我有一个简单的logstash管道：
input { stdin {}}
filter { json { source => "message" }}
output { stdout { codec => rubydebug }}
我发送简单的JSON数据：
$ echo '{"foo": "bar", "bar": 1}' | bin/logstash -f /etc/logstash/conf.d/test.conf "--path.settings" "/etc/logstash"
Sending Logstash's logs to /usr/share/logstash/logs which is now configured via log4j2.properties

到目前为止一切顺利。但是当试图解析其键看起来像数组的数据时会出现问题：
$ echo '{"foo": "bar", "bar[0]": 1, "bar[1]": 2, "bar[2]": 3}' | bin/logstash -f /etc/logstash/conf.d/test.conf "--path.settings" "/etc/logstash"

如何阻止logstash从JSON数据中解释字符串，最后得到：
{
"@version" => "1",
"host" => "xxxxxxx",
"bar[0]" => 1,
"bar[1]" => 2,
"bar[2]" => 3,
"@timestamp" => 2017-10-30T13:37:36.722Z,
"message" => "{\"foo\": \"bar\", \"bar[0]\": 1, \"bar[1]\": 2, \"bar[2]\": 3}",
"foo" => "bar"
}
更糟糕的是，如果我在“同一个键”上混合使用各种符号，则logstash会完全崩溃：
$ echo '{"foo": "bar", "bar": 1, "bar[1]": 2, "bar[2]": 3}' | bin/logstash -f /etc/logstash/conf.d/test.conf "--path.settings" "/etc/logstash"
