【Python+Selenium】百川任务平台自动接取任务脚本

下载链接

1 背景

在该平台上接取任务时，经常由于僧多粥少，无法完成每日工作量，只好趴在电脑前一遍遍刷新，这种机械重复的过程理所应当可以用代码实现。

我没有选择使用连点器，因为连点器需要电脑界面一直停留在浏览器网页上，导致我没法干别的事情，其次，连点器比较死板，对于其他情况没法做出灵活应对。

经查阅资料，Selenium工具可以实现这个功能，于是便有了这篇针对接取百川平台任务的项目。
最后经测试，每个任务语音播放阶段设置为100秒，5秒左右刷新一次网页，大概130秒左右可完成一次视频审改。

2 关键代码

2.1 启动Edge浏览器

options=webdriver.EdgeOptions()  
options.add_experimental_option('detach', True)  
options.add_argument('--user-data-dir=D:\\EdgeData\\')  
#options.add_argument('--headless')  #去掉注释则不显示浏览器界面
driver = webdriver.Edge(options=options)  
driver.get('https://www.baichuanweb.com/bmis/login')  #百川任务平台网址
time.sleep(1)  
#driver.maximize_window() #最大化浏览器界面

2.2 输入账密，点击登录

find_element_error(driver,'//*[@id="app"]/section/div/div/div[1]/form/div[2]/div/div/input').send_keys('15399999999')  
driver.find_element(By.XPATH,'//*[@id="app"]/section/div/div/div[1]/form/div[3]/div/div/input').send_keys('110110110')  
driver.find_element(By.XPATH,'//*[@id="app"]/section/div/div/div[1]/form/div[4]/label/span[1]/span').click()  #寻找同意条款的按钮，并勾上
driver.find_element(By.XPATH,'//*[@id="app"]/section/div/div/div[1]/form/div[5]/div/button').click()  #寻找登录按钮，并点击
time.sleep(2)  #等两秒

2.3 开始循环

4 说明

其实这里面还包含了接取任务之后地一系列操作，例如连播语音、确认提交、翻页等操作，甚至晚上睡觉都可以挂在电脑上，兴许你早上起床的时候发现题已经刷完了，但是没有修改等操作，经本人测试，直接提交的话我130题里无学科错误，150题里有一个学科错误。当然，这有点不负责任~
关于在此框架下之后的进一步开发，可以读取脚本里的解析文本，同时读取原题答案里面的文本或图片（大多是图片形式），然后对图片执行OCR，最后利用模型得到两段文本中的答案信息，通过比对，若一样，则进行下一步比如直接提交，若不一样，则提醒用户进行修改，30min以内用户未作出修改（可能暂时不在），则自动放弃该任务。 可以进一步降低学科错误率。
至于模型怎么得到，我也没有，但是同学你可以自己找数据集或者自己标注数据集然后训练呀~
或者我想可能他们也是在默默收集兼职人员对脚本的更改内容，训练模型，待技术成熟，该任务就不存在了。或许老师是假，数据标注师才是真~

demo

5 等等，你不知道怎么使用？你不是很熟悉Python？

来了来了哈，我对代码进行了一些修改，同时打包成了一个Windows可执行文件，更符合非专业宝宝体制。

import os
file_path = "./config.txt"
if not os.path.exists(file_path):
    print("未检测到配置文件config.txt")
    print("正在初始化……")
    file=open(file_path, "w",encoding='utf-8')
    id=input("您的帐号：")
    file.write("您的帐号："+id+"\n")
    pwd=input("您的密码：")
    file.write("您的密码："+pwd+"\n")
    task=input("任务类型（脚本审改or视频审改）：")
    file.write("任务类型："+task+"\n")
    mode=input("模式（仅接取任务or抢题审题一条龙）：")
    file.write("模式："+mode+"\n")
    file.close()
    print("配置完毕！")
else:
    print("已检测到配置文件config.txt")
    print("正在读取配置信息……")
    file=open(file_path, "r",encoding='utf-8')
    id=file.readline().split("：")[1].strip()
    print("您的帐号："+id)
    pwd=file.readline().split("：")[1].strip()
    print("您的密码："+pwd)
    task=file.readline().split("：")[1].strip()
    print("任务类型："+task)
    mode=file.readline().split("：")[1].strip()
    print("模式："+mode)
    file.close()
    print("读取完毕！")

为方便使用，我把它打包成了一个百川脚本.exe文件，下载点击即可运行~

6 总结

通过该project我初步学会了网页自动化操作，顺带也更加了解html了，有点收获~
