Swift NSHTTPCookieStorage计数:2

Question

var httpCookie:NSHTTPCookieStorage=NSHTTPCookieStorage.sharedHTTPCookieStorage();
println(httpCookie)

<NSHTTPCookieStorage cookies count:2>

我怎么才能给它循环一个cookie呢？

Answer 1

看看这段代码

var cookies:[NSHTTPCookie] = NSHTTPCookieStorage.sharedHTTPCookieStorage().cookies as [NSHTTPCookie]
for cookie:NSHTTPCookie in cookies as [NSHTTPCookie] {
    if cookie.name as String == "CookieName" {
        var cookieValue : String = "CookieName=" + cookie.value! as String

        //if you want to add to your request
        youRequest.setValue(cookieValue, forHTTPHeaderField: "cookie")
    }
}

Answer 2

使用Swift 5中的URLSession，可以简洁地遍历返回的Cookie...

URLSession.shared.dataTask(with: url) { (data, resp, error) in

if let response = resp as? HTTPURLResponse {
    print("Status Code \(response.statusCode)")

    if let cookies:[HTTPCookie] = HTTPCookieStorage.shared.cookies{
        for cookie:HTTPCookie in cookies as [HTTPCookie] {
            // logic here...
        }
    }
}

记住，cookies可能已经在商店里了。如果你想要一个可靠的计数，在你发送请求之前，确保清理Cookie商店...

HTTPCookieStorage.shared.deleteCookie(cookie: HTTPCookie)
