Hi All
I have been working using openFrameworks, on a problem that is posted on the forum: www.openframeworks.cc/forum/viewtopic.php?f=8&t=4765
Essentially, I have used an an set of files, ofxHttpUtils, which uses poco to post to web forms. The example code I have used is at: github.com/arturoc/ofxHttpUtils/blob/gh-pages/example/src/testApp.cpp
I want to POST to a login page, a username and password, and then I am aiming to scrape text off the response... that's the aim, via an iPhone app.
The problem I am having is cookies. The ofxHttpUtils addon does not have any method for remembering the cookie from a POST, so the response I get back is just the login page. I have searched for methods to try and capture the cookie, and there seems to be something in Objective C here, from another post to Stack Overflow:
NSHTTPURLResponse * response;
NSError * error;
NSMutableURLRequest * request;
request = [[[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:@"http://temp/gomh/authenticate.py?setCookie=1"]
cachePolicy:NSURLRequestReloadIgnoringCacheData
timeoutInterval:60] autorelease];
[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSLog(@"RESPONSE HEADERS: \n%@", [response allHeaderFields]);
// If you want to get all of the cookies:
NSArray * all = [NSHTTPCookie cookiesWithResponseHeaderFields:[response allHeaderFields] forURL:[NSURL URLWithString:@"http://temp"]];
NSLog(@"How many Cookies: %d", all.count);
// Store the cookies:
// NSHTTPCookieStorage is a Singleton.
[[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookies:all forURL:[NSURL URLWithString:@"http://temp"] mainDocumentURL:nil];
// Now we can print all of the cookies we have:
for (NSHTTPCookie *cookie in all)
NSLog(@"Name: %@ : Value: %@, Expires: %@", cookie.name, cookie.value, cookie.expiresDate);
// Now lets go back the other way. We want the server to know we have some cookies available:
// this availableCookies array is going to be the same as the 'all' array above. We could
// have just used the 'all' array, but this shows you how to get the cookies back from the singleton.
NSArray * availableCookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookiesForURL:[NSURL URLWithString:@"http://temp"]];
NSDictionary * headers = [NSHTTPCookie requestHeaderFieldsWithCookies:availableCookies];
// we are just recycling the original request
[request setAllHTTPHeaderFields:headers];
request.URL = [NSURL URLWithString:@"http://temp/gomh/authenticate.py"];
error = nil;
response = nil;
NSData * data = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSLog(@"The server saw:\n%@", [[[NSString alloc] initWithData:data encoding: NSASCIIStringEncoding] autorelease]);
I am not sure how/where to implement this, so that I can integrate with my my ofxHttpUtils code so that the cookie is remembered and served in calls to the password protected site. Can anyone help? I know this request is a little unspecific... I hope you can see what I'm trying to do...
