伙计们,我在我的nodejs应用程序中遇到此错误,但我不明白错误是什么,以及' forEach'是什么问题。 TypeError:无法读取属性' forEach'未定义的,
var request = require('request');
var log4js = require('log4js');
var logger = log4js.getLogger();
var fs = require('fs');
var prices;
setInterval(function(){
request('https://api.csgofast.com/price/all', function(error, response, body) {
prices = JSON.parse(body);
var newprice = JSON.parse('{"response":{"success":1,"current_time":1464567644,"items":{}}}');
prices.prices.forEach(function(item) {
newprice.response.items['migration_time_validation'] = JSON.stringify(database_params);
newprice.response.items[item.market_hash_name] = {
"value": item.price
}
});
fs.writeFileSync('C:/Program Files (x86)/Ampps/www/test/prices.txt', body);
logger.trace('New prices loaded.');
});
}, 3);
答案 0 :(得分:0)
prices.prices
未定义。但是,您可以尝试将响应/数据存储在prices.txt
Array.from(prices).forEach(function(item){...};
