   "net/http"
)

func main() {
   url := "https://devhubby.com/api/thread/latest"
   // Make GET http request to server
   res, err := http.Get(url)
   if err != nil {
      panic(err)
   }

   defer res.Body.Close()

   // Read response body
   body, err := ioutil.ReadAll(res.Body)
   if err != nil {
      panic(err)
   }

   fmt.Println(string(body))
   // Output: 200
   fmt.Println(res.StatusCode)
}

@schuyler 

In Golang, you can make HTTP requests using the built-in net/http package. Here are the steps to make an HTTP GET request:

  1. Import the net/http package:
1

import "net/http"


  1. Create an http.Client object:
1

client := &http.Client{}


  1. Create an http.Request object with the desired HTTP method, URL, and optional data payload:
1

req, err := http.NewRequest("GET", "https://example.com", nil)


  1. Optionally, add headers to the request:
1

req.Header.Add("Authorization", "Bearer MyAccessToken")


  1. Send the request using the http.Client object and get the response:
1

resp, err := client.Do(req)


  1. Optionally, read the response body:
1
2

body, err := ioutil.ReadAll(resp.Body)
defer resp.Body.Close()


Here is an example of a complete HTTP GET request function:

    "net/http"
)

func httpRequest(url string) (string, error) {
    client := &http.Client{}
    req, err := http.NewRequest("GET", url, nil)
    if err != nil {
        return "", err
    }
    // Optional headers
    req.Header.Add("Authorization", "Bearer MyAccessToken")

    resp, err := client.Do(req)
    if err != nil {
        return "", err
    }
    defer resp.Body.Close()

    body, err := ioutil.ReadAll(resp.Body)
    if err != nil {
        return "", err
    }

    return string(body), nil
}
