UIWebview启用Cookie | UIWebview启用Cookie

本文介绍了UIWebview启用Cookie的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我尝试通过 UIWebView 访问需要Cookie的特定网址，但我无法访问它，因为Cookie已停用。所以我做了以下事情：

<$>

p> NSHTTPCookieStorage * cookieStorage = [NSHTTPCookieStorage sharedHTTPCookieStorage]; [cookieStorage setCookieAcceptPolicy：NSHTTPCookieAcceptPolicyAlways];

创建 NSURLConnection 来自回应：

  NSArray * cookies = [NSHTTPCookie cookiesWithResponseHeaderFields：[httpResponse allHeaderFields] forURL：response.URL]; 
 
 [[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookies：cookies forURL：response.URL mainDocumentURL：nil];

但这两个都没有帮助。但是，如果我在safari中启动URL成功加载后，我可以加载相同的URL在 UIWebView 。

您可以帮我解决这个问题，如何为 UIWebView

解决方案

创建 NSURLRequest 后，将sharedHTTPCookieStorage中的所有Cookie复制到 NSURLRequest ：

  NSArray * cookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies]; 
 
 NSMutableURLRequest * request = [NSMutableURLRequest requestWithURL：url]; 
 [request setHTTPShouldHandleCookies：YES]; 
 [self addCookies：cookies forRequest：request]; 
 [_webView loadRequest：request];

并添加 addCookies：forRequest p>

   - （void）addCookies：（NSArray *）cookies forRequest：（NSMutableURLRequest *）request 
 {
 if （[cookies count]> 0）
 {
 NSHTTPCookie * cookie; 
 NSString * cookieHeader = nil; 
 for（cookie in cookie）
 {
 if（！cookieHeader）
 {
 cookieHeader = [NSString stringWithFormat：@％@ =％@，[ name]，[cookie value]]; 
} 
 else 
 {
 cookieHeader = [NSString stringWithFormat：@％@;％@ =％@，cookieHeader，[cookie name]，[cookie value]]; 
} 
} 
 if（cookieHeader）
 {
 [request setValue：cookieHeader forHTTPHeaderField：@Cookie]; 
} 
} 
}

I am trying to access a specific URL that requires cookies through UIWebView but I can not access it because cookies are disabled. So I did the following:

Enabled cookies:

NSHTTPCookieStorage *cookieStorage = [NSHTTPCookieStorage sharedHTTPCookieStorage];

[cookieStorage setCookieAcceptPolicy:NSHTTPCookieAcceptPolicyAlways];

Created NSURLConnection and extracted cookies from response:

NSArray *cookies = [ NSHTTPCookie cookiesWithResponseHeaderFields: [ httpResponse allHeaderFields ] forURL:response.URL];

[[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookies: cookies forURL: response.URL mainDocumentURL:nil];

But neither of this didn't help. However if I launch the URL in safari it loads successfully and after that I can load the same URL in UIWebView too. Could you help me with this, how can I enable cookies for UIWebView?

Thanks in advance

解决方案

After create a NSURLRequest, copy all cookies in sharedHTTPCookieStorage to NSURLRequest:

NSArray *cookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies];

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPShouldHandleCookies:YES];
[self addCookies:cookies forRequest:request];
[_webView loadRequest:request];

And add addCookies:forRequest method

- (void)addCookies:(NSArray *)cookies forRequest:(NSMutableURLRequest *)request
{
    if ([cookies count] > 0)
    {
        NSHTTPCookie *cookie;
        NSString *cookieHeader = nil;
        for (cookie in cookies)
        {
            if (!cookieHeader)
            {
                cookieHeader = [NSString stringWithFormat: @"%@=%@",[cookie name],[cookie value]];
            }
            else
            {
                cookieHeader = [NSString stringWithFormat: @"%@; %@=%@",cookieHeader,[cookie name],[cookie value]];
            }
        }
        if (cookieHeader)
        {
            [request setValue:cookieHeader forHTTPHeaderField:@"Cookie"];
        }
    }
}
