在iOS Swift中使用Alamofire,使用MultipartFormData发送POST参数

我第一次使用Alamofire。我正在使用最新版本的Alamofire 1.3.1。我想在一个API调用中发送一个图像,一个视频和一些POST参数。我正在使用多部分表单数据。 mutipart模块正在工作。我正在面临一个问题来发送额外的POST参数参数。以下是我的代码“params”是包含额外参数的字典?如何在请求中附加这些POST参数。请帮忙

        var fullUrl :String = Constants.BASE_URL + "/api/CompleteChallenge"
         var params = [
        "authKey": Constants.AuthKey,
        "idUserChallenge": "16",
        "comment": "",
        "photo": imagePath,
        "video": videoPath,
        "latitude": "1",
        "longitude": "1",
        "location": "india"
    ]

    let imagePathUrl = NSURL(fileURLWithPath: imagePath!)
    let videoPathUrl = NSURL(fileURLWithPath: videoPath!)

        Alamofire.upload(
        .POST,
        URLString: fullUrl, // http://httpbin.org/post
        multipartFormData: { multipartFormData in
            multipartFormData.appendBodyPart(fileURL: imagePathUrl!, name: "photo")
            multipartFormData.appendBodyPart(fileURL: videoPathUrl!, name: "video")
        },
        encodingCompletion: { encodingResult in
            switch encodingResult {
            case .Success(let upload, _, _):
                upload.responseJSON { request, response, JSON, error in

                  }
                }
            case .Failure(let encodingError):

            }
        }
    )
最佳答案
我找到解决方案:)最后。

我们可以在请求中附加数据作为multipartformdata。

以下是我的代码

  Alamofire.upload(
        .POST,
        URLString: fullUrl, // http://httpbin.org/post
        multipartFormData: { multipartFormData in
            multipartFormData.appendBodyPart(fileURL: imagePathUrl!, name: "photo")
            multipartFormData.appendBodyPart(fileURL: videoPathUrl!, name: "video")
            multipartFormData.appendBodyPart(data: Constants.AuthKey.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)!, name :"authKey")
            multipartFormData.appendBodyPart(data: "\(16)".dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)!, name :"idUserChallenge")
            multipartFormData.appendBodyPart(data: "comment".dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)!, name :"comment")
            multipartFormData.appendBodyPart(data:"\(0.00)".dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)!, name :"latitude")
            multipartFormData.appendBodyPart(data:"\(0.00)".dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)!, name :"longitude")
            multipartFormData.appendBodyPart(data:"India".dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)!, name :"location")
        },
        encodingCompletion: { encodingResult in
            switch encodingResult {
            case .Success(let upload, _, _):
                upload.responseJSON { request, response, JSON, error in


                }
            case .Failure(let encodingError):

            }
        }
    )
