How to use gclient

go get github.com/jianzhiyao/gclient

Client

New a client

cli := gclient.New(
		//with context
		gclient.OptContext(context.Background()),
		//set timeout
		gclient.OptTimeout(3*time.Second),
		//retry if get error after requesting
		gclient.OptRetry(3),
		//enable compression: br
		gclient.OptEnableBr(),
		//enable compression: gzip
		gclient.OptEnableGzip(),
		//enable compression: deflate
		gclient.OptEnableDeflate(),
		//set header for client level
		gclient.OptHeader("token", "request_token"),
		gclient.OptHeaders(map[string][]string{
			`accept-language`: []string{
				`zh-CN`,
				`zh;q=0.9`,
				`en;q=0.8`,
				`en-US;q=0.7`,
			},
		}),
		//set cookie jar for http.Client
		gclient.OptCookieJar(nil),
		//set transport for http.Client
		gclient.OptTransport(nil),
	)

Request

Simple request

cli := gclient.New()
if resp, err := cli.Do(http.MethodHead, "http://exmaple.com/job.json"); err != nil {
	fmt.Println(err)
} else {
	fmt.Println(resp.String())
}

Complex request

supported methods

• NewRequest
• NewRequestGet
• NewRequestHead
• NewRequestPost
• NewRequestPut
• NewRequestPatch
• NewRequestDelete
• NewRequestConnect
• NewRequestOptions
• NewRequestTrace

if req, err := gclient.NewRequest(http.MethodGet, "https://exmaple.com"); err != nil {
	fmt.Println(err)
	} else {
	var data Data
	if err := req.Json(&Data{}); err != nil {
		fmt.Println(err)
	} else {
		resp, err := cli.DoRequest(req)
	}
}

Response

Status

fmt.Println(resp.Status())
fmt.Println(resp.StatusCode())

Body

Get response content as string

if body, err := resp.String(); err != nil {
	fmt.Println(err)
} else {
	fmt.Println(body)
}

Get response content as []byte

if body, err := resp.Bytes(); err != nil {
	fmt.Println(err)
} else {
	fmt.Println(body)
}

Unmarshal response content as json

var a Resp
if err := resp.JsonUnmarshal(&a); err != nil {
	fmt.Println(err)
} else {
	fmt.Println(a)
}

Unmarshal response content as yaml

var a Resp
if err := resp.YamlUnmarshal(&a); err != nil {
	fmt.Println(err)
} else {
	fmt.Println(a)
}

Unmarshal response content as xml

var a Resp
if err := resp.XmlUnmarshal(&a); err != nil {
	fmt.Println(err)
} else {
	fmt.Println(a)
}
