部署.Net7 Blazor WASM至Azure App Service遇防伪造SSL配置错误

我正尝试将一个.NET 7 Blazor WASM应用部署到带有自定义域名的Azure App Service中，部署后出现如下错误：

System.InvalidOperationException: The antiforgery system has the configuration value AntiforgeryOptions.Cookie.SecurePolicy = Always, but the current request is not an SSL request.

我的App Service已配置为仅使用HTTPS，且已安装托管SSL证书。

我的相关配置 #

Startup.cs 中的防伪造功能配置 #

services.AddAntiforgery(options =>
{
    options.HeaderName = "X-XSRF-TOKEN";
    options.Cookie.Name = "__someCookieName";
    options.Cookie.SameSite = SameSiteMode.Strict;
    options.Cookie.SecurePolicy = CookieSecurePolicy.Always;
});

_Host.cshtml 配置 #

我的Blazor应用由服务器提供索引页面，而非使用index.razor：

<script src="antiForgeryToken.js" ></script>
    @Html.AntiForgeryToken()

.csproj 配置 #
