httplib

httplib is an libs help you to curl remote url.

How to use?

GET

you can use Get to crawl data.

import "github.com/astaxie/beego/httplib"

str, err := httplib.Get("http://beego.me/").String()
if err != nil {
    	// error
}
fmt.Println(str)

POST

POST data to remote url

req := httplib.Post("http://beego.me/")
req.Param("username","astaxie")
req.Param("password","123456")
str, err := req.String()
if err != nil {
    	// error
}
fmt.Println(str)

Set timeout

The default timeout is 60 seconds, function prototype:

SetTimeout(connectTimeout, readWriteTimeout time.Duration)

Exmaple:

// GET
httplib.Get("http://beego.me/").SetTimeout(100 * time.Second, 30 * time.Second)

// POST
httplib.Post("http://beego.me/").SetTimeout(100 * time.Second, 30 * time.Second)

Debug

If you want to debug the request info, set the debug on

httplib.Get("http://beego.me/").Debug(true)

Set HTTP Basic Auth

str, err := Get("http://beego.me/").SetBasicAuth("user", "passwd").String()
if err != nil {
    	// error
}
fmt.Println(str)

Set HTTPS

If request url is https, You can set the client support TSL:

httplib.SetTLSClientConfig(&tls.Config{InsecureSkipVerify: true})

More info about the tls.Config please visit http://golang.org/pkg/crypto/tls/#Config

Set HTTP Version

some servers need to specify the protocol version of HTTP

httplib.Get("http://beego.me/").SetProtocolVersion("HTTP/1.1")

Set Cookie

some http request need setcookie. So set it like this:

cookie := &http.Cookie{}
cookie.Name = "username"
cookie.Value  = "astaxie"
httplib.Get("http://beego.me/").SetCookie(cookie)

Upload file

httplib support mutil file upload, use req.PostFile()

req := httplib.Post("http://beego.me/")
req.Param("username","astaxie")
req.PostFile("uploadfile1", "httplib.pdf")
str, err := req.String()
if err != nil {
    	// error
}
fmt.Println(str)

Overview

Usage:

import "github.com/astaxie/beego/httplib"

	b := httplib.Post("http://beego.me/")
	b.Param("username","astaxie")
	b.Param("password","123456")
	b.PostFile("uploadfile1", "httplib.pdf")
	b.PostFile("uploadfile2", "httplib.txt")
	str, err := b.String()
	if err != nil {
		t.Fatal(err)
	}
	fmt.Println(str)

Types

type BeegoHttpRequest

type BeegoHttpRequest struct {
	// contains filtered or unexported fields
}

BeegoHttpRequest provides more useful methods for requesting one url than http.Request.

func Delete

func Delete(url string) *BeegoHttpRequest

Delete returns *BeegoHttpRequest DELETE method.

func Get

func Get(url string) *BeegoHttpRequest

Get returns *BeegoHttpRequest with GET method.
