Usage

import "github.com/winterssy/sreq"

Quick Start

The usages of sreq are very similar to net/http , you can switch from it to sreq easily. For example, if your HTTP request code like this:

resp, err := http.Get("https://www.google.com")

Use sreq you just need to change your code like this:

resp, err := sreq.Get("https://www.google.com").Raw()

You have two convenient ways to access the APIs of sreq .

const (
	url       = "http://httpbin.org/get"
	userAgent = "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/74.0.3729.169 Safari/537.36"
)

query := sreq.Params{
	"k1": "v1",
	"k2": "v2",
}

client := sreq.New()

// Go-style
req, err := sreq.NewRequest("GET", url,
	sreq.WithQuery(query),
	sreq.WithUserAgent(userAgent),
)
if err != nil {
	panic(err)
}
err = client.
	Do(req).
	EnsureStatusOk().
	Verbose(ioutil.Discard, false)
if err != nil {
	panic(err)
}

// Requests-style (Recommended)
err = client.
	Get(url,
		sreq.WithQuery(query),
		sreq.WithUserAgent(userAgent),
	).
	EnsureStatusOk().
	Verbose(os.Stdout, true)
if err != nil {
	panic(err)
}
