Build a static server based on node. js

Principle:

1. Parse the request URL to the corresponding file path;
2. Determine if the file exists;
3. If present, read the file content output;

Realize:

varPath=Require(' path '),Fs=Require(' FS ');Require(' http ').Createserver(function(Req,Res) {    //Parse file path, default to the current directory as the root directory to find files    //This can be done by configuring the root value to find files for the relative root directory    varFile=Path.Normalize('. ' +Req.URL);Console.Log(' Trying to serve ',File);    functionReportError(Err) {Console.Log(Err);Res.Writehead( -);Res.End(' Internal Server Error ');    }//Determine if the file existsPath.exists(File, function(Exists) {        //file exists, then read file stream, output        if (Exists) {Fs.Stat(File, function(Err,Stat) {                varRs;                if (Err) {                    returnReportError(Err);                } if (Stat.isdirectory()) {Res.Writehead(403);Res.End(' Forbidden ');                } Else {Rs=Fs.Createreadstream(File);Rs. on(' ERROR ',ReportError);Res.Writehead( $);Rs.Pipe(Res);                }            });        //404        } Else {Res.Writehead(404);Res.End(' not found ');        }    });}).Listen(4000);

At last:

The above is just an example of implementing a static server, and production applications still prefer nginx.
