對於大多數情況，OAuth 2.0和OpenID Connect授權端點的GET請求需要具有許多查詢字符串參數。

雖然您可以使用任何方法創建帶參數的URL來創建正確的字符串，但RequestUrl類是完成此任務的簡單幫助程序。

特別是，您可以使用CreateAuthorizeUrl擴展方法為授權端點創建URL - 它支持最常用的參數：

/// <summary>
/// Creates an authorize URL.
/// </summary>
/// <param name="request">The request.</param>
/// <param name="clientId">The client identifier.</param>
/// <param name="responseType">The response type.</param>
/// <param name="scope">The scope.</param>
/// <param name="redirectUri">The redirect URI.</param>
/// <param name="state">The state.</param>
/// <param name="nonce">The nonce.</param>
/// <param name="loginHint">The login hint.</param>
/// <param name="acrValues">The acr values.</param>
/// <param name="prompt">The prompt.</param>
/// <param name="responseMode">The response mode.</param>
/// <param name="codeChallenge">The code challenge.</param>
/// <param name="codeChallengeMethod">The code challenge method.</param>
/// <param name="display">The display option.</param>
/// <param name="maxAge">The max age.</param>
/// <param name="uiLocales">The ui locales.</param>
/// <param name="idTokenHint">The id_token hint.</param>
/// <param name="extra">Extra parameters.</param>
/// <returns></returns>
public static string CreateAuthorizeUrl(this RequestUrl request,
    string clientId,
    string responseType,
    string scope = null,
    string redirectUri = null,
    string state = null,
    string nonce = null,
    string loginHint = null,
    string acrValues = null,
    string prompt = null,
    string responseMode = null,
    string codeChallenge = null,
    string codeChallengeMethod = null,
    string display = null,
    int? maxAge = null,
    string uiLocales = null,
    string idTokenHint = null,
    object extra = null)
{ ... }
 

例：

var ru = new RequestUrl("https://demo.identityserver.io/connect/authorize");

var url = ru.CreateAuthorizeUrl(
    clientId: "client",
    responseType: "implicit",
    redirectUri: "https://app.com/callback",
    nonce: "xyz",
    scope: "openid");
 

註意
該extra參數可以是一個串字典或任意其它具有屬性的類型。在這兩種情況下，值都將序列化為鍵/值。
