如何使用C#TwilioRestClient和nextpageuri进行分页

本文关键字：分页 nextpageuri 何使用 C#TwilioRestClient | 更新日期: 2023-09-27 18:30:11

我目前以以下方式使用TwilioRestClient（这显然是一个循环）：

var currentPage = 0;
private TwilioRestClient mTwilioClient;
var listRequest = new MessageListRequest()
                {
                    To = PhoneNumber,
                    Count = mMessagesPerPage,
                    DateSent = DateTime.Today.Subtract(TimeSpan.FromDays(mDaysToSearch)),
                    DateSentComparison = ComparisonType.GreaterThanOrEqualTo,
                    PageNumber = currentPage++,
                };
var result = mTwilioClient.ListMessages(listRequest);

这对我来说很好，但我正在阅读Paging Through API Resources 中的部分

Page参数已被弃用，可能会在将来的API版本中删除。Page参数比nextpageuri慢，如果在使用Page参数进行分页时创建新资源，则连续的页面可能包含重复的数据。

我想开始使用nextpageuri，以防页面在不久的将来贬值。

我的问题是如何通过TwilioRestHelper（C#）使用nextpageuri？我一直找不到这样的例子，也看不到任何合适的方法调用来实现这一点。

如何使用C#TwilioRestClient和nextpageuri进行分页

所以我最终做的事情如下：

private TwilioRestClient mTwilioClient;
var listRequest = new MessageListRequest()
{
    To = PhoneNumber,
    Count = mMessagesPerPage,
    DateSent = DateTime.Today.Subtract(TimeSpan.FromDays(mDaysToSearch)),
    DateSentComparison = ComparisonType.GreaterThanOrEqualTo,
};
var ret = mTwilioClient.ListMessages(options);
// ret.Messages will now have your first page of messages

// For your next page of results
if (ret.NextPageUri != null)
{
     ret.next_page_uri = ret.NextPageUri.ToString().Substring(11);
}
IRestResponse result = mTwilioClient.Execute(new RestSharp.RestRequest(ret.next_page_uri));
// The classes provided by Twilio do not line up with the fields return in Json for some reason, so we have to massage the data a bit.
result.Content = CleanupJsonContent(result.Content);
// Deserialize the Json content into a class.
var nextRet = JsonConvert.DeserializeObject<TwilioResponse>(result.Content);
// Set the next_page_uri string value. We can't use the Uri class since it doesn't seem to be a valid Uri...
nextRet.next_page_uri = nextRet.NextPageUri.ToString().Substring(11);
private string CleanupJsonContent(string jsonContent)
{
    string ret = jsonContent.Replace("date_sent", "DateSent");
    ret = ret.Replace("account_sid", "AccountSid");
    ret = ret.Replace("date_created", "DateCreated");
    ret = ret.Replace("date_updated", "DateUpdated");
    ret = ret.Replace("num_segments", "NumSegments");
    ret = ret.Replace("api_version", "ApiVersion");
    ret = ret.Replace("price_unit", "PriceUnit");
    ret = ret.Replace("error_code", "ErrorCode");
    ret = ret.Replace("error_message", "ErrorMessage");
    ret = ret.Replace("first_page_uri", "FirstPageUri");
    ret = ret.Replace("previous_page_uri", "PreviousPageUri");
    ret = ret.Replace("page_size", "PageSize");
    ret = ret.Replace("next_page_uri", "NextPageUri");
    ret = ret.Replace("num_pages", "NumPages");
    ret = ret.Replace("last_page_uri", "LastPageUri");
    return ret;
}
