【问题描述】：

我在 php 中有一个运行良好的 webapi。现在我想在我的应用程序中使用它。 Webapi 使用 cookie 进行身份验证。所以我第一次创建登录任务并从响应中保存 cookie。

保存任务：

function testLogin(){
 let loginUrlstring = ".../webapi/login.php"
 let passwordom = ""
 let emailem = ""

 guard let url = URL(string: loginUrlstring) else { return }

    let postString = "email=" + emailem + "&pw=" + passwordom

    var urlRequest = URLRequest(url: url)
    urlRequest.httpMethod = "POST"
    urlRequest.httpShouldHandleCookies = true
    urlRequest.httpBody = postString.data(using: String.Encoding.utf8)     

    let session = URLSession.shared
    let task = session.dataTask(with: urlRequest) { (data, response, error) in
        self.saveCookies(response: response)
        print("cookies mentve")
        print(response?.url)
    }
    task.resume()}

现在我想使用 cookie 并创建请求以获取一些数据：数据下载任务：

let probaUrl = "http://.../data.php"
let postString = "table=SomeTableName&key=someFieldID&value=20"
guard let url = URL(string: probaUrl) else { return }

loadCookies()
let cookiesArray = HTTPCookieStorage.shared.cookies
let headers = HTTPCookie.requestHeaderFields(with: cookiesArray!)


var urlRequest = URLRequest(url: url)
urlRequest.httpMethod = "GET"//"POST"
urlRequest.httpShouldHandleCookies = true
urlRequest.httpBody = postString.data(using: String.Encoding.utf8)
urlRequest.allHTTPHeaderFields = headers

var session = URLSession(configuration: .default)
session.configuration.httpCookieAcceptPolicy = .always

session.configuration.httpAdditionalHeaders = headers
let task = session.dataTask(with: urlRequest) { (data, response, error) in
    print(response)
    print(data)
    if let data2 = data, let utf8Text = String(data: data2, encoding: .utf8) {
        print("Data: \(utf8Text)") // original server data as UTF8 string
    }
}
task.resume()

它说：完成错误 - 代码：-1001 打印数据---无我的错在哪里？

【解决方案1】：

您应该打印发生的确切错误以了解问题所在我的意思是print(error) 中的let task = session.dataTask(with: urlRequest) { (data, response, error) in ...
