Alamofire上载包含多部分/表单数据的图片 [英] Alamofire upload image with multipart/form-data

问题描述

我正在寻找一个有效的示例代码，以使用Alamofire上载具有多部分/表单数据的图像

i am looking for a working sample code to upload an image with multipart/form-data using Alamofire

我无法使用此代码来处理我的项目

i can't get this code to work with my project

Alamofire.upload(
    .POST,
    URLString: "http://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 { request, response, JSON, error in
                println(JSON)
            }
        case .Failure(let encodingError):
            println(encodingError)
        }
    }
)

此代码有此错误Could not find member 'POST'

有人说，如果您使用Alamofire.Method.POST，它将解决此问题，但我却收到此错误，而Cannot invoke 'upload' with an argument list of type '(Method, URLString: String, multipartFormData: (_) -> _, encodingCompletion: (_) -> _)'

some people said that if you use Alamofire.Method.POST it will fix the issue but i got this error instead Cannot invoke 'upload' with an argument list of type '(Method, URLString: String, multipartFormData: (_) -> _, encodingCompletion: (_) -> _)'

如果有人对此错误有解释或有其他可行的示例，请多多帮助.

if anyone has explanation for this error or have another working sample , would appreciate your help.

推荐答案

这是cocoapods的安装问题，我不得不将podfile更新为这样

it was cocoapods installation issue i had to update the podfile to be like this

platform :ios, '8.0'
use_frameworks!

target 'ProjectName' do

pod 'Alamofire', :git => 'https://github.com/Alamofire/Alamofire.git', :branch => 'master'

end
target 'ProjectNameTests' do
end

以便我可以获得支持MultipartFormData
