节点:通过服务帐户的Google Analytics数据

Question

更新:我已经将代码转换为NPM模块.

我一直在为服务帐户创建一个JWT令牌,我可以访问用户数据,但我想获取我的分析数据,用它来驱动我网站上的内容.

注意:我不知道是否有比这更好的方法,但现有的npm工具似乎要求您输入密码.结果我最终使用REST调用而不是gapi工具.

这是我得到的错误

{ error: 
   { errors: [ [Object] ],
     code: 403,
     message: 'User does not have any Google Analytics account.' } }

这是我正在使用的代码,用于处理用户数据.

var oauth2Client = new OAuth2(CLIENT_ID, CLIENT_SECRET, REDIRECT_URL);

var scopes = [
  'https://www.googleapis.com/auth/plus.me',
  'https://www.googleapis.com/auth/analytics.readonly'
];

var d = new Date();
var seconds = d.getTime() / 1000 + 60*59;

var SERVICE_CLIENT_ID = "xxxxxxx-0h21osagsg02eqk45me6ts7jn3kf0vfr.apps.googleusercontent.com";
var SERVICE_EMAIL     = "xxxxxxx-0h21osagsg02eqk45me6ts7jn3kf0vfr@developer.gserviceaccount.com"

var claim_set = {
    "iss": SERVICE_EMAIL,
    "scope": 'https://www.googleapis.com/auth/analytics.readonly',
    "aud": 'https://www.googleapis.com/oauth2/v3/token',
    "exp":seconds,
    "iat":seconds
};

var algorithm = {"alg":"RS256","typ":"JWT"};
var private_key = fs.readFileSync('privatekey.pem');

var signature = jwt.sign(claim_set, private_key, { algorithm: algorithm.alg});

var post_obj = {
    grant_type: "urn:ietf:params:oauth:grant-type:jwt-bearer",
    assertion: signature
};

request.post({
    url:'https://www.googleapis.com/oauth2/v3/token',
    form: post_obj
}, function(err, data) {
    if (err) throw err;
    var body = JSON.parse(data.body);
    var token = body.access_token;
    // console.log(token);
    console.log("Token: ",token);


    var auth_obj = {
        'auth': {
            'bearer': token
        }
    };
    // THIS CODE DOES RETURN INFORMATION
    // request.get('https://www.googleapis.com/plus/v1/people/me', auth_obj, function(err, data) {
    //  if (err) throw err;
    //  console.log(JSON.parse(data.body));
    // });

    var report = {
        'ids': 'ga:78624107',
        'start-date': '2014-10-01',
        'end-date': '2014-12-31',
        'metrics': 'ga:sessions,ga:bounces'
    };
    var report2 = 'metrics=ga%253Ausers&start-date=2015-02-24&end-date=2015-03-10&max-results=50'
    var report3 = 'ids=ga:78624107&start-date=2015-02-24&end-date=2015-03-10&metrics=ga:users'

    request.get('https://www.googleapis.com/analytics/v3/data/ga?'+report3, auth_obj, function(err, data) {
        if (err) throw err;
        console.log(JSON.parse(data.body));
    });
});

默认情况下,服务帐户没有Google Analytics帐户.

进入Google Analytics网站,管理部分将该服务帐户电子邮件地址添加为该ACCOUNT级别的用户,它必须位于帐户级别.然后,服务帐户将有权读取您的Google分析数据.
