HTTP Client

net/http package in go can be used to send request to other http servers (similar to fetch in JS)

Sending a request

Write a function sendRequest that gets the post details from https://jsonplaceholder.typicode.com/posts/1

package main

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

type post struct {
  UserId int    `json:"userId"`
  Id     int    `json:"id"`
  Title  string `json:"title"`
  Body   string `json:"body"`
}

func sendRequest(url string, ch chan string) {
  resp, error := http.Get(url)

  if error != nil {
    ch <- "Error while sending request"
  }

  defer resp.Body.Close()

  body, err := io.ReadAll(resp.Body)

  if err != nil {
    ch <- "Error while reading body"
  }

  p := post{}

  json.Unmarshal(body, &p)

  ch <- p.Title
}

func main() {
  ch := make(chan string)
  go sendRequest("https://jsonplaceholder.typicode.com/posts/1", ch)
  ans := <-ch
  fmt.Print(ans)
}
