本文介绍如何使用GoHttpProMaxPlus库快速进行HTTP GET和POST操作，并演示如何通过AOP（面向切面编程）扩展功能，包括Header、Cookie、Form等。通过实例展示如何创建自定义请求和应用切面处理，让读者理解其实现原理。

goHttpProMaxPlus

Go quickly request http and Support for AOP

go快速请求Http, 同时支持AOP

要不是公司用go，我才不会写他呢！！！

以下英语均为机翻

Import dependence 导入依赖

go get github.com/971181317/goHttpProMaxPlus

Quick start 快速开始

First build a server with the gin framework

首先用gin框架搭建一个服务器

import "github.com/gin-gonic/gin"

r := gin.Default()
r.GET("/", func(c *gin.Context) {
    c.JSON(200, gin.H{
        "msg": "This is a GET method",
    })
})

r.POST("/", func(c *gin.Context) {
    c.JSON(200, gin.H{
        "msg": "This is a POST method",
    })
})

r.Run() // listen and serve on 0.0.0.0:8080

Next use goHttpProMaxPlus to quickly request Get and Post

接下来使用goHttpProMaxPlus快速请求Get和Post

import . "github.com/971181317/goHttpProMaxPlus"

resp, err := GetDefaultClient().Get("http://localhost:8080")
if err != nil {
    panic(err)
}
fmt.Println(resp.GetRespStr())

resp, err = GetDefaultClient().Post("http://localhost:8080")
if err != nil {
    panic(err)
}
fmt.Println(resp.GetRespStr())

result

结果

{"msg":"This is a GET method"}
{"msg":"This is a POST method"}

It’s pretty easy, right?

芜湖，起飞（老师，老师，我已经会get和post了）！！！

But what if you want to use Header, Cookie, or Form?

但如果想使用Header，Cookie或者Form怎么办呢？

// cookie, header, form: map[string]string
// data: *io.Reader
GetDefaultClient().GetWithCookieAndHeader(url, cookie, header)
GetDefaultClient().PostWithForm(url, form)
GetDefaultClient().PostWithCookieHeaderAndForm(url, cookie, header, form)
GetDefaultClient().PostWithIoData(url sting, data)
GetDefaultClient().PostWithCookieHeaderAndIoData(url, cookie, header, data)

AOP

5 Aspects:

BeforeClientBuild
AfterClientBuild
BeforeRequestBuild
AfterRequestBuild
AfterResponseCreate

Custom HTTP request 自定义请求

4 Steps：

create client

// AspectModel 切片模组
type AspectModel func(...interface{})

// HttpClient A client send request
type HttpClient struct {
	c                   *http.Client
	BeforeClientBuild   AspectModel
	AfterClientBuild    AspectModel
	BeforeRequestBuild  AspectModel
	AfterRequestBuild   AspectModel
	AfterResponseCreate AspectModel
	AspectArgs          []interface{} // Only the most recent assignment will be kept
}

create it and use aspect

// This method execute BeforeClientBuild and AfterClientBuild.
func NewClientX(client *http.Client,
	beforeClientBuild, afterClientBuild, beforeRequestBuild, afterRequestBuild, afterResponseCreate AspectModel,
	args ...interface{}) *HttpClient

create request

// Forms > Json > Xml > File > ReaderBody
type HttpRequest struct {
	Method     HttpMethod
	URL        string
	Cookies    map[string]string
	Headers    map[string]string
	Queries    map[string]string
	Forms      map[string]string
	Json       *string
	Xml        *string
	File       *os.File
	ReaderBody *io.Reader
}

Two types of assignment

// 1. chain
req := NewHttpRequest().
		SetMethod(POST).
		SetURL("http://localhost:8080").
		AppendHeader("header", "headerValue").
		AppendCookie("cookie", "cookieValue").
		AppendForm("form", "formValue").
		AppendQuery("query", "queryValue")

// 2.
req := &HttpRequest{
    Method     HttpMethod
	URL        "http://localhost:8080"
	Cookies    ...
	Headers    ...
	Queries    ...
	Forms      ...
    ...
}

do request

resp, err := client.Do(req)

get request body

type HttpResponse struct {
	resp    *http.Response
	Headers map[string]string
	body    io.ReadCloser
	bodyStr *string
}

func (hr *HttpResponse) ParseJson(v interface{})
func (hr *HttpResponse) GetRespStr() string
