Question

我正在试图抓一个网站：http://www.vehiculo-robado.com但是还是给我这个：

error:       null
statusCode:  200
body:        <html style="height:100%"><head><META NAME="ROBOTS" CONTENT="NOINDEX, NOFOLLOW"><meta name="format-detection" content="telephone=no"><meta name="viewport" content="initial-scale=1.0"><meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1"></head><body style="margin:0px;height:100%"><iframe src="/_Incapsula_Resource?CWUDNSAI=9&xinfo=6-31980899-0%202NNN%20RT%281508782951589%204%29%20q%280%20-1%20-1%20-1%29%20r%280%20-1%29%20B12%284%2c315%2c0%29&incident_id=874000030218433631-157072954141311030&edet=12&cinfo=04000000" frameborder=0 width="100%" height="100%" marginheight="0px" marginwidth="0px">Request unsuccessful. Incapsula incident ID: 874000030218433631-157072954141311030</iframe></body></html>

网络有HTML ......

这是我用来刮网的中间件：

const request = require('request');

function webScraped(req,res,next){      
    const url = `http://www.vehiculo-robado.com`
    req.webParsed = function webToScrape (callback){ 
        request(url, function(error, response, body){
            console.log('error:', error);
            console.log('statusCode:', response && response.statusCode);
            console.log('body =========>', body)
            return callback(false, body);
        })
    }
    next()
}

module.exports = webScraped

我尝试过像谷歌这样的其他网站，它让我的回复很好。我不知道我做错了什么。

该网站（vehiculo-robado）正在使用名为SiteLock的抓取保护服务。这就是为什么它拒绝您的请求并向您发送基本为空的html的原因。这是我得到的答复：

<html style="height:100%">

<head>
  <META NAME="ROBOTS" CONTENT="NOINDEX, NOFOLLOW">
  <meta name="format-detection" content="telephone=no">
  <meta name="viewport" content="initial-scale=1.0">
  <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
</head>

<body style="margin:0px;height:100%"><iframe

可以通过将您的请求调整为普通用户的浏览器请求来绕过它。

使用节点npm请求进行网页抓取
