How to make a NSURLSesssion GET request with cookies(如何使用Cookie发出NSURLSesssion GET请求)
本文介绍了如何使用Cookie发出NSURLSesssion GET请求的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我正在使用Pinterest SDK下载Pinterest Pin的链接(我从服务器返回的示例链接:https://www.pinterest.com/r/pin/186195765822871832/4801566892554728205/77314e40aeb26c0dc412e9cfa82f8dccc401fdb2b9806a3fe17ba8bafdb50510)。
大约5天前,当我尝试访问从Pinterest下载的类似链接时,我的NSURLSesssion中开始出现404个错误。
一位朋友说,他认为Pinterest现在必须使用cookie才能访问该链接。
如何配置我的会话,以便可以使用Cookie并从Pinterest获得200响应?
更新代码:
import UIKit
import PlaygroundSupport
var url = URL(string: "https://www.pinterest.com/r/pin/186195765822871832/4801566892554728205/77314e40aeb26c0dc412e9cfa82f8dccc401fdb2b9806a3fe17ba8bafdb50510")
var getSourceURLFromPinterest: URLSessionDataTask? = nil
let sessionConfig: URLSessionConfiguration = URLSessionConfiguration.default
sessionConfig.timeoutIntervalForRequest = 30.0
sessionConfig.timeoutIntervalForResource = 30.0
let cookieJar = HTTPCookieStorage.shared
let cookieHeaderField = ["Set-Cookie": "key=value, key2=value2"]
let cookies = HTTPCookie.cookies(withResponseHeaderFields: cookieHeaderField, for: url!)
HTTPCookieStorage.shared.setCookies(cookies, for: url, mainDocumentURL: url)
let session = URLSession(configuration: sessionConfig)
getSourceURLFromPinterest = session.dataTask(with: url! as URL) { (data: Data?, response: URLResponse?, error: Error?) -> Void in
if error != nil {
print("error is (error)")
}
if response == nil {
print("no response")
} else if let _ = data {
//Config Request
let request = NSMutableURLRequest(
url: (response?.url)!,
cachePolicy: .reloadIgnoringLocalAndRemoteCacheData,
timeoutInterval: 30.0)
request.httpMethod = "HEAD"
var statusCode = Int()
let session = URLSession.shared
let checkURLForResponse = session.dataTask(with: request as URLRequest) {urlData, myResponse, responseError in
if let httpResponse = myResponse as? HTTPURLResponse {
statusCode = httpResponse.statusCode
switch statusCode {
case _ where statusCode < 500 && statusCode > 299 && statusCode != 405: //whitelisted 405 to exclude Amazon.com false errors
print("status code (statusCode) for (url)")
default:
break;
}
} else { print("***NO httpResponse for (url)") }
}
checkURLForResponse.resume()
}
}
getSourceURLFromPinterest!.resume()

推荐答案
其他答案一般都可以,但对我来说,这就是我为了从Pinterest的服务器获得响应而对请求进行编码的方式。请注意,我认为我正在做的具体操作与Pinterest服务器中可能存在的错误有关,请参阅:https://github.com/pinterest/ios-pdk/issues/124
我注释掉了我的个人Pinterest会话ID
var cookieSession = String()
var cookieCSRFToken = String()
var myWebServiceUrl = URL(string: "https://www.pinterest.com/r/pin/186195765821344905/4801566892554728205/a9bb098fcbd6b73c4f38a127caca17491dafc57135e9bbf6a0fdd61eab4ba885")
let requestOne = URLRequest(url: myWebServiceUrl!)
let sessionOne = URLSession.shared
let taskOne = sessionOne.dataTask(with: requestOne, completionHandler: { (data, response, error) in
if let error = error {
print("ERROR: (error)")
}
else {
print("RESPONSE: (response)")
if let data = data, let dataString = String(data: data, encoding: .utf8) {
print("DATA: " + dataString)
} // end: if
var cookies:[HTTPCookie] = HTTPCookieStorage.shared.cookies! as [HTTPCookie]
print("Cookies Count = (cookies.count)")
for cookie:HTTPCookie in cookies as [HTTPCookie] {
// Get the _pinterest_sess ID
if cookie.name as String == "_pinterest_sess" {
//var cookieValue : String = "CookieName=" + cookie.value as String
cookieSession = cookie.value as String
print(cookieSession)
}
// Get the csrftoken
if cookie.name as String == "csrftoken" {
cookieCSRFToken = cookie.value
print(cookieCSRFToken)
}
} // end: for
} // end: if
})
taskOne.resume()
var requestTwo = URLRequest(url: myWebServiceUrl!)
cookieSession = "XXXXXXXX"
cookieCSRFToken = "JHDylCCKKNToE4VXgofq1ad3hg06uKKl"
var cookieRequest = "_auth=1; _b="AR4XTkMmqo9JKradOZyuMoSWcMdsBMuBHHIM21wj2RPInwdkbl2yuy56yQR4iqxJ+N4="; _pinterest_pfob=disabled; _pinterest_sess="" + cookieSession + ""; csrftoken=" + cookieCSRFToken as String
requestTwo.setValue(cookieRequest as String, forHTTPHeaderField: "Cookie")
let taskTwo = sessionOne.dataTask(with: requestTwo, completionHandler: { (data, response, error) in
if let error = error {
print("ERROR: (error)")
}
else {
print("RESPONSE: (response)")
} // end: if
})
taskTwo.resume()
PlaygroundPage.current.needsIndefiniteExecution = true
