在Swift中使用Alamofire时如何获取响应头？ [英] How to get response headers when using Alamofire in Swift?

问题描述

我正在使用 Alamofire 获取我的Rest（POST）请求并无缝获取JSON响应。但我只能访问响应机构。我想获得响应标头。使用Alamofire时难道不可能吗？

I'm using Alamofire for my Rest (POST) request and getting JSON response seamlessly. But i can access only response body. I want to get response headers. Isn't it possible when using Alamofire?

这是我的代码片段：

@IBAction func loginButtonPressed(sender: UIButton) {
    let baseUrl = Globals.ApiConstants.baseUrl
    let endPoint = Globals.ApiConstants.EndPoints.authorize

    let parameters = [
        "apikey": "api_key_is_here",
        "apipass": "api_pass_is_here",
        "agent": "agent_is_here"
    ]

    Alamofire.request(.POST, baseUrl + endPoint, parameters: parameters).responseJSON {
        (request, response, data, error) in let json = JSON(data!)

        if let result = json["result"].bool {
            self.lblResult.text = "result: \(result)"
        }  
    }
}

推荐答案

由于回复是 NSHTTPURLResponse 类型，您应该能够获得如下所示的标题：

As response is of NSHTTPURLResponse type, you should be able to get the headers as followed:

response.allHeaderFields
