Nodejs的模版中有很多关于Excel表格的，这里我简单介绍一下我使用过的一个模块的使用。
首先，先安装Excel的模块:
npm install node-xlsx
然后，在代码中引入模块：
var xlsx = require('node-xlsx');
最后，获取数据并写入Excel：
var fs = require('fs'); var xlsx = require('node-xlsx'); var ajax = require('./ajax.js'); start(); function start() { ajax.ajax({ url: "http://yuntuapi.amap.com/datamanage/data/list", type: "GET", data: { tableid: "XXX",//53eacbe4e4b0693fbf5fd13b key: "XXX" }, success: function (data) { var myDatas = []; var datas = (JSON.parse(data)).datas; var count = 0; for (var index in datas) { var account = datas[index]; var colum = []; var names; if (index == 0) { names = []; } for (var index2 in account) { if (index == 0) names.push(index2); var value = account[index2]; if (value == null) { value = ""; } colum.push(value); // console.log(account); } if (index == 0) { myDatas.push(names); } myDatas.push(colum); if (index == datas.length - 1) { writeXls(myDatas); } } console.log(myDatas.length); } }); } function writeXls(datas) { var buffer = xlsx.build({worksheets: [ {"name": "Group", "data": datas} ]}); fs.writeFileSync("Group.csv", buffer, 'binary'); } function parseXls() { var obj = xlsx.parse('myFile.xlsx'); console.log(obj); }
Ajax 部分的代码：
var https = require("https"); var http = require("http"); var Url = require("url"); var querystring = require('querystring'); // 默认值 var defaultSetting = { // 如果返回false可以取消本次请求 beforeSend: function (req) { }, complete: function (req) { }, data: '', // Object, String dataType: 'JSON', error: function () { }, headers: {}, // {k:v, ...} statusCode: {}, success: function (data) { }, timeout: 10, type: 'GET', // GET, POST url: "www.baidu.com" }; /** * */ function ajax(settings) { // ajaxlbs.js(settings) if (typeof settings === "object") { // 处理默认值继承 // todo ... for (key in defaultSetting) { if (settings[key] == null) { settings[key] = defaultSetting[key]; } } } var params = Url.parse(settings.url, true); // params 解析出来的参数如下 // { // "protocol":"http:", // "slashes":true, // "host":"localhost:3000", // "port":"3000", // "hostname":"localhost", // "href":"http://localhost:3000/"search":""query":{"d":"1"}, // "pathname":"/", // "path":"/" // } var options = { host: params.hostname, port: params.port || 80, path: params.path, method: settings.type }; if (settings.data != null) { options.path += "" for (var key in settings.data) { options.path = options.path + "&" + key + "=" + settings.data[key]; } console.log(options.path); } var httpUnity = http; if (params.protocol == "https:") { options.port = 443; var httpUnity = https; } var req = httpUnity.request(options,function (res) { var data = ''; res.on('data',function (chunk) { data += chunk; }).on('end', function () { if (settings.dataType === "json") { try { data = JSON.parse(data); } catch (e) { data = null; } } settings.success(data); settings.complete(req); }); }).on('error', function (e) { settings.error(e); }); // if (typeof settings.beforeSend === "function") { // if (!settings.beforeSend(req)) { // settings.complete(req); // req.end(); // return false; // } // } if (settings.type === "POST") { var dataStr = querystring.stringify(settings.data); req.setHeader("Content-Length", dataStr.length); req.write(dataStr); } req.setTimeout(settings.timeout); req.end(); } exports.ajax = ajax;
