AFNetworking和Cookies [英] AFNetworking and Cookies

问题描述

我将AFNetworking用作iPhone应用程序的网络层，该网络层连接到使用Devise进行身份验证的Rails服务器。如果我登录（提供POST呼叫）并提供用户名/密码，那么之后执行的任何GET操作都可以。

I'm using AFNetworking as a network layer for my iPhone app which connects to a Rails server that uses Devise for authentication. If I sign in (with a POST call) providing username/password then after that any GET I perform is ok.

如果我关闭应用程序（而不仅仅是后台），则

If I close the app (not just background) then all my GET requests fail because I guess they're not authenticated.

所以我认为cookie存储在某个地方；有没有一种方法可以将它们保存在 NSUserDefaults 或类似的目录中，以便避免始终登录？

So I presume cookies are stored somewhere; is there a way to save them in NSUserDefaults or somewhere like that in order to avoid logging in all the time?

推荐答案

对于特定服务器上的任何后续请求，Cookie确实会在应用程序的生命周期内自动存储。一个好的策略是将用户名和密码存储在钥匙串或 NSUserDefaults 中，如下所示：

Cookies are indeed automatically stored for the lifetime of your application for any subsequent requests on a particular server. A good strategy would be to store the username and password in the keychain or in NSUserDefaults like this:

// Setting
[[NSUserDefaults standardDefaults] setObject:username forKey:@"username"];
[[NSUserDefaults standardDefaults] synchronize];

// Getting
NSString *username = [[NSUserDefaults standardDefaults] objectForKey:@"username"];

您可能希望将其与 AFHTTPClient 在 Authorization HTTP标头中发送凭据和每个请求。

You may want to use this in combination with AFHTTPClient to send your credentials along with every request in an Authorization HTTP header.
