Question

我使用以下代码创建一个cookie，但是faild。（iOS SDK 5）

// add cookie
NSDictionary *properties = [NSDictionary dictionaryWithObjectsAndKeys:
                            req.URL, NSHTTPCookieOriginURL,
                            @"MLSTORAGE", NSHTTPCookieName,
                            @"1234567890", NSHTTPCookieValue,
                            nil];
NSHTTPCookie *cookie = [NSHTTPCookie cookieWithProperties:properties];
NSLog(@"\nurl: %@\ncookie: %@", req.URL, cookie);
[[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:cookie];
//

日志是：

2012-07-26 18:30:49.914 Motilink[15289:707] -[FMWebDAVRequest sendRequest:][Line 154] 
url: http://210.116.114.195:8080/MLServer/storage/
cookie: (null)

任何人都知道如何创建cookie吗？

将NSHTTPCookieOriginURL与您的请求的网址一起使用时似乎存在问题。

尝试使用此代码，它对我有用：

// add cookie
    NSDictionary *properties = [NSDictionary dictionaryWithObjectsAndKeys:
                                req.URL.host, NSHTTPCookieDomain,
                                req.URL.path, NSHTTPCookiePath,
                                @"MLSTORAGE", NSHTTPCookieName,
                                @"1234567890", NSHTTPCookieValue,
                                nil];
    NSHTTPCookie *cookie = [NSHTTPCookie cookieWithProperties:properties];
    NSLog(@"\nurl: %@\ncookie: %@", req.URL, cookie);
    [[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:cookie];
    //

但是，我不知道为什么NSHTTPCookieOriginURL在这里不起作用。

希望这有帮助，

要成功创建cookie，您必须为（至少）NSHTTPCookiePath，NSHTTPCookieName和NSHTTPCookieValue键以及NSHTTPCookieOriginURL键或NSHTTPCookieDomain键提供值。

我遇到了同样的问题。当我查阅文档时发现只有＆＃39; name＆＃39;，＆＃39; value＆＃39;和＆quot; originURL＆＃39;或者＆＃39;域名＆＃39;我试过要求属性，但失败了。在我添加了“路径”之后然后它奏效了。因为我还没有准确地理解，如果你只提供域名＆＃39;除了＆quot; originURL＆＃39;，＆＃39;路径＆＃39;也是必需的。

<tr>
    <th>Property key constant</th>
    <th>Type of value</th>
    <th>Required</th>
    <th>Description</th>
</tr>
<tr>
    <td>NSHTTPCookieName</td>
    <td>NSString</td>
    <td>YES</td>
    <td>Name of the cookie</td>
</tr>
<tr>
    <td>NSHTTPCookieValue</td>
    <td>NSString</td>
    <td>YES</td>
    <td>Value of the cookie</td>
</tr>
<tr>
    <td>NSHTTPCookieDomain</td>
    <td>NSString</td>
    <td>Special, a value for either NSHTTPCookieOriginURL or
    NSHTTPCookieDomain must be specified.</td>
    <td>Domain for the cookie. Inferred from the value for
    NSHTTPCookieOriginURL if not provided.</td>
</tr>
<tr>
    <td>NSHTTPCookieOriginURL</td>
    <td>NSURL or NSString</td>
    <td>Special, a value for either NSHTTPCookieOriginURL or
    NSHTTPCookieDomain must be specified.</td>
    <td>URL that set this cookie. Used as default for other fields
    as noted.</td>
</tr>
<tr>
    <td>NSHTTPCookiePath</td>
    <td>NSString</td>
    <td>NO</td>
    <td>Path for the cookie. Inferred from the value for
    NSHTTPCookieOriginURL if not provided. Default is "/".</td>
</tr>

最终代码如下：

NSMutableDictionary *cookieProperties = [NSMutableDictionary dictionary];
[cookieProperties setObject:@"SESSION" forKey:NSHTTPCookieName];
[cookieProperties setObject:@"value" forKey:NSHTTPCookieValue];
[cookieProperties setObject:@".domain.com" forKey:NSHTTPCookieDomain];
[cookieProperties setObject:@"/" forKey:NSHTTPCookiePath];
NSHTTPCookie *co = [NSHTTPCookie cookieWithProperties:cookieProperties];
[[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:co];

这可能对在NSHTTPCookieStorage中设置cookie数组很有用。我正面临这个问题，我使用下面的代码解决了。希望这对试图设置一系列cookie的人有所帮助。

 NSDictionary *cookieProperties = [NSDictionary dictionaryWithObjectsAndKeys:
                                  @".domain.com", NSHTTPCookieDomain,
                                  @"/", NSHTTPCookiePath,
                                  @"SESSION", NSHTTPCookieName,
                                  @"Session value",NSHTTPCookieValue,nil];
NSDictionary *cookieProperties1 = [NSDictionary dictionaryWithObjectsAndKeys:
                                  @".domain.com", NSHTTPCookieDomain,
                                  @"/", NSHTTPCookiePath,
                                  @"some cookie", NSHTTPCookieName,
                                  @"some cookie value",NSHTTPCookieValue,nil];

NSHTTPCookie *cookie1 = [NSHTTPCookie cookieWithProperties:cookieProperties1];
NSHTTPCookie *cookie = [NSHTTPCookie cookieWithProperties:cookieProperties];
NSArray* cookieArray = [NSArray arrayWithObjects: cookie,cookie1, nil];
[[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookies:cookieArray forURL:[NSURL   URLWithString:urlString] mainDocumentURL:nil];

您可以使用以下代码交叉验证您的Cookie。

[[[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies] enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) {

    NSLog(@"Printing cookies %@", obj);
}];

使用“NSHTTPCookie cookieWithProperties”创建cookie失败
