urllib

urllib is an libs help you to curl remote url using golang.

How to use?

Example
package main

import (
    "fmt"

    "github.com/GiterLab/urllib"
)

func main() {
    req := urllib.Get("http://tobyzxj.me/")
    req.Debug(true)
    str, err := req.String()
    if err != nil {
        fmt.Println(err)
    }
    fmt.Println(req.DumpRequestString()) // debug out
    fmt.Println(str)
}
GET

you can use Get to crawl data.

import "github.com/GiterLab/urllib"

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

POST data to remote url

req := urllib.Post("http://tobyzxj.me/")
req.Param("username","tobyzxj")
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
urllib.Get("http://tobyzxj.me/").SetTimeout(100 * time.Second, 30 * time.Second)

// POST
urllib.Post("http://tobyzxj.me/").SetTimeout(100 * time.Second, 30 * time.Second)
Debug

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

urllib.Get("http://tobyzxj.me/").Debug(true)
Set HTTP Basic Auth
str, err := Get("http://tobyzxj.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:

urllib.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

urllib.Get("http://tobyzxj.me/").SetProtocolVersion("HTTP/1.1")

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

cookie := &http.Cookie{}
cookie.Name = "username"
cookie.Value  = "tobyzxj"
urllib.Get("http://tobyzxj.me/").SetCookie(cookie)
Upload file

urllib support mutil file upload, use req.PostFile() or req.PostFileFromReader() to upload file.

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

// or
req := urllib.Post("http://tobyzxj.me/")
req.Param("username","tobyzxj")
req.PostFileFromReader("uploadfile1", "urllib.jpeg", "image/jpeg", fileReader)
str, err := req.String()
if err != nil {
    // error
}
fmt.Println(str)
