如何在GCDWebServer中限制連接到允許的IP地址

Question

我在玩GCDWebServer類（很棒！），並想知道是否可以通過遠程IP限制允許的連接。

server.addDefaultHandlerForMethod("GET", requestClass: GCDWebServerRequest.self, processBlock: {request in 

    let remote = request.remoteAddressString.substringToIndex(request.remoteAddressString.lastIndexOf(":")!) 
    let local = request.localAddressString.substringToIndex(request.localAddressString.lastIndexOf(":")!) 

    print("\(remote) vs \(local)") 
    if remote == local { 
     return nil 
    } 

    //Forbidden 
    return GCDWebServerResponse(statusCode: 403); 

}) 

上面我希望將工作，但它不是，我的意思是，當IP的不同將其發送403禁止但除此之外，它與結束：

[DEBUG] Connection aborted with status code 500 on socket 13

誰能幫助我？

P.S.下面還doenst工作

server.addDefaultHandlerForMethod("GET", 
             requestClass: GCDWebServerRequest.self, 
             processBlock: {request in 

    print(request.remoteAddressString) 
    print(request.localAddressString) 

    let remote = request.remoteAddressString.substringToIndex(request.remoteAddressString.lastIndexOf(":")!) 
    let local = request.localAddressString.substringToIndex(request.localAddressString.lastIndexOf(":")!) 

    print("\(remote) vs \(local)") 
    if remote == local { 
     return GCDWebServerResponse(statusCode: 200) 
    } 
    //Forbidden 
    return GCDWebServerResponse(statusCode: 403); 
})

爲GCDWebServerProcessBlock見GCDWebServer.h：

塊必須返回GCDWebServerResponse或零誤差，這將導致500 HTTP狀態代碼返回給客戶端。
