我正在尝试将文件夹名、文件名和扩展名作为参数的图像上传到服务器。我已经做了一些代码，但它给了我一个零的响应。有人能帮我解决吗？有时上传图片，有时不上传。当上传图像失败时，会给出一个"零"响应，并向服务器发送一些垃圾值。这是我的图像上传方法：
func UPLOD(){
let image = myImageView.image!
let serviceName = "http://192.168.80.21:8800/api/v1/upload/uploadfile"
var parameters = [String: AnyObject]()
parameters["Folder"] = "uploadfile" as AnyObject?
parameters["Filename"] = "demo(self.currentTimeStamp)" as AnyObject?
parameters["Ext"] = "jpg" as AnyObject?
parameters["FileToUpload"] = image.jpegData(compressionQuality: 0.5) as AnyObject?
guard let token = UserDefaults.standard.string(forKey: "accesstoken") else {
return
}
print("Create button ACCESS KEY::::- (token)")
let headers: HTTPHeaders = [
"x-access-token": token
]
Alamofire.upload(multipartFormData: { (multipartFormData:MultipartFormData) in
for (key, value) in parameters {
if key == "FileToUpload" {
multipartFormData.append(
value as! Data,
withName: key,
fileName: "demo(self.currentTimeStamp)",
mimeType: "image/jpg"
//_img.jpg
)
} else {
//Data other than image
multipartFormData.append((value as! String).data(using: .utf8)!, withName: key)
}}},
to: serviceName, method: .post, headers: headers) { (encodingResult:SessionManager.MultipartFormDataEncodingResult) in
switch encodingResult {
case .success(let upload, _, _):
upload.responseJSON { response in
//print response.result
print(response.result.value as Any)
}
upload.responseJSON { [self] response in
if let Response = response.result.value as? [String : Any],
let myData = Response["data"] as? [String : Any],
let imgPath = myData["ImagePath"] {
imageUrl = imgPath as! String
print(imageUrl)
print("ImagePath --> ", imgPath)
responseURL = imageUrl
let defaults = UserDefaults.standard
defaults.setValue(imageUrl, forKey: "imageURL")
let key = defaults.object(forKey: "imageURL")
print(key as Any)
self.alamofireRequest(requestURL: "http://192.168.80.21:3204/api/product/create")
}
if let data = response.result.value {
let _ = JSON(data)
}
}
break
case .failure(let encodingError):
print(encodingError)
break
}
}
}
