java - Attemping to manipulate data entry for a web page using jsoup -


i attempting enter data web site. post important snippet of web site here, target web page can found here

the values street address number , street name represented inpnumber , inpstreet.

html:

<td width="48">    <input type="text" id="inpnumber" name="inpnumber" class="input" size="5" value="" onkeypress="clearaction(this)" />  </td>    <td width="40">    <input type="text" id="inpunit" name="inpunit" class="input" size="4" value="" onkeypress="clearaction(this)" />  </td>    <td width="160">    <input type="text" id="inpstreet" name="inpstreet" class="input" size="20" value="" onkeypress="clearaction(this)" />  </td>

only inpstreet , inpnumber needed effective query , need enter these values.

what have tried far:

string url = "http://icare.fairfaxcounty.gov/ffxcare/search/commonsearch.aspx?mode=address";     try {     connection.response response = jsoup.connect(url)                 .useragent("mozilla/5.0")                 .timeout(10 * 10000)                 .method(connection.method.post)                 .data("inpnumber", "4127")                 .data("inpunit", "")                 .data("inpstreet", "winter harbor")                 .data("btsearch", "")                 .data("inpsuffix1", "")                 .followredirects(true)                 .execute();      //parse document response     document document = response.parse();     system.out.println(" extracting information site ");      filewriter fw = new filewriter("doc.html");     bufferedwriter bw = new bufferedwriter(fw);     bw.write(document.html());     bw.close(); } catch (exception ex){     ex.printstacktrace(); }

i have tried several variations on above code, including more/less key/pair values (setting , returning "" values found looking @ firebug), looking @ return values , general changes jsoup.connect(url) call.

the result in doc.html file original unaltered page. doing wrong?

the information being sent payload , best way use send information using requestbody(string). code below tested working.

imports:

import java.io.bufferedwriter; import java.io.filewriter;  import org.jsoup.*; import org.jsoup.nodes.document; import org.jsoup.select.elements;  import static java.net.urlencoder.encode;

code:

public static void main(string[] args) {     string url = "http://icare.fairfaxcounty.gov/ffxcare/search/commonsearch.aspx?mode=address";     string useragent = "mozilla/5.0 (windows nt 6.1; win64; x64; rv:55.0) gecko/20100101 firefox/55.0";      try {          // required information validation         // note might want make method out of , call whenever need instead of         elements inputs = jsoup.connect(url)                 .useragent(useragent)                 .get().select("input");          string eventvalidation = encode(inputs.select("#__eventvalidation").attr("value"), "utf-8");         string viewstategen = encode(inputs.select("#__viewstategenerator").attr("value"), "utf-8");         string viewstate = encode(inputs.select("#__viewstate").attr("value"), "utf-8");           int number = 4127;         string street = encode("winter harbor", "utf-8");          // not necessary         string unit = "";         string suffix = "";          document document = jsoup.connect(url)                 .useragent(useragent)                 .requestbody(                         string.format(                                 "mode=address"                                 + "&__viewstate=%s"                                 + "&__viewstategenerator=%s"                                 + "&__eventvalidation=%s"                                 + "&inpnumber=%d"                                 + "&inpunit=%s"                                 + "&inpstreet=%s"                                 + "&inpsuffix1=%s",                                  viewstate, viewstategen, eventvalidation,                                 number, unit, street, suffix))                 .post();           system.out.println("extracting information site...");          filewriter fw = new filewriter("doc.html");         bufferedwriter bw = new bufferedwriter(fw);         bw.write(document.html());         bw.close();          system.out.println("done.");     } catch (exception ex) {         //todo handle exceptions         ex.printstacktrace();     }  }

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now...
