将哈希数组转换为 json [英] Convert array of hashes to json

问题描述

我想转换我这样创建的哈希数组:

I want to convert an array of hashes that I create like this:

while(...)
{
    ...
    push(@ranks, {id => $id, time => $time});
}

到 JSON:

use JSON;
$j = new JSON;
print $j->encode_json({ranks => @ranks});

但它输出的是:

{"ranks":{"time":"3","id":"tiago"},
 "HASH(0x905bf70)":{"time":"10","id":"bla"}}

如您所见，它无法写入散列并且没有数组...

As you can see it isnt able to write on of the hashes and there's no array...

我想输出如下所示的 JSON 字符串:

I would like to output a JSON string that looked like this:

 {"ranks":[{"time":"3","id":"tiago"},
           {"time":"40","id":"fhddhf"},
           {"time":"10","id":"bla"}]}

推荐答案

print $j->encode_json({ranks => @ranks});

应该是:

print $j->encode_json({ranks => \@ranks});
