使用 HotChocolate 进行拼接时，如何重命名远程架构的类型？

这是我的场景。我有一个 GraphQL 网关，它使用以下代码将十几个左右的远程模式拼接在一起：

services.AddHttpClient(schema.TypeName, c => c.BaseAddress = new Uri(schema.Url));

public virtual void Add(IRequestExecutorBuilder builder, bool ignoreRootTypes = true)
{
    var type = this.GetType();
    builder.AddRemoteSchema(type.Name, ignoreRootTypes);
}

假设远程模式是不可变的。其中一个远程架构具有名为 Name 的类型。这似乎是一个保留关键字，因为在拼接过程中，我得到了异常：

有关更多详细信息，请查看 Errors 属性。
已添加具有相同键的项目。键：姓名

我可以通过将远程服务的 Name 类型修改为类似 PersonName 来纠正此错误，但是，正如我上面提到的，这些外部模式应该是不可变的。

有没有办法在网关级别抛出此异常之前重命名受限类型？

Here's my scenario. I have a GraphQL gateway that stitches a dozen or so remote schemas together, using the following code:

services.AddHttpClient(schema.TypeName, c => c.BaseAddress = new Uri(schema.Url));

public virtual void Add(IRequestExecutorBuilder builder, bool ignoreRootTypes = true)
{
    var type = this.GetType();
    builder.AddRemoteSchema(type.Name, ignoreRootTypes);
}

Assume that the remote schemas are immutable. One of the remote schemas has a type called Name. This appears to be a reserved keyword, because during stitching, I get the exception:

For more details look at the Errors property.
An item with the same key has already been added. Key: Name

I can correct this error by modifying the Name type of the remote service to be something like PersonName, however, as I mentioned above, these external schemas should be immutable.

Is there a way to rename a restricted type before this exception is thrown at the Gateway level?

continue

Add a call to RenameType:

public virtual void Add(IRequestExecutorBuilder builder, bool ignoreRootTypes = true)
{
    var type = this.GetType();
    builder.AddRemoteSchema(type.Name, ignoreRootTypes);
    builder.RenameType("Name", "PersonName", type.Name);
}

This will rename the incoming type from your remote schema to something else.
