json - 通过 Postman 使用 PUT 请求更新 Contentful 帖子

Question

我正在尝试使用 Postman 更新 Contentful 条目。

我做了什么:

• 在 Contentful 空间中，我创建了一个测试帖子来玩。
• 转到设置 - API key - 内容管理 token 并生成个人访问 token
• 在 Postman 中创建 GET 请求，传递空间 ID、主环境和测试帖子的 ID:

https://cdn.contentful.com/spaces/{spaceID}i/environments/master/entries?sys.id={postID} 我还发送了带有内容交付 token 的授权 header 。

GET 请求成功，我能够复制 JSON 对象响应。

          "contentType": "image/png"
        }
      }
    }
  ]
}
}

现在我想创建 PUT 请求以将更新后的 JSON 发送到 Contentful。 我将收到的 JSON 粘贴为 GET 请求的响应。 我更改其中一个值:

"name": "测试入口" 到 "name": "测试条目 123"

我将 PUT 请求发送到 https://api.contentful.com/spaces/{spaceID}/environments/master/entries/{postID}

授权 header 包含我之前生成的个人访问 token 。 X-Contentful-Version header 包含帖子的版本，可以在帖子详细信息中找到

当我发送此请求时，我收到带有空“字段”的 JSON 响应:{}

{
  "metadata": {
  "tags": []
},
  "sys": {
  "space": {
    "sys": {
      "type": "Link",
        "linkType": "Space",
        "id": "d9r4mg123x4v"
    }
  },
  "id": "2Fwow39hxxx1bvMkjpsyV9",
    "type": "Entry",
    "createdAt": "2021-11-10T13:57:10.882Z",
    "updatedAt": "2021-11-11T10:58:39.480Z",
    "environment": {
    "sys": {
      "id": "master",
        "type": "Link",
        "linkType": "Environment"
    }
  },
  "publishedVersion": 13,
    "publishedAt": "2021-11-10T14:06:51.393Z",
    "firstPublishedAt": "2021-11-10T14:00:11.935Z",
    "createdBy": {
    "sys": {
      "type": "Link",
        "linkType": "User",
        "id": "4123123123zOn3MkhuVB"
    }
  },
  "updatedBy": {
    "sys": {
      "type": "Link",
        "linkType": "User",
        "id": "4123123123zOn3MkhuVB"
    }
  },
  "publishedCounter": 3,
    "version": 23,
    "publishedBy": {
    "sys": {
      "type": "Link",
        "linkType": "User",
        "id": "4123123123zOn3MkhuVB"
    }
  },
  "contentType": {
    "sys": {
      "type": "Link",
        "linkType": "ContentType",
        "id": "hotelInfo"
    }
  }
},
  "fields": {}
}

而在 Contentful Admin 区域，帖子的所有字段都变为空。

内容丰富的文档说:

Contentful doesn't merge changes made to content, so when updating content, you need to send the entire body of an entry. If you update content with a subset of properties, you will lose all existing properties not included in that update.

You should always update resources in the following order:

• Fetch current resource.
• Make changes to the current resource.
• Update the resource by passing the changed resource along with current version number.

This way no unseen changes are overridden and unexpected conflicts are unlikely to occur.

Note: You can't update any of the sys property fields, including sys.id.

...所以，我想，我做的一切都是对的——接受帖子、编辑数据并发回更新后的帖子。 我尝试编辑我的 JSON 数据以在没有 sys 字段的情况下发送它，但没有成功。 我被卡住了，有人知道我应该继续做什么吗？

感谢@whitep4nth3r 我能够解决这个问题。 我需要从我试图将其放入的同一来源获取数据。 授权 header 需要替换为用于 PUT 请求的个人访问 token 。
