HTTP Client Util is a Go library for sending HTTP requests with custom headers.

This is a package that provides a set of functions for making HTTP requests with custom headers and request bodies, and unmarshaling the response bodies into JSON objects. It uses the net/http package for making HTTP requests and the encoding/json package for marshaling and unmarshaling JSON.

Supports sending GET, POST, PUT, and DELETE requests. Allows users to set custom headers for the request. Returns the response body as a byte array. Provides a simple API for sending HTTP requests.

To use HTTP Client Util in your Go program, import the httpclientutil package:

import "github.com/yourusername/httpclientutil"

Then, use one of the functions provided by the package to send an HTTP request with custom headers:

// Send an HTTP GET request with custom headers
headers := map[string]string{
	"User-Agent": "Mozilla/5.0",
	"Accept":     "application/json",
}
response, err := httpclientutil.Get("https://example.com", headers)

// Send an HTTP POST request with custom headers and body
headers = map[string]string{
	"Content-Type": "application/json",
}
body := []byte(`{"name": "John", "age": 30}`)
response, err = httpclientutil.Post("https://example.com/api/users", headers, body)

To make a GET request and unmarshal the response body into a JSON object, use the GetJSON function:

url := "https://jsonplaceholder.typicode.com/todos/1"
headers := map[string]string{"Content-Type": "application/json"}
var todo Todo
err := httpclient.GetJSON(url, headers, &todo)

To make a POST request and unmarshal the response body into a JSON object, use the PostJSON function:

url := "https://jsonplaceholder.typicode.com/todos"
headers := map[string]string{"Content-Type": "application/json"}
todo := Todo{Title: "Buy milk", Completed: false}
body, _ := json.Marshal(todo)
var newTodo Todo
err := httpclient.PostJSON(url, headers, body, &newTodo)

To make a PUT request and unmarshal the response body into a JSON object, use the PutJSON function:

url := "https://jsonplaceholder.typicode.com/todos/1"
headers := map[string]string{"Content-Type": "application/json"}
todo := Todo{ID: 1, Title: "Buy milk", Completed: true}
body, _ := json.Marshal(todo)
var updatedTodo Todo
err := httpclient.PutJSON(url, headers, body, &updatedTodo)

To make a DELETE request and unmarshal the response body into a JSON object, use the DeleteJSON function:

url := "https://jsonplaceholder.typicode.com/todos/1"
headers := map[string]string{"Content-Type": "application/json"}
var todo Todo
err := httpclient.DeleteJSON(url, headers, &todo)

To make a custom HTTP request with a method other than GET, POST, PUT, or DELETE, use the sendRequest function:

url := "https://jsonplaceholder.typicode.com/todos/1"
headers := map[string]string{"Content-Type": "application/json"}
method := "PATCH"
todo := Todo{ID: 1, Title: "Buy milk", Completed: true}
body, _ := json.Marshal(todo)
var updatedTodo Todo
respBody, err := httpclient.sendRequest(method, url, headers, body)
