graphql - 在 Strapi GraphQL 查询中获取图像格式

Question

我有一个 Post内容类型，具有 FeaturedImage field 。由于此字段是图像上传，因此 Strapi 会生成方便的附加格式:thumbnail , small , medium和 large .
当我在 JSON 中查询所有帖子时，我在响应中得到这些格式:

{
  "id": 1,
  "Title": "Hello World",
  "Content": "Nullam id dolor id nibh ultricies vehicula ut id elit..",
  "FeaturedImage": {
    "id": 1,
    "name": "angel-jimenez-168185",
    "alternativeText": "",
    "caption": "",
    "width": 2768,
    "height": 1560,
    "formats": {
      "thumbnail": {
        "hash": "thumbnail_angel_jimenez_168185_aaceac7acf",
        "ext": ".jpeg",
        "mime": "image/jpeg",
        "width": 245,
        "height": 138,
        "size": 6.22,
        "path": null,
        "url": "/uploads/thumbnail_angel_jimenez_168185_aaceac7acf.jpeg"
      },
      "large": {
        "hash": "large_angel_jimenez_168185_aaceac7acf",
        "ext": ".jpeg",
        "mime": "image/jpeg",
        "width": 1000,
        "height": 564,
        "size": 75.71,
        "path": null,
        "url": "/uploads/large_angel_jimenez_168185_aaceac7acf.jpeg"
      },
      "medium": {
        "hash": "medium_angel_jimenez_168185_aaceac7acf",
        "ext": ".jpeg",
        "mime": "image/jpeg",
        "width": 750,
        "height": 423,
        "size": 41.8,
        "path": null,
        "url": "/uploads/medium_angel_jimenez_168185_aaceac7acf.jpeg"
      },
      "small": {
        "hash": "small_angel_jimenez_168185_aaceac7acf",
        "ext": ".jpeg",
        "mime": "image/jpeg",
        "width": 500,
        "height": 282,
        "size": 19.69,
        "path": null,
        "url": "/uploads/small_angel_jimenez_168185_aaceac7acf.jpeg"
      }
    }
  }
}

但是，如果我在 GraphQL 中查询，只有 publicURL对于原始(全尺寸)图像可用:

我如何使用 GraphQL 访问这些图像格式？

Answer 1

此查询向我显示了所有预期的格式对象:

query MyQuery {
  strapi {
    home {
      content {
        image {
          formats
        }
      }
    }
  }
}

我确实在trapi上明确安装了graphql插件
https://strapi.io/documentation/3.0.0-beta.x/plugins/graphql.html#usage
我在我的 api url 中使用/graphql(例如 http://localhost:1337/graphql)。
我希望有帮助，@jgthms
