建议HTTPS单独设置开关而非根据endpoint来解析

根据README中的示例配置：

    "aws-s3": {
      "accessKeyID": "xxx",
      "secretAccessKey": "xxxxx",
      "bucketName": "my-bucket",
      "uploadPath": "{year}/{md5}.{extName}",
      "endpoint": "s3.us-west-000.backblazeb2.com",
      "urlPrefix": "https://img.example.com/"
    }

会导致上传失败。错误日志如下：

反复检查，关键配置参数填的都没问题。然后想是不是网络问题。打开Clash日志查看，发现上传时走的端口是80。但是Backblaze B2是禁止http访问的，必须走https（同样的，在Cloudflare里面需要把SSL设置为【严格】)。然后进入src/uploader.ts中查看，发现如下代码：

try {
    const u = url.parse(opts.endpoint)
    sslEnabled = u.protocol === "https:"
  } catch {
    // eslint-disable-next-line no-empty
  }
  const http = sslEnabled ? require(["https"](https://nodejs.org/api/https.html)) : require(["http"](https://nodejs.org/api/http.html))

发现走不走443端口是根据endpoint配置来的。parse出来是https才走443。然后把端口前面加上https://才能正常上传。这感觉不太符合直觉。因为S3的URL是这样的：

https://your-bucket-name.s3.s3.us-west-004.backblazeb2.com/xxxxxx

上传的url的hostname前面是加上了bucketName的。不是直接与https://相连。建议像bucketEndpoint一样给个开关来控制，不要根据url去parse。

以上。
