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

问题描述

由于迁移到 Swift 3，我发现很难编译我使用 Alamofire 的项目.

上传multipartFormData时出现问题:

Alamofire.upload(.POST, URL, headers: headers, multipartFormData: {多部分表单数据...})

<块引用>

对成员'upload(_:to:method:headers:)'的不明确引用

非常感谢任何帮助，提前致谢！

已解决:

 Alamofire.upload(multipartFormData: { (multipartFormData) inmultipartFormData.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切换结果{案例.success(让上传，_，_):upload.responseJSON { 响应输入self.delegate?.showSuccessAlert()print(response.request)//原始 URL 请求打印(响应.响应)//URL响应打印(响应数据)//服务器数据print(response.result)//响应序列化的结果//self.showSuccesAlert()self.removeImage("frame", fileExtension: "txt")如果让 JSON = response.result.value {打印(JSON:(JSON)")}}案例.失败(让编码错误):self.delegate?.showFailAlert()打印(编码错误)}})

这是在 Swift 3 中应该如何实现上传方法

解决方案

例如，在 Swift 3 中使用 Alamofire 4.0.0:

(确保您已准备好 4.0.0，因为您似乎还没有更新您的 Alamofire)

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

或

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

所以headers需要通过URL请求传递:

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

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

The problem occurs when uploading multipartFormData:

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

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

Any help much appreciated, thanks in advance!

RESOLVED:

 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)
            }

    })

This is how upload method should be implemented in Swift 3

解决方案

For example, using Alamofire 4.0.0 in Swift 3:

(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
    })

or

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

So headers need to be passed by URL request:

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