Go: Building Web Applications

Handling endpoints

The final piece of the puzzle is the handlePolls function that will use the helpers to understand the incoming request and access the database, and generate a meaningful response that will be sent back to the client. We also need to model the poll data that we were working with in the previous chapter.

Create a new file called polls.go, and add the following code:

package main
import "gopkg.in/mgo.v2/bson"
type poll struct {
  ID      bson.ObjectId  `bson:"_id" json:"id"`
  Title   string         `json":"title""`
  Options []string       `json:"options"`
  Results map[string]int `json:"results,omitempty"`
}
