Documentation

Full documentation is available on the official website: https://req.cool.

Features

  • Simple and Powerful: Simple and easy to use, providing rich client-level and request-level settings, all of which are intuitive and chainable methods.
  • Easy Debugging: Powerful and convenient debug utilities, including debug logs, performance traces, and even dump the complete request and response content (see Debugging).
  • Easy API Testing: API testing can be done with minimal code, no need to explicitly create any Request or Client, or even to handle errors (See Quick HTTP Test)
  • Smart by Default: Detect and decode to utf-8 automatically if possible to avoid garbled characters (See Auto Decode), marshal request body and unmarshal response body automatically according to the Content-Type.
  • Support Multiple HTTP Versions: Support HTTP/1.1, HTTP/2, and HTTP/3, and can automatically detect the server side and select the optimal HTTP version for requests, you can also force the protocol if you want (See Force HTTP version).
  • Support Retry: Support automatic request retry and is fully customizable (See Retry).
  • HTTP Fingerprinting: Support http fingerprint impersonation, so that we can access websites that prohibit crawler programs by identifying http fingerprints (See HTTP Fingerprint).
  • Multiple Authentication Methods: You can use HTTP Basic Auth, Bearer Auth Token and Digest Auth out of box (see Authentication).
  • Easy Download and Upload: You can download and upload files with simple request settings, and even set a callback to show real-time progress (See Download and Upload).
  • Exportable: req.Transport is exportable. Compared with http.Transport, it also supports HTTP3, dump content, middleware, etc. It can directly replace the Transport of http.Client in existing projects, and obtain more powerful functions with minimal code change.
  • Extensible: Support Middleware for Request, Response, Client and Transport (See Request and Response Middleware) and Client and Transport Middleware).

Get Started

Install

You first need Go installed (version 1.20+ is required), then you can use the below Go command to install req:

go get github.com/imfantuan/req/v3

Import

Import req to your code:

import "github.com/imfantuan/req/v3"

Basic Usage

# assume the following codes in main.go file
$ cat main.go

package main

import (
    "github.com/imfantuan/req/v3"
)

func main() {
    req.DevMode() // Treat the package name as a Client, enable development mode
    req.MustGet("https://httpbin.org/uuid") // Treat the package name as a Request, send GET request.

    req.EnableForceHTTP1() // Force using HTTP/1.1
    req.MustGet("https://httpbin.org/uuid")
}

$ go run main.go

The sample code above is good for quick testing purposes, which use DevMode() to see request details, and send requests using global wrapper methods that use the default client behind the scenes to initiate the request.

In production, it is recommended to explicitly create a client, and then use the same client to send all requests, please see other examples below.

Simple GET

package main

import (
	"fmt"
	"github.com/imfantuan/req/v3"
	"log"
)

func main() {
	client := req.C() // Use C() to create a client.
	resp, err := client.R(). // Use R() to create a request.
		Get("https://httpbin.org/uuid")
	if err != nil {
		log.Fatal(err)
	}
	fmt.Println(resp)
}

{
  "uuid": "a4d4430d-0e5f-412f-88f5-722d84bc2a62"
}

Advanced GET

package main

import (
  "fmt"
  "github.com/imfantuan/req/v3"
  "log"
  "time"
)

type ErrorMessage struct {
  Message string `json:"message"`
}

type UserInfo struct {
  Name string `json:"name"`
  Blog string `json:"blog"`
}

func main() {
  client := req.C().
    SetUserAgent("my-custom-client"). // Chainable client settings.
    SetTimeout(5 * time.Second)

  var userInfo UserInfo
  var errMsg ErrorMessage
  resp, err := client.R().
    SetHeader("Accept", "application/vnd.github.v3+json"). // Chainable request settings.
    SetPathParam("username", "imroc"). // Replace path variable in url.
    SetSuccessResult(&userInfo). // Unmarshal response body into userInfo automatically if status code is between 200 and 299.
    SetErrorResult(&errMsg). // Unmarshal response body into errMsg automatically if status code >= 400.
    EnableDump(). // Enable dump at request level, only print dump content if there is an error or some unknown situation occurs to help troubleshoot.
    Get("https://api.github.com/users/{username}")

  if err != nil { // Error handling.
    log.Println("error:", err)
    log.Println("raw content:")
    log.Println(resp.Dump()) // Record raw content when error occurs.
    return
  }

  if resp.IsErrorState() { // Status code >= 400.
    fmt.Println(errMsg.Message) // Record error message returned.
    return
  }

  if resp.IsSuccessState() { // Status code is between 200 and 299.
    fmt.Printf("%s (%s)\n", userInfo.Name, userInfo.Blog)
    return
  }

