在UIWebView中启用Cookies [英] Enable Cookies in UIWebView

问题描述

如何在使用UIWebView窗口的iPhone应用程序中启用cookie，以便登录系统正常工作？

How can I enable cookies in my iPhone Application that uses a UIWebView Window, so that my login system will work?

推荐答案

确保以

[NSHTTPCookieStorage sharedHTTPCookieStorage].cookieAcceptPolicy = 
    NSHTTPCookieAcceptPolicyAlways;

但是，正如@JoelFan所提到的，问题可能是您的用户代理字符串导致ASP.NET尝试并以无cookie登录失败。而不是包含

But, as mentioned by @JoelFan, the issue may be your User Agent string causing ASP.NET to attempt and fail at a cookieless login. Instead of a response that includes

Set-Cookie的响应：.ASPXAUTH = really-long-hex-number

它返回重定向到类似

位置：/（F（ long-sorta-base64ish-looking-string ））/

默认的UIWebView用户代理字符串类似于

The default UIWebView user agent string is something like

User-Agent：Mozilla / 5.0（iPad； CPU OS 7_0_2，例如Mac OS X）AppleWebKit / 537.51.1（KHTML，像Gecko一样）Mobile / 11A501

User-Agent: Mozilla/5.0 (iPad; CPU OS 7_0_2 like Mac OS X) AppleWebKit/537.51.1 (KHTML, like Gecko) Mobile/11A501

，但是ASP.NET不喜欢这样。 Safari发送以下内容：

but ASP.NET doesn't like this. Safari sends something like this:

用户代理：Mozilla / 5.0（iPad； CPU OS 7_0_2，例如Mac OS X）AppleWebKit / 537.51。 1（KHTML，如Gecko）版本/7.0 移动版/ 11A501 Safari / 9537.53

User-Agent: Mozilla/5.0 (iPad; CPU OS 7_0_2 like Mac OS X) AppleWebKit/537.51.1 (KHTML, like Gecko) Version/7.0 Mobile/11A501 Safari/9537.53

尽早执行以下操作，也许在您的AppDelegate.m中。

Do the following early on, maybe in your AppDelegate.m

// DON'T try to reuse a UIWebView for this. 
UIWebView *wv = [[UIWebView alloc] initWithFrame:CGRectZero];
// This webview has already decided to use the default user agent string.

// let's use javascript to get the existing user agent string
NSString *userAgent = [wv stringByEvaluatingJavaScriptFromString:@"navigator.userAgent"];

// let's tack on some stuff to make ASP.NET happy
userAgent = [userAgent stringByAppendingString:@" Version/7.0 Safari/9537.53"];

[[NSUserDefaults standardUserDefaults] registerDefaults:@{@"UserAgent": userAgent}];
// New UIWebViews inited after here will use the user agent string you made.
