Webhttprequest for use in SharePoint document libraries

Write in front

Because the site on the SharePoint server is logged on as a domain user Windows authentication, and the app project can provide a username and password, the customer is reluctant to transfer this on the network. So it provides a way to use SSL certificate authentication. The combination of Webhttprequest and SharePoint's client object model is pretty reliable, and here are two ways to upload a file with a certificate sending request.

Core code

IsNullOrEmpty ( This. _siteinfo.username)) -             { the                 return string. Empty.toerrorjson (" -",NewArgumentNullException ("User Name parameter is empty"). Message); -             } -ClientContext SpContext =NewClientContext ( This. _siteinfo.appurl); -             //spcontext.credentials = new NetworkCredential (This._username, This._pwd, this.strdomain); +             /* - * SSL Support + * SSL authentication protocol relies on certificates : A The support for SSL in the * NET Framework consists of two parts.  at * SSL on HTTP is a special case (but most widely used) implemented by the HttpWebRequest class, which is ultimately available to the WEB service client proxy.  - * To enable SSL, you do not have to perform any special operations except to specify a URL that uses the Https: protocol.  - * When connecting to an SSL-protected endpoint, the server certificate is validated on the client.  - * If validation fails, the connection is immediately closed based on the default settings.

In this way, certificates can be used directly for authentication without providing account information. Here are some ideas and hope to help you.

Summarize

Uploading files in SharePoint, using the client object model is a simpler way of comparing the rest API, using the rest API, I did not succeed, do not know that the place is a problem, it is a headache, finally no way to adopt this way.
