Alamofire post method in iOS Swift 4? - ios

Question

For getting push notification here i am sending postitem, token, like count and currentname using alamofire post method(pod version alamofire 4.5). I did not get any response when post method called and it does not show any errors.
I tried keeping breaking points in alamofire function, it call alamofire.requestion then it goes out function.
Here is the code tried to send post method to backend:
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
}
}
}
Getting console error like this

Answer 1

That is because you are not setting request time in your network call, by default your request time is a small interval, so please increase request timeout time. something like this,
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
}
Second mistake in your code is you are trying to access http url which are by default are not allowed so you have to by pass this security from your app, Please refer to this answer in order to remove this security layer from your app.
The resource could not be loaded because the App Transport Security policy requires the use of a secure connection
