SharePoint -- Update the Contents of a File (PUT)

Demonstrates how to update the contents of a SharePoint file. Go

    success := false

    // This requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    http := chilkat.NewHttp()

    // If SharePoint Windows classic authentication is used, then set the 
    // Login, Password, LoginDomain, and NtlmAuth properties.
    http.SetLogin("SHAREPOINT_USERNAME")
    http.SetPassword("SHAREPOINT_PASSWORD")
    http.SetLoginDomain("SHAREPOINT_NTLM_DOMAIN")
    http.SetNtlmAuth(true)

    // The more common case is to use SharePoint Online authentication (via the SPOIDCRL cookie).
    // If so, do not set Login, Password, LoginDomain, and NtlmAuth, and instead
    // establish the cookie as shown at SharePoint Online Authentication

    // Indicate that we want a JSON reply
    http.SetAccept("application/json;odata=verbose")

    // Update /Documents/ChilkatTest/sample.docx with new content...
    req := chilkat.NewHttpRequest()
    req.SetHttpVerb("POST")
    req.SetPath("/_api/web/GetFileByServerRelativeUrl('/Documents/ChilkatTest/sample.docx')/$value")
    // Give the location of the file to be uploaded.  
    // Note: The file is not loaded into memory at this point.  It is never fully loaded
    // into memory.  Instead, the file data is streamed directly from the file when
    // when the upload occurs.
    req.StreamBodyFromFile("qa_data/msword/sample.docx")

    // We need to add a form digest value in the X-RequestDigest header field.
    // See this example for details on
    // how to get (and cache) a form digest value
    req.AddHeader("X-RequestDigest","SHAREPOINT_FORM_DIGEST")

    // Also need to add this header..
    req.AddHeader("X-HTTP-Method","PUT")

    // Upload..

    // A non-successful update will return a JSON response body..
