如何检索请求的响应标头？以下是我提出的要求.
Alamofire.request(.GET,requestUrl,parameters:parameters,headers: headers)
.responseJSON { response in switch response.result {
case .Success(let JSON):
...
case .Failure(let error):
...
}
提前致谢！
如果响应是NSHTTPURLResponse的类型,则可以从response.allHeaderFields获取标头.
原文链接：/swift/320035.html因此,当您使用Alamofire responseJSON时,您可以访问NSHTTPURLResponse属性,如下所示：
Alamofire.request(.GET,headers: headers).responseJSON {
response in
print(response.response?.allHeaderFields)
}
正如苹果文档所说：
A dictionary containing all the HTTP header fields received as part of the server’s response. By examining this dictionary clients can see the “raw” header information returned by the HTTP server.
The keys in this dictionary are the header field names,as received from the server. See RFC 2616 for a list of commonly used HTTP header fields.
因此,要获得响应标头中的内容类型,您可以通过以下方式访问它：
if let contentType = response.response?.allHeaderFields["Content-Type"] as? String {
// use contentType here
}
