ListIncidents pagination

[atmosx]

Hello! I need to fetch alerts since the beginning of the year. I can't handle pagination. Keeping the default limit of 25 results per page, here's a code sample:

package main

import (
	"github.com/PagerDuty/go-pagerduty"
	"os"
	"strings"
	"fmt"
)

var authtoken = os.Getenv("TOKEN")

func main() {
	var opts pagerduty.ListIncidentsOptions
	opts.Since = "2020-01-01T00:00:00.00-0000"
	client := pagerduty.NewClient(authtoken)
	alerts, err := client.ListIncidents(opts)
	if err != nil {
		panic(err)
	}
	fmt.Printf("More %v\n", alerts.More)
	fmt.Printf("Limit %v\n", alerts.Limit)
	for _, i := range alerts.Incidents {
		desc := strings.Fields(i.Description)[1]
		fmt.Println(desc)
		// fmt.Println(i.Status)
	}
	fmt.Printf("Total %v\n", alerts.Total) // it's always 0!
	fmt.Printf("Offset %v\n", alerts.Offset) // it's always 0!
}

According to the documentation there should a pagination_token method, but there is no such method. However, the available methods are: APIListObject, Incidents, Limit, More, Offset, Total. The Moremethods shows that there's _more_ pages to fetch, however theOffset. method and the Total` method return both zero.

Any hints on how to handle pagination in this case?

According to the docs:

The more field will always be true or false, indicating whether there are more resources matching the query than present in the response (because of the request's limit). If true, you may want to make subsequent requests with a different offset until more is false in order to retrieve all of the resources.

I can use opts.More.

PoC for anyone looking for examples:

package main

import (
	"github.com/PagerDuty/go-pagerduty"
	"os"
	"strings"
	"fmt"
)

var authtoken = os.Getenv("TOKEN")

func main() {
	var opts pagerduty.ListIncidentsOptions
	opts.Since = "2020-01-01T00:00:00.00-0000"
	opts.Offset = uint(1)
	opts.Limit = 100
	client := pagerduty.NewClient(authtoken)
	for {
		alerts, err := client.ListIncidents(opts)
		if err != nil {
			panic(err)
		}
		for _, i := range alerts.Incidents {
			desc := strings.Fields(i.Description)[1]
			fmt.Println(desc)
		}
		if !alerts.More {
			break
		}
		opts.Offset += 1
	}
}
