Bill Filtering only returns default 10 sorted reco

问题:

Please find the below code for for filtering bills, which returns only 10 sorted records even I passed the resultperpage>10.

public IEnumerable<Intuit.Ipp.Data.Qbo.Bill> FilterBills(DataServices dataServices, int startPage, int resultsPerPage, DateTime After, DateTime Before)
    {
Intuit.Ipp.Security.OAuthRequestValidator oAuthRequestValidator = ((Intuit.Ipp.Security.OAuthRequestValidator)dataServices.ServiceContext.RequestValidator);

            OAuthConsumerContext consumerContext = new OAuthConsumerContext
            {
                ConsumerKey = oAuthRequestValidator.ConsumerKey,
                SignatureMethod = SignatureMethod.HmacSha1,
                ConsumerSecret = oAuthRequestValidator.ConsumerSecret
            };

            OAuthSession oSession = new OAuthSession(consumerContext, "https://oauth.intuit.com/oauth/v1/get_request_token",
                        "https://workplace.intuit.com/Connect/Begin",
                        "https://oauth.intuit.com/oauth/v1/get_access_token");

            oSession.AccessToken = new TokenBase
            {
                Token = oAuthRequestValidator.AccessToken,
                ConsumerKey = oAuthRequestValidator.ConsumerKey,
                TokenSecret = oAuthRequestValidator.AccessTokenSecret
            };

            var body = "PageNum={0}&ResultsPerPage={1}&Filter=LastUpdatedTime :AFTER: {2} :AND: LastUpdatedTime :BEFORE: {3} & Sort=LastUpdatedTime HighToLow";
            body = String.Format(body, startPage, resultsPerPage, After.ToString("yyyy-mm-ddTHH:MM:ssz"), Before.ToString("yyyy-mm-ddTHH:MM:ssz"));

            IConsumerRequest conReq = oSession.Request();
            conReq = conReq.Post().WithRawContentType("application/x-www-form-urlencoded").WithRawContent(System.Text.Encoding.ASCII.GetBytes(body)); ;
            conReq = conReq.ForUrl(dataServices.ServiceContext.BaseUrl + "bills/v2/" + dataServices.ServiceContext.RealmId);
            conReq = conReq.SignWithToken();

            Intuit.Ipp.Data.Qbo.SearchResults searchResults = (Intuit.Ipp.Data.Qbo.SearchResults)dataServices.ServiceContext.Serializer.Deserialize<Intuit.Ipp.Data.Qbo.SearchResults>(conReq.ReadBody());
            IEnumerable<Intuit.Ipp.Data.Qbo.Bill> SearchResult = ((Intuit.Ipp.Data.Qbo.Bills)(searchResults.CdmCollections)).Bill;
            return SearchResult;
 }

After sending the request i m getting the respose as 10 sorted bill record without getting any error. I am using IPPDotNetDevKit 2.1.12.0 version.

Please Look into this filtering problem.

The OAuth parameters are being passed in the body of the request in your example above and overwriting your request body, so it is defaulting to PageNum=1&ResultsPerPage=20. Also, the date is formatted incorrectly. Here is a code sample that will work.

public IEnumerable<Intuit.Ipp.Data.Qbo.Bill> FilterBills(DataServices dataServices, int startPage, int resultsPerPage, DateTime After, DateTime Before)
{
    StringBuilder requestXML = new StringBuilder();
    StringBuilder responseXML = new StringBuilder();

    var requestBody =
        "PageNum={0}&ResultsPerPage={1}&Filter=LastUpdatedTime :AFTER: {2} :AND: LastUpdatedTime :BEFORE: {3}&Sort=LastUpdatedTime HighToLow";
    requestBody = String.Format(requestBody, startPage, resultsPerPage, After.ToString("yyyy-MM-ddThh:mm:sszzz"),
                            Before.ToString("yyyy-MM-ddThh:mm:sszzz"));

    HttpWebRequest httpWebRequest =
        WebRequest.Create(dataServices.ServiceContext.BaseUrl + "bills/v2/" +
                            dataServices.ServiceContext.RealmId) as HttpWebRequest;
    httpWebRequest.Method = "POST";
    httpWebRequest.ContentType = "application/x-www-form-urlencoded";
    httpWebRequest.Headers.Add("Authorization", GetDevDefinedOAuthHeader(httpWebRequest, requestBody));
    requestXML.Append(requestBody);
    UTF8Encoding encoding = new UTF8Encoding();
    byte[] content = encoding.GetBytes(requestXML.ToString());
    using (var stream = httpWebRequest.GetRequestStream())
    {
        stream.Write(content, 0, content.Length);
    }
    HttpWebResponse httpWebResponse = httpWebRequest.GetResponse() as HttpWebResponse;
    using (Stream data = httpWebResponse.GetResponseStream())
    {
        Intuit.Ipp.Data.Qbo.SearchResults searchResults =
            (Intuit.Ipp.Data.Qbo.SearchResults)
            dataServices.ServiceContext.Serializer.Deserialize<Intuit.Ipp.Data.Qbo.SearchResults>(
                new StreamReader(data).ReadToEnd());
        return ((Intuit.Ipp.Data.Qbo.Bills) searchResults.CdmCollections).Bill.ToList();
    }
}


private string GetDevDefinedOAuthHeader(HttpWebRequest webRequest, string requestBody)
{

    OAuthConsumerContext consumerContext = new OAuthConsumerContext
    {
        ConsumerKey = consumerKey,
        ConsumerSecret = consumerSecret,
        SignatureMethod = SignatureMethod.HmacSha1,
        UseHeaderForOAuthParameters = true

    };

    consumerContext.UseHeaderForOAuthParameters = true;

    OAuthSession oSession = new OAuthSession(consumerContext, "https://www.example.com",
                            "https://www.example.com",
                            "https://www.example.com");


    oSession.AccessToken = new TokenBase
    {
        Token = accessToken,
        ConsumerKey = consumerKey,
        TokenSecret = accessTokenSecret
    };

    IConsumerRequest consumerRequest = oSession.Request();
    consumerRequest = ConsumerRequestExtensions.ForMethod(consumerRequest, webRequest.Method);
    consumerRequest = ConsumerRequestExtensions.ForUri(consumerRequest, webRequest.RequestUri);
    if (webRequest.Headers.Count > 0)
    {
        ConsumerRequestExtensions.AlterContext(consumerRequest, context => context.Headers = webRequest.Headers);
        if (webRequest.Headers[HttpRequestHeader.ContentType] == "application/x-www-form-urlencoded")
        {
            Dictionary<string, string> formParameters = new Dictionary<string, string>();
            foreach (string formParameter in requestBody.Split('&'))
            {
                formParameters.Add(formParameter.Split('=')[0], formParameter.Split('=')[1]);
            }
            consumerRequest = consumerRequest.WithFormParameters(formParameters);
        }
    }

    consumerRequest = consumerRequest.SignWithToken();
    return consumerRequest.Context.GenerateOAuthParametersForHeader();
}
