Request time out error 1001 using alamofire in ios swift?

Here i am sending parameter value like username, user toke, post id, etc to backend using alamofire. if status success then, notification will will send from backend. Inside postnotification function i have tried post method code using alamofire and datatask method but it does not work. In console i am getting request time out or nothing.

Here is my code :

   func postNotification(postItem: String, post: Post) {    //                declare parameter as a dictionary which contains string as key and value combination. considering inputs are valid        print("Get token from post:::",post.token)     print(postItem)     let token = UserDefaults.standard.string(forKey: "token")             //create the url with URL       var parameters       = [String:Any]()      parameters["count"]  = post.likeCount!     parameters["likedby"]  = currentName     parameters["postId"] = postItem     parameters["token"] = post.token!      let Url = String(format: "http://highavenue.co:9000/likesnotification")     guard let serviceUrl = URL(string: Url) else { return }     //        let loginParams = String(format: LOGIN_PARAMETERS1, "test", "Hi World")     let parameterDictionary = ["username" : "Test", "password" : "123456"]     var request = URLRequest(url: serviceUrl)     request.httpMethod = "POST"     request.setValue("Application/json", forHTTPHeaderField: "Content-Type")     guard let httpBody = try?

Yaah solved it. There was a negligence mistake. I used an additional slash in the URL. I changed the web API to a different folder and I made this mistake while changing it in the iOS code. and Also Set your timeout interval here.

let RequestData = NSMutableURLRequest(URL: NSURL.init(string: "Your URL Hear")!) RequestData.HTTPMethod = "POST" RequestData.timeoutInterval = 250 // Time interval here.  Alamofire.request(RequestData).responseJSON { (responseData) -> Void in     if((responseData.result.value) != nil) { // response         print(responseData.result.value!)     } }     

Hope this Help You..

Alamofire: cache large files downloaded to the Documents folder

I use this piece of code to download MP3 files to the documents directory:

let destination = DownloadRequest.suggestedDownloadDestination(for: .documentDirectory) Alamofire.download(theUrl!, to:destination).response { response in     // stuff }.downloadProgress { progress in     // Stuff } 

The file downloads fine, but if i close the app and start it again, the download restarts from 0. What i want is for the file to be cached and fetched immediatly. My understanding of Alamofire is that the file is downloaded to a temporary folder and then moved to the Documents folder, is this what causes the cache to not happend ?

Thanks a lot

Please check the following references in order:
1. https://github.com/Alamofire/Alamofire/issues/1104
2. https://github.com/Alamofire/Alamofire#resuming-a-download
3. https://stackoverflow.com/a/39347461/3549695

In summary:
You need to use the request.cancel() API to generate the resumeData before your app exit.
Then you use the resume API with the resumeData to resume the request when the app restart.
There is no guarantee that it will always work. If it fails then it will still restart from 0.

There was a mentioning of issue with iOS 10 in reference (2) above that prevent this from working properly. But the update on StackOverflow (ref. 3) has a report that it has been fixed in iOS 10.2

I was able to fix this issue by changing alamofire parameter encoding. By default Alamofire sets encoding to URLEncoding if you are not passing any encoding argument. Use URLEncoding for GET and DELETE request. Use JSONEncoding.default for all other requests (API should have support for this).

Still i'm not sure why it was working w/o socket and wasn't working with socket on.

Resume download after killing or putting on background the application

I have some issues when I want to resume a download operation. I am using Alamofire 4.4 and I made my tests on iOS 9 and 10. Here is my use cases:

1- A download operation is in progress, I cancel the request (resumeData is generated and saved) and then I put the application on background. After relaunching the application, I resume the download (using the resumeData) some times the download is being resumed and sometimes is being restarted. Is it a normal behaviour ? And are there any solution if not ?

2- A download operation is in progress, and i kill the application. Downloaded data seems to be lost and I can't resume the download. Is there any solution to get the resumeData and resume the download after restarting the application ?

Thank you.

How to use a Proxy Server with Alamofire 4 and Swift 3

Please don't mark as duplicate, I haven't been able to solve my Issue with the existing threads.

I'm trying to use my Proxy for an API request that needs a specified IP. To debug my issue, I'm requesting the IP from a webservice.

