原生JS获取cookie并转换成json

原生获取cookie

var cookieString = document.cookie;

 原生获取的cookie转换为JSON的方法

1.原始转换

function cookie_to_json(){
    var cookie_text = document.cookie;
    var arr = [];
    var text_to_split = cookie_text.split(";");
    for(var i in text_to_split){
        var tmp = text_to_split[i].split("=");
        arr.push('"'+tmp.shift().trim()+'":"'+tmp.join(":").trim()+'"')
    };
    var res ='{\n'+arr.join(",\n")+'\n}';
    return JSON.parse(res);
}
console.log(cookie_to_json());

2.原始转换和编码后的汉字解码

function cookie_to_json(decode){
    if (decode==undefined) {
        var cookie_text = document.cookie;
    } else {
        var cookie_text = decodeURIComponent(decodeURI(document.cookie));
    }
    var arr = [];
    var text_to_split = cookie_text.split(";");
    for(var i in text_to_split){
        var tmp = text_to_split[i].split("=");
        arr.push('"'+tmp.shift().trim()+'":"'+tmp.join(":").trim()+'"')
    };
    var res ='{\n'+arr.join(",\n")+'\n}';
    return JSON.parse(res);
}
 
//不做decode编码转换,原始输出；
 
console.log(cookie_to_json());
 
//编码转换，一般用于cookie中的某些内容转换成中文
console.log(cookie_to_json(1));
