UIWebview 启用cookies-移动开发问题

UIWebview enable cookies(UIWebview 启用cookies)

本文介绍了UIWebview 启用cookies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

我正在尝试通过 UIWebView 访问需要 cookie 的特定 URL，但我无法访问它，因为 cookie 被禁用.所以我做了以下事情:

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:

启用 cookie:

Enabled cookies:

NSHTTPCookieStorage *cookieStorage = [NSHTTPCookieStorage sharedHTTPCookieStorage];

[cookieStorage setCookieAcceptPolicy:NSHTTPCookieAcceptPolicyAlways];

创建 NSURLConnection 并从响应中提取 cookie:

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];

但这都没有帮助.但是，如果我在 safari 中启动 URL，它会成功加载，之后我也可以在 UIWebView 中加载相同的 URL.你能帮我解决这个问题，我怎样才能为 UIWebView 启用 cookie?

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?

推荐答案

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

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];

并添加addCookies:forRequest方法

- (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"];
        }
    }
}
