有没有办法在@GraphqQuery方法中读取请求头

Question

我需要从我的graphql查询解析器中的请求头读取数据。

使用graphql-spqr库。

方法示例。

import io.leangen.graphql.annotations.*;
import io.leangen.graphql.spqr.spring.annotation.GraphQLApi;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

@GraphQLApi
@Component
public class ProjectQueryResolver{
    @GraphQLQuery
    public Project projects(@GraphqlArugment String projectId) {
        **// want to read authorization token present in request header**
        ...
    }
}

Answer 1

能够使用@GraphQLRootContext作为我的方法参数之一进行解析

import io.leangen.graphql.annotations.*;
import io.leangen.graphql.spqr.spring.annotation.GraphQLApi;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

@GraphQLApi
@Component
public class ProjectQueryResolver{
    @GraphQLQuery
    public Project projects(@GraphqlArugment String projectId, 
                            @GraphQLRootContext DefaultGlobalContext context) {

       HttpServletRequest servletRequest = context.getServletRequest();
       String paramValue = servletRequest.getHeader("param"); 
       ...
    }
}
