alamofire httprequest swift ios

为了在这里获得推送通知,我使用alamofire post方法(pod版本alamofire 4.5)发送positem、token,比如count和currentname。调用post方法时,我没有得到任何响应,它也没有显示任何错误。我尝试在alamofire函数中保留断点,它调用alamofire.requestion,然后退出函数。

以下是试图将post方法发送到后端的代码:

  func postNotification(postItem: String, post: Post) {

    print("Get token from post:::",post.token)
    print(postItem)
    let token = UserDefaults.standard.string(forKey: "token")




    let headers: HTTPHeaders = ["Content-Type" :"application/x-www-form-urlencoded"]

       let parameters : [String:Any] = ["count":post.likeCount!, "likedby":currentName, "postId=":postItem, "token": post.token!]
    Alamofire.request("http://highavenue.co:9000/likesnotification/", method: .post, parameters: parameters, encoding: JSONEncoding.default, headers: nil).responseJSON { (response:DataResponse<Any>) in

        switch(response.result) {
        case .success(_):
            if let data = response.result.value{
                print(data)
            }
            break

        case .failure(_):
            print(response.result.error as Any)
            break

        }
    }

}

像这样获取控制台错误

let request = NSMutableURLRequest(url: URL(string: "")!)
request.httpMethod = "POST"
request.setValue("application/json", forHTTPHeaderField: "Content-Type")
request.timeoutInterval = 120 // 120 secs
let values = ["key": "value"]
request.httpBody = try! JSONSerialization.data(withJSONObject: values, options: [])
Alamofire.request(request as! URLRequestConvertible).responseJSON {
    response in
    // do whatever you want here
}

代码中的第二个错误是您试图访问 http url 默认情况下是不允许的,因此您必须从应用程序中绕过此安全性,请参考此答案以便从应用程序中删除此安全层。 The resource could not be loaded because the App Transport Security policy requires the use of a secure connection
