JS |从JSON文件中获取价格

Question

所以我试图匹配我的JSON文件中的market_hash_name，然后获取值price，但我遇到了JSON文件的问题。我正在尝试循环它，但我收到length未定义的错误。在data.prices.length

这是我的功能

function fixItems(items){
    var fixeditems = [];
    fs.readFile('prices.json', 'utf8', function(err, data){
        if(err){
            console.log(err);
        }
        for(var i in items.itemsToReceive){
            for(var k = 0; k < data.prices.length; k++){
                if(items.itemsToReceive[i].market_hash_name == data.prices[k].market_hash_name){
                    console.log(data.prices[k].price);
                }
            }
        }
    });
    return fixeditems;
}

调用函数

console.log(fixItems(JSON.parse('{"partner":{"universe":1,"type":1,"instance":1,"accountid":212532673},"id":"1929552531","message":"Your deposit for CSGOParmud has been sent.
