Question

我正在尝试在服务器上进行视频上传。我正在使用Alamofire。我正在接近一个解决方案，但是...我有一个多部分数据表单方法，其中包含这样的参数“param1”：“test”，“param2”：[“1”，“2”]，param3：{“测试“：”123“}

param1仍然放置一个函数Alamofire.upload：

multipartFormData.appendBodyPart (date "test" .dataUsingEncoding (NSUTF8StringEncoding, allowLossyConversion: false) !, name: "param1")

如何添加param2和param3？

有我的方法：

    Alamofire.upload(
                .POST,
                url,
                headers: headers,
                multipartFormData: { multipartFormData in

                    multipartFormData.appendBodyPart(data: "test".dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)!, name :"param1")

//it is only visualization what I want to do. I know that it isn't working.
                    //multipartFormData.appendBodyPart(data: ["1", "2"].dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)!, name :"param2")
                    //multipartFormData.appendBodyPart(data: {"test": "123 "}.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)!, name :"param3")

                    let fileURL = DataManager().getFileDirectionForFile("movie.mp4")
                    multipartFormData.appendBodyPart(fileURL: fileURL, name: "file")
                },
                encodingCompletion: { encodingResult in
                    switch encodingResult {

                    case .Success(let upload, _, _):
                        upload.responseString { response in
                            debugPrint(response)
                        }

                    case .Failure(let encodingError):
                        print(encodingError)
                    }
                }

首先创建param dict以传入请求。

let array = ["1","2"]
let dict = [
    "test" : "123"
]

let params = [
    "param1" : "test",
    "param2" : array,
    "param3" : dict
]

然后将该params变量传递给Alamofire.upload

Alamofire.upload(.POST, url, multipartFormData: { (multipartFormData) in
        multipartFormData.appendBodyPart(data: params["param1"]!.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)!, name: "param1")
        multipartFormData.appendBodyPart(data: params["param2"]!.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)!, name: "param2")
        multipartFormData.appendBodyPart(data: params["param3"]!.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)!, name: "param3")
        }) { (encodingResult) in
            switch encodingResult {

            case .Success(let upload, _, _):
                upload.responseString { response in
                    debugPrint(response)
                }

            case .Failure(let encodingError):
                print(encodingError)
            }
    }

这取决于您的API。我的API在相同的情况下可以处理这种格式：

multipartFormData.appendBodyPart(data: "1".dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)!, name :"param2[0]")
multipartFormData.appendBodyPart(data: "2".dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)!, name :"param2[1]")
multipartFormData.appendBodyPart(data: "123 ".dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)!, name :"param3[test]")

也许也适合你。