  // Unknown status code.
  log.Println("unknown status", resp.Status)
  log.Println("raw content:")
  log.Println(resp.Dump()) // Record raw content when server returned unknown status code.
}

Normally it will output (SuccessState):

roc (https://imroc.cc)

More Advanced GET

You can set up a unified logic for error handling on the client, so that each time you send a request you only need to focus on the success situation, reducing duplicate code.

package main

import (
	"fmt"
	"github.com/imfantuan/req/v3"
	"log"
	"time"
)

type ErrorMessage struct {
	Message string `json:"message"`
}

func (msg *ErrorMessage) Error() string {
	return fmt.Sprintf("API Error: %s", msg.Message)
}

type UserInfo struct {
	Name string `json:"name"`
	Blog string `json:"blog"`
}

var client = req.C().
	SetUserAgent("my-custom-client"). // Chainable client settings.
	SetTimeout(5 * time.Second).
	EnableDumpEachRequest().
	SetCommonErrorResult(&ErrorMessage{}).
	OnAfterResponse(func(client *req.Client, resp *req.Response) error {
		if resp.Err != nil { // There is an underlying error, e.g. network error or unmarshal error.
			return nil
		}
		if errMsg, ok := resp.ErrorResult().(*ErrorMessage); ok {
			resp.Err = errMsg // Convert api error into go error
			return nil
		}
		if !resp.IsSuccessState() {
			// Neither a success response nor a error response, record details to help troubleshooting
			resp.Err = fmt.Errorf("bad status: %s\nraw content:\n%s", resp.Status, resp.Dump())
		}
		return nil
	})

func main() {
	var userInfo UserInfo
	resp, err := client.R().
		SetHeader("Accept", "application/vnd.github.v3+json"). // Chainable request settings
		SetPathParam("username", "imroc").
		SetSuccessResult(&userInfo). // Unmarshal response body into userInfo automatically if status code is between 200 and 299.
		Get("https://api.github.com/users/{username}")

	if err != nil { // Error handling.
		log.Println("error:", err)
		return
	}

	if resp.IsSuccessState() { // Status code is between 200 and 299.
		fmt.Printf("%s (%s)\n", userInfo.Name, userInfo.Blog)
	}
}

Do API Style

If you like, you can also use a Do API style like the following to make requests:

package main

import (
	"fmt"
	"github.com/imfantuan/req/v3"
)

type APIResponse struct {
	Origin string `json:"origin"`
	Url    string `json:"url"`
}

func main() {
	var resp APIResponse
	c := req.C().SetBaseURL("https://httpbin.org/post")
	err := c.Post().
		SetBody("hello").
		Do().
		Into(&resp)
	if err != nil {
		panic(err)
	}
	fmt.Println("My IP is", resp.Origin)
}

My IP is 182.138.155.113
  • The order of chain calls is more intuitive: first call Client to create a request with a specified Method, then use chain calls to set the request, then use Do() to fire the request, return Response, and finally call Response.Into to unmarshal response body into specified object.
  • Response.Into will return an error if an error occurs during sending the request or during unmarshalling.
  • The url of some APIs is fixed, and different types of requests are implemented by passing different bodies. In this scenario, Client.SetBaseURL can be used to set a unified url, and there is no need to set the url for each request when initiating a request. Of course, you can also call Request.SetURL to set it if you need it.

