转到net / http请求正文始终为nil

Question

The http request body is always nil. Why is this happening? I am using the gokit toolkit. Below code is part of the handler.

    func decodeAddRequest(_ context.Context, r *http1.Request) (interface{}, error) {
    req := endpoint.AddRequest{}
    p, _ := ioutil.ReadAll(r.Body)
    fmt.Printf("%s
", p)
    err := json.NewDecoder(r.Body).Decode(&req)
    return req, err
}

My POST JSON request looks like this

{
    "title": "test test",
    "complete": false
}

And what gets saved to the database is

{
    "title": "",
    "complete": false
}

The type are:

type AddRequest struct {
    Todo io.Todo `json:"todo"`
}

type Todo struct {
    Id       bson.ObjectId `json:"id" bson:"_id"`
    Title    string        `json:"title" bson:"title"`
    Complete bool          `json:"complete" bson:"complete"`
}

Answer 1

The JSON is for a todo item, not for a CreateRequest. Unmasrhal to the todo item:

err := json.NewDecoder(r.Body).Decode(&req.Todo)
