Goodnight,
I have a site in Sharepoint 2019 with a webpart spfx and I have a site where a web api runs with the business logic. The api has Windows authentication
From SharePoint I can connect to the web api using the following in the http request:
JavaScript code:
this.context.spHttpClient.get('http://custom-api:1011/controller', {}, {
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json'
},
credentials: 'include'
})
I tried with spHttpClient and httpClient
From the web api, I need to connect to sharepoint with the credentials of the current user and perform some actions, but it always generates error 401
C# code:
var handler = new HttpClientHandler {UseDefaultCredentials = true};
HttpClient = new HttpClient (handler);
HttpResponseMessage response = await client.GetAsync ($"{SiteUrl}/_api/web/SiteGroups");
In summary I need to make the following jumps.
SharePoint SPFX => External Web Api => SharePoint api REST.
with spHttpClient the error was {"odata.error":{"code":"-2147024891, System.UnauthorizedAccessException","message":{"lang":"en-US","value":"Access denied. You do not have permission to perform this action or access this resource."}}}
The test user is an administrator of the site collection
Thank you
