Server and APIs

When we use http.createServer(callback). The callback function takes in two objects, what are these?

• request, response

• handler,response

• response,handler

• request,process

We want the content type of the response to be 'text/html'. Which of the following is the correct way to do it?

• res.setHeader('content-type', 'text/html')

• res.setHeader('content-type', 'application/json')

• res.writeHeader('content-type', 'text/html')

• res.writeHead('content-type', 'text/html')

To set the status code of response, what would be the correct syntax?

• res.writeHeader(200)

• res.writeHead(200)

• res.writeStatus(200)

• res.writeCode(200)

When we query for data from an api, what code do we return when that data is not found

• 400

• 422

• 404

• 419

When we build an API server, what content type do we set?

• text/html

• application/json

• application/api

• application/html

To read the url from the request, what property of req do we use?

• url

• path

• link

• none of the options

A request is creating a resource in your API server, the method is "req.method === ?"

• PUT

• PATCH

• GET

• POST

Select the correct option to read data from the request

• req.on('data', callback)

• res.on('data', callback)

• req.on('body', callback)

• res.on('body', callback)

How do we send data as part of the response

• res.writeData(data)

• res.write(data)

• res.json(data)

• res.writeJson(data)

if our req.url is '/v1/students/123', how would we get 123 from the url?

• req.url.split('/')[0]

• req.url.split('/')[1]

• req.url.split('/')[2]

• req.url.split('/')[3]
