Parsed http response body in json format

package main

import (
	"fmt"
	"github.com/guonaihong/gout"
)

type rsp struct {
	ErrMsg  string `json:"errmsg"`
	ErrCode int    `json:"errcode"`

	if err != nil {
		fmt.Printf("err = %v\n", err)
	}
}

yaml

SetYAML() 设置请求http body为yaml
BindYAML() 解析响应http body里面的yaml到结构体里面

发送yaml到服务端，然后把服务端返回的yaml结果解析到结构体里面

type data struct {
    Id int `yaml:"id"`
    Data string `yaml:"data"`
}


var d1, d2 data
var httpCode int 


err := gout.POST(":8080/test.yaml").SetYAML(&d1).BindYAML(&d2).Code(&httpCode).Do()
if err != nil || httpCode != 200{
    fmt.Printf("send fail:%s\n", err)
}

xml

SetXML() 设置请求http body为xml
BindXML() 解析响应http body里面的xml到结构体里面

发送xml到服务端，然后把服务端返回的xml结果解析到结构体里面

type data struct {
    Id int `xml:"id"`
    Data string `xml:"data"`
}


var d1, d2 data
var httpCode int 


err := gout.POST(":8080/test.xml").SetXML(&d1).BindXML(&d2).Code(&httpCode).Do()
if err != nil || httpCode != 200{
    fmt.Printf("send fail:%s\n", err)
}

form-data

SetForm() 设置http body 为multipart/form-data格式数据

客户端发送multipart/form-data到服务端,curl用法等同go代码

curl -F mode=A -F text="good" -F voice=@./test.pcm -f voice2=@./test2.pcm url

使用gout.H

package main

import (
	"fmt"
	"github.com/guonaihong/gout"
)

func main() {

	code := 0
	err := gout.
		POST(":8080/test").
		// 打开debug模式
		Debug(true).
		SetForm(
			gout.H{
				"mode": "A",
				"text": "good",
				// 从文件里面打开
				"voice":  gout.FormFile("test.pcm"),
				"voice2": gout.FormMem("pcm"),
			},
		).
		//解析http code，如不关心可以不设置
		Code(&code).
		Do()

	if err != nil {
		fmt.Printf("%s\n", err)
	}

	if code != 200 {
	}
}

使用结构体

type testForm struct {
    Mode string `form:"mode"`
    Text string `form:"text"`
    Voice string `form:"voice" form-file:"true"` //从文件中读取 
    Voice2 []byte `form:"voice2" form-file:"mem"`  //从内存中构造
}

type rsp struct{
    ErrMsg string `json:"errmsg"`
    ErrCode int `json:"errcode"`
}

t := testForm{}
r := rsp{}
code := 0

err := gout.POST(url).SetForm(&t).ShoudBindJSON(&r).Code(&code).Do()
if err != nil {

}

x-www-form-urlencoded

使用SetWWWForm函数实现发送x-www-form-urlencoded类型数据

package main

import (
	"fmt"
	"github.com/guonaihong/gout"
)

func main() {

	code := 0
	err := gout.
		POST(":8080/post").
		// 打开debug模式
		Debug(true).
		// 设置x-www-form-urlencoded数据
		SetWWWForm(
			gout.H{
				"int":     3,
				"float64": 3.14,
				"string":  "test-www-Form",
			},
		).
		// 关心http code 返回值设置
		Code(&code).
		Do()
	if err != nil {
		fmt.Printf("%s\n", err)
		return
	}

	if code != 200 {
	}
}

/*

float64=3.14&int=3&string=test-www-Form

< HTTP/1.1 200 OK
< Content-Length: 0

*/

protobuf

SetProtoBuf支持，protobuf序列化后的[]byte，或者生成的protobuf结构体指针

package main

import (
	"github.com/guonaihong/gout"
)

func main() {
	httpCode := 0
	err := GET(":8080/echo").
		SetProtoBuf( /* protobuf 生成的结构体，必须传指针类型*/ ).
		Code(&httpCode).
		Do()
}

callback

callback主要用在，服务端会返回多种格式body的场景, 比如404返回的是html, 200返回json。这时候要用Callback挂载多种处理函数，处理不同的数据结构


func main() {
	
	r, str404 := Result{}, ""
	code := 0

	err := gout.GET(":8080").Callback(func(c *gout.Context) (err error) {

		switch c.Code {
		case 200: //http code为200时，服务端返回的是json 结构
			c.BindJSON(&r)
		case 404: //http code为404时，服务端返回是html 字符串
			c.BindBody(&str404)
		}
		code = c.Code
		return nil

