+# 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)
+
+Example:
+
+	// 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)
+
+
+See godoc for further documentation and examples.
