如何从Ticketmaster的开放API获取所有事件数据？

Question

我正在尝试从Ticketmaster的API获取所有事件信息，并将特定变量添加到mongoDB。但是，我目前使用的API限制为每页200个事件。因此，我无法将事件信息与场地信息相关联，因为这些信息单独添加到mongoDB中。一种解决方案可能是通过更改API-url中的页面参数来遍历所有页面，或者可能还有其他选项？

我的代码看起来像这样（抱歉长度......）：

app.get('/tm', (req, res) => {
  axios // getting venues
    .get('https://app.ticketmaster.com/discovery/v2/venues.json?apikey=myApiKey&page=0&size=200&countryCode=DK')
    .then(response => {
      const venuesToBeInserted = response.data._embedded.venues.map(venue => { // preparing venues
        return {
          sourceID: venue.id,
          venue: venue.name,
          postalCode: venue.postalCode,
          city: venue.city.name,
          country: venue.country.name,
          countryCode: venue.country.countryCode,
          address: !!venue.address ? venue.address.line1 : null,
          longitude: !!venue.location ? venue.location.longitude : null,
          latitude: !!venue.location ? venue.location.latitude : null,
          source: 'ticketmaster'
        }
      })

      // Create all venues at once
      Venue.create(venuesToBeInserted).then(venues => {
        console.log("venues inserted")

        axios // getting events and shows - note the page parameter in the api link
        .get('https://app.ticketmaster.com/discovery/v2/events.json?apikey=myApiKey&countryCode=DK&size=200&page=0')
        .then(response => {
          const eventsToBeInserted = response.data._embedded.events.map(events => { // preparing events
            const event = events._embedded.attractions[0]
            return {
              sourceID: event.id,
              name: event.name,
              slug: slugify(event.name).toLowerCase(),
              tags: !!event.classifications ? [event.classifications[0].genre.name, event.classifications[0].subGenre.nam] : [], // duplicate genres occur
              // possible tags from ticketmaster: type and subtype
            }
          })

          // Create all events at once
            Event.create(eventsToBeInserted).then(events => {
              console.log("events inserted")

              const showsToBeInserted = response.data._embedded.events.map(show => {
                const event = events.find(event => event.sourceID == show._embedded.attractions[0].id);
                const venue = venues.find(venue => venue.sourceID == show._embedded.venues[0].id);

                if (!!event && !!venue) {
                  return {
                    event: event._id,
                    venue: venue._id,
                    timezone: show.dates.timezone,
                    dateStart: !!show.dates.start.dateTime ? show.dates.start.dateTime : show.dates.start.localDate,
                    tickets: !!show.priceRanges ? {
                      minPrice: show.priceRanges[0].min,
                      maxPrice: show.priceRanges[0].max,
                      currency: show.priceRanges[0].currency
                    }: {} 
                  }
                }
              })
               // Let's see what we have created in the database
                Venue.find({}).select({
                  name: 1,
                  slug: -1
                }).limit(10).populate('event').populate('venue').then(events => {
                  console.log(util.inspect(events));
                }).catch(err => {
                  console.error(err);
                });
             }).catch( err => {
               console.error(err)
             })

            }).catch( err => {
              console.error(err)
            })
        }).catch(err => {
          console.error(err)
      });
    }).catch(err => {
  console.error(err)
  })
})
