Do UIWebView and NSURLConnection share cookie stor

问题:

I'm building an iOS app that uses Google App Engine for the backend. Google provides an HTML login site that stores an authentication cookie. If I visit that site in a UIWebView, and the user logs in, will those cookies be in storage where they will be picked up by a NSURLConnection when making a request to the same site?

回答1:

The cookie of the UIWebView will be stored in a sandboxed cookie storage accessible through NSHTTPCookieStorage sharedHTTPCookieStorage]. You can use this cookie storage in NSURLConnection in this way:

NSArray *cookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookiesForURL:[NSURL URLWithString:@"__YOUR_URL__"]];
NSDictionary *headers = [NSHTTPCookie requestHeaderFieldsWithCookies:cookies];
[request setAllHTTPHeaderFields:headers]; //A previously created NSMutableURLRequest

Now you can normally use the NSURLRequest in a NSURLConnection and it will send the cookies created after the login in the UIWebView
