【问题描述】：

如果您正在处理具有不同键的多个图像并且还具有具有不同类型键值对的参数字典，例如“String”：“Any”，“String”：“[Any]”，如何快速处理多部分, [[String:Any]].

let headers: HTTPHeaders = ["Content-type": "multipart/form-data"]

    Alamofire.upload(multipartFormData:  (multipartFormData) in

        for (key, value) in parameters 
            multipartFormData.append("\(value)".data(using: String.Encoding.utf8)!, withName: key as String)
        

        //Todo: - Images
        var c = 0
        for dictImage in arrImage 

            let validDict = kSharedInstance.getDictionary(dictImage)

            for keyName in validDict.keys 
                print(keyName)

                //Incr
                c += 1

                if let imageData = validDict[keyName] as? Data 

                    multipartFormData.append(imageData, withName: "\(keyName)", fileName: "\(Date().timeIntervalSince1970).jpeg", mimeType: "image/jpeg")

                

            
        


    , usingThreshold: UInt64(), to: urlString, method: .post, headers: headers)  (result) in
        switch result
        case .success(let upload, _, _):
            upload.responseJSON  response in
                print("Succesfully uploaded")

                if((response.result.value) != nil) 
                    debugPrint(response.result.value!)

                    let jsonData = JSON(response.result.value!)
                    if jsonData["status"].bool == true 
                        completion(jsonData.dictionaryObject!, true)
                    else
                    
                        completion(jsonData.dictionaryObject!, false)
                    
                
            
        case .failure(let error):
            print("Error in upload: \(error.localizedDescription)")
            failure(error, false)
        
    

【问题讨论】：

它只上传简单的（键，值）对。但是，无法上传图片和其余数据。

【参考方案1】：

请检查以下代码。希望对你有帮助

  Alamofire.upload(
        multipartFormData:  MultipartFormData in
        for (key, value) in parameters 
            MultipartFormData.append(value.data(using: String.Encoding.utf8)!, withName: key)
        

        for i in 0 ..< files.count 
            let fileName : String  = "image\(i).jpg"
            let datum : Data = files[i]
            MultipartFormData.append(datum, withName: fileParamName, fileName: fileName, mimeType: "image/jpg")
        

    , to: URLString, method: .post, headers: headers)  (result) in
        switch(result) 

        case .success(let upload, _, _):
            upload.responseJSON  response in

            
            break;
        case .failure(_):
