gbk转utf8

gbk转utf8的库

gopm get -g -v golang.org/x/text
gopm get -g -v golang.org/x/net/html

mahonia 库

go get github.com/axgle/mahonia

• 然后新建一个 func
• src 字符串
• srcCode 字符串当前编码
• tagCode 要转换的编码

func ConvertToString(src string, srcCode string, tagCode string) string {
    srcCoder := mahonia.NewDecoder(srcCode)
    srcResult := srcCoder.ConvertString(src)
    tagCoder := mahonia.NewDecoder(tagCode)
    _, cdata, _ := tagCoder.Translate([]byte(srcResult), true)
    result := string(cdata)
    return result
}

例子1：

调用 ConvertToString 方法

str := "乱码的字符串变量"
str  = ConvertToString(str, "gbk", "utf-8")
fmt.Println(str)

例子2：

package main
 
import (
    "code.google.com/p/mahonia"
    "fmt"
)
 
func main() {
    //"你好，世界！"的GBK编码
    testBytes := []byte{0xC4, 0xE3, 0xBA, 0xC3, 0xA3, 0xAC, 0xCA, 0xC0, 0xBD, 0xE7, 0xA3, 0xA1}
    var testStr string
    utfStr := "你好，世界！"
    var dec mahonia.Decoder
    var enc mahonia.Encoder
 
    testStr = string(testBytes)
 
    dec = mahonia.NewDecoder("gbk")
    if ret, ok := dec.ConvertStringOK(testStr); ok {
        fmt.Println("GBK to UTF-8: ", ret, " bytes:", testBytes)
    }
 
    enc = mahonia.NewEncoder("gbk")
    if ret, ok := enc.ConvertStringOK(utfStr); ok {
        fmt.Println("UTF-8 to GBK: ", ret, " bytes: ", []byte(ret))
    }
    return
}
