带GCDWebServer的iOS重新路由请求(不重定向) [英] iOS re-routing requests w/ GCDWebServer (not redirecting)

问题描述

我想用GCDWebServer在iOS上创建服务器，该服务器将接受对localhost的请求，然后从另一个url(视频文件)中提取数据并将数据流式传输到响应.我打算使用普通的NSURLConnection，并且在NSURLConnection回调的didReceiveData中，我想将此数据传递给GCDWebServerResponse.

I want to create a server on iOS with GCDWebServer, which will accept request to localhost, and then, draw the data from another url (a video file) and stream the data to the response. I intend to use plain NSURLConnection, and in the didReceiveData of the NSURLConnection callback, I want to pass this data to the GCDWebServerResponse.

我很难弄清楚如何才能保持打开请求的连接，以便可以使用NSURLConnection发起另一个请求，并开始将数据提供给响应.

I am having a hard time to figure out how can I keep the connection from a request open, so that I can initiate another request w/ NSURLConnection, and start serving data to the response.

有什么办法可以做到吗?我需要创建一个新的GCDWebServerStreamedResponse子类吗?

Is there any way I can do that? Do I need to create a new subclass of GCDWebServerStreamedResponse?

谢谢.

推荐答案

您无需将GCDWebServerStreamedResponse子类化，只需实例化它并使用GCDWebServerAsyncStreamBlock回调即可.

You don't need to subclass GCDWebServerStreamedResponse but simply instantiate it and use the GCDWebServerAsyncStreamBlock callback.

在回调中，创建您的NSURLConnection并使其异步运行.然后，只要有新数据可用(例如，来自-didReceiveData:的数据)，就使用GCDWebServerBodyReaderCompletionBlock将其传递通过，而当没有更多数据可用时，传递一个空的NSData.

In the callback, create your NSURLConnection and have it run asynchronously. Then whenever new data is available (e.g. from -didReceiveData:), pass it through using the GCDWebServerBodyReaderCompletionBlock and when there is no more data available, pass an empty NSData.

有关类似内容，请参见 GCDWebServer自述文件中的高级异步版本".概念.

See the "Advanced asynchronous version" in the GCDWebServer README for a similar concept.
