如何在Go中的POST请求中发送JSON字符串

I tried working with Apiary and made a universal template to send JSON to mock server and have this code:

package main

import (
    "encoding/json"
    "fmt"
    "github.com/jmcvetta/napping"
    "log"
    "net/http"
)

func main() {
    url := "http://restapi3.apiary.io/notes"
    fmt.Println("URL:>", url)

    s := napping.Session{}
    h := &http.Header{}
    h.Set("X-Custom-Header", "myvalue")
    s.Header = h

    var jsonStr = []byte(`
{
    "title": "Buy cheese and bread for breakfast."
}`)

    var data map[string]json.RawMessage
    err := json.Unmarshal(jsonStr, &data)
    if err != nil {
        fmt.Println(err)
    }

    resp, err := s.Post(url, &data, nil, nil)
    if err != nil {
        log.Fatal(err)
    }
    fmt.Println("response Status:", resp.Status())
    fmt.Println("response Headers:", resp.HttpResponse().Header)
    fmt.Println("response Body:", resp.RawText())

}

This code doesn't send JSON properly, but I don't know why. The JSON string can be different in every call. I can't use Struct for this.

    I'm not familiar with napping, but using Golang's net/http package works fine (playground):

    func main() {
        url := "http://restapi3.apiary.io/notes"
        fmt.Println("URL:>", url)
    
        var jsonStr = []byte(`{"title":"Buy cheese and bread for breakfast."}`)
        req, err := http.NewRequest("POST", url, bytes.NewBuffer(jsonStr))
        req.Header.Set("X-Custom-Header", "myvalue")
        req.Header.Set("Content-Type", "application/json")
    
        client := &http.Client{}
        resp, err := client.Do(req)
        if err != nil {
            panic(err)
        }
        defer resp.Body.Close()
    
        fmt.Println("response Status:", resp.Status)
        fmt.Println("response Headers:", resp.Header)
        body, _ := ioutil.ReadAll(resp.Body)
        fmt.Println("response Body:", string(body))
    }
