使用keystone-storage-adapter-s3后的字段错误

Question

我正在使用npm包keystone-storage-adapter-s3。在某种情况下，我试图将图像上传到AWS S3桶，然后使用Keystone CMS检索它们作为网站内容的一部分。我对AWS S3相当陌生，但正在尝试。

下面是有问题的图像模型。

const keystone = require('keystone');
const Types = keystone.Field.Types;

const Image = new keystone.List('Image');

const storage = new keystone.Storage({
    adapter: require('keystone-storage-adapter-s3'),
    s3: {
        key: process.env.S3_KEY, // required; defaults to process.env.S3_KEY
        secret: process.env.S3_SECRET, // required; defaults to process.env.S3_SECRET
        bucket: process.env.S3_BUCKET, // required; defaults to process.env.S3_BUCKET
        region: process.env.S3_REGION, // optional; defaults to process.env.S3_REGION, or if that's not specified, us-east-1
        uploadParams: { // optional; add S3 upload params; see below for details
          ACL: 'public-read',
        },
    },
    schema: {
        bucket: true, // optional; store the bucket the file was uploaded to in your db
        etag: true, // optional; store the etag for the resource
        path: true, // optional; store the path of the file in your db
        url: true, // optional; generate & store a public URL
    },
});

Image.add({
    name: { type: String },
    file: { type: Types.File, storage: storage },
});

Image.register();

我相信我已经填写了区域、桶名、secret（随机安全字符串），甚至创建了一个新的密钥，该密钥也安全地存储在。env文件中。

• “字段错误”
• 上载s3文件中的字段错误

我在node_modules/keystone/fields/types/file/filetype.js中找到了正在使用的调试包，并启用了它。我在尝试上载映像时收到以下调试消息。

这条消息看起来很有希望，所以我将继续查看这条消息，看看是否可以调试更多信息。

搜索还在继续。

Answer 1

我把我的“钥匙”和“秘密”搞混了。

根据keystone-storage-adapter-s3包，需要您的“密钥”和“秘密”。由于对AWS和web开发缺乏经验，我认为秘密是一个随机的安全字符串（就像你会用cookie签名一样），而密钥是我的秘密密钥。
