GraphQL.NET-结果中的扩展

Question

我开始使用GraphQL for.NET Core 3.1(https://github.com/graphql-dotnet/graphql-dotnet)。我从网上看到的内容中构建了一个简单的例子(目前还没有太多关于它的信息(。

当我进行查询时，我会得到如下结果：

{
"data": {
"orders": [
{
"id": "e9c4325e-4d4c-42f6-963e-be1ad71a5b36",
"created": "2020-07-18"
},
{
"id": "12926137-cf6f-4b53-8848-443659e50823",
"created": "2020-07-18"
},
{
"id": "3c0d782d-15b1-474d-8ca9-01e33dad8e00",
"created": "2020-07-19"
},
{
"id": "befbcd57-7814-4134-9f17-fb45672e44c0",
"created": "2020-07-19"
}
]
},
"extensions": {
"tracing": {
"Version": 1,
"StartTime": "2020-07-18T19:45:15.5554022Z",
"EndTime": "2020-07-18T19:45:15.6044022Z",
"Duration": 49108500,
"Parsing": {
"StartOffset": 16700,
"Duration": 1102700
},
"Validation": {
"StartOffset": 1131500,
"Duration": 421899
},
"Execution": {
"Resolvers": [
{
"Path": [
"orders"
],
"ParentType": "Query",
"FieldName": "orders",
"ReturnType": "[OrderType]",
"StartOffset": 1756600,
"Duration": 45168300
},
{
"Path": [
"orders",
0,
"id"
],
"ParentType": "OrderType",
"FieldName": "id",
"ReturnType": "String!",
"StartOffset": 46995100,
"Duration": 79099
},
{
"Path": [
"orders",
0,
"created"
],
"ParentType": "OrderType",
"FieldName": "created",
"ReturnType": "Date!",
"StartOffset": 47081299,
"Duration": 219500
},
{
"Path": [
"orders",
1,
"id"
],
"ParentType": "OrderType",
"FieldName": "id",
"ReturnType": "String!",
"StartOffset": 47313299,
"Duration": 6199
},
{
"Path": [
"orders",
1,
"created"
],
"ParentType": "OrderType",
"FieldName": "created",
"ReturnType": "Date!",
"StartOffset": 47322400,
"Duration": 4599
},
{
"Path": [
"orders",
2,
"id"
],
"ParentType": "OrderType",
"FieldName": "id",
"ReturnType": "String!",
"StartOffset": 47329300,
"Duration": 599
},
{
"Path": [
"orders",
2,
"created"
],
"ParentType": "OrderType",
"FieldName": "created",
"ReturnType": "Date!",
"StartOffset": 47331600,
"Duration": 499
},
{
"Path": [
"orders",
3,
"id"
],
"ParentType": "OrderType",
"FieldName": "id",
"ReturnType": "String!",
"StartOffset": 47333799,
"Duration": 400
},
{
"Path": [
"orders",
3,
"created"
],
"ParentType": "OrderType",
"FieldName": "created",
"ReturnType": "Date!",
"StartOffset": 47335900,
"Duration": 399
}
]
}
}
}
}

这是我的问题：

query {
orders {
id,
created
}
}

为什么我在响应对象上得到extensions？我在任何例子中都没有看到过这种情况，而且它比"数据"结果本身更大——这违背了GraphQL保存数据传输的目的之一。

Answer 1

配置服务时，请检查是否设置了选项。EnableMetrics为false，如下所示：

services.AddGraphQL(options =>
{
options.EnableMetrics = false;
options.ExposeExceptions = true;

}).AddSystemTextJson(deserializerSettings => { }, serializerSettings => { })
.AddWebSockets()
.AddDataLoader()
.AddGraphTypes(typeof(ItemSchema));

这应该会去掉扩展数据。
