第一种：selenium进行操作。
- 使用自带滑动和按键进行拖拽，会被检测到。大部分屏蔽方式加上也是过不去的。
- 使用selenium中driver的execute_script，Js注入操作。（不通过，不过这段代码在浏览器可正常操作）
js1 = "var slider = document.getElementById('nc_1_n1z'),container = slider.parentNode; " \
"var rect = slider.getBoundingClientRect(),x0= rect.x || rect.left,y0= rect.y || rect.top,w = container.getBoundingClientRect().width,x1= x0 + w,y1= y0; " \
"var mousedown = document.createEvent('MouseEvents'); mousedown.initMouseEvent('mousedown', true, true, window, 0, x0, y0, x0, y0, false, false, false, false, 0, null);slider.dispatchEvent(mousedown);" \
"var mousemove = document.createEvent('MouseEvents'); mousemove.initMouseEvent('mousemove', true, true, window, 0, x1, y1, x1, y1, false, false, false, false, 0, null); slider.dispatchEvent(mousemove);"
driver.execute_script(js1)
- Windows可以用win32api 方式进行滑动。（可通过，局限比较大，点击代码自取）
- Pyautogui 可以在mac和windows进行。（服务器就不可用，点击代码自取）
第二种：puppeteer
- 直接使用puppeteer模块进行操作访问和存储，要比selemium几率大一些，但是还是很难通过。百分之10-20的概率。
const puppeteer = require('puppeteer');
const fs = require('fs');
function update(url) {
(async () => {
// const browser = await puppeteer.launch();
const browser = await puppeteer.launch({
headless: true,slowMo: 150,
args:['--window-size=1920,1080'],
executablePath: '/Applications/Google Chrome.app/Contentas/MacOS/Google Chrome'
})// 启动浏览器,传入headless为false可以打开窗口
// //启动新页面
const page = await browser.newPage();
// //设置页面打开时的页面宽度高度
await page.setUserAgent("Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/69.0.3477.0 Safari/537.36");
await page.setExtraHTTPHeaders({
'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9',
'Accept-Language': 'zh-CN,zh;q=0.9',
'Cache-Control': 'max-age=0',
'Connection': 'keep-alive',
'Sec-Fetch-Dest': 'document',
'Sec-Fetch-Mode': 'navigate',
'Sec-Fetch-Site': 'same-origin',
'Sec-Fetch-User': '?1',
'Upgrade-Insecure-Requests': '1',});
//直接删掉webdriver属性
await page.evaluateOnNewDocument(() => {
const newProto = navigator.__proto__;
delete newProto.webdriver;
navigator.__proto__ = newProto;
});
//defineProperty删除webdriver后如何检测
await page.evaluateOnNewDocument(() => {
Object.defineProperty(navigator, 'webdriver', {
get: () => false,
});
});
await page.evaluateOnNewDocument(() => {
get: () => "Linux x86_64"
});
//防止检测，赋值plugins
await page.evaluateOnNewDocument(() => {
Object.defineProperty(navigator, 'plugins', {
get: () => [
{
0: {type: "application/x-google-chrome-pdf", suffixes: "pdf", description: "Portable Document Format", enabledPlugin: Plugin},
description: "Portable Document Format",
filename: "internal-pdf-viewer",

name: "Chrome PDF Plugin"
},
{

1: {type: "application/x-pnacl", suffixes: "", description: "Portable Native Client Executable", enabledPlugin: Plugin},
description: "",
filename: "internal-nacl-plugin",
length: 2,
name: "Native Client"
}
],
});
});
//window.chrome绕开
await page.evaluateOnNewDocument(() => {
window.chrome = {
runtime: {},
loadTimes: function() {},
csi: function() {},
app: {}
};
});
//早期绕开方式
function hasChrome() {
return !navigator.language || !navigator.languages
};
function hasChrome() {
return !! window.chrome
};
await page.goto(url);
await page.waitForTimeout(5000)
await page.evaluate(
// setTimeout(
function() {
var slider = document.getElementById('nc_1_n1z'), container = slider.parentNode;
var rect = slider.getBoundingClientRect(), x0 = rect.x || rect.left, y0 = rect.y || rect.top,
w = container.getBoundingClientRect().width, x1 = x0 + w, y1 = y0;
var mousedown = document.createEvent("MouseEvents");
mousedown.initMouseEvent("mousedown", true, true, window, 0,
x0, y0, x0, y0, false, false, false, false, 0, null);
slider.dispatchEvent(mousedown);
var mousemove = document.createEvent("MouseEvents");
mousemove.initMouseEvent("mousemove", true, true, window, 0,
x1, y1, x1, y1, false, false, false, false, 0, null);
slider.dispatchEvent(mousemove);
// }, 3000)
});
await page.waitForTimeout(5000)
//page.frames() 获取当前页面所有的 iframe，然后根据 iframe 的名字精确获取某个想要的 iframe
const frame = await page.mainFrame();
const bodyHandle = await frame.$('html'); //获取所有的html
//frame.evaluate()在浏览器中执行函数，相当于在控制台中执行函数，返回一个Promise
const html = await frame.evaluate(body=>body.innerHTML,bodyHandle);
await bodyHandle.dispose();
/* fs.wirteFile有三个参数
* 1,第一个参数是要写入的文件路径
* 2,第二个参数是要写入得内容
* 3,第三个参数是可选参数,表示要写入的文件编码格式,一般就不写,默认就行
* 4,第四个参数是个回调函数 只有一个参数error,来判断是否写入成功
*/
browser.close();
fs.writeFile("a.html",html,error=>{
if(error) return console.log("写入文件失败,原因是:"+error.message);
console.log('写入成功');
// process.kill(browser.process().pid);
});
})();
};
