英文:
too many parameters returned by Resolver.ModuleName
问题
我正在将单体架构拆分为微服务架构。
我已经这样做了，但是当我在当前代码库中构建代码时，出现了以下错误。
我们使用graphql-gophers库
panic: (Resolver).Dummy返回的参数过多
有人在使用golang进行graphql查询时见过这个错误吗？
尝试了很多方法，但都没有成功。
任何帮助将不胜感激。
英文:
I am working on breaking the monolithic architecture into Microservice architecture.
I did that but when I am building the code in my current repository I am getting this error.
We use graphql-gophers library
panic: too many parameters returned by (Resolver).Dummy
Has anyone ever seen this error in golang using graphql for querying?
Tried so many things but nothing has worked.
Any help would be appreciated

错误消息来自graph-gophers/graphql-go internal/exec/resolvable/resolvable.go#makeFieldExec。
当解析的模式与现有结构的字段不匹配时，会调用该函数。
在example/customerrors/starwars.go中的示例中，每个字段都匹配，不会触发错误消息：
var Schema = `
schema {
query: Query
}
type Query {
droid(id: ID!): Droid!
}
# An autonomous mechanical character in the Star Wars universe
type Droid {
# The ID of the droid
id: ID!
# What others call this droid
name: String!
}
`
type droid struct {
ID graphql.ID
Name string
}
其解析器使用了正确的参数：
type Resolver struct{}
func (r *Resolver) Droid(args struct{ ID graphql.ID }) (*droidResolver, error) {
if d := droidData[args.ID]; d != nil {
return &droidResolver{d: d}, nil
}
return nil, &droidNotFoundError{Code: "NotFound", Message: "This is not the droid you are looking for"}
}
尝试使用该示例检查是否正常工作，然后根据自己的代码进行修改。
英文:
The error message comes from graph-gophers/graphql-go internal/exec/resolvable/resolvable.go#makeFieldExec
It is called when you parse a schema which does not match the field of an existing struct.
The one illustrated in example/customerrors/starwars.go does match every field and would not trigger the error message:
var Schema = `
schema {
query: Query
}
type Query {
droid(id: ID!): Droid!
}
# An autonomous mechanical character in the Star Wars universe
type Droid {
# The ID of the droid
id: ID!
# What others call this droid
name: String!
}
`
type droid struct {
ID graphql.ID
Name string
}
Its resolver does use the right parameters:
type Resolver struct{}
func (r *Resolver) Droid(args struct{ ID graphql.ID }) (*droidResolver, error) {
if d := droidData[args.ID]; d != nil {
return &droidResolver{d: d}, nil
}
return nil, &droidNotFoundError{Code: "NotFound", Message: "This is not the droid you are looking for"}
}
Try and use that example to check it does work, then modify it to transition to your own code.
