asp.net - 门德利分页

Question

1. SciTS Mendeley 小组目前有 1205 个资源（引用）。但是，无论我们如何调用 API 的“getDocuments”方法，我们都只能获取前 1000 个资源。我们需要传递一个特定的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以获取第一次调用未返回的数据页？

       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
                   string json = reader.ReadLine();
                   Console.WriteLine(json);
                   //need this to import documents
   
               }
                             }
           catch (WebException ex1)
           {
   
               Console.WriteLine("Access TOken exception" + ex1.Message);

       {
   
           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；尤其是“items_per_page”、“total_pages”、“total_results”。

我怀疑你有两页，要获得下一个结果，你需要附加'page = 1'。
