Alamofire 4.0上传MultipartFormData标头

Question

我们如何在Alamofire 4.0的上传功能中添加认证标头？

下面是示例代码，但我认为没有办法在函数中添加标题。

Alamofire.upload(
    multipartFormData: { multipartFormData in 
     multipartFormData.append(unicornImageURL, withName: "unicorn") 
     multipartFormData.append(rainbowImageURL, withName: "rainbow") 
    }, 
    to: "https://httpbin.org/post", 
    encodingCompletion: { encodingResult in 
     switch encodingResult { 
     case .success(let upload, _, _): 
      upload.responseJSON { response in 
       debugPrint(response) 
      } 
     case .failure(let encodingError): 
      print(encodingError) 
     } 
    } 
) 

上一页alamofire的版本支持直接添加标题，但不是新的。有任何想法吗？

我得到了解决方案。

Alamofire.upload(multipartFormData:{ multipartFormData in 
     multipartFormData.append(unicornImageURL, withName: "unicorn") 
     multipartFormData.append(rainbowImageURL, withName: "rainbow")}, 
     usingThreshold:UInt64.init(), 
     to:"https://httpbin.org/post", 
     method:.post, 
     headers:["Authorization": "auth_token"], 
     encodingCompletion: { encodingResult in 
     switch encodingResult { 
     case .success(let upload, _, _): 
      upload.responseJSON { response in 
       debugPrint(response) 
      } 
     case .failure(let encodingError): 
      print(encodingError) 
     } 
    }) 

希望它能帮助你。
