如何解决Amazon Systems Manager 和 Blazor Web Assembly
我正在尝试构建 Blazor wasm 应用程序,并想从 Amazon Systems Manager 参数存储中检索我的敏感应用程序设置。我目前正在为 .Net core web api 后端使用相同的参数存储,但是当我尝试将它添加到我的 Blazor 应用程序时,我在网页开发人员控制台中收到以下异常...

我在 Program.cs 中使用的代码如下:
var builder = WebAssemblyHostBuilder.CreateDefault(args);
builder.RootComponents.Add<App>("#app");
builder.Configuration.AddSystemsManager($"/my_app/{builder.HostEnvironment.Environment}/");
我还应该提到,我已经安装了 AWS CLI 并使用我的开发人员凭证进行了配置,并且我还安装了适用于 Visual Studio 2019 的 AWS 工具包。
