2021年10⽉最新使⽤selenium爬取裁判⽂书数据（本⽂仅供技术交流使⽤）
作为⼀个java菜鸡，想了解⼀下python的爬⾍，据说⽂书⽹反爬很厉害，遍去试试
好嘛
我去，啥啊，不讲武德
这个⽹站的特点⾸先符合了政府⽹站响应慢的特点，7百亿的访问量。。。，再加上时时刻刻的⼩机器⼈，正常访问都卡的⼀批
有事度娘，⽹上最新的⼏种⽅案，最多的还是，破解post参数
pageId，ciphertext，__RequestVerificationToken 三个参数
我也试过了，都没⼈说过cookie参数怎么搞，都说登录之后，写死就⾏，反正我是没成功，“⽆权限访问接⼝”
继续换，试过web scraper。我去，啥啊，⽂书⽹超时严重，1分钟不带返回的，scraper还总出问题，最⼤的问题就是只能获取单页的，没啥⽤，果断放弃
正题，来了敲⿊板，我要变了
selenium，模拟⽤户⾏为访问，xpath获取数据，暂时这个是搞得挺顺畅
⽂书⽹有个600条限制，就是说最⼤能查到600，在往后查就需要⾼级查询等条件了。
思路敲⿊板
1、看见⾸页这个，法院地图没
把所有法院搞出来（什么？不会搞，我也不会。。。），应该有什么政府⽹能查到这些法院名称，只提供个思路哈，因为我是针对某个法院做的⾼级搜索，然后再具体到⽉份（这样就能限制到600），（什么？要是超过600怎么办，⼤哥哪个法院⼀个⽉能上传有600多⽂书啊，⽂员不得累死–嗯嗯，我是这么认为滴滴滴滴滴滴滴，托下巴表情）
2、然后就是，程序控制浏览器，⾃动打开⽹址，登录，（登录成功后，有时候会让输⼊验证码，⼿动输⼊就⾏了）
在这之前呢，我⼿动⼤体看了下，13年以前的都没有数据（什么？有的有，⼤拇指，⼤家可以往前搞⼏年），（什么？要知道这个⼲嘛），要填⼊整⽉⾼级搜索丫丫丫丫，就是那个裁判⽇期，法院名称填上哪个法院就⾏了（更具体的搜索，⾃⼰填去）
登录成功后呢跳到主页
循环去吧，打开⾼级搜索，填上内容，点击搜索（等那么⼏⼗秒，这玩意不⼀定啊，1分钟最长了），全选⽂章，点击批量下载，点击下⼀页（等那么⼏⼗秒，这玩意不⼀定啊，1分钟最长了），点击全选⽂章，点击批量下载，点击下⼀页。。。。。最后⼀页下载完了打开⾼级搜索，填上内容，点击搜索（等那么⼏⼗秒，这玩意不⼀定啊，1分钟最长了），全选⽂章，点击批量下载，点击下⼀页（等那么⼏⼗秒，这玩意不⼀定啊，1分钟最长了），点击全选⽂章，点击批量下载，点击下⼀页。。。。。最后⼀页下载完了…（⼝渴）
3、上代码
⾕歌浏览器，驱动
from selenium import webdriver
import time
bro = webdriver.Chrome(executable_path='')
# 打开⽹页
<('v/')
最⼤化窗⼝，为什么还是刷新⼀下呢，哎，这玩意加载不完整啊！后边还有刷新，⼤家试试就知道了
# 最⼤化窗⼝
bro.maximize_window()
time.sleep(2)
# 点击登录按钮
login_tag = bro.find_element_by_xpath('//*[@id="loginLi"]/a')
# 执⾏点击命令
time.sleep(2)
login_tag.click();
time.sleep(2)
# 切换到iframe登录窗⼝
bro.switch_to.frame("contentIframe")
。。。。。。
。。。。。
。。。。
。。。
。。
。
不写了，⼤家下边看代码吧
4、注意，敲⿊板，完整代码，以下链接，嘿嘿嘿，只要 5 C币，⼤家搞⼀下哈什么！没看见链接，哎，公司搞什么安全软件，不让上传⽂件了！！瞬间损失了好⼏万
搞上
from selenium import webdriver
import time
bro = webdriver.Chrome(executable_path='')
# 打开⽹页
<('v/')
# 最⼤化窗⼝
bro.maximize_window()
time.sleep(2)
# 点击登录按钮
login_tag = bro.find_element_by_xpath('//*[@id="loginLi"]/a')
# 执⾏点击命令
time.sleep(2)
login_tag.click();
time.sleep(2)
# 切换到iframe登录窗
bro.switch_to.frame("contentIframe")
selenium怎么使用# 定位⼿机号，密码，登录按钮位置
username_path=bro.find_element_by_xpath('//*[@class="phone-number-input"]')
password_path=bro.find_element_by_xpath('//*[@class="password"]')
login_in=bro.find_element_by_xpath('//*[@id="root"]/div/form/div/div[3]/span')
time.sleep(1)
username_path.send_keys("")
time.sleep(1)
password_path.send_keys("")
