如何设置cookieAcceptPolicy临时NSURLSession [英] How to set cookieAcceptPolicy for ephemeral NSURLSession

问题描述

我想使用临时NSURLSessions来为我的应用程序中的多个任务提供单独的Cookie处理。这些任务不直接绑定到UI。
问题：无论我做什么，临时NSHTTPCookieStorage的cookieAcceptPolicy保持 NSHTTPCookieAcceptPolicyNever 。

I am trying to use ephemeral NSURLSessions to provide separate cookie handling for several tasks within my app. These tasks are not directly bound to a UI. Problem: Whatever I do, the cookieAcceptPolicy of the ephemeral NSHTTPCookieStorage remains NSHTTPCookieAcceptPolicyNever.

这是我的代码：

// use a pure in-memory configuration with its own private cache, cookie, and credential store
__block NSURLSessionConfiguration* config = [NSURLSessionConfiguration ephemeralSessionConfiguration];

// do anything to accept all cookies
config.HTTPShouldSetCookies = YES;
config.HTTPCookieAcceptPolicy = NSHTTPCookieAcceptPolicyAlways;
config.HTTPCookieStorage.cookieAcceptPolicy = NSHTTPCookieAcceptPolicyAlways;

__block NSURLSession* session = [NSURLSession sessionWithConfiguration:config];

NSURLSessionDataTask* task = [session dataTaskWithURL:[NSURL URLWithString:@"https://test.cgmlife.com/Catalogs"]
                                    completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
                                        NSHTTPCookieStorage* cookies = session.configuration.HTTPCookieStorage;
                                        NSLog(@"%@", cookies);
                                        NSLog(@"%lu", cookies.cookieAcceptPolicy);
                                    }];
[task resume];

NSLog的输出总是：

The output from NSLog is always:

Ephemeral <NSHTTPCookieStorage cookies count:0>
1

其中1是NSHTTPCookieAcceptPolicyNever的值（NSHTTPCookieAcceptPolicyAlways的预期值为0）。

where 1 is the value for NSHTTPCookieAcceptPolicyNever (expected 0 for NSHTTPCookieAcceptPolicyAlways). The headers in the response are there.

我可以做什么让NSHTTPCookieStorage记住我的Cookie，而会话仍然存在？我不需要，也不想要任何持久性。

What can I do to have the NSHTTPCookieStorage remember my cookies while the session is alive? I don't need and don't want any persistence. I just want to keep cookies in memory so that they are reused for further requests in the same session.

推荐答案

它看起来像短暂的会话不存储Cookie。 eskimo1在devforums 上说：

It looks like ephemeral sessions don't store cookies ever. eskimo1 says on the devforums:

ISTR，临时会话配置不按照
所期望的基于文档的方式工作。我从来没有到过
看这个细节，但似乎你有。你应该提交
一个关于这个的错误;实施和文档清楚地显示出
的同步，因此其中一个需要修复。

ISTR that ephemeral session configurations don't work the way that folks expect based on the documentation. I never got around to looking at this in detail but it seems like you have. You should file a bug about this; the implementation and documentation are clearly out of sync, so one of them needs to be fixed.
