Detailed documentation on the GraphQL binding component

配置

To setup GraphQL binding create a component of type bindings.graphql. 请参阅本指南，了解如何创建和应用绑定配置。 To separate normal config settings (e.g. endpoint) from headers, “header:” is used a prefix on the header names.

apiVersion: dapr.io/v1alpha1
kind: Component
metadata:
  name: example.bindings.graphql
spec:
  type: bindings.graphql
  version: v1
  metadata:
    - name: endpoint
      value:  http://localhost:8080/v1/graphql
    - name: header:x-hasura-access-key
      value: adminkey
    - name: header:Cache-Control
      value: no-cache
