graphql - GraphQL 解析数据，用于响应

Question

如何返回成功执行的响应？结果对象已填充，但在尝试解析 result.Data 时出现递归错误。

> containerProperty)

我尝试了多个步骤，不确定我错过了什么？似乎这很简单。

public async Task<IActionResult> Post([FromBody] GraphQLQuery query)
{
    //var inputs = query.Variables.ToInputs();
    //Inputs inputs = new Inputs(null);

    var result = await new DocumentExecuter().ExecuteAsync(_ =>
    {
        _.Schema = _weatherSchema;
        _.Query = query.Query;
        _.OperationName = query.OperationName;
        //_.Inputs = inputs;
    });

    var opt = new JsonSerializerOptions()
    {
        WriteIndented = true,
        MaxDepth = 4,
        PropertyNameCaseInsensitive = true
    };

    //var json = await new DocumentWriter(opt).WriteToStringAsync(result.Data);

    var json = JsonConvert.SerializeObject(
        result.Data,
        Formatting.Indented,
        new JsonSerializerSettings
        {
            ContractResolver = new CamelCasePropertyNamesContractResolver()
        });

    return Content(json, "application/json");

}

谢谢
