Ios 是否可以使用 sharedHTTPCookieStorage 为 UIWebView 手动设置 cookie

发布于05月11日

我在iOS应用程序中有需要身份验证Cookie才能正确进行身份验证的Web视图.我正在寻找一种方法，可以在iOS应用程序的网络视图中设置cookie，而不必发出设置cookie的出站请求，因为我已经在客户端上有身份验证信息.

这post个向我们展示了UIWebView cookie的存储位置.

现在，我正在加载一个隐藏的Web视图来发出出站请求，但我不希望必须发出设置简单cookie的外部请求.

推荐答案

是的，你可以做到的.首先，在application ationDidBecomeActive中添加此行

[[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookieAcceptPolicy:NSHTTPCookieAcceptPolicyAlways];

CookieAcceptPolicy在应用程序之间共享，并且可以在您不知情的情况下进行更改，因此您需要确保每次运行应用程序时都拥有所需的接受策略.

然后，要设置Cookie，请执行以下操作:

NSMutableDictionary *cookieProperties = [NSMutableDictionary dictionary];
[cookieProperties setObject:@"testCookie" forKey:NSHTTPCookieName];
[cookieProperties setObject:@"someValue123456" forKey:NSHTTPCookieValue];
[cookieProperties setObject:@"www.example.com" forKey:NSHTTPCookieDomain];
[cookieProperties setObject:@"www.example.com" forKey:NSHTTPCookieOriginURL];
[cookieProperties setObject:@"/" forKey:NSHTTPCookiePath];
[cookieProperties setObject:@"0" forKey:NSHTTPCookieVersion];

// set expiration to one month from now or any NSDate of your choosing
// this makes the cookie sessionless and it will persist across web sessions and app launches
/// if you want the cookie to be destroyed when your app exits, don't set this
[cookieProperties setObject:[[NSDate date] dateByAddingTimeInterval:2629743] forKey:NSHTTPCookieExpires];

NSHTTPCookie *cookie = [NSHTTPCookie cookieWithProperties:cookieProperties];
[[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:cookie];

此cookie的名称为testCookie，值为someValue123456，将与任何http请求一起发送到www.example.通用域名格式.

关于设置cookies 的一个大警告，请看我的问题！

NSHTTPCookieStorage state not saved on app exit. Any definitive knowledge/documentation out there?个
