使用Firebase CLI选择文档

要了解的选项 database:get 命令,运行 firebase database:get --help 如:

% firebase database:get --help
Usage: firebase database:get [options] <path>

fetch and print JSON data at the specified path

Options:
  -o, --output <filename>  save output to the specified file
  --pretty                 pretty print response
  --shallow                return shallow response
  --export                 include priorities in the output response
  --order-by <key>         select a child key by which to order results
  --order-by-key           order by key name
  --order-by-value         order by primitive value
  --limit-to-first <num>   limit to the first <num> results
  --limit-to-last <num>    limit to the last <num> results
  --start-at <val>         start results at <val> (based on specified ordering)
  --end-at <val>           end results at <val> (based on specified ordering)
  --equal-to <val>         restrict results to <val> (based on specified ordering)
  --instance <instance>    use the database <instance>.firebaseio.com (if omitted, use default database instance)
  -h, --help               output usage information

因此,您可以通过以下方式获取您名称的所有子节点:

firebase database:get /users --order-by "name" --equal-to "Michael"

别忘了 define an index 在你的规则中代表“名字”。
