试图获取联赛统计数据来计算主场比赛的胜率

Question

我一直在尝试使用riot games api来计算之前的所有自定义游戏，然后为单个玩家找到输赢连胜，我构建了以下代码来为特定用户获取比赛。

请参阅https://github.com/FriendlyUser/deno-riot-games-custom-games

但我觉得暴乱游戏api只会在第11季之前返回v4 api的数据，如果有人能澄清api的工作原理或解释我如何获得更多数据，那将是非常棒的。

import { writeJson } from "https://deno.land/std/fs/mod.ts"
import "https://deno.land/x/dotenv/load.ts"
const player_id = Deno.env.get('ACCOUNT_ID')
const region_url = 'https://na1.api.riotgames.com'
let riot_URL = new URL(`${region_url}/lol/match/v4/matchlists/by-account/${player_id}`)
enum HTTP {
GET = 'GET',
POST = 'POST',
PUT = 'PUT',
DELETE = 'DELETE'
}
interface MatchlistDto {
startIndex: number
totalGames: number
endIndex: number
matches: Array<any>
}
function makeFetchOptions(
riotKey = Deno.env.get('RIOT_API_KEY'),
method: HTTP = HTTP.GET
): object {
return {
method: method,
headers: { 
"Accept-Charset": "application/x-www-form-urlencoded; charset=UTF-8",
"Accept-Language":  "en-US,en;q=0.9",
'X-Riot-Token': riotKey
}
}
}
function appendMatchHistory(riot_endpoint: string): Promise<MatchlistDto> {
const riotKey = Deno.env.get('RIOT_API_KEY')
console.log(riotKey)
const options = makeFetchOptions(riotKey)
return fetch(riot_endpoint, options)
.then( (resp: any) => {
console.log(resp)
return resp.json() 
})
.then( (matchData: MatchlistDto) => {
return matchData
})
}
const max_iterations = 1000
let bIndex = 0
let eIndex = 100
let current_url = riot_URL
let riot_endpoint = null
let allMatches = []
let customGames = []
const sleep = (milliseconds: number) => {
return new Promise(resolve => setTimeout(resolve, milliseconds))
}
for (let i = 0; i < max_iterations; i++) {
console.log(`beginIndex: ${bIndex} endIndex: ${eIndex}`)
riot_endpoint = current_url.toString()
const newMatches = await appendMatchHistory(riot_endpoint)
await sleep(1500)
current_url.searchParams.delete('beginIndex')
current_url.searchParams.delete('endIndex')
const {matches} = newMatches
if (matches.length == 0) {
console.log(`ENDING SCRIPT AT ${eIndex} with ${matches.length}`)
break
}
// startIndex becomes endIndex
bIndex = eIndex
eIndex = eIndex + 100
allMatches.push(newMatches.matches)
// get new url
current_url.searchParams.append('beginIndex', String(bIndex))
current_url.searchParams.append('endIndex', String(eIndex))
}
await writeJson(
"./allData.json",
allMatches
);

如果这个答案迟了，很抱歉。但是，是的，Riot API仅用于；当前"；数据，这就是为什么像U.GG、OP.GG等网站实际上运行脚本来连续存储数据的原因。因此，为了获得统计数据，您必须编写脚本，以便随着时间的推移将其存储到自己的数据库中。

遗憾的是，无法获得上一季的数据
