NSHTTPCookie零

Question

這裏是我的代碼

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!) 

錯誤是在行

cookieStorage.setCookie（newCookie！）

newCookie是零和

意外發現零，同時解開一個可選v ALUE

錯誤出現

試試這個代碼。這可能會幫助你。 發生這種情況是因爲NSHTTPCookie(properties: cookieProperties)返回nil爲newCookie，而您試圖在cookieStorage中設置nil。

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