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

// -------------------------------------------------------------------------
// The following comments apply to SharePoint Windows classic authentication.
// -------------------------------------------------------------------------
// For example, imagine our SharePoint endpoint is https://xyzoffice.mycompany.com/
// The SHAREPOINT_NTLM_DOMAIN would be "mycompany.com"
// The SHAREPOINT_HTTPS_DOMAIN would be "xyzoffice.mycompany.com"
// Also, the SHAREPOINT_USERNAME would be just the name, not a full email address.
// for example, "chilkat" instead of "chilkat@mycompany.com"

Chilkat.Http http = new Chilkat.Http();

// If SharePoint Windows classic authentication is used, then set the 
// Login, Password, LoginDomain, and NtlmAuth properties.
http.Login = "SHAREPOINT_USERNAME";
http.Password = "SHAREPOINT_PASSWORD";
http.LoginDomain = "SHAREPOINT_NTLM_DOMAIN";
http.NtlmAuth = 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
// -------------------------------------------------------------------------

// This example downloads a CSV file that is utf-8 and contains Japanese characters.

string url = "https://SHAREPOINT_HTTPS_DOMAIN/_api/web/GetFileByServerRelativeUrl('/Documents/ChilkatTest/japanese.csv')/$value";

http.AcceptCharset = "utf-8";

string strCsv = http.QuickGetStr(url);
if (http.LastMethodSuccess != true) {
    Debug.WriteLine(http.LastErrorText);
    return;
}

// The CSV file is contained in strCsv.
Debug.WriteLine("CSV:");
Debug.WriteLine(strCsv);

// Note: The HTTP response hopefully indicates the charset of the response,
// and Chilkat should receive the string correctly.  If the response sent by
// SharePoint does not indicate a charset, or indicates an incorrect charset,
// then we can instead download the text file as binary data and interpret the
// bytes ourselves correctly.  For example:  

Chilkat.BinData bd = new Chilkat.BinData();
bool success = http.QuickGetBd(url,bd);
if (success != true) {
    Debug.WriteLine(http.LastErrorText);
    return;
}

// Interpret the bytes correctly as utf-8
Chilkat.StringBuilder sb = new Chilkat.StringBuilder();
sb.AppendBd(bd,"utf-8",0,0);
Debug.WriteLine("CSV:");
Debug.WriteLine(sb.GetAsString());
