通过Swift 3和Alamofire 4上传带有JSON和自定义标题的照片文件iOS |迅速

概述我需要使用 Image文件和 JSON调用Multipart请求. 我试过这个,但仍然得到错误. // define parameters let parameters = [ "hometown": "yalikavak", "living": "istanbul" ]Alamofire.upload(multipartFormData: { multipartFor 我需要使用 Image文件和 JSON调用Multipart请求.

我试过这个,但仍然得到错误.

// 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？

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.

// 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])         }    }
