Scenario: Consider the following code:
var querystring = require('querystring');
var ParamsWithValue = querystring.parse(req._url.query);
Then I am able to read any query string's value.
E.g: If requested string is http://www.website.com/Service.aspx?UID=Trans001&FacebookID=ae67ea324
I can get the values of query string with codes ParamsWithValue.UID
& ParamsWithValue.FacebookID
respectively.
Issue: I am able to get the values of any number of parameters passed in the same way described above. But for second time onwards I am getting the following error in response on browser.
Error:
{"code":"InternalError","message":"Cannot read property 'query' of undefined"}
Question: What is wrong in the approach to read the query string from the URL.
Note: I don't want to use any frameworks to parse it. I am trying to depend on built-in modules only.
I think you need req.url rather than req._url.
req.url is a string, if you want a URI instance use require('url').parse(req.url)
So, you should finally have:
var ParamsWithValue = querystring.parse(require('url').parse(req.url).query);
Edit: I corrected a typo in point 1, the last req.url -> req._url
