使用未解析的標識符“response”（在“”“dataTask.resume()”“”之后）

Question

我想我需要在別處寫我的 class 但我不知道在哪里。 錯誤顯示在最后dataTask.resume()之后的行上。

let postData = NSMutableData(data: "email=hello@test.com".data(using: String.Encoding.utf8)!)
postData.append("&password=12345".data(using: String.Encoding.utf8)!)
postData.append("&loginbutton=Connecter".data(using: String.Encoding.utf8)!)

let request = NSMutableURLRequest(url: NSURL(string: "https://zzzway.com/appMango/login.php")! as URL,
                                        cachePolicy: .useProtocolCachePolicy,
                                    timeoutInterval: 10.0)
request.httpMethod = "POST"
request.allHTTPHeaderFields = headers
request.httpBody = postData as Data

let session = URLSession.shared
let dataTask = session.dataTask(with: request as URLRequest, completionHandler: { (data, response, error) -> Void in
  if (error != nil) {
    print(error)
  } else {
    let httpResponse = response as? HTTPURLResponse
    print(httpResponse)
  }
})
 dataTask.resume()

    let httpResponse = response as? HTTPURLResponse
    if httpResponse.contains("chute")
    {
    print("exists")
    }

Answer 1

這個

let httpResponse = response as? HTTPURLResponse
if httpResponse.contains("chute") {
     print("exists")
}

應該在completionHandler里面

完成你需要做的事

if let str = response?.url?.absoluteString , str.contains("chute") {

}
