使用Swift将照片上传到网络服务

Question

我想上传照片。我检查了Alamofire，但是所有的例子都是用Json编码的。我需要上传用app拍摄的照片并将其作为文件发送到webservice。 Web服务的响应也是字符串。我该怎么做？

Alamofire.upload(.POST, urlString, multipartFormData: {
        multipartFormData in
        if let _image = self.profilePic.image {
            if let imageData = UIImagePNGRepresentation(_image) {
                multipartFormData.appendBodyPart(data: imageData, name: "user_image", fileName: "file.png", mimeType: "image/png")
            }
        }
        for (key, value) in userInfo {
            multipartFormData.appendBodyPart(data: value.dataUsingEncoding(NSUTF8StringEncoding)!, name: key)
        }
        }, encodingCompletion: { encodingResult in
            switch encodingResult {
            case .Success(let upload, _, _):
                upload.responseJSON { response in
                    debugPrint(response)
                }
            case .Failure(let encodingError):
                print(encodingError)
            }
        }
    )

self.profilePic.image是你的形象。
