PHP cookie没有在uiwebview中保持设置 [英] PHP cookie is not staying set in uiwebview

问题描述

我有一个具有登录名的UIWebView。登录名是一个PHP脚本，并具有setcookie（）函数。当我登录时（在Webview中）但当我关闭应用程序（使用Webview）并重新打开它时，将设置cookie。 PHP cookie被取消设置，我必须再次登录。

I have a UIWebView which has a login. The login is a PHP script and has a setcookie() function. The cookies are set when I login (in the webview) but when I close out the app (with the webview) and reopen it. The PHP cookies get unset and I must login again.

这是PHP代码

setcookie($_SESSION['id'], $_SESSION['user_name'], time() + (86400 * 3), "/"); 
setcookie($_SESSION['pro_pic'], $_SESSION['status'], time() + (86400 * 3), "/"); 
setcookie($_SESSION['pro_pic'], $_SESSION['email'], time() + (86400 * 3), "/"); 

UIWebivew的代码

Code for UIWebivew

- (void)viewDidLoad
{
    [super viewDidLoad];

    UIWebView *webview=[[UIWebView alloc]initWithFrame:CGRectMake(0, 0, self.view.frame.size.width,self.view.frame.size.height)];

    NSString *url=@"http://server.bithumor.co/bitpicks/index1.php";
    NSURL *nsurl=[NSURL URLWithString:url];
    NSURLRequest *nsrequest=[NSURLRequest requestWithURL:nsurl];

    [webview loadRequest:nsrequest];

    webview.scrollView.bounces = NO;

    [self.view addSubview:webview];
    [self.view bringSubviewToFront:webview];
}

在普通的Safari浏览器中，cookie保持不变并可以正常工作。但是在UIWebView中不起作用。

On the normal safari web browser, the cookies stay set and work perfectly. But it doesn't work in the UIWebView.

我使用哪些Objective-c（仅）代码来保持PHP cookie的设置，这样我就不必再次登录？

推荐答案

如此处指出保持UIWebView中丢失php会话cookie 我更新了您的代码：

as pointed here Keep losing php session cookie in UIWebView I updated your code:

- (void)viewDidLoad
{
    [super viewDidLoad];

    UIWebView *webview=[[UIWebView alloc]initWithFrame:CGRectMake(0, 0, self.view.frame.size.width,self.view.frame.size.height)];

    NSString *url=@"http://server.bithumor.co/bitpicks/index1.php";
    NSURL *nsurl=[NSURL URLWithString:url];
    NSMutableURLRequest *nsrequest=[NSMutableURLRequest requestWithURL:nsurl];

    NSString *cookiesSaved = [[NSUserDefaults standardUserDefaults] objectForKey:@"cookies"];

    NSMutableString *cookieStringToSet = (cookiesSaved ? [NSMutableString stringWithString:cookiesSaved] : [NSMutableString new]);

    NSArray *cookiesToSet = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookiesForURL:nsurl];
    for (NSHTTPCookie *cookie in cookiesToSet) {

        if ([cookieStringToSet rangeOfString:cookie.name].location == NSNotFound)
        {
            [cookieStringToSet appendFormat:@"%@=%@;", cookie.name, cookie.value];
        }
    }

    [[NSUserDefaults standardUserDefaults] setObject:cookieStringToSet forKey:@"cookies"];
    [[NSUserDefaults standardUserDefaults] synchronize];

    [webview loadRequest:nsrequest];

    webview.scrollView.bounces = NO;

    [self.view addSubview:webview];
    [self.view bringSubviewToFront:webview];
}