	}).Do()

	if err != nil {
		fmt.Printf("err = %s\n", err)
		return
	}

	fmt.Printf("http code = %d, str404(%s) or json result(%v)\n", code, str404, r)

}

get .Response

func main() {
	

	resp, err := gout.GET(":8080").SetJSON(`{"test":"value"}`).Response()

	if resp != nil {
		defer resp.Body.Close()
	}
}

Set request timeout

setimeout是request级别的超时方案。相比http.Client级别，更灵活。

package main

import (
	"fmt"
	"github.com/guonaihong/gout"
	"time"
)

func main() {
	err := gout.GET(":8080").
		SetTimeout(2 * time.Second).
		Do()

	if err != nil {
		fmt.Printf("err = %v\n", err)
	}
}

proxy

SetProxy 设置代理服务地址

package main

import (
	"fmt"
	"github.com/guonaihong/gout"
	"log"
)

func main() {
	c := &http.Client{}
	s := ""
	err := gout.
		New(c).
		GET("www.qq.com").
		// 设置proxy服务地址
		SetProxy("http://127.0.0.1:7000").
		// 绑定返回数据到s里面
		BindBody(&s).
		Do()

	if err != nil {
		log.Println(err)
		return
	}

	fmt.Println(s)
}

socks5

SetSOCKS5 设置socks5地址

package main

import (
    "fmt"
    "github.com/guonaihong/gout"
    "log"
    "net/http"
)

func main() {
    c := &http.Client{}
    s := ""
    err := gout.
        New(c).
        GET("www.qq.com").
        // 设置proxy服务地址
        SetSOCKS5("127.0.0.1:7000").
        // 绑定返回数据到s里面
        BindBody(&s).
        Do()

    if err != nil {
        log.Println(err)
        return
    }   

    fmt.Println(s)
}

SetCookies设置cookie, 可以设置一个或者多个cookie

package main

import (
	"fmt"
	"github.com/guonaihong/gout"
	"net/http"
)

func main() {

	// === 发送多个cookie ====
	err := gout.
		// :8080/cookie是http://127.0.0.1:8080/cookie的简写
		GET(":8080/cookie").
		//设置debug模式
		Debug(true).
		SetCookies(
			//设置cookie1
			&http.Cookie{
				Name:  "test1",
				Value: "test1",
			},
			//设置cookie2
			&http.Cookie{
				Name:  "test2",
				Value: "test2",
			},
		).
		Do()

	if err != nil {
		fmt.Println(err)
		return
	}

	// === 发送一个cookie ===
	err = gout.
		// :8080/cookie/one是http://127.0.0.1:8080/cookie/one的简写
		GET(":8080/cookie/one").
		//设置debug模式
		Debug(true).
		SetCookies(
			//设置cookie1
			&http.Cookie{
				Name:  "test3",
				Value: "test3",
			},
		).
		Do()
	fmt.Println(err)

}

basic auth

使用SetBasicAuth接口

func main() {
	
	err := gout.POST(":8080/colorjson").
		SetBasicAuth("userName", "password").
		SetJSON(gout.H{"str": "foo",
			"num":   100,
			"bool":  false,
			"null":  nil,
			"array": gout.A{"foo", "bar", "baz"},
			"obj":   gout.H{"a": 1, "b": 2},
		}).Do()

	if err != nil {
		fmt.Printf("err = %v\n", err)
	}
}

context

WithContext设置context，可以取消http请求

Cancel a sending request

package main

import (
    "context"
    "github.com/guonaihong/gout"
    "time"
)

func main() {
    //　声明一个context
    ctx, cancel := context.WithCancel(context.Background())

