Hi guys,
today is day 14 out of 100 days of golang coding.
This time I was playing with github issues api and made small script which create new issues in given repository. However to use the code you would need to obtain github personal token key.
The interesting part was to make http post request with custom headers.
package main
import (
"bytes"
"encoding/json"
"flag"
"fmt"
"io/ioutil"
"log"
"net/http"
)
func main() {
token := flag.String("token", "", "github auth token")
repo := flag.String("repo", "", "github owner/repo e.g. golang/go")
title := flag.String("title", "", "title for new issue")
body := flag.String("body", "", "body for new issue")
flag.Parse()
if *token == "" || *title == "" || *repo == "" {
log.Fatal("--token, --repo and --title parameters must be provided")
}
create(*repo, *title, *body, *token)
}
// NewIssue - specify data fields for new github issue submission
type NewIssue struct {
Title string `json:"title"`
Body string `json:"body"`
}
func create(ownerRepo, title, body, token string) {
apiURL := "https://api.github.com/repos/" + ownerRepo + "/issues"
//title is the only required field
issueData := NewIssue{Title: title, Body: body}
//make it json
jsonData, _ := json.Marshal(issueData)
//creating client to set custom headers for Authorization
client := &http.Client{}
req, _ := http.NewRequest("POST", apiURL, bytes.NewReader(jsonData))
req.Header.Set("Authorization", "token "+token)
resp, err := client.Do(req)
if err != nil {
log.Fatal(err)
}
defer resp.Body.Close()
if resp.StatusCode != http.StatusCreated {
fmt.Printf("Response code is is %d\n", resp.StatusCode)
body, _ := ioutil.ReadAll(resp.Body)
//print body as it may contain hints in case of errors
fmt.Println(string(body))
log.Fatal(err)
}
}
Example usage is as follow:
go build github_issue.go ./github_issue --token="5daf49b235c41d53ba6fsfasdfasdfasfsad" --repo="vorozhko/go-tutor" --title="my new issue 3" --body="test"
