我需要使用Image文件和JSON调用Multipart请求。

I need to call the Multipart request with Image file and JSON.

我试过这个，但仍然收到错误。

I have tried this, but still getting the error.

// define parameters let parameters = [ "hometown": "yalikavak", "living": "istanbul" ] Alamofire.upload(multipartFormData: { multipartFormData in if let imageData = UIImageJPEGRepresentation(image, 1) { multipartFormData.append(imageData, withName: "file", fileName: "file.png", mimeType: "image/png") } for (key, value) in parameters { multipartFormData.append((value?.data(using: .utf8))!, withName: key) }}, to: "upload_url", method: .post, headers: ["Authorization": "auth_token"], encodingCompletion: { encodingResult in switch encodingResult { case .success(let upload, _, _): upload.response { [weak self] response in guard let strongSelf = self else { return } debugPrint(response) } case .failure(let encodingError): print("error:\(encodingError)") } }) }

如何发送JSON？

推荐答案

在单个请求中尝试使用此代码进行多个上传图像，此代码已经可用。

Try This Code for Multiple upload Images in Single Request, This code is already working.

// For Pass Valid Parameters & number of Images in Array in Image Upload Function var dicImgData : NSMutableDictionary? = NSMutableDictionary() if let img = UIImage(named: "Your Image") { if let data:Data = UIImagePNGRepresentation(img) { var imageData : NSData = data dicImgData! .setObject(imageData, forKey: "data" as NSCopying) dicImgData! .setObject("file", forKey: "name" as NSCopying) dicImgData! .setObject("file.png", forKey: "fileName" as NSCopying) dicImgData! .setObject("image/png", forKey: "type" as NSCopying) let dicParameter = [ "hometown": "yalikavak", "living": "istanbul" ] self.uploadImage(url: "Your URL", Parameter: dicParameter, Images: [dicImgData]) } }

上传功能

func uploadImage (url: String, Parameter param : NSDictionary, Images arrImage: NSArray) -> Void { var requestURL : String! = url let headers = [ "Authorization": "Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ==", "Accept": "application/json", ] print("---------------------") print("Request URL :- \(requestURL)") print("---------------------") Alamofire.upload(multipartFormData: { (data) in for (key, value) in param { data.append((value as! String).data(using: .utf8)!, withName: key as! String) } for imageInfo in arrImage { var dicInfo : NSDictionary! = imageInfo as! NSDictionary data.append(dicInfo["data"] as! Data, withName: dicInfo["name"] as! String, fileName: dicInfo["fileName"] as! String, mimeType: dicInfo["type"] as! String) dicInfo = nil } }, to: requestURL, method: .post , headers:nil, encodingCompletion: { (encodeResult) in switch encodeResult { case .success(let upload, _, _): upload.responseJSON(completionHandler: { (response) in switch response.result { case .success(let responseJSON): guard let dicResponse = responseJSON as? NSDictionary else{ return } print("Response : \((dicResponse))") case .failure(let error): print(error) break } }) case .failure(let error): print(error) break } }) }