    //调用cancel可取消http请求
    go func() {
        time.Sleep(time.Second)
        cancel()
    }() 

    err := gout.
        GET("127.0.0.1:8080/cancel"). //设置GET请求以及需要访问的url
        WithContext(ctx).             //设置context, 外层调用cancel函数就可取消这个http请求
        Do()

    if err != nil {
    }   
}

unix socket

UnixSocket可以把http底层通信链路由tcp修改为unix domain socket
下面的例子，会通过domain socket发送http GET请求，http body的内容是hello world

package main

import (
    "fmt"
    "github.com/guonaihong/gout"
    "net/http"
)

func main() {
    c := http.Client{}

    g := gout.
        New(&c).
        UnixSocket("/tmp/test.socket") //设置unixsocket文件位置

    err := g.
        GET("http://a/test").   //设置GET请求
        SetBody("hello world"). //设置body内容
        Do()
    fmt.Println(err)
}

http2 doc

go 使用https访问http2的服务会自动启用http2协议，这里不需要任何特殊处理

https://http2.golang.org/ (bradfitz建的http2测试网址,里面大约有十来个测试地址，下面的例子选了一个)

package main

import (
    "fmt"
    "github.com/guonaihong/gout"
)

func main() {
    s := ""
    err := gout.
        GET("https://http2.golang.org/reqinfo"). //设置GET请求和请求url
        Debug(true).                             //打开debug模式，可以看到请求数据和响应数据
        SetBody("hello, ###########").           //设置请求body的内容，如果你的请求内容是json格式，需要使用SetJSON函数
        BindBody(&s).                            //解析响应body内容
        Do()                                     //结束函数

    if err != nil {
        fmt.Printf("send fail:%s\n", err)
    }   
    _ = s 
}

debug mode

Turn on debug mode

该模式主要方便调试用的，默认开启颜色高亮(如果要关闭颜色高亮，请往下看)

func main() {
	
	err := gout.POST(":8080/colorjson").
		Debug(true). //打开debug模式
		SetJSON(gout.H{"str": "foo",
			"num":   100,
			"bool":  false,
			"null":  nil,
			"array": gout.A{"foo", "bar", "baz"},
			"obj":   gout.H{"a": 1, "b": 2},
		}).Do()

	if err != nil {
		fmt.Printf("err = %v\n", err)
	}
}

Turn off color highlighting in debug mode

使用gout.NoColor()传入Debug函数关闭颜色高亮

func main() {
	
	err := gout.POST(":8080/colorjson").
		Debug(gout.NoColor()).
		SetJSON(gout.H{"str": "foo",
			"num":   100,
			"bool":  false,
			"null":  nil,
			"array": gout.A{"foo", "bar", "baz"},
			"obj":   gout.H{"a": 1, "b": 2},
		}).Do()

	if err != nil {
		fmt.Printf("err = %v\n", err)
	}
}

Custom debug mode

debug 自定义模式，可传递函数。下面演示用环境变量开启debug模式(只有传递IOS_DEBUG环境变量才输出日志)

package main

import (
    "fmt"
    "github.com/guonaihong/gout"
    "os"
)

func IOSDebug() gout.DebugOpt {
    return gout.DebugFunc(func(o *gout.DebugOption) {
        if len(os.Getenv("IOS_DEBUG")) > 0 { 
            o.Debug = true
        }
    })  
}

func main() {

    s := ""
    err := gout.
        GET("127.0.0.1:8080").
        // Debug可以支持自定义方法
        // 可以实现设置某个环境变量才输出debug信息
        // 或者debug信息保存到文件里面，可以看下_example/15-debug-save-file.go
        Debug(IOSDebug()).
        SetBody("test hello").
        BindBody(&s).
        Do()

    fmt.Printf("err = %v\n", err)
}

// env IOS_DEBUG=true go run customize.go

trace info

gout.Trace()可输出http各个阶段的耗时，比如dns lookup时间，tcp连接时间等等。可以很方便的做些性能调优。

package main

import (
    "fmt"
    "github.com/guonaihong/gout"
)

