nodejs读取服务器json文件,nodejs读写json文件的简单方法(必看)

nodejs 读json文件

var fs=reauire('fs');

var file="d:\0.json";

var result=JSON.parse(fs.readFileSync( file));

nodejs 写json文件

var coors = {};

coors.left_top = {};

coors.right_top = {};

coors.left_bottom = {};

coors.right_bottom = {};

//填充coors中内容

var filename = "d:\coors\0.json";

fs.writeFileSync(filename, JSON.stringify(coors));

//对象嵌套

var fs = require('fs');

var fileDirectory = "D:\column";

var newfileDirectory = "d:\new";

if (fs.existsSync(fileDirectory)) {

var files = fs.readdirSync(fileDirectory);

for (var i = 0; i < files.length; i++) {

var filePath = fileDirectory + "/" + files[i];

var newfilepath = newfileDirectory + "/" + files[i]

var filestr = JSON.parse(fs.readFileSync(filePath));

for (var item in filestr) {

var inter=filestr[item];

for(var m in inter)

{

inter[m]=parseFloat(inter[m]);

}

fs.writeFileSync(newfilepath, JSON.stringify(filestr));

}

}

} else {

console.log(fileDirectory + " Not Found!");

}
