Image uploading with parameters using Alamofire in Swift - ios

Question

I am using Alamofire for my data post to the server. I ahve an image which I want to upload to server in Data form with some other parameters. In Alamofire, I am using multipartFormData method to post all the parameters and image. Server needs data to be in JSON format with parameters which is shown below:
{"product_name": "almondsfdsfsdf",
"product_price": "400",
"product_img": image.jpg}
I am trying but it gives me a failure in response. Here is my code of what I am doing in swift with alamofire:
let productName = itemNameTF.text!
let productPrice = itemPriceTF.text!
let productImage:UIImage = itemImage.image!
let url = "URL"
let parameter = ["product_name": productName, "product_price": productPrice]
let headers : HTTPHeaders = ["Content-Type": "application/json","Authorization" : "Token abcd"]
Alamofire.upload(multipartFormData: {
multipartFormData in
if let imageData = UIImageJPEGRepresentation(productImage, 0.5){
multipartFormData.append(imageData, withName: "image", fileName: "file.png", mimeType: "image/png")
}
for (key,value) in parameter {
multipartFormData.append(value.data(using: .utf8)!, withName: key)
}
}, to: url,method: .post, headers: headers, encodingCompletion: { encodingResult in
switch encodingResult {
case .success(let upload,_,_):
upload.responseJSON { response in
print(response.request)
print(response.response)
print(response.result)
print(response.data)
}
break
case .failure(let encodingError):
print("error: \(encodingError)")
break
}
})
My server accept image in BLOB data. If anyone could help me. Thank you!

Answer 1

Try to change this line:
multipartFormData.append(imageData, withName: "image", fileName: "file.png", mimeType: "image/png")
To this:
multipartFormData.append(imageData, withName: "product_img", fileName: "image.jpg", mimeType: "image/jpeg")

Please take reference from below method to get the answer(Works for the Alamofire 3.0+).
func uploadImageAndData(){
var parameters = [String:AnyObject]()
parameters = ["token":token,
"lastName":lastName]
let URL = "http://yourserviceurl/"
let image = UIImage(named: "image.png")
Alamofire.upload(.POST, URL, multipartFormData: {
multipartFormData in
if let imageData = UIImageJPEGRepresentation(image, 0.6) {
multipartFormData.appendBodyPart(data: imageData, name: "image", fileName: "file.png", mimeType: "image/png")
}
for (key, value) in parameters {
multipartFormData.appendBodyPart(data: value.dataUsingEncoding(NSUTF8StringEncoding)!, name: key)
}
}, encodingCompletion: {
encodingResult in
switch encodingResult {
case .Success(let upload, _, _):
print("s")
upload.responseJSON {
response in
print(response.request) // original URL request
print(response.response) // URL response
print(response.data) // server data
print(response.result) // result of response serialization
if let JSON = response.result.value {
print("JSON: \(JSON)")
}
}
case .Failure(let encodingError):
print(encodingError)
}
})
}
