一种解决方法是使用 Blazor WebAssembly 的代理,该代理可将资源路径转换为静态文件的相对路径。具体实现可以参考以下示例代码:
// Startup.cs public void ConfigureServices(IServiceCollection services) { services.AddControllersWithViews().AddNewtonsoftJson();
services.AddHttpClient("BlazorServerAPI", client =>
{
client.BaseAddress = new Uri(Configuration["BlazorServerAPI"]);
});
services.AddSingleton();
}
public void Configure(IApplicationBuilder app, IWebHostEnvironment env) { app.UseStaticFiles();
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
else
{
app.UseExceptionHandler("/Error");
app.UseHsts();
}
app.UseHttpsRedirection();
app.UseRouting();
app.UseEndpoints(endpoints =>
{
endpoints.MapControllers();
endpoints.MapFallbackToFile("index.html");
});
app.UseBlazorFrameworkFiles();
app.Use(async (context, next) =>
{
if (context.Request.Path.Value.StartsWith("/_blazor"))
{
var proxy = context.RequestServices.GetRequiredService();
await proxy.HandleRequestAsync(context);
}
await next();
});
}
public class BlazorResourceProxy { private readonly HttpClient _httpClient;
public BlazorResourceProxy(IHttpClientFactory httpClientFactory)
{
_httpClient = httpClientFactory.CreateClient("BlazorServerAPI");
}
public async Task HandleRequestAsync(HttpContext context)
{
var path = context.Request.Path.Value.Substring("/_blazor".Length);
var response = await _httpClient.GetAsync(path);
if (!response.IsSuccessStatusCode)
{
context.Response.StatusCode = (int)response.StatusCode;
return;
}
var contentType = response.Content.Headers.ContentType.ToString();
context.Response.ContentType = contentType;
var stream = await response.Content.ReadAsStreamAsync();
await stream.CopyToAsync(context.Response.Body);
}
}
在类似于这样的示例中,BlazorResourceProxy 类处理静态资源的请求。然后,Use 方法将代理添加到管道中。
注意:在以上示例中,“BlazorServerAPI”应该替换为您 Blazor WebAssembly 应用程序的 API 地址。
