Multipart Image Alamofire 4 swift 3 -


i've big problem when try update image db.

i must upload image, , string value.

func imagepickercontroller(_ picker: uiimagepickercontroller, didfinishpickingmediawithinfo info: [string : any]) {         if let selectedimage = info[uiimagepickercontrolleroriginalimage] as? uiimage {             imagecropped = selectedimage             self.sendimagewithmultipart()             imagepicker.dismiss(animated: true, completion: { _ in })         }     }  func sendimagewithmultipart() {                 alamofire.upload(multipartformdata: {             multipartformdata in             multipartformdata.append("\(hgygjihf746fg743g)".data(using: string.encoding.utf8, allowlossyconversion: false)!, withname :"auth_token")             multipartformdata.append("\(0)".data(using: string.encoding.utf8, allowlossyconversion: false)!, withname :"os")             multipartformdata.append("\(10.0.3)".data(using: string.encoding.utf8, allowlossyconversion: false)!, withname :"os_version")             multipartformdata.append("\(3.0.3)".data(using: string.encoding.utf8, allowlossyconversion: false)!, withname :"app_version")              if let photo = self.imagecropped, let jpegimage = uiimagejpegrepresentation(photo, 50.0) {                 print(jpegimage)                 multipartformdata.append(jpegimage, withname: "profile_photo", mimetype: "image/*")             }         }, to: "\(constants.general_address_2)\(constants.api_modifyuser_profile_photo)", method:.post, headers:["content-type":"multipart/form-data; charset=utf-8; boundary=__x_paw_boundary__"], encodingcompletion: {             encodingresult in             switch encodingresult {             case .success(request: let upload, streamingfromdisk: _, streamfileurl: _):                 upload.validate().responsejson {                     response in                     if response.result.isfailure {                         debugprint(response)                     } else {                         debugprint(response)                     }                 }             case .failure(let encodingerror):                 nslog((encodingerror nserror).localizeddescription)             }         })     }

but result this:

[request]: "\(constants.general_address_2)\(constants.api_modifyuser_profile_photo)" [response]: <nshttpurlresponse: 0x17023c0e0> { url: "\(constants.general_address_2)\(constants.api_modifyuser_profile_photo)" } { status code: 500, headers {     "cache-control" = "no-cache, private";     connection = close;     "content-length" = 5545;     "content-type" = "text/html; charset=utf-8";     date = "thu, 10 nov 2016 10:49:00 gmt";     server = "apache/2.4.18 (amazon) openssl/1.0.1k-fips php/5.6.21";     "x-powered-by" = "php/5.6.21"; } } [data]: 5545 bytes [result]: failure: responsevalidationfailed(alamofire.aferror.responsevalidationfailurereason.unacceptablestatuscode(500)) [timeline]: timeline: { "request start time": 500467740.667, "initial response time": 500467740.793, "request completed time": 500467743.733, "serialization completed time": 500467743.733, "latency": 0.126 secs, "request duration": 3.066 secs, "serialization duration": 0.000 secs, "total duration": 3.066 secs

the problem how convert image, or content type or what?

thank you

this may potentially resolve issue:

let endpoint = "https://api.blah/images/" + id + "/documents"  let imagedata = uiimagepngrepresentation(image)  alamofire.upload(             multipartformdata: { multipartformdata in                 multipartformdata.append(type.data(using: string.encoding.utf8, allowlossyconversion: false)!, withname :"type")                 multipartformdata.append(imagedata!, withname: "file.png", mimetype: "image/png")         }, to: endpoint, method:.post, headers:headers, encodingcompletion: { encodingresult in             switch encodingresult {             case .success(request: let upload, streamingfromdisk: _, streamfileurl: _):                 upload.validate().responsejson { (response) in                     if response.result.isfailure {                         debugprint(response)                     } else {                         debugprint(response)                     }                 }             case .failure(let encodingerror):                 nslog((encodingerror nserror).localizeddescription)             }         })

seems reach server, in case, 400 (probably failing tv4 validation).
