Functions

func EncodeBase64

func EncodeBase64(msg string) string

func Errorf

func Errorf(format string, v ...interface{})

func GetConf

func GetConf(filename string) (map[string][]string, error)

读取配置文件

Example

package main

import (
	"fmt"
	"github.com/watsonserve/goutils"
)

func main() {
	// # test.conf
	// # this is a config file
	// foo = bar
	// foos=1
	// foos = 2
	// null
	//
	conf, err := goutils.GetConf("test.conf")
	if nil != err {
		return
	}
	fmt.Println(conf)
}

Output:
{ foo: ["bar"], foos: ["1", "2"], null: [] }

func GetOptions

func GetOptions(options []Option) (map[string]string, []string)

解析命令行参数

Example

package main

import (
	"fmt"
	"github.com/watsonserve/goutils"
)

func main() {
	options := []goutils.Option{
		{
			Opt:       'h',
			Option:    "help",
			HasParams: false,
		},
		{
			Opt:       'z',
			Option:    "gz",
			HasParams: false,
		},
		{
			Opt:       'C',
			Option:    "cc",
			HasParams: true,
		},
		{
			Opt:       'f',
			Option:    "file",
			HasParams: true,
		},
	}
	argMap, params := goutils.GetOptions(options)

	fmt.Println(argMap)
	fmt.Println(params)
}

func TLSSocket

func TLSSocket(port string, crt string, key string) (net.Listener, error)

* 这里使用的是每个链接启动一个新的go程的模型 * 高并发的话，性能取决于go语言的协程能力
