Create a Nodejs server that accepts requests and creates res

Create a Node.js server that accepts requests and creates responses and host it on Apigee.

– The server should accept GET, POST, PUT and DELETE requests. – Any other requests coming in should be rejected.

If the server accepts a request, it should respond with information about the request.

– The server should respond with the name and value of any query parameters sent in. If no headers or query parameters are sent in, then the response should say so.

– Some headers are generated automatically, like host and user-agent. It’s fine to have these appear in the response.

If the server rejects a request, it should respond with a simple statement saying it doesn’t support the HTTP method.

The server should have four different URNs that only accept a given HTTP method, while reject the other methods.

– /gets should only accept GET requests while rejecting others.

– /posts should only accept POST requests while rejecting others.

– /puts should only accept PUT requests while rejecting others.

– /deletes should only accept DELETE requests while rejecting others.

– Any requests made to the base URL (no URN specified) should also be rejected.

Solution

var http = require(\'http\');

var express = require(\'express\');

var app = express();

app.all(\'/\', function (req, res) {
  
   res.status(403).send(\'Request Rejected: no URN specified\');
});

app.all(\'/gets\', function (req, res) {
  
if(req.method == \'GET\') {
  
if(Object.keys(req.query).length > 0) {
res.send(req.query);
  
} else {
res.send(\'No query parameters were sent in.\');
}
  
} else {
  
res.status(403).send(\'Request Rejected: HTTP Method not supported.\');
}
});

app.all(\'/posts\', function (req, res) {
  
if(req.method == \'POST\') {
  
if(Object.keys(req.query).length > 0) {
res.send(req.query);

} else {
res.send(\'No query parameters were sent in.\');
}
  
} else {
  
   res.status(403).send(\'Request Rejected: HTTP Method not supported.\');
}
});

app.all(\'/puts\', function (req, res) {
  
if(req.method == \'PUT\') {
  
if(Object.keys(req.query).length > 0) {
res.send(req.query);
  
} else {
res.send(\'No query parameters were sent in.\');
}

} else {
  
   res.status(403).send(\'Request Rejected: HTTP Method not supported.\');
}
});

app.all(\'/deletes\', function (req, res) {
  
if(req.method == \'DELETE\') {
  
if(Object.keys(req.query).length > 0) {
res.send(req.query);
  
} else {
res.send(\'No query parameters were sent in.\');
}
  
} else {
  
   res.status(403).send(\'Request Rejected: HTTP Method not supported.\');
}
});

app.all(\'*\', function (req, res) {
  
res.status(403).send(\'Request Rejected: URN does not support the HTTP Method.\');
});

var server = app.listen(8080, function() {
   var host = server.address().address;
   var port = server.address().port;
  
   console.log(\'Node.js server listening at http:%s:%s\', host, port)
});