func openDebugTrace() {
    err := gout.POST(":8080/colorjson").
        Debug(gout.Trace()).
        SetJSON(gout.H{"str": "foo",
            "num":   100,
            "bool":  false,
            "null":  nil,
            "array": gout.A{"foo", "bar", "baz"},
            "obj":   gout.H{"a": 1, "b": 2},
        }).Do()

    if err != nil {
        fmt.Printf("err = %v\n", err)
    }
}

output

=================== Trace Info(S): ===================
     DnsDuration           : 0s
     ConnDuration          : 868.623µs

benchmark

benchmarking a certain number of times

下面的例子，起了20并发。对:8080端口的服务，发送3000次请求进行压测，内容为json结构

package main

import (
	"fmt"
	"github.com/guonaihong/gout"
)

const (
	benchNumber     = 30000
	benchConcurrent = 20
)

func main() {
	err := gout.
		POST(":8080").                     //压测本地8080端口
		SetJSON(gout.H{"hello": "world"}). //设置请求body内容
		Filter().                          //打开过滤器
		Bench().                           //选择bench功能
		Concurrent(benchConcurrent).       //并发数
		Number(benchNumber).               //压测次数
		Do()

	if err != nil {
		fmt.Printf("%v\n", err)
	}
}

benchmark-duration

下面的例子，起了20并发。对:8080端口的服务，压测持续时间为10s，内容为json结构

package main

import (
	"fmt"
	"github.com/guonaihong/gout"
	"time"
)

const (
	benchTime       = 10 * time.Second
	benchConcurrent = 30
)

func main() {
	err := gout.
		POST(":8080").                     //压测本机8080端口
		SetJSON(gout.H{"hello": "world"}). //设置请求body内容
		Filter().                          //打开过滤器
		Bench().                           //选择bench功能
		Concurrent(benchConcurrent).       //并发数
		Durations(benchTime).              //压测时间
		Do()

	if err != nil {
		fmt.Printf("%v\n", err)
	}
}

benchmark-rate

下面的例子，起了20并发。对:8080端口的服务，压测总次数为3000次，其中每秒发送1000次。内容为json结构

package main

import (
	"fmt"
	"github.com/guonaihong/gout"
)

const (
	benchNumber     = 3000
	benchConcurrent = 20
)

func main() {
	err := gout.
		POST(":8080").                     //压测本机8080端口
		SetJSON(gout.H{"hello": "world"}). //设置请求body内容
		Filter().                          //打开过滤器
		Bench().                           //选择bench功能
		Rate(1000).                        //每秒发1000请求
		Concurrent(benchConcurrent).       //并发数
		Number(benchNumber).               //压测次数
		Do()

	if err != nil {
		fmt.Printf("%v\n", err)
	}
}

Custom benchmark functions

自定义压测函数，构造每次不一样的http request数据

package main

import (
    "fmt"
    "github.com/google/uuid"
    "github.com/guonaihong/gout"
    "github.com/guonaihong/gout/filter"
    "sync/atomic"
)

func main() {
    i := int32(0)

    err := filter.NewBench().
        Concurrent(30). //开30个go程
        Number(30000).  //压测30000次
        Loop(func(c *gout.Context) error {

			// 下面的代码，每次生成不一样的http body 用于压测
            uid := uuid.New()  //生成uuid
            id := atomic.AddInt32(&i, 1) //生成id, 可以理解为++i，线程安全版本

            c.POST(":1234").SetJSON(gout.H{"sid": uid.String(),
                "appkey": fmt.Sprintf("ak:%d", id),
                "text":   fmt.Sprintf("test text :%d", id)})
            return nil

