Youtube Analytics - 創建請求

我正在嘗試向YouTube分析API發出請求。並且在形成請求時遇到一些麻煩，所以他們被接受。我使用的是谷歌的API Node.js的客戶Youtube Analytics - 創建請求

https://github.com/google/google-api-nodejs-client

，我的代碼如下

import { Meteor } from 'meteor/meteor'; 
import google from 'googleapis'; 
import KEY_FILE from './keyFile.json'; 
import { CHANNEL_ID } from './channelId.js'; 

//api's 
const analytics = google.youtubeAnalytics('v1'); 

//fetch youtube analytics 
export function youtubeAnalytics(start, end){ 
    //initalise request data 
    const startDate = `${start.getFullYear()}-${('0'+(start.getMonth()+1)).slice(-2)}-${('0'+(start.getDate())).slice(-2)}`; 
    const endDate = `${end.getFullYear()}-${('0'+(end.getMonth()+1)).slice(-2)}-${('0'+(end.getDate())).slice(-2)}`; 
    const scopes = [ 
    'https://www.googleapis.com/auth/youtube', 
    'https://www.googleapis.com/auth/youtube.readonly', 
    'https://www.googleapis.com/auth/yt-analytics-monetary.readonly', 
    'https://www.googleapis.com/auth/yt-analytics-monetary.readonly' 
    ]; 

    //generate authorisation token 
    var AUTH = new google.auth.JWT(
    KEY_FILE.client_email, 
    null, 
    KEY_FILE.private_key, 
    scopes, 
    null 
    ); 

    //authorize request 
    AUTH.authorize(function (err, tokens) { 
    if (err) { 
     console.log(err); 
     return; 
    } 

    //create request 
    const analyticsRequest = { 
     auth: AUTH, 
     'start-date': startDate, 
     'end-date': endDate, 
     ids: `channel==${CHANNEL_ID}`, 
     metrics: 'views', 
    }; 

    //make request 
    analytics.reports.query(analyticsRequest, function (err, data) { 
     if (err) { 
     console.error('Error: ' + err); 
     return false; 
     } 
     if (data) { 
     console.log(data); 
     return data; 
     } 
    }); 
    }); 
    return false; 
} 

Meteor.methods({youtubeAnalytics});

我不斷收到以下錯誤

Error: Error: Invalid query. Query did not conform to the expectations.

我認爲它做與我的要求對象

const analyticsRequest = { 
    auth: AUTH, 
    'start-date': startDate, 
    'end-date': endDate, 
    ids: `channel==${CHANNEL_ID}`, 
    metrics: 'views', 
};

但我發現的所有例子都說這個請求對象應該工作。我儘可能地簡化了它。我原來的要求（我真正想要的那個）如下。

const analyticsRequest = { 
    auth: AUTH, 
    'start-date': startDate, 
    'end-date': endDate, 
    ids: `channel==${CHANNEL_ID}`, 
    metrics: 'views', 
    dimensions: 'video', 
    sort: '-views', 
    'max-results': '200' 
}

後，我需要做的另一個請求得到它使用不同的API端點列出的影片的所有相關信息。

//api's 
const youtube = google.youtube('v3'); 

/* 
    do processing of analytics data to create batchRequest 
    which is a string of comma separated video ids 
*/ 

videoRequest = { 
    auth: AUTH, 
    part: 'id,snippet', 
    id: batchRequest; 
} 

youtubeApiData.search.list(videosRequest, function (err, data) { 
    if (err) { 
     console.error('Error: ' + err); 
     return false; 
    } 
    if (data) { 
     console.log(data); 
     return data; 
    } 
});

因此，在總結

我需要做不同的谷歌API的請求，並讓他們接受我有麻煩形成請求（我還沒有過去YouTube數據分析的第一個請求）。

有人能指出我正確的方向嗎？

想通了。無法爲此API做一個服務帳戶請求。通過我的設置帳戶驗證帳戶，谷歌

https://guide.meteor.com/accounts.html

使用賬戶合併合併它的基本帳戶

https://atmospherejs.com/splendido/accounts-meld

，給了我連接到用戶，然後做了OAuth的一個訪問令牌2.0改爲撥打。爲facebook做了類似的事情。

我仍然存在的一個問題是'視頻的抓取保留'部分超級低效。它爲每個視頻撥打一個電話。有批量的請求可用於谷歌的API，但我似乎無法找到一個正確的例子使用'谷歌'的包。如果有人有一個例子，將不勝感激。

這裏是新的代碼。

    const analytics = {views: [], retention: []}; 
    const videos = []; 

    const startDate = `${start.getFullYear()}-${('0'+(start.getMonth()+1)).slice(-2)}-${('0'+(start.getDate())).slice(-2)}`; 
    const endDate = `${end.getFullYear()}-${('0'+(end.getMonth()+1)).slice(-2)}-${('0'+(end.getDate())).slice(-2)}`;
