如何删除json文件中的一些不必要的空格？

Question

我是这个json和node.js的新手。现在我有json文件，其中有一些不必要的空格。如何删除？

.json文件

{
"Product_Name": "Logitech M235 Wireless Mouse (Red)",
"Brand": "Logitech",
"Color": "\n            \n                Red\n            \n        ",
"Image": "http://ecx.images-amazon.com/images/I/31UXrp3AcLL._SY300_QL70_.jpg",
"Price": "   699.00",
"Rating": "4.4 out of 5 stars"
}

颜色值包含一些空格，我不想要我只需要的空格＆＃39; Red＆＃39;。

这里我写的是json文件

server.js

var json = {Product_Name : "", Brand : "", Color : "", Image : "", Price : "", Rating : ""};

        var P_name = $('#title').children().text();
        var brand = $('#brand').text();
        var color = $('.a-row').find('span.selection').text();
        var price = $('#price').find('span.a-size-medium').text();
        var rating = $('#averageCustomerReviews').find('span.a-icon-alt').text();
        var image = $('.imgTagWrapper').children().attr('src');

        json.Product_Name = P_name;
        json.Brand = brand;
        json.Color = color;
        json.Price = price;
        json.Rating = rating;
        json.Image = image;

        fs.writeFile('output.json', JSON.stringify(json, null, 4), function(err){
            console.log('File successfully written! - Check your project directory for the output.json file');
        })

只需用颜色变量替换字符串中的空格和换行符，就像这样

color.trim()