        }).Do()

    if err != nil {
        fmt.Printf("err = %v\n", err)
    }
}

retry-backoff

retry 功能使用带抖动功能和指数回退的算法实现backoff

package main

import (
	"fmt"
	"github.com/guonaihong/gout"
	"time"
)

func main() {
	err := gout.HEAD("127.0.0.1:8080").
		Debug(true).                      //打开debug模式
		Filter().                         //打开过滤器
		Retry().                          //打开重试模式
		Attempt(5).                       //最多重试5次
		WaitTime(500 * time.Millisecond). //基本等待时间
		MaxWaitTime(3 * time.Second).     //最长等待时间
		Do()

	if err != nil {
		fmt.Printf("err = %v\n", err)
	}
}

retry conditions httpcode

指定重试条件，这里面的例子是服务端返回的状态码是209进行重试完整代码

package main

import (
	"fmt"
	"github.com/guonaihong/gout"
	"github.com/guonaihong/gout/filter"
	"time"
)

func useRetryFuncCode() {
	s := ""
	err := gout.GET(":8080/code").Debug(true).BindBody(&s).F().
		Retry().Attempt(3).WaitTime(time.Millisecond * 10).MaxWaitTime(time.Millisecond * 50).
		Func(func(c *gout.Context) error {
			if c.Error != nil || c.Code == 209 {
				return filter.ErrRetry
			}

			return nil

		}).Do()

	fmt.Printf("err = %v\n", err)
}

retry conditions backupurl

指定条件进行重试，这里的例子是默认url不能访问，使用backup url进行访问完整代码

package main

import (
	"fmt"
	"github.com/guonaihong/gout"
	"github.com/guonaihong/gout/core"
	"github.com/guonaihong/gout/filter"
	"time"
)
func useRetryFunc() {
	// 获取一个没有服务绑定的端口
	port := core.GetNoPortExists()
	s := ""

	err := gout.GET(":" + port).Debug(true).BindBody(&s).F().
		Retry().Attempt(3).WaitTime(time.Millisecond * 10).MaxWaitTime(time.Millisecond * 50).
		Func(func(c *gout.Context) error {
			if c.Error != nil {
				c.SetHost(":1234") //必须是存在的端口
				return filter.ErrRetry
			}
			return nil

		}).Do()
	fmt.Printf("err = %v\n", err)
}

import

send raw http request

package main

import (
    "fmt"
    "github.com/guonaihong/gout"
)

func main() {
	s := `POST /colorjson HTTP/1.1
Host: 127.0.0.1:8080
User-Agent: Go-http-client/1.1
Content-Length: 97
Content-Type: application/json
Accept-Encoding: gzip

{"array":["foo","bar","baz"],"bool":false,"null":null,"num":100,"obj":{"a":1,"b":2},"str":"foo"}
    `
	err := gout.NewImport().RawText(s).Debug(true).SetHost(":1234").Do()
	if err != nil {
		fmt.Printf("err = %s\n", err)
		return
	}
}

export

generate curl command

package main

import (
    "fmt"
    "github.com/guonaihong/gout"
)

func main() {
    // 1.formdata
    err := gout.GET(":1234").
        SetForm(gout.A{"text", "good", "mode", "A", "voice", gout.FormFile("./t8.go")}).
        Export().Curl().Do()
    // output:
    // curl -X GET -F "text=good" -F "mode=A" -F "voice=@./voice" "http://127.0.0.1:1234"

    // 2.json body
    err = gout.GET(":1234").
        SetJSON(gout.H{"key1": "val1", "key2": "val2"}).
        Export().Curl().Do()
    // output:
    // curl -X GET -H "Content-Type:application/json" -d "{\"key1\":\"val1\",\"key2\":\"val2\"}" "http://127.0.0.1:1234"

    fmt.Printf("%v\n", err)
}

Incoming custom *http.Client

使用New接口即可使用自己的http.Client对象

package main

import (
	"fmt"
	"net/http"

	"github.com/guonaihong/gout"
)

func main() {

	c := &http.Client{} //http.Client里面有fd连接池，如果对这块优化不是太了解，只使用一个实例就行
	err := gout.New(c). // New接口可传入http.Client对象
				GET("www.qq.com").
				Debug(true).
				Do()

	if err != nil {
		fmt.Printf("err = %s\n", err)
		return
	}
}

Using chunked data format

使用Chunked接口, 设置为"Transfer-Encoding: chunked"的数据编码方式

package main

import (
        "fmt"

