我一直在嘗試go-grapqhql，并且我已經能夠成功地創建一些架構，如下所示：type Artist struct { ID string `json:"id,omitempty"` Name string `json:"name"` Type string `json:"type"` Instrument []Instrument `json:"instrument"`}type Instrument struct{ Name string `json:"name"`}var artists = []Artist{ { ID: "1", Name: "Taylor Swift", Type: "artist", Instrument: []Instrument{ {Name:"violin"}, }, },}var instrumentType = graphql.NewObject(graphql.ObjectConfig{ Name: "Instrument", Fields: graphql.Fields{ "name": &graphql.Field{ Type: graphql.String, }, },})var artistType = graphql.NewObject(graphql.ObjectConfig{ Name: "Artist", Fields: graphql.Fields{ "id": &graphql.Field{ Type: graphql.String, }, "name": &graphql.Field{ Type: graphql.String, }, "type": &graphql.Field{ Type: graphql.String, }, "instrument": &graphql.Field{ Type: graphql.NewList(instrumentType), }, },})但是，當我嘗試用類似的結構做同樣的事情時......type Blk struct { Header Header `json:"header,omitempty"` Payload []Payload `json:"payload,omitempty"`}type Header struct { Parent string `json:"parent,omitempty"` Number int `json:"number,omitempty"` Nonce int `json:"nonce,omitempty"` Time int `json:"time,omitempty"` Miner string `json:"miner,omitempty"`}type Payloads []Payloadstype Payload struct { From string `json:"from,omitempty"` To string `json:"to,omitempty"` Value int `json:"value,omitempty"` Nonce int `json:"nonce,omitempty"` Data string `json:"data,omitempty"` Time int `json:"time,omitempty"` Signature string `json:"signature,omitempty"`}var blk = []Blk{ {Header: Header{ Parent: "0000000000000000000000000000000000000000000000000000000000000000", Number: 0, Nonce: 1548399560, Time: 1609374088, Miner: "0x699ecb24665b9734c420db0f75ed9677a8615eb1",

所以，我把 graphql 模式改成了：
var blockType = graphql.NewObject(
graphql.ObjectConfig{
Name: "block",
Fields: graphql.Fields{
"header" :&graphql.Field{
Type: headerType,
},
"payload": &graphql.Field{
Type: graphql.NewList(payloadType),
},
},
})
var payloadType = graphql.NewObject(
graphql.ObjectConfig{
Name: "payload",
Fields: graphql.Fields{
"from": &graphql.Field{
Type: graphql.String,
},
"to": &graphql.Field{
Type: graphql.String,
},
"value": &graphql.Field{
Type: graphql.Int,
},
"nonce": &graphql.Field{
Type: graphql.Int,
},
"data": &graphql.Field{
Type: graphql.String,
},
"time": &graphql.Field{
Type: graphql.Int,
},
"signature": &graphql.Field{
Type: graphql.String,
},
},
})
var headerType = graphql.NewObject(
graphql.ObjectConfig{
Name: "header",
Fields: graphql.Fields{
"parent": &graphql.Field{
Type: graphql.String,
},
"number": &graphql.Field{
Type: graphql.Int,
},
"nonce": &graphql.Field{
Type: graphql.Int,
},
"time": &graphql.Field{
Type: graphql.Int,
},
"miner": &graphql.Field{
Type: graphql.String,
},
},
},
)
現在，一切都按預期工作?？磥磉@句話是罪魁禍首：
"payload": &graphql.Field{
Type: graphql.NewList(transactionType),
},
出于某種原因，如果你嘗試做這種類型的嵌套go-graphql（或者graphql不知道該怎么做）。FWI：現在我的查詢看起來像這樣：
query{
blocks{header{parent,number,nonce,time,miner},payload{from,to,value,nonce,data,time,signature}}
}
并且它們會產生所需的結果。
