This is the code snippet , it always returns error page
try {
String url = "http://kepler.sos.ca.gov/";
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();
response = Jsoup.connect(url)
.data("__VIEWSTATE", viewState.attr("value"))
.data("__EVENTVALIDATION", eventValidation.attr("value"))
.data("ctl00_content_placeholder_body_BusinessSearch1_TextBox_NameSearch", "escrow") // <- search
.data("ctl00_content_placeholder_body_BusinessSearch1_RadioButtonList_SearchType", "Corporation Name")
.data("ctl00_content_placeholder_body_BusinessSearch1_Button_Search", "Search")
.method(Connection.Method.POST)
.followRedirects(true)
.execute();
Document document = response.parse(); //search results
System.out.println(document);
} catch (IOException e) {
e.printStackTrace();
}
I got the request response from net panel of firebug and sent the same. Am I missing something?
Depending on your android version, that code will give a "NetworkOnMainThreadExcpetion" if you try to run it directly from a button click or something like that. On honeycomb or later, you have to do network access from a separate explicit thread or a AsyncTask.
From my debugging, you need to add some cookies. That's included below. Also, a couple of your form fields were missing dollar signs, and there were some blank form fields being passed that were empty but the server might expect, so I included those too.
For future reference, I recommend the tool Fiddler to debug issues like this if you're not using it already.
class DownloadFilesTask extends AsyncTask<Void, Integer, Long> {
protected Long doInBackground(Void... params) {
long totalSize = 0;
try {
String url = "http://kepler.sos.ca.gov/";
Connection.Response response = Jsoup.connect(url)
.method(Connection.Method.GET)
.execute();
Document responseDocument = response.parse();
Map<String, String> loginCookies = response.cookies();
Element eventValidation = responseDocument.select("input[name=__EVENTVALIDATION]").first();
String validationKey = eventValidation.attr("value");
Element viewState = responseDocument.select("input[name=__VIEWSTATE]").first();
String viewStateKey = viewState.attr("value");
response = Jsoup.connect(url)
.cookies(loginCookies)
.data("__EVENTTARGET", "")
.data("__EVENTARGUMENT", "")
.data("__LASTFOCUS", "")
.data("__VIEWSTATE", viewStateKey)
.data("__VIEWSTATEENCRYPTED", "")
.data("__EVENTVALIDATION", validationKey)
.data("ctl00$content_placeholder_body$BusinessSearch1$TextBox_NameSearch", "aaa") // <- search
.data("ctl00$content_placeholder_body$BusinessSearch1$RadioButtonList_SearchType", "Corporation Name")
.data("ctl00$content_placeholder_body$BusinessSearch1$Button_Search", "Search")
.method(Connection.Method.POST)
.followRedirects(true)
.execute();
Document document = response.parse(); //search results
System.out.println(document);
} catch (IOException e) {
e.printStackTrace();
}
return totalSize;
}
protected void onProgressUpdate(Integer... progress) {
}
protected void onPostExecute(Long result) {
}
}
You would actually execute that code using something like:
TestAsyncTask t = new TestAsyncTask();
t.execute();
To get Page 2, you would have to include the following headers. This is pseudocode, obviously, you'd have to convert it to .data calls:
__EVENTTARGET = ctl00$content_placeholder_body$SearchResults1$GridView_SearchResults_Corp
__EVENTARGUMENT = Page$2
And you still need the other headers ( __VIEWSTATEENCRYPTED blank, __VIEWSTATE as above) and cookies as above.
