Question

我正在玩GCDWebServer类（很棒！）并且想知道是否可以通过远程IP限制允许的连接。

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);

})

我希望上面会有效，但不是，我的意思是当IP不同时它会发送403 Forbidden，否则它会以最终结果：

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

任何人都可以帮我吗？

P.S。以下也是最重要的工作

    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);
})

GCDWebServer.h见GCDWebServerProcessBlock：

该块必须在出错时返回GCDWebServerResponse或nil，这将导致返回给客户端的500 HTTP状态代码。

如何在GCDWebServer中限制与允许的IP的连接
