java - 线程中的异常 "main"java.net.SocketTimeoutException : Read timed out in jsoup

Question

我可以联系this link手动并使用 Firefox 浏览器正确搜索，但我无法使用 JSOUP 连接。

代码:

String url = "https://www.sosnc.gov/trademrk/search.aspx";
Connection.Response response = Jsoup.connect(url).timeout(45000)
            .method(Connection.Method.GET)
            .ignoreContentType(true)
            .userAgent("Mozilla/5.0 (Windows NT 6.3; rv:40.0) Gecko/20100101 Firefox/40.0")  
            .followRedirects(true)
            .execute();
Map<String, String> loginCookies = response.cookies();
Document document = response.parse(); //search results
Element __VIEWSTATE = document.select("input[name=__VIEWSTATE]").first();
Element __VIEWSTATEGENERATOR = document.select("input[name=__VIEWSTATEGENERATOR]").first();
Element __PREVIOUSPAGE = document.select("input[name=__PREVIOUSPAGE]").first();
Element __EVENTVALIDATION = document.select("input[name=__EVENTVALIDATION]").first();
response = Jsoup.connect(url).timeout(45000)
            .data("SosMenu_SiteTreeView_ExpandState", "ennnnnnnnnnnn")
            .data("SosMenu_SiteTreeView_PopulateLog", "")
            .data("SosMenu_SiteTreeView_SelectedNode", "SosMenu_SiteTreeViewn2")
            .data("ToolsTreeView_ExpandState", "ennn")
            .data("ToolsTreeView_PopulateLog", "")
            .data("ToolsTreeView_SelectedNode", "")
            .data("__EVENTARGUMENT", "")
            .data("__EVENTTARGET", "")
            .data("__EVENTVALIDATION", __EVENTVALIDATION.val())
            .data("__PREVIOUSPAGE", __PREVIOUSPAGE.val())
            .data("__VIEWSTATE", __VIEWSTATE.val())
            .data("__VIEWSTATEGENERATOR", __VIEWSTATEGENERATOR.val())
            .data("ctl00$ctl00$SosContent$SosContent$Submit1", "Search")
            .data("ctl00$ctl00$SosContent$SosContent$Type", "Goods")
            .data("ctl00$ctl00$SosContent$SosContent$txtSearc", query)
            .cookies(loginCookies)
            .method(Connection.Method.POST)
            .ignoreContentType(true)
            .userAgent("Mozilla/5.0 (Windows NT 6.3; rv:40.0) Gecko/20100101 Firefox/40.0")  
            .header("host", "www.sosnc.gov")
            .referrer("https://www.sosnc.gov/trademrk/search.aspx")  
            .followRedirects(true)
            .execute();
    document = response.parse(); //search results
    System.out.println(document);

我错过了什么吗？是一个Jsoup post请求到服务器，所以我也添加了Cookie和所需的参数，但仍然无法得到结果。

我不知道为什么会超时，但您可以通过更简单的方式轻松获取数据 -

String query = "abc";
String url = "https://www.sosnc.gov/trademrk/results.aspx?searchstr=" +
              query +
             "&Type=GOODS";
Connection.Response response = Jsoup.connect(url).timeout(45000)
            .method(Connection.Method.GET)
            .ignoreContentType(true)
            .userAgent("Mozilla/5.0 (Windows NT 6.3; rv:40.0) Gecko/20100101 Firefox/40.0")

            .followRedirects(true)
            .execute();
System.out.println(response.body());

不需要 cookie 或额外参数。
