我正在嘗試使用 Hot Chocolate 12.3.2 在 .NET 中實作一個 GraphQL API。我能夠讓專案構建和運行。嘗試測驗我的查詢 CakePop 時，瀏覽器加載正常，但不存在模式。
startup.cs
namespace Application
{
public class Startup

public Startup(IConfiguration configuration)

Configuration = configuration;

public IConfiguration Configuration { get; }
// This method gets called by the runtime. Use this method to add services to the container.

public void ConfigureServices(IServiceCollection services)
{
services.AddGraphQLServer()
.AddQueryType<Query>()
.AddType<BillType>().AddGraphQL()
.BindRuntimeType<DateOnly, DateType>()
.AddTypeConverter<DateOnly, DateTime>(from => DateTime.Parse(from.ToString()))
.AddTypeConverter<DateTime, DateOnly>(from => DateOnly.FromDateTime(from));
services.AddGraphQL(sp => SchemaBuilder.New().AddServices(sp).Create())
.AddPooledDbContextFactory<WeVoteContext>(b =>b.UseInMemoryDatabase("Test"));
}
// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
if (env.IsDevelopment())

app.UseDeveloperExceptionPage();

app
.UseRouting()
.UseEndpoints(endpoints =>

uj5u.com熱心網友回復：
設定代碼似乎有問題……您正在混合舊 API 和新配置 API。
services
.AddPooledDbContextFactory<WeVoteContext>(b =>b.UseInMemoryDatabase("Test"))
.AddGraphQLServer()
.AddQueryType<Query>()
.AddType<BillType>()
.BindRuntimeType<DateOnly, DateType>()
.AddTypeConverter<DateOnly, DateTime>(from => from.ToDateTime(default))
.AddTypeConverter<DateTime, DateOnly>(from => DateOnly.FromDateTime(from.Date));
在 12.4.0-preview.8 中，我們提供了對TimeOnly和 的支持DateOnly。
當您移動到 ??12.4 時，請洗掉顯式系結和轉換器。
此外，您可以GraphQLIgnore再次使用此配置洗掉屬性。
