GO: HTTP Client POST JSON

Hier ein Beispiel Struct -> JSON an einen GIN Microwebservice.

Client

package main

import (
	"bytes"
	"encoding/json"
	"fmt"
	"net/http"
)

type Lala struct {
	Name    string
	Vorname string
}

func main() {
	// Create the record
	apiurl := "http://localhost:8080/api/v1/create_record"

	var record Lala

	record.Vorname = "Hans"
	record.Name = "Dampf"

	m, _ := json.Marshal(record)

	apireq, apierr := http.NewRequest("POST", apiurl, bytes.NewBuffer(m))
	apireq.Header.Set("Content-Type", "application/json")

	apiclient := &http.Client{}

	apiresp, apierr := apiclient.Do(apireq)

	if apierr != nil {
		fmt.Printf("1 %v", apierr)
	}

	defer apiresp.Body.Close()

	if apiresp.StatusCode == http.StatusCreated {
		fmt.Println("0 - Record created.")
	} else {
		fmt.Printf("1 - ERR: %v", apiresp.Body)
	}
}

Server

package main

import (
	"fmt"
	"net/http"

	"github.com/gin-gonic/gin"
)

type Lala struct {
	Name    string
	Vorname string
}

func CreateRecord(c *gin.Context) {
	var data Lala

	if err := c.BindJSON(&data); err != nil {
		c.JSON(http.StatusBadRequest, gin.H{"message": "error occured"})
	} else {
		fmt.Println(data)
		c.JSON(http.StatusCreated, gin.H{"data": data})
	}
}

func main() {
	r := gin.Default()
	r.POST("/api/v1/create_record", CreateRecord)

	r.Run()
}
