適用post put 請求

最背景：近單位用elasticsearch升級從2.4X升級到5.X，增加了auth的許可權驗證。使用的PlainElastic.Net元件，該元件原始碼支援許可權有問題，下載了原始碼更改了下。

本質是把使用者名稱和密碼放到了head裡。

authString =“使用者名稱:密碼@127.0.0.1”；

 string authUrl = url.Replace("http://","");
            string authString = authUrl.Substring(0, authUrl.LastIndexOf("@"));

            if
 
 (!string.IsNullOrWhiteSpace(authString))
            {
                var array = authString.Split(':');               
                string  userName = array[0];
                string password = array[1];
                string encoded = Convert.ToBase64String(Encoding.GetEncoding("ISO-8859-1").GetBytes($"{userName}:{password}"
 
));
                request.Headers.Add("Authorization", $"Basic {encoded}");
            }

或者

WebRequest request = WebRequest.Create(url);
request.Credentials = GetCredential();
request.PreAuthenticate = true;

private CredentialCache GetCredential(string url)
{

    string authUrl = url.Replace
 
("http://","");
    string authString = authUrl.Substring(0, authUrl.LastIndexOf("@"));

    string  userName = array[0];
    string  password = array[1];

    ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3;
    CredentialCache credentialCache = new CredentialCache();
    credentialCache.Add(new System.Uri(url), "Basic", new NetworkCredential(userName, password ));
    return credentialCache;
}