This is my current code:

import UIKit import Alamofire  class ViewController: UIViewController {      var requestManager = Alamofire.SessionManager.default      override func viewDidLoad() {         super.viewDidLoad()     }      override func viewDidAppear(_ animated: Bool) {         super.viewDidAppear(true)          var proxyConfiguration = [NSObject: AnyObject]()         proxyConfiguration[kCFNetworkProxiesHTTPProxy] = "http://xxx@eu-west-static-01.quotaguard.com" as AnyObject?         proxyConfiguration[kCFNetworkProxiesHTTPPort] = "9293" as AnyObject?         proxyConfiguration[kCFNetworkProxiesHTTPEnable] = 1 as AnyObject?          let cfg = Alamofire.SessionManager.default.session.configuration         cfg.connectionProxyDictionary = proxyConfiguration          let ip = URL(string: "https://api.ipify.org?format=json")          requestManager = Alamofire.SessionManager(configuration: cfg)         requestManager.request(ip!).response { response in             print("Request: \(response.request)")             print("Response: \(response.response)")             print("Error: \(response.error)")              if let data = response.data, let utf8Text = String(data: data, encoding: .utf8) {                 print("Data: \(utf8Text)")             }         }     } } 

The problem: the responsed IP is the same with or without the proxyConfiguration. Any help is very appreciated.

I think the working (supposed to be deprecated) keys are:

kCFStreamPropertyHTTPSProxyHost kCFStreamPropertyHTTPSProxyPort 

Could you try this code?

Also please make sure your proxy server is configured to handle https requests.

Note: It might give deprecated warning for those keys but keys are still working (see https://forums.developer.apple.com/thread/19356#131446)

Note: I posted the same answer here. Posting the same here as it was applicable here as well. Alamofire is using same URLSessionConfiguration.

Alamofire 4 and special characters in JSON

I've got a problem with special characters with Alamofire 4.
The JSON contains æ, ø and å and the browser shows them fine, also my previous solution using SwiftyJSON did.

Alamofire 4 shows something like this instead:

Alamofire.request(specificURL, method: .get, parameters: param, encoding: URLEncoding.default, headers: nil).responseJSON { (response: DataResponse<Any>) in     print(response) }

Swift 3 update for Ekta's answer:

let encodedURL = specificURL.addingPercentEncoding(withAllowedCharacters: NSCharacterSet.urlQueryAllowed) 

Answers 3

Seems the typical serialization error due to wrong JSON encoding, probably your response status code is 3840.

JSON text SHALL be encoded in UTF-8, UTF-16, or UTF-32.

You could try to convert the response data to correct UTF8 encoding:

let datastring = NSString(data: response.data!, encoding: String.Encoding.isoLatin1.rawValue) let data = datastring!.data(using: String.Encoding.utf8.rawValue) do {      let object = try JSONSerialization.jsonObject(with: data!, options: .allowFragments)      let jsonDic = object as! NSDictionary      print("  ok, successfully converted..\(jsonDic)") } catch let aError as Error {      // print and handle aError  } 

Hope it helps you.

Always get build error : No such module 'Alamofire'

I followed the instruction of Alamofire in github,

I created an xcode project named cocoapods-test & I closed it.

I go to the project folder run pod init command which generates a Podfile. Then I added the following code to the Podfile:

source 'https://github.com/CocoaPods/Specs.git' platform :ios, '8.0' use_frameworks!  pod 'Alamofire', '~> 3.0' 

Then, I run command pod install and this is the result in terminal:

Then, in my project folder there is a new file called cocoapods-test.xcworkspace . I double clicked it which opens my xcode again, and I can see the Alamofire module.

Then, I opened my project's ViewController class, and import Alamofire . But no matter how many times I clean & build, I always get error No such module 'Alamofire' . Here is the screenshot:

I was having this exact same problem. Please make sure that you are on Xcode 7.3 and using Swift 2.2.

You can check your Swift version using xcrun swift -version. Updating Xcode to 7.3 should also automatically update Swift.

Updating Xcode resolved this issue for me.

You can try put pod 'Alamofire', '~> 3.0' like below. And run pod install again.

Multiple calls to a Alamofire request, get reference for each call

I have used Alamofire for uploading images in multipart form data. I am successful in achieving my target. Each time I upload an image, I call the "uploadDocWebService" function. So the number of times the function is called, is equal to the number of images. I am hopeless in identifying the result of each call. My images are uploaded successfully. In case there is a server failure, or internet connection failure the uploading fails, I cannot identify which image I should delete from the view, that has failed. I pass indexPath as a parameter for each image upload. But that indexPath updates to the latest image upload before I receive the result for the first image upload. Can any one suggest me a better approach for this situation.

