Uploading Image to API Server using Alamofire - swift

Question

I have a question about Uploading Image to API server using Alamofire.
BaseURL: http://vietnamtravelguide-app.com/quangnam/api_inquangnam/tips/create?user_id=""&token=""
3 parameters : location_id, content, imageName
It's ok to post by POSTMAN
My Code:
Alamofire.upload(multipartFormData: { multipartFormData in
multipartFormData.append(image, withName: "imageName", fileName: "swift_file.jpeg", mimeType: "image/jpeg")
}, with: path, encodingCompletion: {encodingResult in
switch encodingResult {
case .success(let upload, _, _):
upload.responseJSON { response in
print(response.result)
switch response.result {
case .success:
let json = JSON(response.result.value!)
if(delegate != nil) {
delegate!.didReceiveResult(json,basePath: basePath)
}
case .failure(let error):
print(error)
} }
case .failure(let encodingError):
print(encodingError)
}
})
with image ( image from parameter casting as Data). When I debug it , i got response.result return failure

You are not uploading the remaining two parameters content and location_id.
Try this one and see the result. I have also used SwiftyJSON here.
This is my APIManager class for all APIs handling.
import Alamofire
import SwiftyJSON
class APIManager: NSObject {
class func apiMultipart(serviceName:String,parameters: [String:Any]?, completionHandler: #escaping (JSON?, NSError?) -> ()) {
Alamofire.upload(multipartFormData: { (multipartFormData:MultipartFormData) in
for (key, value) in parameters! {
if key == "imageName" {
multipartFormData.append(
value as! Data,
withName: key,
fileName: "swift_file.jpg",
mimeType: "image/jpg"
)
} else {
//Data other than image
multipartFormData.append((value as! String).data(using: .utf8)!, withName: key)
}
}
}, usingThreshold: 1, to: serviceName, method: .post, headers: ["yourHeaderKey":"yourHeaderValue"]) { (encodingResult:SessionManager.MultipartFormDataEncodingResult) in
switch encodingResult {
case .success(let upload, _, _):
upload.responseJSON { response in
if response.result.error != nil {
completionHandler(nil,response.result.error as NSError?)
return
}
print(response.result.value!)
if let data = response.result.value {
let json = JSON(data)
completionHandler(json,nil)
}
}
break
case .failure(let encodingError):
print(encodingError)
completionHandler(nil,encodingError as NSError?)
break
}
}
}
}
If you don't have any header then you can leave the field as ["":""] in place of your ["yourHeaderKey":"yourHeaderValue"]
Now in order to call I just formed the parameters in the controller.
var params = [String:AnyObject]()
params["content"] = "something" as AnyObject?
params["location_id"] = "201" as AnyObject?
// Grab your image from some variable or imageView. Here self.profileImage is a UIImage object
if let profileImageData = self.profileImage {
if let imageData = UIImageJPEGRepresentation(profileImageData, 0.5) {
params["imageName"] = imageData as AnyObject?
APIManager.apiMultipart(serviceName: "http://yourAPIURL", parameters: params, completionHandler: { (response:JSON?, error:NSError?) in
//Handle response
})
} else {
print("Image problem")
}
}
