我正在尝试下载文件:

> URL <- "https://www.bitmarket.pl/graphs/BTCPLN/90m.json"
> download.file(URL, destfile = "res.json", method = "curl")
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed

但它返回503状态。整体输出:

wget也不起作用: 
--2017-12-09 14:01:29--  https://www.bitmarket.pl/graphs/BTCPLN/90m.json
Resolving www.bitmarket.pl... 104.20.67.184, 104.20.68.184

HTTP request sent, awaiting response... 503 Service Temporarily Unavailable
2017-12-09 14:01:29 ERROR 503: Service Temporarily Unavailable.

但是，当您转到以下链接: https://www.bitmarket.pl/graphs/BTCPLN/90m.json时，您的网络浏览器将返回正确的json文件。任何想法为什么它不起作用？

最佳答案

那是因为页面正在使用DDoS保护服务。在第一次加载时，页面本身会在5秒钟后执行JavaScript启动的重定向，以获取最终内容，因此该过程会因无法解释JavaScript的wget / curl之类的工具而失败。如果您认为这样做是合理的，那么一种选择是使用例如 phantomjs 并提供一个自定义脚本(例如save.js):

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

page.userAgent = 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_6) AppleWebKit/604.3.5 (KHTML, like Gecko) Version/11.0.1 Safari/604.3.5';

page.open(system.args[1], function(){
    setTimeout(function(){
        console.log(page.evaluate(function(){
            //gets the JSON from the first <pre> element rendered on the page
            return document.getElementsByTagName('pre')[0].textContent;
        }));
        phantom.exit();
    }, 6000); //waits 6 seconds for the page to reload
});

然后将其代替 wget用作: 
phantomjs save.js https://www.bitmarket.pl/graphs/BTCPLN/90m.json
