如何从客户端从屏幕截图中进行此查询。

这是我尝试进行查询的方式，但是我不知道该怎么做，

const CategoriesProducts = async ()=>{
const fetchData = await API.graphql({
    query: listProductCategories, variables: {id: '1cb76030-0ee0-432a-b3ee-4087d33eaaf3'}
})
setCategoryProduct(fetchData.data.listProductCategories.items)}

这是我的架构

”查询

这是ListProductCategories查询

当我在TE AWS Console中进行查询时，我获得了结果，但是我无法在Visual Studio Code中执行相同的查询

谢谢您的支持

在您的GraphQL目录中由AWS-CLI自动生成，创建新文件，casure-ceries.js：

- graphql/
  - mutations.js
  - subscriptions.js
  - queries.js
  - custom-queries.js << Create this new file

定义以下自定义gruber graphql查询code> code> code-queries.js：

 export const ListProductCategoriesByCategoryId = /* Graphql */ `
    query listProductCategories(
      $filter = ModelProductCategoryFilterInput
       ){
         listProductCategories( filter : $filter) {
           items {
              product {
                        price
                        image
                        id
                        title
                      }
                }
          }
        }
    `;

现在您应该能够在代码中导入list ProductCategoriesByCategoryId ，并以此为单位：

   import { API, graphqlOperation } from 'aws-amplify';
   import { ListProductCategoriesByCategoryId } from '../custom-queries.js';
.
.
.
   const fetchData = await API.graphql(
    graphqlOperation(
     ListProductCategoriesByCategoryId, 
           { filter : { categoryID : { eq : "1cb76....." }}
     )
   );
   console.log(fetchData);

In your graphql directory auto-generated by aws-cli, create new file, custom-queries.js :

- graphql/
  - mutations.js
  - subscriptions.js
  - queries.js
  - custom-queries.js << Create this new file

define the following custom graphql query inside custom-queries.js :

 export const ListProductCategoriesByCategoryId = /* Graphql */ `
    query listProductCategories(
      $filter = ModelProductCategoryFilterInput
       ){
         listProductCategories( filter : $filter) {
           items {
              product {
                        price
                        image
                        id
                        title
                      }
                }
          }
        }
    `;

Now you should be able to import ListProductCategoriesByCategoryId in your code and call it like this :

   import { API, graphqlOperation } from 'aws-amplify';
   import { ListProductCategoriesByCategoryId } from '../custom-queries.js';
.
.
.
   const fetchData = await API.graphql(
    graphqlOperation(
     ListProductCategoriesByCategoryId, 
           { filter : { categoryID : { eq : "1cb76....." }}
     )
   );
   console.log(fetchData);
