Params provides 'window.location.search' on client and 'request.requestedUrl.query' on server as a Map

##Params 0.0.2

Params is a package that provides window.location.search on client and request.requestedUrl.query on server as a Map

  1. install via pub

##On the client


  1. Import the package inside your client like this

     import 'package:params/client.dart';
    
  2. At the beginning of your main function call add

     initParams();
    
  3. If the window location is http://127.0.0.1:3030/Rainbow/web/rainbow.html?id=1&language=dart the Standart client params map looks like this

     {
       id: 1, 
       language: dart, 
       _ancestorOrigins: [], 
       _hash: , 
       _host: 127.0.0.1:3030, 
       _hostname: 127.0.0.1, 
       _href: http://127.0.0.1:3030/Rainbow/web/rainbow.html?id=1&language=dart,
       _origin: http://127.0.0.1:3030, 
       _pathname: /Rainbow/web/rainbow.html, 
       _port: 3030, 
       _protocol: http:, 
       _search: ?id=1&language=dart
     }
    

Now you can access the search values using params['key'] like below

   void main() {
     initParams();
     if(params['id'] != null){
       String id = params['id'];
       String language = params['language'];
       var url = http://127.0.0.1:8090/loadItem?id=$id&language=$language;
       var request = HttpRequest.getString(url).then(displayUserAccount);
     }else{
       content.text="no UserAccount id available";
     }
   };

##On the server


  1. Import the package inside your server like this

     import 'package:params/server.dart';
    
  2. At the beginning of your server.listen function add

     initParams();
    
  3. If a HTTP request is made to http://127.0.0.1:8090/loadItem?id=1&language=dart

the standart server params map looks like this:

    {
      id: 1,
      language: dart,
      _query: id=1&language=dart, 
      _authority: 127.0.0.1:8090, 
      _host: 127.0.0.1, 
      _port: 8090, 
      _path: /loadItem, 
      _pathSegments: [loadItem], 
      _queryParameters: {
        id: 1,
        language: dart
      }, 
      _isAbsolute: true, 
      _hasAuthority: true, 
      _origin: http://127.0.0.1:8090, 
      __isPathAbsolute: true, 
      _hashCode: 277712556
    }

Now you can access the query values using params['key'] like below

   server.listen((HttpRequest request) {
     initParams(request);
     //if request.requestedUrl.query is "id=1&language=dart"
     String id = params['id'];
     String language = params['language'];
     switch (request.method) {
       case "GET": 
         handleGet(request);
         break;
       case "POST": 
         handlePost(request);
         break;
       case "OPTIONS": 
         handleOptions(request);
         break;
       default: defaultHandler(request);
     }
   }
