我在jsoup中删除了一个网址(http://nvsos.gov/sosentitysearch/CorpSearch.aspx),但是我可以废弃第一页但无法导航到第二页。
以下是代码段
try
{
string url = "http://nvsos.gov/sosentitysearch/CorpSearch.aspx";
Connection.Response response = Jsoup.connect(url).method(Connection.Method.GET).execute();
Document responseDocument = response.parse();
Element eventValidation = responseDocument.select("input[name=__EVENTVALIDATION]").first();
Element viewState = responseDocument.select("input[name=__VIEWSTATE]").first();
//javascript:__doPostBack('ctl00$MainContent$objSearchGrid$dgCorpSearchResults$ctl54$ctl01','')
response = Jsoup.connect(url)
.data("__VIEWSTATE", viewState.attr("value"))
.data("__EVENTVALIDATION", eventValidation.attr("value"))
.data("ctl00$MainContent$txtSearchBox", "apple") // <- search
.data("ctl00$MainContent$btnCorpSearch", "Search")
.data("ctl00$MainContent$ddlCorpSortColumns", "m")
.data("ctl00$MainContent$ddlCorpNumSortColumns", "m")
.data("ctl00$MainContent$ddlOfficerSortColumns", "m")
.data("ctl00$MainContent$ddlRASortColumns", "m")
.data("ctl00$MainContent$ddlABNSortColumns", "m")
.data("ctl00$MainContent$ddlABNSortColumns", "m")
.data("ctl00$MainContent$rdlSortOrder", "d")
.data("ctl00$MainContent$objSearchGrid$dgCorpSearchResults$ctl54$ctl01", "")
.method(Connection.Method.POST)
.followRedirects(true)
.execute();
Document document = response.parse(); //search results
System.out.println(document);
}
catch (IOException e)
{
e.printStackTrace();
}
此处.data("ctl00$MainContent$objSearchGrid$dgCorpSearchResults$ctl54$ctl01", "")
将导航到第二页,但它始终会返回第一页。
答案 0 :(得分:0)
您可能遗漏了一些Cookie。请尝试以下代码:
response = Jsoup.connect(url)
.cookies(response.cookies()) // Add cookies received when fetching the first page
.data("__VIEWSTATE", viewState.attr("value"))
.data("__EVENTVALIDATION", eventValidation.attr("value"))
.data("ctl00$MainContent$txtSearchBox", "apple") // <- search
.data("ctl00$MainContent$btnCorpSearch", "Search")
.data("ctl00$MainContent$ddlCorpSortColumns", "m")
.data("ctl00$MainContent$ddlCorpNumSortColumns", "m")
.data("ctl00$MainContent$ddlOfficerSortColumns", "m")
.data("ctl00$MainContent$ddlRASortColumns", "m")
.data("ctl00$MainContent$ddlABNSortColumns", "m")
.data("ctl00$MainContent$ddlABNSortColumns", "m")
.data("ctl00$MainContent$rdlSortOrder", "d")
.data("ctl00$MainContent$objSearchGrid$dgCorpSearchResults$ctl54$ctl01", "")
.method(Connection.Method.POST)
.followRedirects(true)
.execute();
