Swift 3 Alamofire分段上传 [英] Swift 3 Alamofire multipart upload

问题描述

感谢迁移到Swift 3，我发现很难编译使用Alamofire的项目。

Thanks to migration to Swift 3, I find it difficult to compile my project that uses Alamofire.

上传multipartFormData时出现问题：

The problem occurs when uploading multipartFormData:

Alamofire.upload(.POST, URL, headers: headers, multipartFormData: {
        multipartFormData in
.
.
. 
}) 

模棱两可的参考会员'上传（_：to：方法：标题:)'

Ambiguous reference to member 'upload(_:to:method:headers:)'

任何帮助非常感谢，提前感谢！

Any help much appreciated, thanks in advance!

已解决：

 Alamofire.upload(multipartFormData: { (multipartFormData) in

        multipartFormData.append(fileData, withName: "file_pack", fileName: "file_pack", mimeType: "text/plain")


        for (key, value) in self.parameters {
            multipartFormData.append(value.data(using: String.Encoding.utf8)!, withName: key)
        }
        }, with: URL2, encodingCompletion: { (result) in

            switch result {
            case .success(let upload, _, _):

                upload.responseJSON { response in
                    self.delegate?.showSuccessAlert()
                    print(response.request)  // original URL request
                    print(response.response) // URL response
                    print(response.data)     // server data
                    print(response.result)   // result of response serialization
                    //                        self.showSuccesAlert()
                    self.removeImage("frame", fileExtension: "txt")
                    if let JSON = response.result.value {
                        print("JSON: \(JSON)")
                    }
                }

            case .failure(let encodingError):
                self.delegate?.showFailAlert()
                print(encodingError)
            }

    })

这是在Swift中实现上传方法的方法3

This is how upload method should be implemented in Swift 3

推荐答案

例如，在< Alamofire 4.0.0 中 Swift 3 ：

（确保你已准备好4.0.0，因为你好像还没有更新你的Alamofire）

(make sure you are 4.0.0 ready as it looks like you haven't updated your Alamofire yet)

Alamofire.upload(multipartFormData: { (multipartFormData) in
        // code
    }, to: URL, encodingCompletion: { (result) in
        // code
    })

或

Alamofire.upload(multipartFormData: { (multipartFormData) in
        // code
    }, with: URL, encodingCompletion: { (result) in
        // code
    })

所以标题需要通过网址请求传递：

So headers need to be passed by URL request:

let URL = try! URLRequest(url: "http://example.com", method: .get, headers: headers)
