我用其他一些参数上传图像，我编写了这段代码，但是在这段代码中无法成功，我在解决此问题时遇到了一些错误
还更改参数类型（NSDictionary和字符串类型）和Alamofire更新窗格。
我面对这行错误
multipartFormData.append(value.data(using: String.Encoding.utf8)!,
withName: key)
错误是
“任何”类型的值没有成员“数据”
代码听见了
let parameter : NSDictionary = ["auth_key": UserDefaults.standard.value(forKey: GlobalConstants.kAuthKey)!,
"userid" : UserDefaults.standard.value(forKey: GlobalConstants.kuserId)!,
"eventname" : self.txtEventName.text!,
"eventdescription" : self.textviewDescription.text!,
"event_categories" : self.arrSelectEventID,
"eventshop" : self.selectedOrganizerID,
"eventreef" : self.selectedReefID,
"event_start_date_time" : self.Startdate,
"event_start_time" : self.startTime,
"event_end_date_time" : self.Enddate,
"event_end_time" : self.EnfTime,
"meeting_location" : self.MeetingPoint,
"meeting_location_address" : meetingAddress,
"meeting_location_latitude" : meetinglat,
"meeting_location_longitude" : meetingLong,
"event_ticket_price" : self.txtEventTicketPrice.text! ,
"event_ticket_qty" : self.txtEventTicketQuantity.text!,
"eventvideourl" : self.txtVideoURL.text!,
"recurrence_type" : "none" ,
"end" : self.End,
"end_type" : self.EndType,
"end-count" : self.EndCount,
"create_ticket_on_event" : ""]
let image = self.imgCover.image
let imageData = image?.jpegData(compressionQuality: 1)
Alamofire.upload(multipartFormData: { multipartFormData in
// import image to request
multipartFormData.append(imageData!, withName: "eventimage", fileName: "profile.jpg", mimeType: "image/jpeg")
for (key, value) in parameter {
multipartFormData.append(value.data(using: String.Encoding.utf8)!, withName: key)
}
}, to: strURL,
encodingCompletion: { encodingResult in
switch encodingResult {
case .success(let upload, _, _):
upload.responseJSON { response in
}
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)")
var dic = response.result.value as? [String: Any]
let alert = UIAlertController(title: "Alert", message: dic!["message"] as? String , preferredStyle: .alert)
self.present(alert, animated: true)
alert.addAction(UIAlertAction(title: "OK", style: .default, handler: { action in
}))
}
}
case .failure(let error):
print(error)
}
})`
