$ b中显示错误$ b

AF.upload（multipartFormData：{ MultipartFormData方法行

AF.upload(multipartFormData: { MultipartFormData line of method

（注意：Alamofire 5.0更新后，Alamofire.upload更改为AF.upload）

(Note : Alamofire.upload is change to AF.upload After Alamofire 5.0 Update)

@IBAction func btnUploadImage(_ sender: UIButton) { let uploadDict = ["user_id":getUserId] as [String:String] AF.upload(multipartFormData: { MultipartFormData in let image :Data = UIImageJPEGRepresentation(self.uploadImg.image!, 1.0)! MultipartFormData.append(image, withName: "image" , fileName: "image.jpeg" , mimeType: "image/jpeg") for(key,value) in uploadDict{ MultipartFormData.append(value.data(using: String.Encoding.utf8)!, withName: key)} }, to: "XXXXXXXXXXXXXXXX/uploadImage", encodingCompletion: { EncodingResult in switch EncodingResult{ case .success(let upload, _, _): upload.responseJSON { response in debugPrint("SUCCESS RESPONSE: \(response)") } case .failure(let encodingError): print("ERROR RESPONSE: \(encodingError)") } })

//此代码的查看控制器

}

推荐答案

我刚刚用

pod 'Alamofire', '~> 5.0.0-beta.5'

//示例代码

let image: UIImage? = self.uploadImg.image; let uploadDict = ["user_id":getUserId] as [String:String] Alamofire.upload(multipartFormData: { MultipartFormData in let image :Data = (image?.jpegData(compressionQuality: 1))! MultipartFormData.append(image, withName: "image" , fileName: "image.jpeg" , mimeType: "image/jpeg") for(key,value) in uploadDict{ MultipartFormData.append(value.data(using: String.Encoding.utf8)!, withName: key)} }, to: "XXXXXXXXXXXXXXXX/uploadImage", encodingCompletion: { EncodingResult in switch EncodingResult{ case .success(let upload, _, _): upload.responseJSON { response in debugPrint("SUCCESS RESPONSE: \(response)") } case .failure(let encodingError): print("ERROR RESPONSE: \(encodingError)") } })
