System.Console.WriteLine ("This is one Hello")
Printfn "This is another Hello"
After saving the code as a Hello.fs file, we need to build a. NET assembly on the command line by Fsc.exe compilation. The compiled code on the command line is as follows:
FSC Hello.fs
With the above code, we get the common executable (. exe file), which is the start of our F #--hello.exe.
F # Tip: F # is a compiled language on the. NET platform, but it can still run
path is legitimate
Match Content-type according to file suffix
Reads the file data and sets the Content-length, or returns 404 if the file does not exist
Sets the response header and returns the response header and data to the browser.
Next we follow the process request and response request two steps, say code implementation. Let's take a look at the core code structure, as follows:/*** TINYHTTPD * * @authorCODE4WT* @date 2018-03-26 22:28:44 */ Public classTINYHTTPD {Private St

Pleace sure the server is Live ") println (e.getmessage) println (e.getstacktracestring) receiver FOREAC h {_.stop ()}}}}After you have customized receiver for spark streaming , you can use it in your app:def main (args:array[string]) { new Thread ("Fqueue sender") { override def run () {senddata ()} }.start ()
