可以有人给一个示例代码如何添加一个请求处理程序到dart中的HttpServer对象？ [英] Can some one give be a sample code how to add a request handler to a HttpServer Object in dart?

问题描述

我对飞镖编程非常新，任何帮助都很感激。

  void main（）{
 var server = new HttpServer（）; 
 server.listen（'127.0.0.1'，8080）; 
服务器。 
 addRequestHandler（
 accept（HttpRequest function）=> acceptInput（request，response），handler）; 
} 
  

我想将下面的函数添加到请求处理程序。
server.addrequestHandler（）
我想这样做，以便我可以添加许多请求处理程序，包括一个用于websockets
示例或教程非常有帮助。

为了简单起见，我希望将每个处理程序保持在单独的函数中。

  void acceptInput（HttpRequest request，HttpResponse response）{
 print（request.connectionInfo.toString（））; 
 print（request.queryParameters.toString（））; 
 response.outputStream.write（'Hello dude'.charCodes）; 
 response.outputStream.close（）; 
} 
  

注意：我知道我的void main代码是错误的以使其包含acceptInput函数。

解决方案

实际上，你真的很接近。 / p>

尝试此操作：

  var server = new HttpServer 
 server.addRequestHandler（
（req）=> req.path =='/ save'，
 handleSave）; 
 server.addRequestHandler（
（req）=> req.path =='/ delete'，
 handleDelete）; 
 server.defaultRequestHandler = new StaticFileHandler（basePath）.onRequest; 
  

其中 handleSave 和 handleDelete 只是函数，如：

  handleSave（HttpRequest req，HttpResponse resp）{
 // ... 
} 
  

I am very new to the dart programming any help is appreciated.

void main() {
  var server = new HttpServer();
  server.listen('127.0.0.1', 8080);
  server.
  addRequestHandler(
  accept(HttpRequest function) => acceptInput(request, response), handler);
 }

I want to add the function below to the request handler. server.addrequestHandler() I would like to do this so that I can add many request handlers as such including one for websockets A sample or a tutorial would be very helpful.

I want to keep each handler in a separate function just for simplicity.

void acceptInput(HttpRequest request,HttpResponse response){
  print(request.connectionInfo.toString());
  print(request.queryParameters.toString());
  response.outputStream.write('Hello dude'.charCodes);
  response.outputStream.close();
}

Note:I know my void main code is wrong I need help to make it correct so that it incorporates the acceptInput Function.

解决方案

Actually, you're really close.

Try this:

  var server = new HttpServer();
  server.addRequestHandler(
      (req) => req.path == '/save',
      handleSave);
  server.addRequestHandler(
      (req) => req.path == '/delete',
      handleDelete);
  server.defaultRequestHandler = new StaticFileHandler(basePath).onRequest;

Where handleSave and handleDelete are just functions, like:

handleSave(HttpRequest req, HttpResponse resp) {
  // ...
}
