我如何使用：作为拆分器并创建2个单独的字符串变量来拆分node.js函数中的querydata

Question

okay so here is my node.js script

  // Configure our HTTP server to respond with Hello World to all requests.
  var server = http.createServer(function (request, response) {
  var queryData = url.parse(request.url, true).query;
  response.writeHead(200, {"Content-Type": "text/plain"});

  if (queryData.name) {
    // user told us their name in the GET request, ex: http://host:8000/?name=Tom
    var exec = require('child_process').exec;

    exec ("casperjs test.js " + queryData.name + '\n',function(err, stdout, stderr) {

        response.end(stdout);

    });

  } else {
    response.end("Contact Admin - Not Working\n");
  }
});

// Listen on port 8000, IP defaults to 127.0.0.1
server.listen(8283);

basically I want to be able to split querydata.name into to seprate variable to use in the exec

here is an example of what I want to do

split querydata.name into 
value1
and
value2

so I can use them like this

exec ("casperjs test.js " + value1 + " " + value2 + '\n',function(err, stdout, stderr)

can anyone help me achieve this the string needs splitting using : as the splitter

----------------------EDIT CODE I HAVE TRIED this now works edited again ---------------------------------



var server = http.createServer(function (request, response) {
  var queryData = url.parse(request.url, true).query;
  response.writeHead(200, {"Content-Type": "text/plain"});

  if (queryData.name) {
    // user told us their name in the GET request, ex: http://host:8000/?name=Tom
    var basevalue = queryData.name;
    var value = basevalue.split (":");
    var exec = require('child_process').exec;

    exec ("casperjs test.js " + value[0] + " " + value[1] + '\n',function(err, stdout, stderr) {

        response.end(stdout);

    });

  } else {
    response.end("Contact Admin - Not Working\n");
  }
});

// Listen on port 8000, IP defaults to 127.0.0.1
server.listen(8283);

and the error I get

[root@cyber-hosted ~]# node no1.js

/root/no1.js:1
on (exports, require, module, __filename, __dirname) { var server = http.creat
                                                                ^

I just cannot get the split working correctly

Your problem isn't with the split. The stacktrace you posted states ReferenceError: http is not defined .

This is because you need to require any modules you use in your code.

If you add the line var http = require('http') to the top of your file, it should fix the problem.

edit: You'll need to add var url = require('url') as well.

edit2: Tested this code, it should work:

var http = require('http')
var url = require('url')

var server = http.createServer(function (request, response) {
  var queryData = url.parse(request.url, true).query;
  response.writeHead(200, {"Content-Type": "text/plain"});

  if (queryData.name) {
    // user told us their name in the GET request, ex: http://host:8283/?name=Tom

    var exec = require('child_process').exec;

    exec ("casperjs test.js " + queryData.name + '\n',function(err, stdout, stderr) {

        response.end(stdout);

    });

  } else {
    response.end("Contact Admin - Not Working\n");
  }
});

server.listen(8283);