        "github.com/guonaihong/gout"
)

func main() {
        err := gout.POST(":8080").
                Chunked().
                SetBody("11111111111").
                Do()
        if err != nil {
                fmt.Printf("err :%v\n", err)
        }   
}
// 使用nc 起一个tcp服务, 使用上面的代码发起数据观察下结果
// nc -l 8080

NewWithOpt

这里记录全局配置的方法, 后面所有的全局配置都推荐使用gout.NewWithOpt接口的实现

insecure skip verify

忽略ssl验证, 使用gout.WithInsecureSkipVerify()接口配置该功能, 传入gout.NewWithOpt接口即可生效.

import (
	"github.com/guonaihong/gout"
)

func main() {
	// globalWithOpt里面包含连接池, 这是一个全局可复用的对象
	globalWithOpt := gout.NewWithOpt(gout.WithInsecureSkipVerify())
	err := globalWithOpt.GET("url").Do()
	if err != nil {
		fmt.Printf("err = %v\n" ,err)
		return
	}
}

Turn off 3xx status code automatic jump

golang client库默认遇到301的状态码会自动跳转重新发起新请求, 你希望关闭这种默认形为, 那就使用下面的功能

import (
	"github.com/guonaihong/gout"
)

func main() {
	// globalWithOpt里面包含连接池, 这是一个全局可复用的对象, 一个进程里面可能只需创建1个
	globalWithOpt := gout.NewWithOpt(gout.WithClose3xxJump())
	err := globalWithOpt.GET("url").Do()
	if err != nil {
		fmt.Printf("err = %v\n" ,err)
		return
	}
}

NewWithOpt set timeout

gout.WithTimeout 为了让大家少用gout.SetTimeout而设计

import (
	"github.com/guonaihong/gout"
)

func main() {
	// globalWithOpt里面包含连接池, 这是一个全局可复用的对象, 一个进程里面可能只需创建1个
	globalWithOpt := gout.NewWithOpt(gout.WithTimeout())
	err := globalWithOpt.GET("url").Do()
	if err != nil {
		fmt.Printf("err = %v\n" ,err)
		return
	}
}

Global configuration

set timeout

设置全局超时时间。可以简化一些代码。在使用全局配置默认你已经了解它会带来的一些弊端.


package main

import (
	"fmt"
	"github.com/guonaihong/gout"
	"time"
)

func main() {
	gout.SetTimeout(time.Second * 1)
	err := gout.GET("www.baidu.com").Do()
	if err != nil {
		fmt.Printf("err is:%v\n")
	}
}

Unique features

forward gin data

gout 设计之初就考虑到要和gin协同工作的可能性，下面展示如何方便地使用gout转发gin绑定的数据。

package main

import (
	"github.com/gin-gonic/gin"
	"github.com/guonaihong/gout"
)

type testQuery struct {
	Size int    `query:"size" form:"size"` // query tag是gout设置查询字符串需要的
	Page int    `query:"page" form:"page"`
	Ak   string `query:"ak" form:"ak"`
}

//下一个服务节点
func nextSever() {
	r := gin.Default()

	r.GET("/query", func(c *gin.Context) {
		q := testQuery{}
		err := c.ShouldBindQuery(&q)
		if err != nil {
			return
		}
		c.JSON(200, q)
	})
	r.Run(":1234")
}

func main() {
	go nextSever()
	r := gin.Default()

	// 演示把gin绑定到的查询字符串转发到nextServer节点
	r.GET("/query", func(c *gin.Context) {
		q := testQuery{}
		// 绑定查询字符串
		err := c.ShouldBindQuery(&q)
		if err != nil {
			return
		}

		// 开发转发, 复用gin所用结构体变量q
		code := 0 // http code
		err := gout.
			//发起GET请求
			GET("127.0.0.1:1234/query").
			//设置查询字符串
			SetQuery(q).
			//关心http server返回的状态码 设置该函数
			Code(&code).
			Do()
		if err != nil || code != 200 { /* todo Need to handle errors here */
		}
		c.JSON(200, q)
	})

	r.Run()
}

// http client
// curl '127.0.0.1:8080/query?size=10&page=20&ak=test'
