uiwebview cookie登录 iOS UIWebView 通过 cookie 完成自动登录实例
LFYPhoenix 人气:0想了解iOS UIWebView 通过 cookie 完成自动登录实例的相关内容吗，LFYPhoenix在本文为您仔细讲解uiwebview cookie登录的相关知识和一些Code实例，欢迎阅读和指正，我们先划重点：uiwebview,cookie登录,uiwebview,cookie,ios,uiwebview,cookie，下面大家一起来学习吧。
1、相关介绍
iOS在UIWebView中获取的cookie的方法：NSHTTPCookieStorage * nCookies = [NSHTTPCookieStorage sharedHTTPCookieStorage];
再具体获取某个域的cookie：NSArray* cookiesURL = [nCookies cookiesForURL:[NSURL URLWithString:@"你的URL"]];
通过[[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:userCookie]方法将 cookies来保存起来，但是这样虽然可以保存cookies但是你应用退出之后还是会丢失(其实是cookies过期的问题)，做好的方法是把cookies放到NSUserDefaults保存起来.
2、实现
1.在UIWebView的代理方法中实现获取cookies并将cookies放到NSUserDefaults保存起来：- (void)webViewDidFinishLoad:(UIWebView*)webView中写入
- (void)webViewDidFinishLoad:(UIWebView*)webView{
NSArray *nCookies = [[NSHTTPCookieStoragesharedHTTPCookieStorage] cookies];
for (NSHTTPCookie *cookie in nCookies){
if ([cookie isKindOfClass:[NSHTTPCookie class]]){
if ([cookie.name isEqualToString:@"PHPSESSID"]) {
NSNumber *sessionOnly =[NSNumber numberWithBool:cookie.sessionOnly];
NSNumber *isSecure = [NSNumber numberWithBool:cookie.isSecure];
NSArray *cookies = [NSArray arrayWithObjects:cookie.name, cookie.value, sessionOnly, cookie.domain, cookie.path, isSecure, nil];
[[NSUserDefaults standardUserDefaults] setObject:cookies forKey:@"cookies"];
break;
}
}
}
}
2.获取cookies：运行之后，UIWebView加载url之前获取保存好的cookies，并设置cookies，
NSArray *cookies =[[NSUserDefaults standardUserDefaults] objectForKey:@"cookies"];
if (cookies.count >0) {
NSMutableDictionary *cookieProperties = [NSMutableDictionarydictionary];
[cookieProperties setObject:[cookies objectAtIndex:0] forKey:NSHTTPCookieName];
[cookieProperties setObject:[cookies objectAtIndex:1] forKey:NSHTTPCookieValue];
[cookieProperties setObject:[cookies objectAtIndex:3] forKey:NSHTTPCookieDomain];
[cookieProperties setObject:[cookies objectAtIndex:4] forKey:NSHTTPCookiePath];
NSHTTPCookie *cookieuser = [NSHTTPCookiecookieWithProperties:cookieProperties];
[[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:cookieuser];
}
注意：要在[self.webView loadRequest:req];之前设置获取cookies！
