Hello,
I am trying to get information from a website with post method but I cannot
get the right content. This is the website. I should get the bus schedule
which is displayed after you enter number in the field on the first page.HTML
Code:
http://wbus.talktrack.com/
. Here is the code of the website:Code:
<html><body>
<form id="Form1" name="Form1" method="post" action="wap.aspx?__ufps=666968">
<input type="hidden" name="__EVENTTARGET" value="">
<input type="hidden" name="__EVENTARGUMENT" value="">
<script language=javascript><!--
function __doPostBack(target, argument){
var theform = document.Form1
theform.__EVENTTARGET.value = target
theform.__EVENTARGUMENT.value = argument
theform.submit()
}
// -->
</script>
<div align="Center"><img src="img/waplogo.gif" alt="LPP" border="0" /><br>
LPP - Napoved prihodov avtobusov.<br>
Vnesite ime postaje<br>
<input name="tb_postaja"/><br>
<input name="b_send" type="submit" value="Prikaži"/><br>
<a href="wap.aspx?culture=sl-SI">slo</a>
|
<a
href="wap.aspx?culture=en-GB">eng</a></div></form></body></html>
When you enter the number into the field you should get the bus schedule.
Here is my code:Code:
NSString *post = @"tb_postaja=163";
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding
allowLossyConversion:NO];
NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]];
NSMutableURLRequest *urlRequest = [[[NSMutableURLRequest alloc] init]
autorelease];
NSString *testString =@"http://wbus.talktrack.com/";;
//testString = [testString stringByAppendingString:string2];
[urlRequest setURL:[NSURL URLWithString:testString]];
[urlRequest setHTTPMethod:@"POST"];
[urlRequest setValue:postLength forHTTPHeaderField:@"Content-Length"];
[urlRequest setValue:@"application/x-www-form-urlencoded"
forHTTPHeaderField:@"Content-Type"];
[urlRequest setHTTPBody:postData];
NSData *urlData;
NSURLResponse *response;
NSError *error;
urlData = [NSURLConnection sendSynchronousRequest:urlRequest
returningResponse:&response error:&error];
NSLog(@"Succeeded! Received %d bytes of data",[urlData length]);
NSString *aStr = [[NSString alloc] initWithData:urlData
encoding:NSASCIIStringEncoding];
NSLog(aStr);
.
Thanks in advance.
