Question

我正在尝试使用Alamofire将图像与其他帖子参数一起上传。

查看我看到的文档：

Alamofire.upload(
    .POST,
    "https://httpbin.org/post",
    multipartFormData: { multipartFormData in
        multipartFormData.appendBodyPart(fileURL: unicornImageURL, name: "unicorn")
        multipartFormData.appendBodyPart(fileURL: rainbowImageURL, name: "rainbow")
    },
    encodingCompletion: { encodingResult in
        switch encodingResult {
        case .Success(let upload, _, _):
            upload.responseJSON { response in
                debugPrint(response)
            }
        case .Failure(let encodingError):
            print(encodingError)
        }
    }
)

但我怎样才能上传一系列图片，如：

var arrayOfImages: [UIImage] = [some images...]

与其他帖子数据一起：

let parameters: [String: AnyObject] = [
            "id": id,
            "title": title,
            "desc": description,
            "images[]": arrayOfImages
        ]

    func uploadProfileGIF(imageArray: NSMutableArray){
    var count = 0
    let bucketname = DAO.getBucketNameForLoggedInUser()
    let uploadUrl = "https://whatever.com/whatever"
    for i in imageArray{
        var objectname = "picture" + String(count)
        let image = i;
        //Turn image into data
        let imageData: NSData = UIImagePNGRepresentation(image as! UIImage)!
        let params = ["objectname" : objectname, "bucketname" : bucketname!, "isGifImgae" : "True", "content_type" : "image/jpeg"]

        let manager = AFHTTPSessionManager()
        manager.POST(uploadUrl, parameters: params, constructingBodyWithBlock: { (AFMultipartFormData) in

            AFMultipartFormData.appendPartWithFileData(imageData, name: "file", fileName: "image", mimeType: "image/jpeg")
            }, progress: nil, success: { (s:NSURLSessionDataTask, response) in
                print(response)
        }) { (s:NSURLSessionDataTask?, e:NSError?) in
            print(e)
        }
        count+=1
    }

}

这就是我这样做的方式。希望这可以帮助。它的AlamoFire，它是一个POST请求，我想是一个不同的语法。只是一个for循环，它为数组中的每个图像进行API调用。

编辑：

因此，不要使用for循环并单独调用API五次，只需更改AFMultipartofrmdata的名称即可。当您访问文件时，传入5个文件然后在您的API中，只需按名称访问它们。例如，我的API抓取文件的方式就是这样的

data = self.request.get('file')

现在数据是我的图像，我可以这样上传。只需在同一API调用中执行五次不同的操作即可。

    AFMultipartFormData.appendPartWithFileData(imageData1, name: "file1", fileName: "image", mimeType: "image/jpeg")
    AFMultipartFormData.appendPartWithFileData(imageData2, name: "file2", fileName: "image", mimeType: "image/jpeg")
    AFMultipartFormData.appendPartWithFileData(imageData3, name: "file3", fileName: "image", mimeType: "image/jpeg")
    AFMultipartFormData.appendPartWithFileData(imageData4, name: "file4", fileName: "image", mimeType: "image/jpeg")
    AFMultipartFormData.appendPartWithFileData(imageData5, name: "file5", fileName: "image", mimeType: "image/jpeg")

然后只需在for循环中指定名称和NSData。

然后在API方面，有类似的东西;

image1 = self.request.get('file1')
image2 = self.request.get('file2')
image3 = self.request.get('file3')
image4 = self.request.get('file4')
image5 = self.request.get('file5')

希望这有帮助！这就是我改变了我的API调用，而不是为每个用户调用5次不同的时间。
