ios - NSHTTPCookie 无

Question

这是我的代码

    let cookieProperties = [
        NSHTTPCookieOriginURL: Constants.baseUrl,
        NSHTTPCookiePath: "/",
        NSHTTPCookieName: "device_id",
        NSHTTPCookieValue: Constants.deviceId
    ]
    let cookiePropertiesVersion = [
        NSHTTPCookieOriginURL: Constants.baseUrl,
        NSHTTPCookiePath: "/",
        NSHTTPCookieName: "app_version_code",
        NSHTTPCookieValue: "50"
    ]

    let newCookie = NSHTTPCookie(properties: cookieProperties)
    let newCookieVersion = NSHTTPCookie(properties: cookiePropertiesVersion)
    cookieStorage.setCookie(newCookie!)
    cookieStorage.setCookie(newCookieVersion!)

错误在行

cookieStorage.setCookie(newCookie!)

newCookie 为零并且

unexpectedly found nil while unwrapping an Optional value

错误来了

试试这段代码。这可能对你有帮助。发生这种情况是因为 NSHTTPCookie(properties: cookieProperties) 作为 newCookie 返回 nil，而您正试图在 cookieStorage< 中设置 nil/。

   if let newCookie = NSHTTPCookie(properties: cookieProperties){
        cookieStorage.setCookie(newCookie!)
    }
    let newCookieVersion = NSHTTPCookie(properties: cookiePropertiesVersion)
