JSOUP错误获取url状态401

Question

org.jsoup.HttpStatusException: HTTP error fetching URL. Status=401, URL= anyurl at org.jsoup.helper.HttpConnection$Response.execute(HttpConnection.java:449) at org.jsoup.helper.HttpConnection$Response.execute(HttpConnection.java:465) at org.jsoup.helper.HttpConnection$Response.execute(HttpConnection.java:424) at org.jsoup.helper.HttpConnection.execute(HttpConnection.java:178) at org.jsoup.helper.HttpConnection.get(HttpConnection.java:167)

我要做的是从需要身份验证的网址重定向。当我在浏览器中打开它时，url工作正常，但在使用Jsoup时不起作用。有谁解决了这个问题？

doc = Jsoup.connect(url)
    .userAgent("Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/36.0.1985.143 Safari/537.36")
    .timeout(0).get();
