可以在浏览器中预览XLSX或XLS吗？

Question

我有一个MVC ActionResult控制器，可以下载文件。

如果是PDF，则使用此JS代码

//my server client registration code

var webClient = new IdentityServer4.EntityFramework.Entities.Client
{
    ClientId = "mvc",
    ClientName = "MVC Client",
    Description = "Test MVC Client",
    RequireConsent = false,
    AlwaysIncludeUserClaimsInIdToken = true,
    AllowedScopes = new List<ClientScope>
    {
        new ClientScope
        {                       
            Scope = IdentityServerConstants.StandardScopes.OpenId 
        },
        new ClientScope
        {
            Scope = IdentityServerConstants.StandardScopes.Profile
        }
    }
};

//set the grant type
webClient.AllowedGrantTypes = new List<ClientGrantType>
{
    new ClientGrantType
    {
        GrantType = GrantType.Implicit,
        Client = webClient
    }
};

// where to redirect to after login
webClient.RedirectUris = new List<ClientRedirectUri>
{
    new ClientRedirectUri
    {
        RedirectUri = "http://localhost:5000/signin-oidc",
        Client = webClient
    }
};

// where to redirect to after logout
webClient.PostLogoutRedirectUris = new List<ClientPostLogoutRedirectUri>               
{
    new ClientPostLogoutRedirectUri
    {
      PostLogoutRedirectUri="http://localhost:5000/signout-callback-oidc",                       
      Client = webClient
    }
};


//Client configuration
services.AddAuthentication(options => 
{
    options.DefaultScheme = "Cookies";
    options.DefaultChallengeScheme = "oidc";
})
.AddCookie("Cookies")
.AddOpenIdConnect("oidc", options =>
{
    options.Authority = "http://localhost:5010";
    options.RequireHttpsMetadata = false;
    options.ClientId = "mvc";
    options.ClientSecret = "client secret".ToSha256();
    options.SaveTokens = true;
    options.CallbackPath = "/signin-oidc";                
});  

i have added app.UseAuthentication() to configure method

然后，我可以在应用程序中预览PDF。

我想要类似的XLSX或XLS文件。

如果我点击url，我会得到文件，但无法显示。

我尝试过

var $obj = $('<object>');
$obj.attr("type", "application/pdf");
$obj.attr("data", myurl);                            
$("#id").append($obj);

但不起作用。

有什么想法吗？
