我正在关注 这个 github 存储库 和 这个答案。

在我的本地主机前端我有:
// Code I run on the frontend:
const s3 = new S3Client({
endpoint: 'https://s3.us-east-005.backblazeb2.com',
region: 'us-east-005',
credentials: {
accessKeyId: "5c83d2c9fb2a",
secretAccessKey: "0058d9a7de2103531f2f28e402f4bd5e7ad68d054c"
}
});
const x = await s3.send(new PutObjectCommand({
Bucket: "private-bucket2",
Key: "my-filename.jpg",
Body: blob
}));
我也尝试过 backblaze-b2 包
// Code I run on the frontend:
import B2 from "backblaze-b2";
const b2 = new B2({
applicationKeyId: '5c83d2c9fb2a', // or accountI: 'accountId'
applicationKey: '0058d9a7de2103531f2f28e402f4bd5e7ad68d054c' // or masterApplicationKey
});
await b2.authorize();
我明白了。

运行这个
./b2-windows update-bucket --cors-rules "$(cat rules.json)" profile-bucket
通过运行确认它有效:
./b2-windows get-bucket profile-bucket
创建应用程序密钥并记下 id 和密钥
// Insert keyId and appKey and the name of the bucket:
const key = {
keyId: "00xxxxxxxx9fb2030007",
appKey: "K00xxxxxxxbwuxxxxmsEyWbD/F4AxU",
bucket: "my-bucket"
}
const s3Client = new S3Client({
region,
endpoint,
credentials: {
accessKeyId: key.keyId,
secretAccessKey: key.appKey
}
});
const expiresIn = 7 * 24 * 60 * 60; // 3600
const command = new PutObjectCommand({ Bucket: key.bucket, Key: filename });
const signedUrl = await getSignedUrl(s3Client, command, { expiresIn })
await axios.put(signedUrl, file);
