Question

SciTS Mendeley集团目前有1205项资源（引用）。但是，无论我们如何调用API的“getDocuments”方法，我们只获得前1000个资源。我们需要传递一个特定参数来获取完整的资源列表吗？或者有没有办法进行后续调用，使第一次调用不返回数据页？

    string grantType = "client_credentials";
    string applicationID = "id";
    string clientsecret = "XXXXXXX";
    string redirecturi = "*******";
    string url = "https://api-oauth2.mendeley.com/oauth/token";
    string view = "all";
    string group_id = "f7c0e437-f68b-34df-83c7-2877147ba8f9";
    HttpWebResponse response = null;

    try
    {
        // Create the data to send
        StringBuilder data = new StringBuilder();
        data.Append("client_id=" + Uri.EscapeDataString(applicationID));
        data.Append("&client_secret=" + Uri.EscapeDataString(clientsecret));
        data.Append("&redirect_uri=" + Uri.EscapeDataString(redirecturi));
        data.Append("&grant_type=" + Uri.EscapeDataString(grantType));

        data.Append("&response_type=" + Uri.EscapeDataString("code"));
        data.Append("&scope=" + Uri.EscapeDataString("all"));

        byte[] byteArray = Encoding.UTF8.GetBytes(data.ToString());

        // Setup the Request
        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
        request.Method = "POST";
        request.ContentType = "application/x-www-form-urlencoded";
        request.ContentLength = byteArray.Length;

        // Write data
        Stream postStream = request.GetRequestStream();
        postStream.Write(byteArray, 0, byteArray.Length);
        postStream.Close();

        // Send Request & Get Response
        response = (HttpWebResponse)request.GetResponse();
        string accessToken;
        using (StreamReader reader = new StreamReader(response.GetResponseStream()))
        {
            // Get the Response Stream
            string json = reader.ReadLine();
            Console.WriteLine(json);

            // Retrieve and Return the Access Token
            JavaScriptSerializer ser = new JavaScriptSerializer();
            Dictionary<string, object> x = (Dictionary<string, object>)ser.DeserializeObject(json);
            accessToken = x["access_token"].ToString();
        }
        // Console.WriteLine("Access TOken"+ accessToken);

        var apiUrl = "https://api-oauth2.mendeley.com/oapi/documents/groups/3556001/docs/?details=true&items=1250";

        try

            request = (HttpWebRequest)WebRequest.Create(apiUrl);
            request.Method = "GET";
            request.Headers.Add("Authorization", "Bearer " + accessToken);

            request.Host = "api-oauth2.mendeley.com";

            response = (HttpWebResponse)request.GetResponse();
            using (StreamReader reader = new StreamReader(response.GetResponseStream()))
            {
                // Get the Response Stream

                Console.WriteLine(json);
                //need this to import documents

            }
                          }
        catch (WebException ex1)
        {

            Console.WriteLine("Access TOken exception" + ex1.Message);
        }


    }
    catch (WebException e)
    {

        if (e.Response != null)
        {
            using (HttpWebResponse err = (HttpWebResponse)e.Response)
            {
                Console.WriteLine("The server returned '{0}' with the status code '{1} ({2:d})'.",
                  err.StatusDescription, err.StatusCode, err.StatusCode);
            }
        }
    }

返回的默认项目数限制为每页1000个。对于分页响应，您应该在响应中获得一些额外的字段;值得注意的是＆＃39; items_per_page＆＃39;，＆＃39; total_pages＆＃39;，＆＃39; total_results＆＃39;。

我怀疑你有两页要获得下一个结果，你需要追加＆＃39; page = 1＆＃39;。
