是还是不是是重复数据(假使重复就删除)
将分析到的数据存款和储蓄到数据库中

陆 、Downloader middlewares(下载器中间件)

下载中间件是置身Scrapy引擎和下载器之间的钩框架,主若是拍卖Scrapy引擎与下载器之间的伸手及响应。它提供了三个自定义的代码的措施来举办Scrapy的职能。下载中间器是多个拍卖请求和响应的钩框架。他是轻量级的,对Scrapy尽享全局控制的平底的种类。

柒 、Spider middlewares(蜘蛛中间件)

蜘蛛中间件是在乎Scrapy引擎和蜘蛛之间的钩框架,首要工作是处理蜘蛛的响应输入和伸手输出。它提供3个自定义代码的情势来展开Scrapy的意义。蛛中间件是三个挂接到Scrapy的蜘蛛处理体制的框架,你能够插入自定义的代码来拍卖发送给蜘蛛的央浼和重临蜘蛛获取的响应内容和项目。

⑧ 、Scheduler middlewares(调度中间件)

调度中间件是在于Scrapy引擎和调度之间的中间件,紧要工作是处从Scrapy引擎发送到调度的乞请和响应。他提供了二个自定义的代码来展开Scrapy的效益。

咱俩设置后能够去建立1个工程,作者起名叫做baidu

scrapy startproject baidu

目录结构

scrapy.cfg: 项目的配置文件

tutorial/: 该项目的python模块。之后您将在此加入代码。

tutorial/items.py: 项目中的item文件.

tutorial/pipelines.py: 项目中的pipelines文件.

tutorial/settings.py: 项目的设置文件.

tutorial/spiders/: 放置spider代码的目录.

那么开始一个爬虫

我们去分析下这个网站 https://movie.douban.com/top250


我们可以看到,界面所有的都是在ol的标签下,元素的class也是唯一的, 那么我们可以定位到这里,去找到所有的电影的一个集合
xptach是//ol[@class="grid_view"]/li
那么我们来分析下下面的电影

 

 

我们可以看到 我们想要获取的元素是很简单的,都是好获取的元素,
那么我们来顶一下我们要获取的,我们在item.py来定义
    ranking=scrapy.Field() 
    movie_name=scrapy.Field() #电影名称
    score=scrapy.Field()  #分数
    score_num=scrapy.Field()#评分人数
    daoyan=scrapy.Field()#导演,演员
    bieming=scrapy.Field()
    url=scrapy.Field()#url地址
几乎我们可以看到我们想要的元素都可以得到,
那么我们来组织我们的代码

from baidu.items import BaiduItem
from scrapy import Request
import re
class XiaoHuarSpider(scrapy.Spider):
    name = 'douban_movie_top250'
    start_urls=[
         'https://movie.douban.com/top250']

    def parse(self, response):
        item = BaiduItem()
        movies = response.xpath('//ol[@class="grid_view"]/li')
        for movie in movies:
            item['ranking'] = movie.xpath('.//div[@class="pic"]/em/text()').extract()[0]
            item['movie_name'] = movie.xpath('.//div[@class="hd"]/a/span[1]/text()').extract()[0]
            item['score'] = movie.xpath('.//div[@class="star"]/span[@class="rating_num"]/text()').extract()[0]
            item['score_num'] = movie.xpath('.//div[@class="star"]/span/text()').re('(\d+)人评价')[0]
            item['daoyan']=movie.xpath('.//div[@class="bd"]/p/text()').extract()[0]
            item['bieming']=movie.xpath('.//div[@class="bd"]/p[@class="quote"]/span/text()').extract()[0]
            item['url']=movie.xpath('.//div[@class="hd"]/a/@href').extract()[0]
            yield item

 

我们来在命令行来跑下我们的代码

scrapy crawl douban_movie_top250 –logfile=test.log
-o
douban_movie_top250.json
-t
json

起名 4

大家得以看出是尚未获取到多少了,惟有log日志

翻阅资料发现有人说着可能是被禁止了,那么我们来修改修改,伪造下
加个headers吧

class XiaoHuarSpider(scrapy.Spider):
    name = 'douban_movie_top250'
    headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/53.0.2785.143 Safari/537.36',}
    def start_requests(self):
        url = 'https://movie.douban.com/top250'
        yield Request(url, headers=self.headers)
    def parse(self, response):
        item = BaiduItem()
        movies = response.xpath('//ol[@class="grid_view"]/li')
        for movie in movies:
            item['ranking'] = movie.xpath('.//div[@class="pic"]/em/text()').extract()[0]
            item['movie_name'] = movie.xpath('.//div[@class="hd"]/a/span[1]/text()').extract()[0]
            item['score'] = movie.xpath('.//div[@class="star"]/span[@class="rating_num"]/text()').extract()[0]
            item['score_num'] = movie.xpath('.//div[@class="star"]/span/text()').re('(\d+)人评价')[0]
            item['daoyan']=movie.xpath('.//div[@class="bd"]/p/text()').extract()
            item['bieming']=movie.xpath('.//div[@class="bd"]/p[@class="quote"]/span/text()').extract()[0]
            item['url']=movie.xpath('.//div[@class="hd"]/a/@href').extract()[0]
            yield item

