如何从google analytics多渠道渠道请求数据

Question

我可以成功地从google analytics核心报告api请求数据，但我正在努力从多渠道漏斗api中获取数据。我很确定我的问题出在权限/访问上，但是我已经看过文档了，不知道到底是什么问题。我正在使用node和googleapis库。这是我提取google分析信息的代码(这是有效的)

var {google} = require('googleapis');
var key = require('./auth.json');
var viewID = 'XXXXXXX'; 
var analytics = google.analyticsreporting('v4');
var jwtClient = new google.auth.JWT(key.client_email,
                                    null,
                                    key.private_key,
                                    ['https://www.googleapis.com/auth/analytics.readonly'],
                                    null);
jwtClient.authorize(function (err, tokens) {
  if (err) {
    console.log(err);
    return;
  } else {
    console.log('Yup, we got authorized!');
    console.log(tokens)
  }
});
  var req = {
    reportRequests: [{
      viewId: viewID,
      dateRanges: [{
        startDate: '2020-11-01',
        endDate: '2020-11-01'}],
      metrics: [{expression: 'ga:pageViews'}],
      dimensions: [{name: 'ga:city'}],
      pageSize: 10
    }],
  };
  analytics.reports.batchGet({
    auth: jwtClient,
    resource: req
  },
  function (err, response) {
    if (err) {
      console.log('Failed to get Report');
      console.log(err);
      return;
    }
    console.log('Success');
    console.log(response.data)
  }
);

这样就可以很好地生成所需的输出。我尝试更改度量和维度，以便可以提取一些我想要的多通道漏斗信息，但遇到错误

var {google} = require('googleapis');
var key = require('./auth.json');
var viewID = 'XXXXXXX'; 
var analytics = google.analyticsreporting('v4');
var jwtClient = new google.auth.JWT(key.client_email,
                                    null,
                                    key.private_key,
                                    ['https://www.googleapis.com/auth/analytics.readonly'],
                                    null);
jwtClient.authorize(function (err, tokens) {
  if (err) {
    console.log(err);
    return;
  } else {
    console.log('Yup, we got authorized!');
    console.log(tokens)
  }
});
  var req = {
    reportRequests: [{
      viewId: viewID,
      dateRanges: [{
        startDate: '2020-11-01',
        endDate: '2020-11-01'}],
      metrics: [{expression: 'mcf:sourceMedium'}],
      dimensions: [{name: 'mcf:lastInteractionConversions'}],
      pageSize: 10
    }],
  };
  analytics.reports.batchGet({
    auth: jwtClient,
    resource: req
  },
  function (err, response) {
    if (err) {
      console.log('Failed to get Report');
      console.log(err);
      return;
    }
    console.log('Success - got something back from the Googlez');
    console.log(response.data)
  }
);

它产生了这个

 code: 400,
  errors: [
    {
      message: 'Unknown dimensions(s): mcf:lastInteractionConversions, unknown metric(s): mcf:sourceMedium\n' +
        'For details see https://developers.google.com/analytics/devguides/reporting/core/dimsmets.',
      domain: 'global',
      reason: 'badRequest'
    }
  ]

我很确定我的问题要么是我的请求来源错误，要么是我的权限只适用于ga而不是mcf，但我不完全理解错误的原因或如何修复它，文档也没有提供太多帮助。任何帮助都会很感谢，谢谢。

您使用的是报告应用编程接口V4，而不是多渠道漏斗应用编程接口V3：https://developers.google.com/analytics/devguides/reporting/mcf/v3/reference

您需要的API提供了一个请求数据的方法：

analytics.data.mcf.get()
