无法使用"NSHTTPCookie cookieWithProperties“创建cookie

Question

我使用下面的代码来创建cookie，但是失败了。(IOS SDK5)

// 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];
//

日志为：

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)

有人知道如何创建cookie吗？

似乎在将NSHTTPCookieOriginURL与请求的URL一起使用时出现了问题。

试着使用下面的代码，它对我很有效：

// 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];
    //

然而，我不知道为什么NSHTTPCookieOriginURL不能在这里工作。

希望这能帮上忙

要成功创建cookie，必须提供(至少) NSHTTPCookiePath、NSHTTPCookieName和NSHTTPCookieValue密钥以及NSHTTPCookieOriginURL密钥或NSHTTPCookieDomain密钥的值。

我也遇到过同样的问题。当我查阅文档，发现只有'name'，'value‘和'originURL’或'domain‘属性是必需的时，我尝试了，但失败了。在我添加了'path‘之后，它就起作用了。因为我没有准确地理解，如果你只提供了'domain‘而不是'originURL'，'path’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];
