Hi, all, I want to set a cookie for a url, the cookie comes from a cookie string, I don't know what the format of the cookie string is supposed to be, should be like this ?? "NAME=VALUE; expires=DATE; path=PATH; domain=DOMAIN_NAME " , is there any standard to comply with ? I also have another question. In mac os x, there is a class named "NSHTTPCookie", I'm a little confused with how to use it. I googled a example like this. void setCookies(Document* /*document*/, const KURL& url, const KURL& policyBaseURL, const String& cookieStr) 64 { 65 BEGIN_BLOCK_OBJC_EXCEPTIONS; 66 67 // <rdar://problem/5632883> On 10.5, NSHTTPCookieStorage would happily store an empty cookie, which would be sent as "Cookie: =". 68 if (cookieStr.isEmpty()) 69 return; 70 71 NSURL *cookieURL = url; 72 73 // <http://bugs.webkit.org/show_bug.cgi?id=6531>, <rdar://4409034> 74 // cookiesWithResponseHeaderFields doesn't parse cookies without a value 75 String cookieString = cookieStr.contains('=') ? cookieStr : cookieStr + "="; 76 77 NSArray *cookies = [NSHTTPCookie cookiesWithResponseHeaderFields:[NSDictionary dictionaryWithObject:cookieString forKey:@"Set-Cookie"] forURL:cookieURL]; 78 [[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookies:cookies forURL:cookieURL mainDocumentURL:policyBaseURL]; 79 80 END_BLOCK_OBJC_EXCEPTIONS; 81 } In the example, I guess the "cookieStr" is my "cookie string", but when I pass a string "safarname=safarivalue; expires=Thu, 2 Aug 2009 20:47:11 UTC; path=/; domain=example.com " to it, the method "cookiesWithResponseHeaderFields:" can't parse it into a cookie successfully, so can not return a cookie array, also, the method "setCookies:" failed, is there any problem with my cookie string ? Bless my poor English, I wish I make my mind clear. Thanks in advance && thanks for your time.
