zhttp

zhttp 是一个对 net/http 标准库的封装，参考了 python 中著名的 requests 库，支持标准库中的连接池，支持dns缓存，支持流式文件上传，支持多种body格式，很多代码及思路来自grequests

Installation

go get github.com/greyh4t/zhttp

Usage

直接使用默认client

import "github.com/greyh4t/zhttp"

func main() {
	resp, err := zhttp.Get("http://www.example.com/", nil)
	if err != nil {
		return
	}
	resp.Close()
}

更改默认client配置

import "github.com/greyh4t/zhttp"

func main() {
	zhttp.InitDefaultClient(&zhttp.HTTPOptions{
		Proxies: zhttp.MustProxy(zhttp.M{
			"http":  "http://127.0.0.1:8080",
			"https": "http://127.0.0.1:8080",
		}),
	})

	resp, err := zhttp.Get("http://www.example.com/", nil)
	if err != nil {
		return
	}
	resp.Close()
}

创建独立的client使用

import "github.com/greyh4t/zhttp"

func main() {
	z := zhttp.New(&zhttp.HTTPOptions{
		Proxies: zhttp.MustProxy(zhttp.M{
			"http":  "http://127.0.0.1:8080",
			"https": "http://127.0.0.1:8080",
		}),
	})

	resp, err := z.Get("http://www.example.com/", nil)
	if err != nil {
		return
	}
	resp.Close()
}
