hi，
I used Google ads api to get the report data, but I encountered a paging
problem
How to understand the two things: limit in SQL and setPageSize in request
The first request page token is empty, limit 2000 returned 2000 When the
second request page token was passed, the next page token returned for the
first time, limit 2000 returned 1000 data, and the next page token returned
empty, so it ended.
Because two requests were sent, the data after deduplication was 2000。
What should I do if I want to get data in pages？？
here is my code:
public String getCampaignReport(String customerId, int size, String
pageToken) {
// Creates a request that will retrieve all campaigns using pages of the
specified page size.
String query = "SELECT customer.id, "
+ "campaign.id, "
+ "campaign.name, "
+ "segments.ad_network_type, segments.date,"
+ "metrics.impressions, "
+ "metrics.clicks, metrics.average_cost, metrics.interactions,"
+ "metrics.cost_per_conversion "
+ "FROM campaign where segments.date BETWEEN '2018-10-10' AND
'2020-04-12'";
if (size > 0) {
query = query + " LIMIT " + size;
}
log.info("pageToken {} , query sql {}", pageToken, query);
SearchGoogleAdsRequest.Builder builder =
SearchGoogleAdsRequest.newBuilder()
.setCustomerId(customerId)
.setPageSize(1000)
.setQuery(query);
if (!Strings.isNullOrEmpty(pageToken)) {
builder.setPageToken(pageToken);
}
// Issues the search request.
SearchPagedResponse searchPagedResponse =
googleAdsServiceClient.search(builder.build());
if (searchPagedResponse == null) {
log.info("searchPagedResponse null");
return "";
}
List<Long> sizeList = Lists.newLinkedList();
Set<Long> sizeSet = Sets.newHashSet();
// Iterates over all rows in all pages and prints the requested field
values for the campaign
// in each row.
for (GoogleAdsRow googleAdsRow : searchPagedResponse.iterateAll()) {
Campaign campaign = googleAdsRow.getCampaign();
Segments segments = googleAdsRow.getSegments();
Metrics metrics = googleAdsRow.getMetrics();
log.info("Campaign with ID {} and name {} was found. "
+ "segments date {}, network_type {}"
+ "Campaign {}, {}, {}, {}, {}, {}",
campaign.getId().getValue(), campaign.getName().getValue(),
segments.getDate().getValue(), segments.getAdNetworkType(),
metrics.getImpressions().getValue(), metrics.getClicks().getValue(),
metrics.getCostPerConversion().getValue(),
metrics.getAverageCost().getValue(),
metrics.getInteractions().getValue(),
metrics.getAverageCost().getValue() *
metrics.getInteractions().getValue());
sizeList.add(campaign.getId().getValue());
sizeSet.add(campaign.getId().getValue());
}
log.info("list size {}, set size {}, next page token {}", sizeList.size(),
sizeSet.size(), searchPagedResponse.getNextPageToken());
return searchPagedResponse.getNextPageToken();
}
public void getAllCampaignReport(String customerId, int size) {
String nextPageToken = getCampaignReport(customerId, size, null);
while (!Strings.isNullOrEmpty(nextPageToken)) {
nextPageToken = getCampaignReport(customerId, size, nextPageToken);
}
}
