Examples

Simple GET into a string

code with net/http	code with requests
req, err := http.NewRequestWithContext(ctx, http.MethodGet, "http://example.com", nil) if err != nil { // ... } res, err := http.DefaultClient.Do(req) if err != nil { // ... } defer res.Body.Close() b, err := io.ReadAll(res.Body) if err != nil { // ... } s := string(b)	s, err := goreq.New[string]("http://example.com"). Fetch(context.Backgroun()) fmt.Println(s)

POST a raw body

code with net/http	code with requests
body := bytes.NewReader(([]byte(`hello, world`)) req, err := http.NewRequestWithContext(ctx, http.MethodPost, "https://postman-echo.com/post", body) if err != nil { // ... } req.Header.Set("Content-Type", "text/plain") res, err := http.DefaultClient.Do(req) if err != nil { // ... } defer res.Body.Close() _, err := io.ReadAll(res.Body) if err != nil { // ... }	s, err := goreq.New[string]("https://postman-echo.com/post"). BodyRaw([]byte(`hello, world`)). Header("Content-Type", "text/plain"). Fetch(ctx)

GET a JSON object

code with net/http	code with requests
var post placeholder u, err := url.Parse("https://jsonplaceholder.typicode.com") if err != nil { // ... } u.Path = fmt.Sprintf("/posts/%d", 1) req, err := http.NewRequestWithContext(ctx, http.MethodGet, u.String(), nil) if err != nil { // ... } res, err := http.DefaultClient.Do(req) if err != nil { // ... } defer res.Body.Close() b, err := io.ReadAll(res.Body) if err != nil { // ... } err := json.Unmarshal(b, &post) if err != nil { // ... }	post, err := goreq.New[placeholder]("https://jsonplaceholder.typicode.com").IsJson(). Path(fmt.Sprintf("/posts/%d", 1)).Fetch(ctx)

POST a JSON object and parse the response

req := placeholder{
	Title:  "foo",
	Body:   "baz",
	UserID: 1,
}
res, err := goreq.New[placeholder]("https://jsonplaceholder.typicode.com").
	Path("/posts").BodyJson(req).IsJson().Fetch(ctx)
// net/http equivalent left as an exercise for the reader

Set custom headers for a request

// Set headers
obj, err := goreq.New[string]("https://postman-echo.com/get").
	Headers("User-Agent", "bond/james-bond",
		"Content-Type", "secret",
		"martini", "shaken").
	Fetch(ctx)

Easily manipulate URLs and query parameters

s, err := goreq.New[string]("https://prod.example.com/get?a=1&b=2").
	Params("b", "3","c", "4").Fetch(ctx)
