[英]Subobject is not parsed graphql with golang
The object itself inside the object is parsed with an empty field. 对象内部的对象本身使用空字段进行解析。
input: 输入:
{
Products(search: {limit: 1, filters: {product_id: {gte: 5}}}) {
data {
product_id
product_name
sales_history{
total_check
}
}
}
}
output: 输出:
{
"data": {
"Products": {
"data": [
{
"product_id": 35,
"product_name": "testpr",
"sales_history": {}
}
]
}
}
}
Product type: 产品类别:
gql.ProductType = graphql.NewObject(graphql.ObjectConfig{
Name: "Product",
Fields: graphql.Fields{
"product_id": &graphql.Field{
Type: graphql.Int,
},
"product_name": &graphql.Field{
Type: graphql.String,
},
"sales_history": &graphql.Field{
Type: gql.SalesHistoryType,
},
},
})
SalesHistory type: SalesHistory类型:
gql.SalesHistoryType = graphql.NewObject(graphql.ObjectConfig{
Name: "sales_history",
Fields: graphql.Fields{
"total_check": &graphql.Field{
Type: graphql.Float,
},
},
})
In Resolve returning map in interface: 在解析接口中的返回映射中:
map[data:[map[product_id:35 product_name:testpr sales_history:map[total_check:671.20]]]]
地图[数据:[地图[产品ID:35产品名称:testpr销售历史:地图[总计检查:671.20]]]]]
I create the map"sales_history" myself, otherwise opposite the field sales_history - null 我自己创建地图“ sales_history”,否则在字段sales_history对面-null
The problem was in the packaging of the final map. 问题出在最终地图的包装中。
It was wrong: 那是错的:
tmp := make(map[string]interface{}, 0)
tmp["total_check"] = v["total_check"]
v["sales_history"] = tmp
*Some fields are hidden *某些字段被隐藏
That`s right: 是的:
v["sales_history"] = make(map[string]interface{}, 0)
v["sales_history"].(map[string]interface{})["total_check"] = v["total_check"]
