iOS UIWebView 通过 cookie 完成自动登录实例
1、相关介绍
iOS在UIWebView中获取的cookie的方法：NSHTTPCookieStorage*nCookies=[NSHTTPCookieStoragesharedHTTPCookieStorage];
再具体获取某个域的cookie：NSArray*cookiesURL=[nCookiescookiesForURL:[NSURLURLWithString:@"你的URL"]];
通过[[NSHTTPCookieStoragesharedHTTPCookieStorage] 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*cookieinnCookies){
if([cookieisKindOfClass:[NSHTTPCookieclass]]){
if([cookie.nameisEqualToString:@"PHPSESSID"]){
NSNumber*sessionOnly=[NSNumbernumberWithBool:cookie.sessionOnly];
NSNumber*isSecure=[NSNumbernumberWithBool:cookie.isSecure];
NSArray*cookies=[NSArrayarrayWithObjects:cookie.name,cookie.value,sessionOnly,cookie.domain,cookie.path,isSecure,nil];
[[NSUserDefaultsstandardUserDefaults]setObject:cookiesforKey:@"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=[[NSUserDefaultsstandardUserDefaults]objectForKey:@"cookies"];
if(cookies.count>0){
NSMutableDictionary*cookieProperties=[NSMutableDictionarydictionary];
[cookiePropertiessetObject:[cookiesobjectAtIndex:0]forKey:NSHTTPCookieName];
[cookiePropertiessetObject:[cookiesobjectAtIndex:1]forKey:NSHTTPCookieValue];
[cookiePropertiessetObject:[cookiesobjectAtIndex:3]forKey:NSHTTPCookieDomain];
[cookiePropertiessetObject:[cookiesobjectAtIndex:4]forKey:NSHTTPCookiePath];
NSHTTPCookie*cookieuser=[NSHTTPCookiecookieWithProperties:cookieProperties];
[[NSHTTPCookieStoragesharedHTTPCookieStorage]setCookie:cookieuser];
}
注意：要在[self.webViewloadRequest:req];之前设置获取cookies！
