Sharepoint API将新项目发布到列表 [英] Sharepoint API Post a new Item to a List

问题描述

Hellow

我想用post / rest（C＃）命令向List中添加一个新项目SharePoint中。我可以从API获取数据 - >这是有效的。

pw被删除

          SecureString passWord = new SecureString（）;

            foreach（char c in"" .ToCharArray（））

            {

                passWord.AppendChar（c）;

            }


            HttpWebRequest endpointRequest =  （HttpWebRequest）HttpWebRequest.Create（""）;

            endpointRequest.Method =" GET";

            endpointRequest.Accept =" application / json; odata = verbose";

            endpointRequest.Credentials = new SharePointOnlineCredentials（""，passWord）;

            endpointRequest.Headers.Add（"授权"，"承载"+"""）;

            HttpWebResponse endpointResponse =  （HttpWebResponse）endpointRequest.GetResponse（）;
$


           试试
            {

                WebResponse webResponse = endpointRequest.GetResponse（）;

               流webStream = webResponse.GetResponseStream（）;

                StreamReader responseReader = new StreamReader（webStream）;

                string response = responseReader.ReadToEnd（）;

                

                



                responseReader.Close（）;

                Console.ReadLine（）;

            }¥b $ b            catch（例外X）

            {

$
            }

现在我想要将项目上传到列表中，并且响应是禁止的403 

            string json = string.Empty;



            SecureString passWord = new SecureString（）;

            foreach（char c in"" .ToCharArray（））

            {

                passWord.AppendChar（c）;

            }


            json =" {\" KlantNr \"：\" 2563 \"，\" Klant \"：\" testmattijs \"}" ;;

            ASCIIEncoding encoder = new ASCIIEncoding（）;

            byte [] data = encoder.GetBytes（json）;



            HttpWebRequest endpointRequest =（HttpWebRequest）HttpWebRequest.Create（""）;

            endpointRequest.Method =" POST";

            endpointRequest.Accept =" application / json; odata = verbose";

            endpointRequest.ContentType =" application / json; odata = verbose";

            endpointRequest.ContentLength = data.Length;

            endpointRequest.Credentials = new SharePointOnlineCredentials（""，passWord）;

            endpointRequest.Headers.Add（"授权"，"承载"+"""）;

            



           试试
            {

               使用（Stream newStream = endpointRequest.GetRequestStream（））

                {

                    newStream.Write（data，0，data.Length）;

                    newStream.Flush（）;

                    newStream.Close（）;
$


                    HttpWebResponse response = endpointRequest.GetResponse（）as HttpWebResponse;

                }¥b $ b            }¥b $ b            catch（例外X）

            {

                string s = X.Message.ToString（）;

            } 

解决方案

我建议您使用SharePoint CSOM，这样您就可以轻松实现这一目标。

您可以通过工具在Visual Studio中安装SDK-> NuGet包管理器 - >

包管理器控制台

https://www.nuget.org/packages/Microsoft.SharePointOnline.CSOM

CSOM对CRUD的示例代码。

 ListItemCreationInformationlistCreationInformation = newListItemCreationInformation（）; 
 ListItemoListItem = oList.AddItem（listCreationInformation） ）; 
 oListItem [" Title"] =" Hello World"; 
 oListItem.Update（）; 
 clientContext.ExecuteQuery（）;

I want with post/rest (C#) command add a new item to a List in Sharepoint. I Can get data from the API -> this works.

pw are deleted

          SecureString passWord = new SecureString();
            foreach (char c in "".ToCharArray())
            {
                passWord.AppendChar(c);
            }

            HttpWebRequest endpointRequest =  (HttpWebRequest)HttpWebRequest.Create("");
            endpointRequest.Method = "GET";
            endpointRequest.Accept = "application/json;odata=verbose";
            endpointRequest.Credentials = new SharePointOnlineCredentials("", passWord);
            endpointRequest.Headers.Add("Authorization", "Bearer " + "");
            HttpWebResponse endpointResponse =  (HttpWebResponse)endpointRequest.GetResponse();

            try
            {
                WebResponse webResponse = endpointRequest.GetResponse();
                Stream webStream = webResponse.GetResponseStream();
                StreamReader responseReader = new StreamReader(webStream);
                string response = responseReader.ReadToEnd();
                
                

                responseReader.Close();
                Console.ReadLine();
            }
            catch (Exception X)
            {

            }

now I want a upload a item to a list and the respons is Forbidden 403 

            string json = string.Empty;

            SecureString passWord = new SecureString();
            foreach (char c in "".ToCharArray())
            {
                passWord.AppendChar(c);
            }

            json = "{\"KlantNr\":\"2563\",\"Klant\":\"testmattijs\"}";
            ASCIIEncoding encoder = new ASCIIEncoding();
            byte[] data = encoder.GetBytes(json);

            HttpWebRequest endpointRequest = (HttpWebRequest)HttpWebRequest.Create("");
            endpointRequest.Method = "POST";
            endpointRequest.Accept = "application/json;odata=verbose";
            endpointRequest.ContentType = "application/json;odata=verbose";
            endpointRequest.ContentLength = data.Length;
            endpointRequest.Credentials = new SharePointOnlineCredentials("", passWord);
            endpointRequest.Headers.Add("Authorization", "Bearer " + "");
            

            try
            {
                using (Stream newStream = endpointRequest.GetRequestStream())
                {
                    newStream.Write(data, 0, data.Length);
                    newStream.Flush();
                    newStream.Close();

                    HttpWebResponse response = endpointRequest.GetResponse() as HttpWebResponse;
                }
            }
            catch (Exception X)
            {
                string s = X.Message.ToString();
            }

Hi,

I suggest you use SharePoint CSOM so you could achieve this easily.

You could install SDK in Visual Studio by Tools->NuGet Package Manager-> Package Manager Console

https://www.nuget.org/packages/Microsoft.SharePointOnline.CSOM

Sample code to CRUD by CSOM.

ListItemCreationInformationlistCreationInformation = newListItemCreationInformation();
ListItemoListItem = oList.AddItem(listCreationInformation);
oListItem["Title"] = "Hello World";
oListItem.Update();
clientContext.ExecuteQuery();
