How to upload multiple images in a array under a same key name in swift 4 without using Alamofire

Question

Checkout the code for single image upload but not able to upload the multiple images in an array under same key.

IN BELOW CODE , It is working perfect when I am sending one image to the server. -> I want to find answer for the multiple images in array without using alamofire or other third party library.

      func imageUploadRequest(IMAGE_ARRAY: [UIImage] , uploadUrl: NSURL) {

        myloader.showLoader(controller: self)
      let param = ["title":"ds","category_id":"5","description":"gdfjghjdsfgksd","user_id":"66","color":"red"]

        let request = NSMutableURLRequest(url:uploadUrl as URL)
        request.httpMethod = "POST"
        let boundary = generateBoundaryString()
        request.setValue("multipart/form-data; boundary=\(boundary)", forHTTPHeaderField: "Content-Type")

        //let imageData = UIImageJPEGRepresentation(imageView.imageOrientation, 0.1)
        for item in IMAGE_ARRAY
        {
            let imageData = item.jpegData(compressionQuality: 0.01)
            if(imageData==nil)  { return; }

            request.httpBody = createBodyWithParameters(parameters: param as [String : Any], filePathKey: "files[]", cv : imageData! as NSData, boundary: boundary) as Data
        }

        // myActivityIndicator.startAnimating();

        let task =  URLSession.shared.dataTask(with: request as URLRequest,
                                               completionHandler: {
                                                (data, response, error) -> Void in
                                                if let data = data {
                                                    DispatchQueue.main.async { // Update UI
                                                        self.myloader.removeLoader(controller: self)
                                                        let decoder = JSONDecoder()

                                                        let obj = try! decoder.decode(GetResponse_Otp.self, from: data)


                                                    }
                                                }
        })
        task.resume()
    }

    func createBodyWithParameters(parameters: [String: Any]?, filePathKey: String?, cv: NSData, boundary: String) -> NSData {
        let body = NSMutableData();

        if parameters != nil {
            for (key, value) in parameters! {
                body.appendString("--\(boundary)\r\n")
                body.appendString("Content-Disposition: form-data; name=\"\(key)\"\r\n\r\n")
                body.appendString("\(value)\r\n")
            }
        }

        let filename = "\(Date().timeIntervalSince1970).jpeg"
        let mimetype = "image/png"

        body.appendString("--\(boundary)\r\n")
        body.appendString("Content-Disposition: form-data; name=\"\(filePathKey!)\"; filename=\"\(filename)\"\r\n")
        body.appendString("Content-Type: \(mimetype)\r\n\r\n")
        body.append(cv as Data)
        body.appendString("\r\n")

        body.appendString("--\(boundary)--\r\n")

        return body
    }

    func generateBoundaryString() -> String {
        return "Boundary-\(NSUUID().uuidString)"
    }
    // extension for impage uploading
}

You need to change your key name to KEY_NAME[] add array [] in your key and make sure every time the file name is different or you can try this too:

(Date().timeIntervalSince1970).jpeg

to make sure that the name is different everytime.

according to your answer , all the images will set on different key . how can we send image array in same key – Ankur Purwar Nov 07 '19 at 05:22
No key will be same like IMAGE_KEY[] but image name is different everytime. – Munzareen Atique Nov 07 '19 at 07:56

Check i edit the code in caps.

Change this `let filename = "\(Date().timeIntervalSince1970).jpeg"` to your specific images name which should be different and change the mimeType to `mimeType: "image/jpeg"` — Munzareen Atique, Nov 07 '19 at 10:35
Brother It clearly shows that issue regarding json and if you want api the I will let you know — Ankur Purwar, Nov 07 '19 at 11:08
Brother only on image is uploading on the server , tell me your what's app , I will share. a api and other details — Ankur Purwar, Nov 08 '19 at 05:52
