Question

我必须从给定的URL中删除HTML文档。在我的localhost上，Phantom JS脚本正在返回url。但在实时服务器上，我获得了403禁止状态

scraper.js

var system = require('system');
var page = require('webpage').create();

$url = system.args[1];

page.open($url, function(status) {


    if (status == "success") {

        var content = page.content;
        console.log(content);
    }

    phantom.exit();

});

PhantomJS命令：

phantomjs scraper.js http://www.submarino.com.br/produto/126862765/

刮刀在其他页面上工作正常。但域名www.submarino.com.br和www.americanas.com.br不起作用。我知道它与Akamai有关。带错误输出的响应是：

当它正常工作时返回：

我尝试从hurl.it和其他cURL服务转发此网站，他们可以访问该网址。有什么我可以做的吗？这让我发疯了！

Answer 1

很可能是地理或可疑的IP范围限制。我刚刚试图打开网址，也被拒绝了该页面，然后通过美国代理访问它并能够打开它。只需使用美国或巴西代理。

另外，在抓取模仿真实浏览器行为的重要性时，我建议您在脚本中添加useragent和viewport模拟：

page.viewportSize = { width: 1280, height: 800 };
page.settings.userAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/51.0.2704.106 Safari/537.36";

还要确保订阅错误和控制台消息，以了解目标页面中的任何错误和消息。

page.onConsoleMessage = function(msg) {
  console.log('CONSOLE: ' + msg);
};

page.onError = function (msg, trace) 
{
    console.log(msg);
    trace.forEach(function(item) {
        console.log(' ', item.file, ':', item.line);
    })
}

PhantomJS在localhost上返回状态200，但在实时服务器
