Question

我试图在我的HTTP请求中设置cookie 我认为下面的代码可以工作：

let request  = NSMutableURLRequest(URL: url)
request.HTTPMethod = "GET"
request.setValue("key=value;", forHTTPHeaderField: "Cookie")

但此代码无效。有没有人知道如何设置它？

Answer 1

更新了Swift 3的答案

您想查看HTTPCookieStorage。

// First
let jar = HTTPCookieStorage.shared
let cookieHeaderField = ["Set-Cookie": "key=value"] // Or ["Set-Cookie": "key=value, key2=value2"] for multiple cookies
let cookies = HTTPCookie.cookies(withResponseHeaderFields: cookieHeaderField, for: url)
jar.setCookies(cookies, for: url, mainDocumentURL: url)

// Then
var request = URLRequest(url: url)

swift 2的原始答案

您想查看NSHTTPCookieStorage。

// First
let jar = NSHTTPCookieStorage.sharedHTTPCookieStorage()
let cookieHeaderField = ["Set-Cookie": "key=value"] // Or ["Set-Cookie": "key=value, key2=value2"] for multiple cookies
let cookies = NSHTTPCookie.cookiesWithResponseHeaderFields(cookieHeaderField, forURL: url)
jar.setCookies(cookies, forURL: url, mainDocumentURL: url)

// Then
let request  = NSMutableURLRequest(URL: url)

if let cookie = HTTPCookie(properties: [
    .domain: ".my.domain.name.com",
    .path: "/",
    .name: "myCookieNameKey",
    .value: "K324klj23KLJKH223423CookieValueDSFLJ234",
    .secure: "FALSE",
    .discard: "TRUE"
]) {
    HTTPCookieStorage.shared.setCookie(cookie)
    print("Cookie inserted: \(cookie)")
}

Answer 3

使用HTTPCookieStorage

设置cookie后，它是如何在Swift 3.x中运行的

let cookies=HTTPCookieStorage.shared.cookies(for: URL(string: cookieURL)!)
let headers=HTTPCookie.requestHeaderFields(with: cookies!)
let request  = NSMutableURLRequest(url: requestURL!)
request.allHTTPHeaderFields=headers

Answer 4

这可能对某些人有用（快速5）。避免在Swift中使用NSMutableURLRequest。而是遵循以下代码段：

func request(with url: URL) -> URLRequest {
    var request = URLRequest(url: url)

    guard let cookies = HTTPCookieStorage.shared.cookies(for: url) else {
        return request
    }

    request.allHTTPHeaderFields = HTTPCookie.requestHeaderFields(with: cookies)
    return request
}
