Go：UTF8与GBK转换

Go默认是UTF8编码

1.GBK转UTF8

1.1.文件树形图

demo
├── gbk.txt
└── text_test.go

1.2.代码

gbk.txt

注意使用GBK编码

中国

text_test.go

package main

import (
    "bytes"
    "golang.org/x/text/encoding/simplifiedchinese"
    "golang.org/x/text/transform"
    "io/ioutil"
    "testing"
)

func TestGBK(t *testing.T) {
    data, err := ioutil.ReadFile("gbk.txt")
    if err != nil {
        t.Fatal(err)
    }
    // 打印GBK
    t.Log(string(data))

    // GBK转UTF8
    data, err = ioutil.ReadAll(transform.NewReader(bytes.NewBuffer(data), simplifiedchinese.GBK.NewDecoder()))
    if err != nil {
        t.Fatal(err)
    }

    // 打印UTF8
    t.Log(string(data))
}

1.3.测试

=== RUN   TestGBK
    text_test.go:17: �й�
    text_test.go:26: 中国
--- PASS: TestGBK (0.00s)
PASS

2.UTF8转GBK

2.1.文件树形图

demo
├── utf8.txt
└── text_test.go

2.2.代码

utf8.txt

注意使用utf8编码

中国

text_test.go

package main

import (
    "bytes"
    "golang.org/x/text/encoding/simplifiedchinese"
    "golang.org/x/text/transform"
    "io/ioutil"
    "testing"
)

func TestUTF8(t *testing.T) {
    data, err := ioutil.ReadFile("utf8.txt")
    if err != nil {
        t.Fatal(err)
    }
    // 打印UTF8
    t.Log(string(data))

    // UTF8转GBK
    data, err = ioutil.ReadAll(transform.NewReader(bytes.NewBuffer(data), simplifiedchinese.GBK.NewEncoder()))
    if err != nil {
        t.Fatal(err)
    }

    // 打印GBK
    t.Log(string(data))
}

2.3.测试

=== RUN   TestUTF8
    text_test.go:17: 中国
    text_test.go:26: �й�
--- PASS: TestUTF8 (0.00s)
PASS
