如何在R

Question

根据手册，我不知道如何使用body向Google API建立请求： https://developers.google.com/my-business/content/insight-data https://cloud.google.com/blog/products/maps-platform/introducing-insights-in-google-my

简单的请求有效，但我不知道如何编写正文部分（如上述url）。

{
  "locationNames": [
    “accounts/account_name/locations/locationId”,
  ],
  “basicRequest” : {
          "metricRequests": [
             {
               "metric": QUERIES_DIRECT,
             },
             {
               "metric": QUERIES_INDIRECT,
             }
          ],
          "timeRange": {
               "startTime": 2016-10-12T01:01:23.045123456Z,
               "endTime": 2017-01-10T23:59:59.045123456Z,
          },
    },
}

insights.url = paste0('https://mybusiness.googleapis.com/v4/',account.id,'/locations:reportInsights')

req <- POST(
  url = insights.url,
  body = toJSON(args, auto_unbox=TRUE),
  add_headers(Authorization = paste("Bearer", token, sep = " "))
)