Here is the code I use for image upload:

func uploadDocWebservice(fileUrl: NSURL , progressView : PWProgressView , index : String , imageData : NSData? , name : String , mimeType : String , uploadType : String){      let url = "\(kBaseURL)\(uploadDocsUrl)"      var type = String()     var networkGroupId = String(SingletonClass.sharedInstance.selectedNetworkId!)      if SingletonClass.sharedInstance.groupPopUp == true {          type = "group"         networkGroupId = String(SingletonClass.sharedInstance.selectedSubNetworkOrGroup!)      }else {          type = "network"     }      Alamofire.upload(         .POST,         url,         multipartFormData: { multipartFormData in              if uploadType == "Image" {                 multipartFormData.appendBodyPart( data: imageData! , name: "file", fileName: name, mimeType: mimeType)             }else {                 multipartFormData.appendBodyPart(fileURL: fileUrl, name: "file")             }             multipartFormData.appendBodyPart(data:"\(SingletonClass.sharedInstance.tokenId)".dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)!, name :"token")             multipartFormData.appendBodyPart(data:"\(type)".dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)!, name :"networkGroup")             multipartFormData.appendBodyPart(data:"\(networkGroupId)".dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)!, name :"networkGroupId")          },         encodingCompletion: { encodingResult in             switch encodingResult {             case .Success(let upload, _, _):                  upload.progress { bytesRead, totalBytesRead, totalBytesExpectedToRead in                      let ratio: Float = Float(totalBytesRead) / Float(totalBytesExpectedToRead)                     // Call main thread.                     dispatch_async(dispatch_get_main_queue(), {                         progressView.progress = ratio                     })                  }                  upload.responseJSON { response in                      let dataString = NSString(data: response.data!, encoding:NSUTF8StringEncoding)                     print(dataString)                      self.edited = true                      do{                          let json = try NSJSONSerialization.JSONObjectWithData(response.data!, options: .MutableLeaves) as?

You need to keep a reference to the original request, should be the same for upload requests I think. Try the following:

func uploadDocWebservice(fileUrl: NSURL , progressView : PWProgressView , index : String , imageData : NSData? , name : String , mimeType : String , uploadType : String) -> Request? {     return Alamofire.upload ... } 

Then you can simply have an array of requests i.e: var requests: [Request](). When calling Alamofire.upload / Alamofire .request - it returns a Request object.

You can then do:

var requests: [Request]() let request = uploadDocWebservice(...) requests.append(request) 

Then you can just loop through the array and check whatever request you wish.

Using Alamofire with an iOS 8.0 Embedded Framework

I am trying to use Alamofire within a custom framework that I am creating. I created my custom framework project, added the Podfile, installed Alamofire. I then created a sample project to test out my custom framework.

The sample project is compiling fine with my custom framework import, that is until I started making Alamofire calls within my framework. Now Xcode is complaining about "Missing require module 'Alamofire'" within my sample project. And if I add "import Alamofire" to the swift file, Xcode now complains about "No such module 'Alamofire'"

Is if possible to use a swift framework such as Alamofire within a custom framework, and does the project using my custom framework need to import the Alamofire framework as well?

Yes, it is possible to use Alamofire within your custom framework, but you need to also include Alamofire in the podfile of your sample project (the project that uses your framework). Your podfile should look like this:

platform :ios, '8.0' use_frameworks!  target 'MyApp' do #   pod 'MyFramework'  Include MyFramework if it is a cocoadpod    pod 'Alamofire' end 

The error "Missing required module 'Alamofire'" happens because your framework doesn't actually include Alamofire when you use it in some other project, and you cannot import Alamofire in your sample project for the same reason.

If you plan to make your project a Pod you can include the following line in your podspec:

s.dependency "Alamofire", "~> 3.1.5" 

Including Alamofire as a dependency in the podspec instructs cocoapods to also include it when your framework is installed.

Hope it helps.

Not 100% sure if this is your issue of not, but for swift stuff you have to use the use_frameworks! directive in your Podfile. Could that be the issue?
