Blazor WebAssembly Hosted API URL

Question

正在尝试理解默认的Blazor WebAssembly ASP.NET托管模板。。。我的问题是服务器应用程序托管的API到底在什么位置？

客户端应用程序简单地调用API"API"；天气预报"：

await Http.GetFromJsonAsync<WeatherForecast[]>("WeatherForecast");

但是，如果您手动导航到http://localhost:xxxxx/weatherforecast

如果我想查看原始JSON结果，那么实际的API端点是什么？

Answer 1

在blazor组件中，注入了一个HttpClient。

@* Injection of HttpClient *@
@inject HttpClient Http
@* your page/component code *@
@foreach (var f in forecasts)
{
<div>
@f.SomeProperty
</div>
}
@code {
private WeatherForecast[] forecasts;
protected override Task OnInitilizeAsync()
{
// Use HttpClient injected at top
forecasts = Http.GetFromJsonAsync<WeatherForecast[]>("weatherforecast");
}
}

在Program类中，有一个Main(string[])方法，用于注册所有服务：

// create a Builder for Blazor WebAssembly
var builder = WebAssemblyHostBuilder.CreateDefault(args);
// Register a HttpClient in services
// builder.HostEnvironment.BaseAddress = domain of your app (localhost, www.example.com, ...)
builder.Services.AddScoped(sp => new HttpClient { BaseAddress = new Uri(builder.HostEnvironment.BaseAddress) });
