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
