使用Alamofire上传具有base64String编码多个图像的数组

我正在努力使用Alamofire发送多个图像到后端。 我有一个NSMutableArray中添加了base64的图像string。 现在我试图发送这个string数组到服务器，但它不工作。

我已经尝试通过这种方式上传一个单一的图像，它超酷，但为什么不是一个图像数组 。

图像挑选 –

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) { if let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage { imageView.contentMode = .ScaleAspectFit imageView.image = pickedImage slctdImage = pickedImage } dismissViewControllerAnimated(true, completion: nil) uploadImage(slctdImage) } 

上传

 func uploadImage( image:UIImage) { let pic :NSData = UIImageJPEGRepresentation(image, 0.5)! let str = pic.base64EncodedStringWithOptions(NSDataBase64EncodingOptions(rawValue: 0)) //imageArray is declared as var imageArray = NSMutableArray() imageArray.addObject(str) //when imageArray count reaches 3 I send the images if imageArray.count==3 { let parameters = [ "task": "doNotification", "image" : imageArray, "select_category" : "exams", "select_type" : "quarterly", "class" : "1", "repliable" : "0", "select_students" : ["25","26"], "select_group" : "Super Users", "title" : "Hello", "text" : "asdfsdf", "date" : "2015-12-15", "time" : "10:50 AM"] Alamofire.request(.POST, UrlClass.baseUrl, parameters:parameters ) .response { (request, response, data, error) in // self.startParsing(data!) print(response) } } } 

那么如何解决这个问题？ 请build议修改代码或其他方式。

使用以下代码将图像上传到服务器

  let image = UIImage(named:"testImage") Alamofire.upload( .POST, URL, multipartFormData: { multipartFormData in multipartFormData.appendBodyPart(data: UIImageJPEGRepresentation(image, 1)!, name: "imageFile", fileName: "image.jpg", mimeType: "image/jpeg") }, encodingCompletion: { encodingResult in switch encodingResult { case .Success(let upload, _, _): upload.progress { bytesWritten, totalBytesWritten, totalBytesExpectedToWrite in dispatch_async(dispatch_get_main_queue()) { let percent = (Float(totalBytesWritten) / Float(totalBytesExpectedToWrite)) //progress(percent: percent) print(percent) } } upload.validate() upload.responseJSON { response in if response.result.error != nil { // failure } else { // success } } case .Failure(let encodingError): print(encodingError) //failure } } ) } 

对于多个图像

 Alamofire.upload( .POST, urlString, multipartFormData: { multipartFormData in multipartFormData.appendBodyPart(data: "122222".dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)!, name :"Id") multipartFormData.appendBodyPart(data: "test1111".dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)!, name :"sId") multipartFormData.appendBodyPart(data: "", name :"ContractorIds") multipartFormData.appendBodyPart(data:date.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)!, name :"ExpectedOn") multipartFormData.appendBodyPart(data:date.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)!, name :"ExpiresOn") multipartFormData.appendBodyPart(data: data.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)!, name :"Notes") for image in images { if let imageData = UIImageJPEGRepresentation(image, 0.05) { multipartFormData.appendBodyPart(data: imageData, name: "file", fileName: "file.jpeg", mimeType: "image/jpeg") } } },

这里是另一个版本，因为我在服务器端面对读取多个图像的问题：

 Alamofire.upload(multipartFormData: { (multipartFormData) in // Sending parametes with images multipartFormData.append(jsonString.data(using: String.Encoding.utf8)!, withName: "parameters") for (key, value) in parameters { if let files = value as? Array<Any>, key == "files" { for i in files.enumerated() { let image = UIImage(named: "\(i.element)") // add image multipartFormData.append(UIImageJPEGRepresentation(image!, 1)!, withName: "file" , fileName: "\( NSUUID().uuidString)" , mimeType: "image/jpeg") // if you face problem add below lines as to make sepration between two images multipartFormData.append("\r\r".data(using: String.Encoding.utf8)!, withName: "") } } else { } } },to:baseURL)
