В этой ошибке я просто не могу найти, я читаю из файла .json db.json, обновляю json и пытаюсь записать в файл .json. Несмотря на то, что я выполняю синтаксический анализ и строковое форматирование json, я получаю эту ошибку:
SyntaxError: /Users/3x7r3m157/Development/Javascript/db.json: неожиданный конец ввода JSON
Myкод выглядит следующим образом:
const args = require('yargs').argv;
const fs = require('fs');
const util = require('util');
const leaderboard = require('./db.json')
const addCompetitor = (name) => {
leaderboard[name] = { points: [], times: [] }
console.log(leaderboard)
return leaderboard
}
console.log(leaderboard)
const addCompetitorTimes = (data) => {
console.log(data)
//this method takes a string of 'competitorName_time'
//parses it into substrings 'name' & 'time'.
//Afterwards it iterates through time in minutes and seconds as a string
//in the format of '00:00', then parses the string into substrings
//of minutes and seconds delimited by the ':' character.
//Thereafter it converts the string to integeters and converts the time
//into time in seconds for easy comparison of times.
//Finally it assigns the time to the competitor in the leaderboard and
//writes to json file db.json
let parser = 0;
var competitor = '';
let times = '';
let seconds = '';
let minutes = '';
let timeInSeconds = 0;
for (let i = 0 ; i < data.length ; i ++) {
if (parser == 0 && data[i] == '_') {
parser ++
continue
}
if (parser == 0) {
//Stack Overflow peeps, weird error right hurrr:
competitor += data[i]
}
if (parser == 1) {
times += data[i]
}
}
parser = 0
for (let i = 0 ; i < times.length ; i ++) {
if (parser == 0 && times[i] == ':') {
parser ++
continue
}
if (parser == 0) {
minutes += times[i]
}
if (parser == 1) {
seconds += times[i]
}
}
seconds = parseInt(seconds);
minutes = parseInt(minutes);
let minutesInSeconds = minutes * 60
seconds = minutesInSeconds + seconds
leaderboard[competitor].times = seconds
console.log(leaderboard)
fs.writeFileSync('./db.json', JSON.stringify(leaderboard));
return leaderboard
}
addCompetitorTimes(args.competitorTimes)
db.json:
{"Atlas":{"points":0,"times":0}}
