表妹求我写个node脚本,把java错误码表转成excel并翻译成英文

biaomei.jpg

java原始代码部分如下

public static final int ERR_ONLINE_DECLINED             = 1025;    //交易联机拒绝
    //public static final int   ERR_RESELECT_APP            = 1026; //GPO返回0x6985,重新选择应用
    public static final int ERR_OFFLINE_APPROVED            = 1027;    //交易脱机批准

需要得到的excel结果

最终采用node配合以上插件来完成，将java代码中的相关数据采集出来.

1、先安装插件

npm install node-xlsx
npm install line-reader
npm install http
npm install md5-node

2、在百度翻译api上注册一个账号 领取免费使用额度

https://ai.baidu.com/ai-doc/MT/ykqq95r2y

本来是打算用谷歌的，但最近发现谷歌的都不能访问了，知道的大佬可以告知。

注册申请了之后可以得到一个appid和对应的秘钥。

正常使用会返回翻译的结果数据如下

{
    "from": "en",
    "to": "zh",
    "trans_result": [{
        "src": "apple",
        "dst": "\u82f9\u679c" //苹果
    }]
}

3、接着编写完整node代码

//生成Excel依赖包
var xlsx = require('node-xlsx')
//写入文件依赖包
var fs = require('fs')
//一行一行读取
var lineReader = require('line-reader');
//网络请求
var http = require('http');
//md5加密
var md5 = require('md5-node');


var sheetList = []

var listCount = 0;

lineReaderTxt()


//将java文件代码的每一行读取
async function lineReaderTxt() {
    sheetList.push(['状态码', "状态值", "结果", "是否使用中", "代码行数来源"])
    var lineList = []
    var lineCount = 0
    lineReader.eachLine('PostCode.java', function(line, last) {
        lineCount += 1
        if (line.indexOf('//public static final int') != -1) {
            lineList.push(line)
        } else if (line.indexOf('public static final int') != -1) {
            lineList.push(line)
        }
        if (last) {
            console.log('最后一行了:', lineCount);
            const used = process.memoryUsage().heapUsed / 1024 / 1024;
            console.log(`The script uses approximately ${Math.round(used * 100) / 100} MB`);
            loopList(lineList)
        }
    });
}


function loopList(lineList) {
    var successCount = 0
    console.log("开始新的循环", lineList.length)
    var lineCount = 0
    lineList.forEach((line, index) => {
        if (line.indexOf('//public static final int') != -1) {
            lineCount += 1
            translateOneJavaLine(line, false, lineCount, index == (lineList.length - 1), (item) => {
                successCount += 1
                console.log("successCount1:" + successCount, "lineList:" + lineList.length)
            })
        } else if (line.indexOf('public static final int') != -1) {
            lineCount += 1
            translateOneJavaLine(line, true, lineCount, index == (lineList.length - 1), (item) => {
                successCount += 1
                console.log("successCount2:" + successCount, "lineList:" + lineList.length)
            })
        }
        if (successCount == lineList.length) {
            writeDataToExcel()
        }
    })
}


//讲数据写入excel
function writeDataToExcel() {
    console.log('写入excel前的校验', sheetList.length, listCount)
    //配置，设置列宽
    const options = {
        '!cols': [{
            wch: 30
        }, {
            wch: 10
        }, {
            wch: 50
        }, {
            wch: 20
        }, {
            wch: 20
        }]
    };
    //生成二进制数据流
    var buffer = xlsx.build([{
        name: "test",
        data: sheetList
    }], options);
    //写入文件
    fs.appendFile('./test13.xlsx', buffer, function(err) {
        if (err) {
            console.log(err, '保存excel出错')
        } else {
            console.log('写入excel成功!!!')
        }
    })
}

//提取并翻译一行的数据
function translateOneJavaLine(line, isUsed, lineNum, isLast, callback) {
    if (line.indexOf("=") != -1) {
        var itemList = []
        //校验是否有 = 符号
        var lis = line.split('=')
        const errorDaihao = lis[0].split('final int')[1].replace(/(^\s*)|(\s*$)/g, "")
        // console.log('输出的状态', errorDaihao)
        itemList.push(errorDaihao)
        const second = lis[1]
        const errorCode = second.split(';')[0].replace(/(^\s*)|(\s*$)/g, "")
        // console.log('输出的状态码', errorCode)
        itemList.push(errorCode)
        const seconds = lis[1].split(';')
        if (seconds.length > 1) {
            if (seconds[1].indexOf('//') != -1) {
                const translateSrc = seconds[1].split('//')[1].replace(/(^\s*)|(\s*$)/g, "")
                itemList.push(`${translateSrc}`)
                itemList.push(isUsed ? '是' : '否')
                itemList.push(`${lineNum}`)
                sheetList.push(itemList)
                callback(itemList)
            } else {
                itemList.push('nothing')
                itemList.push(isUsed ? '是' : '否')
                itemList.push(`${lineNum}`)
                sheetList.push(itemList)
                callback(itemList)
            }
        }
    }
}


//将中文翻译成引文 使用百度api
async function translateChineseToEnglish(keyword1) {
    var keyword = encodeURI(keyword1)
    // console.log('需要查询的数据', keyword)
    const appid = '20111008000339947'
    const secretKey = 'FGsDn1G62CdqyWVyFXQm'
    const randomStr = '1435660288'
    var params1 = `${appid}${keyword1}${randomStr}${secretKey}`
    var params2 = md5(params1)
    const baiduHost = 'http://api.fanyi.baidu.com/api/trans/vip/translate'
    let url =
        `${baiduHost}?q=${keyword}&from=zh&to=en&appid=${appid}&salt=${randomStr}&sign=${params2}`
    return new Promise((resolve) => {
        http.get(url, function(res) {
            res.setEncoding('utf8');
            var body = "";
            res.on('data', function(chunk) {
                body += chunk;
            }).on('end', function() {
                var obj = JSON.parse(body)
                if (obj.trans_result && obj.trans_result.length > 0) {
                    const result = obj.trans_result[0].dst
                    // console.log('翻译的结果是', result)
                    resolve(result)
                }
            });
        }).on('error', function(e) {
            console.log('请求报错', JSON.stringify(e))
        })
    })
}

4、执行node脚本，输出excel
