如何将GCDWebServer请求从iOS应用程序重定向到外部主机

Question

In my iOS app I'm trying to add a simple GCDWebServer redirect handler like so:

self.webServer!.addHandlerForMethod("GET", 
    pathRegex: "/api/.*",
    requestClass: GCDWebServerRequest.self,
    processBlock: { request in
        let url = NSURL(string: "http://external.host\(request.URL!.absoluteString)")
        return GCDWebServerResponse(redirect: url, permanent: true)
    }
)

but my url is malformed. How do I properly construct an NSURL from a given host and GCDWebServerRequest.URL ?

Answer 1

request.URL是一个NSURL对象，因此，要使用它与另一个主机组成另一个URL，就必须通过访问其path拆分它，如下所示：

let url = NSURL(string: "http://host.com\(request.URL!.path)")
