sky_blue/request框架

A simple HTTP Request package for golang. GET POST DELETE PUT Upload

Installation

go get github.com/zdao-pro/sky_blue/pkg/net/http/request

How do we use request?
Create request object use http.DefaultTransport
req := request.NewRequest()
req := request.NewRequest().Debug(true).SetTimeout(5)
Set headers
req.SetHeaders(map[string]string{
    "Content-Type": "application/x-www-form-urlencoded",
    "Connection": "keep-alive",
})

req.SetHeaders(map[string]string{
    "Source":"api",
})
Set cookies
req.SetCookies(map[string]string{
    "name":"json",
    "token":"",
})

req.SetCookies(map[string]string{
    "age":"19",
})
Set basic auth
req.SetBasicAuth("username","password")
Set timeout
req.SetTimeout(5)  //default 30s
Transport

If you want to customize the Client object and reuse TCP connections, you need to define a global http.RoundTripper or & http.Transport, because the reuse of the http connection pool is based on Transport.

var transport *http.Transport
func init() {   
    transport = &http.Transport{
        DialContext: (&net.Dialer{
            Timeout:   30 * time.Second,
            KeepAlive: 30 * time.Second,
            DualStack: true,
        }).DialContext,
        MaxIdleConns:          100, 
        IdleConnTimeout:       90 * time.Second,
        TLSHandshakeTimeout:   5 * time.Second,
        ExpectContinueTimeout: 1 * time.Second,
    }
}

func demo(){
    // Use http.DefaultTransport
    res, err := request.Get("http://127.0.0.1:8080")
    // Use custom Transport
    res, err := request.Transport(transport).Get("http://127.0.0.1:8080")
}
Keep Alives，Only effective for custom Transport
req.DisableKeepAlives(false)

request.Transport(transport).DisableKeepAlives(false).Get("http://127.0.0.1:8080")
Ignore Https certificate validation，Only effective for custom Transport
req.SetTLSClient(&tls.Config{InsecureSkipVerify: true})

request.Transport(transport).SetTLSClient(&tls.Config{InsecureSkipVerify: true}).Get("http://127.0.0.1:8080")
Object-oriented operation mode
req := request.NewRequest().
	Debug(true).
	SetHeaders(map[string]string{
	    "Content-Type": "application/x-www-form-urlencoded",
	}).SetTimeout(5)
resp,err := req.Get("http://127.0.0.1")

resp,err := request.NewRequest().Get("http://127.0.0.1")
GET
Query parameter
resp, err := req.Get("http://127.0.0.1:8000")
resp, err := req.Get("http://127.0.0.1:8000",nil)
resp, err := req.Get("http://127.0.0.1:8000?id=10&title=request")
resp, err := req.Get("http://127.0.0.1:8000?id=10&title=request","address=beijing")

resp, err := request.Get("http://127.0.0.1:8000")
resp, err := request.Debug(true).SetHeaders(map[string]string{}).Get("http://127.0.0.1:8000")
使用配置文件

为了实现环境代码一致性,方便管理URL: 对URL的地址进行可配置管理

    1.对于http://pre.zhaodao88.com来说
      配置文件可以这样写:
      user_server:
        server:
            - pre.zhaodao88.com
        keepalive: 100`
    2.代码就得这样:
      //类似于环境变量的写法
      rs, err := r.Get("https://$user_server/user/token_check")
      //也可以直接指明地址,框架会检查
      rs, err := r.Get("https://pre.zhaodao88.com/user/token_check")

示例:

package main

import (
	"fmt"
	"github.com/zdao-pro/sky_blue/pkg/net/http/request"
)

type M map[string]Upstream

func main() {
	s := `user_server:
            server:
                - pre.zhaodao88.com
            keepalive: 100`
	request.InitUpstream(s)
	r := request.NewRequest()
	p := map[string]interface{}{
		"token": "eee",
	}
	rs, err := r.Get("https://$user_server/user/token_check", p)
	if err != nil {
		panic(err)
	}
	fmt.Println(rs.Content())
}
Multi parameter

    "name":  "jason",
    "score": 100,
