封装Apk签名工具

将android apk签名的的方式封装成一个工具，通过SignConfig.json配置文件相关参数签名apk。
golang 实现代码

package main

import (
    "io/ioutil"
    "encoding/json"
    "fmt"
    "github.com/yanghai23/GoLib/atfile"
    "os/exec"
    "time"
)

var ip, whoami []byte
var err error
var cmd *exec.Cmd
var status = false

func main() {
    data, err := readConfig()
    if err != nil {
        return
    }
    res := config2Obj(data)

    //jarsigner -verbose -keystore foyoos.keystore
    // -storepass foyoosgame
    // -signedjar sign.apk %1 foyoos.keystore
    // -digestalg SHA1
    // -sigalg MD5withRSA
    go wait()
    camd := fmt.Sprintf("jarsigner -verbose  -keystore %s -keypass %s -storepass %s -signedjar %s %s %s -digestalg SHA1 -sigalg MD5withRSA",
        res.StoreFile,
        res.KeyPassword,
        res.StorePassword,
        res.TargetAppName,
        res.SourceAppName,
        res.KeyAlias)
    fmt.Println("请稍等，每个小点为表示1s，一排60个小点")
    fmt.Println(camd)

    cmd = exec.Command("jarsigner",
        "-verbose",
        "-keystore", res.StoreFile,
        "-keypass", res.KeyPassword,
        "-storepass", res.StorePassword,
        "-signedjar", res.TargetAppName, res.SourceAppName,
        res.KeyAlias,
        "-digestalg", "SHA1",
        "-sigalg", "MD5withRSA")
    status = true
    if whoami, err = cmd.Output(); err != nil {
        fmt.Println(err)
    }
    // 默认输出有一个换行
    fmt.Println(string(whoami))
}

func config2Obj(data []byte) *Config {
    config := &Config{}
    json.Unmarshal(data, config)
    return config
}

/**
    读取配置
 */

func readConfig() (data []byte, err error) {
    currentPath := atfile.GetCurrentDirectory()
    data, err = ioutil.ReadFile(currentPath + "/SignConfig.json")
    if err != nil {
        fmt.Println("err = ", err)
    }
    return data, err
}

/**
    创建结构体
 */

type Config struct {
    KeyAlias      string `json:keyAlias`
    KeyPassword   string `json:keyPassword`
    StoreFile     string `json:storeFile`
    StorePassword string `json:storePassword`
    TargetAppName string `json:targetAppName`
    SourceAppName string `json:sourceAppName`
}

func wait() {

    t := 0
    for ; !status; {
        time.Sleep(time.Second)
        t ++
        if t < 60 {
            fmt.Print(".")
        } else {
            t = 0
            fmt.Println(".")
        }
    }
}

配置文件
{
"keyAlias": "xxxx.keystore",
"keyPassword": "xxxx",
"storeFile": "~/xxxx.keystore",
"storePassword": "xxx",
"sourceAppName": "./xxxx_sign.apk",
"targetAppName": "./sign.apk"
}

注：

1. 需要签名的apk需要和程序放在同一目录
2. 签名后的apk需要放在跟程序同一目录下
3. 配置文件必须和程序放在同一个目录
