如何使用带有标记和参数的Alamofire来上传图片？

我使用Alamofire来上传图片，但上传不成功。
我也把令牌和参数带到服务器上。
我不知道我是否正确添加标记和参数。
我使用Alamofire有什么问题？
有什么build议吗？ 谢谢。

func uploadWithAlamofire(image:UIImage, imageData:Data, imageUrl:URL) { let parameters = ["avatar":imageData] Alamofire.upload(multipartFormData: { multipartFormData in multipartFormData.append(imageData, withName: user.id, fileName: "\(user.id).jpg", mimeType: "image/jpg") for (key, value) in parameters { multipartFormData.append(value, withName: key) } }, to: apiUrl , method: .put, headers: ["Authorization": "Bearer \(token)"], encodingCompletion: { encodingResult in switch encodingResult { case .success(let upload, _, _): upload.response { [weak self] response in guard self != nil else { return } debugPrint(response) } case .failure(let encodingError): print("error:\(encodingError)") } }) } func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) { photoImage = info[UIImagePickerControllerOriginalImage] as! UIImage photoImageView.image = photoImage let imageName:String = user.id + ".jpg" let documentsPath = NSHomeDirectory().appending("/Documents/Icon/") let imagePath = documentsPath.appending(imageName) let imageUrl = URL(fileURLWithPath: imagePath) print("imageUrl is here:\(imageUrl)") let imageData:Data = UIImageJPEGRepresentation(photoImage, 0.001)! do { try imageData.write(to: imageUrl,options: .atomic) } catch let error { print(error) } uploadWithAlamofire(image: photoImage, imageData: imageData, imageUrl: imageUrl) self.dismiss(animated: true, completion: nil) }

尝试这个：

 func uploadImageWith(param params:Dictionary<String,String>,image:UIImage?,handler:@escaping ((Dictionary<String,Any>?,Int) -> Void)) { // let keyJson = "json".dataUsingEncoding(NSUTF8StringEncoding)! print("Params:\(params)") let BASE_URL = "http://" Alamofire.upload( multipartFormData: { multipartFormData in for (key, value) in params { multipartFormData.append(value.data(using: String.Encoding.utf8, allowLossyConversion: false)!, withName: key) } if image != nil{ let imgData = UIImageJPEGRepresentation(image!, 0.5) if imgData != nil { multipartFormData.append(imgData!, withName: "photo_upload", fileName: "file.png", mimeType: "image/png") } } }, to: BASE_URL, encodingCompletion: { encodingResult in switch encodingResult { case .success(let upload, _, _): upload.responseJSON { response in switch response.result { case .success: if let jsonDict = response.result.value as? Dictionary<String,Any> { print_debug("Json Response: \(jsonDict)") // serialized json response handler(jsonDict,(response.response!.statusCode)) } else{ handler(nil,(response.response!.statusCode)) } if let data = response.data, let utf8Text = String(data: data, encoding: .utf8) { print("Server Response: \(utf8Text)") // original server data as UTF8 string } break case .failure(let error): handler(nil,(response.response!.statusCode)) break } } case .failure(let encodingError): print(encodingError) } } ) } 

使用

 uploadImageWith(param: ["key":"value"], image: UIImage(name:"icon")) { (response, statusCode) in print(response) } 

你必须传递参数和图像对象，并在闭包中获得作为Dictionary对象的响应。

使用此function可以使用令牌和参数将图像上传到服务器

 func uploadImageAndData(){ var parameters = [String:AnyObject]() parameters = ["token": token, "Name": Name] 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) } })} 

适用于Alamofire 3.0+
