node.js – 响应sendgrid nodejs Api时未获得的总项数

`var request = sg.emptyRequest()
  request.queryParams["page"] = '1'
  request.queryParams["page_size"] = '1'
  request.queryParams["list_id"] = '1'
  request.method = 'GET'
  request.path = '/v3/contactdb/lists/{list_id}/recipients'
  sg.API(request, function (error, response) {
    console.log(response.statusCode)
    console.log(response.body)
    console.log(response.headers)
  });`

这是我的Api回应： –

i am calling reciepents list by list id.
pagination is working in this Api but i am not getting total items params in response.

GET /v3/contactdb/lists/{list_id}

例如：

var request = sg.emptyRequest();

request.queryParams["list_id"] = '1';
request.method = 'GET';
request.path = '/v3/contactdb/lists/{list_id}';

sg.API(request, function(error, response) {
  console.log(response.statusCode);
  console.log(response.body);
  console.log(response.body.id); // The list id
  console.log(response.body.name); // The list name
  console.log(response.body.recipient_count); // The count of all recipients of this list
  console.log(response.headers);
});