那么大家再来运维下我们的代码

看下我们的douba.csv

起名 5

 

在来探望咱们的日志模块:

起名 6

 

 大家的日记也得以平常的打字与印刷了,那么大家来看望,我们的数量如同少很多,唯有首先页的,那么大家去分析下大家的页面

起名 7

 

似乎我们明白了什么
那么,我们来改进下我们的代码。
增加下面代码

next_url=response.xpath('//span[@class="next"]/a/@href').extract()
        if next_url:
            next_url='https://movie.douban.com/top250'+next_url[0]
            yield Request(next_url,headers=self.headers)

 那么大家再来爬取下我们的爬虫

起名 8

唯有看我们明日的数据文件大小,大家是打响的,那么大家来看下大家内部的始末

起名 9

 

日记文件展现了成都百货上千事先从未爬取到的小说

起名 10

 

爬虫其实也未尝那么复杂,只要你在半路百折不挠了。

写完正是如此能够run了,思路很简短,正是拆分,组合,包的调用,基础的难题

run下一看看,

起名 15

 

告诉也出来了。

起名 16

 

中间的报错,能够参照上边的消除方案,
因为作者电脑新浪访问今后不平日,笔者要好都登录不了了,只好用事先的浏览器心心念念的密码,好坑爹啊,一会再消除。

急需有没有缓解,好不为难的。

多少驱动,数据与代码完全分开,业务人士只需编写config以及少量简练代码,近来,只有一个报到作用,后续会加盟进去。

有没有觉得更进一步吧。

我们最大的希望正是

注重字驱动,业务逻辑与代码完全分离,业务人士只需编写excel表即可执行ui自动化测试

那几个我们都要相信咱们都得以兑现的
后续都足以解决,通过布置文件去消除那一个题材。

一路向前,你会走的更远。

有无数伙伴不知道自个儿的测报告有啥,感觉很顺眼,其实自身也是用的开源的事物BSTestRunner
援救python3

切切实实代码

起名 17起名 18

"""
A TestRunner for use with the Python unit testing framework. It generates a HTML report to show the result at a glance.

The simplest way to use this is to invoke its main method. E.g.

    import unittest
    import BSTestRunner

    ... define your tests ...

    if __name__ == '__main__':
        BSTestRunner.main()


For more customization options, instantiates a BSTestRunner object.
BSTestRunner is a counterpart to unittest's TextTestRunner. E.g.

    # output to a file
    fp = file('my_report.html', 'wb')
    runner = BSTestRunner.BSTestRunner(
                stream=fp,
                title='My unit test',
                description='This demonstrates the report output by BSTestRunner.'
                )

    # Use an external stylesheet.
    # See the Template_mixin class for more customizable options
    runner.STYLESHEET_TMPL = '<link rel="stylesheet" href="my_stylesheet.css" type="text/css">'

    # run the test
    runner.run(my_test_suite)

再有三个HTMLTestRunner 援助python3

代码如下 

起名 19起名 20

"""
A TestRunner for use with the Python unit testing framework. It
generates a HTML report to show the result at a glance.

The simplest way to use this is to invoke its main method. E.g.

    import unittest
    import HTMLTestRunner

    ... define your tests ...

    if __name__ == '__main__':
        HTMLTestRunner.main()


For more customization options, instantiates a HTMLTestRunner object.
HTMLTestRunner is a counterpart to unittest's TextTestRunner. E.g.

    # output to a file
    fp = file('my_report.html', 'wb')
    runner = HTMLTestRunner.HTMLTestRunner(
                stream=fp,
                title='My unit test',
                description='This demonstrates the report output by HTMLTestRunner.'
                )

    # Use an external stylesheet.
    # See the Template_mixin class for more customizable options
    runner.STYLESHEET_TMPL = '<link rel="stylesheet" href="my_stylesheet.css" type="text/css">'

    # run the test
    runner.run(my_test_suite)
