Integrate SharePoint Office 365 into .net core project - sharepoint-online

Question

I would like to share some bit of experience and troubles that I met while doing a folder creation and moving by using RESTful API.

Answer 1

**Create a Folder: **
You will need sharePoint Token
public async Task<JObject> getSharePointToken()
{
var sharPointTokenRequestUrl = "https://accounts.accesscontrol.windows.net/" + _configuration["MicrosoftGraph: TenantId"] + "/tokens/OAuth/2";
var parameters = new Dictionary<string, string>();
parameters["grant_type"] = "client_credentials";
parameters["client_id"] = "your client id";
parameters["client_secret"] = "your client secret";
parameters["resource"] = "resource id";
var par = new FormUrlEncodedContent(parameters);
using (var httpClient = new HttpClient())
{
using (var request = new HttpRequestMessage(new HttpMethod("POST"), sharPointTokenRequestUrl))
{
var response = await httpClient.PostAsync(sharPointTokenRequestUrl, par);
string responseBody = await response.Content.ReadAsStringAsync();
var result = JObject.Parse(responseBody);
return result;
}
}
}
Also You will need XRequest Digest
public async Task<JObject> getXRequestDigest()
{
var sharPointXRequestDigesttUrl = "https://your site /_api/contextinfo";
var sharePointTokenString = getSharePointToken().Result.ToString();
var sharePointToken = JsonConvert.DeserializeObject<SharePointTokenDto>(sharePointTokenString);
var parameters = new Dictionary<string, string>();
var par = new FormUrlEncodedContent(parameters);
using (var httpClient = new HttpClient())
{
httpClient.DefaultRequestHeaders.Add("Authorization", "Bearer " + sharePointToken.access_token);
httpClient.DefaultRequestHeaders.Add("Accept", "application/json;odata=verbose");
using (var request = new HttpRequestMessage(new HttpMethod("POST"), sharPointXRequestDigesttUrl))
{
var response = await httpClient.PostAsync(sharPointXRequestDigesttUrl, par);
string responseBody = await response.Content.ReadAsStringAsync();
var result = JObject.Parse(responseBody);
return result;
}
}
}
Then you could Crate Folder In SharePoint
namespace Sharepoint.Dtos
{
public class SharePointTokenDto
{
public string token_type { get; set; }
public string expires_in { get; set; }
public string not_before { get; set; }
public string expires_on { get; set; }
public string resource { get; set; }
public string access_token { get; set; }
}
}
public async Task<Boolean> CrateFolderInSharePoint(string folderPath)
{
var sharePointTokenString = getSharePointToken().Result.ToString();
var sharePointToken = JsonConvert.DeserializeObject<SharePointTokenDto>(sharePointTokenString);
var xRequestDigest = await getXRequestDigest();
var FormDigestValue = xRequestDigest["d"]["GetContextWebInformation"]["FormDigestValue"];
var siteUrl = "https://yoursites-url/sites/SiteName/_api/web/folders";
var folderUrl = "/sites/SiteName/Shared Documents" + folderPath;
var body = new Dictionary<string, string>
{
{ "ServerRelativeUrl", folderUrl }
};
string bodyString = JsonConvert.SerializeObject(body);
bodyString.Insert(0, " \"__metadata\": { \"type\": \"SP.Folder\" } ");
var content = new StringContent(bodyString, Encoding.UTF8, "application/json");
using (var httpClient = new HttpClient())
{
httpClient.DefaultRequestHeaders.Add("Authorization", "Bearer " + sharePointToken.access_token);
httpClient.DefaultRequestHeaders.Add("Accept", "application/json;odata=verbose");
httpClient.DefaultRequestHeaders.Add("X-RequestDigest", FormDigestValue.ToString());
using (var request = new HttpRequestMessage(new HttpMethod("POST"), siteUrl))
{
var response = await httpClient.PostAsync(siteUrl, content);
string responseBody = await response.Content.ReadAsStringAsync();
var result = JObject.Parse(responseBody);
if (response.IsSuccessStatusCode)
{
return true;
}
else
{
return false;
}
}
}
}