Build SDK With Req

Here is an example of building GitHub's SDK with req, using two styles (GetUserProfile_Style1, GetUserProfile_Style2).

import (
	"context"
	"fmt"
	"github.com/imfantuan/req/v3"
)

type ErrorMessage struct {
	Message string `json:"message"`
}

// Error implements go error interface.
func (msg *ErrorMessage) Error() string {
	return fmt.Sprintf("API Error: %s", msg.Message)
}

type GithubClient struct {
	*req.Client
}

func NewGithubClient() *GithubClient {
	return &GithubClient{
		Client: req.C().
			SetBaseURL("https://api.github.com").
			SetCommonErrorResult(&ErrorMessage{}).
			EnableDumpEachRequest().
			OnAfterResponse(func(client *req.Client, resp *req.Response) error {
				if resp.Err != nil { // There is an underlying error, e.g. network error or unmarshal error.
					return nil
				}
				if errMsg, ok := resp.ErrorResult().(*ErrorMessage); ok {
					resp.Err = errMsg // Convert api error into go error
					return nil
				}
				if !resp.IsSuccessState() {
					// Neither a success response nor a error response, record details to help troubleshooting
					resp.Err = fmt.Errorf("bad status: %s\nraw content:\n%s", resp.Status, resp.Dump())
				}
				return nil
			}),
	}
}

type UserProfile struct {
	Name string `json:"name"`
	Blog string `json:"blog"`
}

// GetUserProfile_Style1 returns the user profile for the specified user.
// Github API doc: https://docs.github.com/en/rest/users/users#get-a-user
func (c *GithubClient) GetUserProfile_Style1(ctx context.Context, username string) (user *UserProfile, err error) {
	_, err = c.R().
		SetContext(ctx).
		SetPathParam("username", username).
		SetSuccessResult(&user).
		Get("/users/{username}")
	return
}

// GetUserProfile_Style2 returns the user profile for the specified user.
// Github API doc: https://docs.github.com/en/rest/users/users#get-a-user
func (c *GithubClient) GetUserProfile_Style2(ctx context.Context, username string) (user *UserProfile, err error) {
	err = c.Get("/users/{username}").
		SetPathParam("username", username).
		Do(ctx).
		Into(&user)
	return
}

const (
	// HeaderOderKey is the key of header order, which specifies the order
	// of the http header.
	HeaderOderKey = "__header_order__"
	// PseudoHeaderOderKey is the key of pseudo header order, which specifies

var NoBody = noBody{}

NoBody is an io.ReadCloser with no bytes. Read always returns EOF and Close always returns nil. It can be used in an outgoing client request to explicitly signal that a request has zero bytes. An alternative, however, is to simply set Request.Body to nil.

type Transport 

type Transport struct {
	Headers http.Header
	Cookies []*http.Cookie

	transport.Options
	// contains filtered or unexported fields
}

Transport is an implementation of http.RoundTripper that supports HTTP, HTTPS, and HTTP proxies (for either HTTP or HTTPS with CONNECT).

By default, Transport caches connections for future re-use. This may leave many open connections when accessing many hosts. This behavior can be managed using Transport's CloseIdleConnections method and the MaxIdleConnsPerHost and DisableKeepAlives fields.

Transports should be reused instead of created as needed. Transports are safe for concurrent use by multiple goroutines.

A Transport is a low-level primitive for making HTTP and HTTPS requests. For high-level functionality, such as cookies and redirects, see Client.

Transport uses HTTP/1.1 for HTTP URLs and either HTTP/1.1 or HTTP/2 for HTTPS URLs, depending on whether the server supports HTTP/2, and how the Transport is configured. The DefaultTransport supports HTTP/2. To explicitly enable HTTP/2 on a transport, use golang.org/x/net/http2 and call ConfigureTransport. See the package docs for more about HTTP/2.

Responses with status codes in the 1xx range are either handled automatically (100 expect-continue) or ignored. The one exception is HTTP status code 101 (Switching Protocols), which is considered a terminal status and returned by RoundTrip. To see the ignored 1xx responses, use the httptrace trace package's ClientTrace.Got1xxResponse.

Transport only retries a request upon encountering a network error if the request is idempotent and either has no body or has its Request.GetBody defined. HTTP requests are considered idempotent if they have HTTP methods GET, HEAD, OPTIONS, or TRACE; or if their Header map contains an "Idempotency-Key" or "X-Idempotency-Key" entry. If the idempotency key value is a zero-length slice, the request is treated as idempotent but the header is not sent on the wire.
