Question

我有一个PHP脚本，该脚本处理REDIS以添加和获取数据：

$redis->hmset("post:1000", "product", "Red Shoes", "price", "5USD", "quantity", "2", "time", "02/02/2019");
$redis->hmset("post:2000", "product", "Yellow Shoes", "price", "5USD", "quantity", "2", "time", "02/02/2019");
$redis->hmset("post:3000", "product", "Pink Shoes", "price", "5USD", "quantity", "2", "time", "02/02/2019");
$redis->sadd("All_keys", array("post:1000", "post:2000", "post:3000"));

$key = "All_keys";
$keys = $redis->sort($key, array(
    'by' => 'nonsort',
    'get' => "post:*->price"
));

var_dump($keys);

但是不幸的是，这个回报：

array(3) { [0]=> NULL [1]=> NULL [2]=> NULL }

但是当我更改此设置时：

$keys = $redis->sort($key, array(
    'by' => 'nonsort',
    'get' => "post:*->price"
));

收件人：

$keys = $redis->sort($key, array(
    'by' => 'nonsort',
    'get' => "*->price"
));

这将正常返回价格：

array(3) { [0]=> string(4) "5USD" [1]=> string(4) "5USD" [2]=> string(4) "5USD" }

请问这种模式有什么问题？

post:*->price

由于我在那里看不到任何错误，因此应该能很好地工作。

欢迎您的帮助，谢谢。

REDIS使用“ GET post：*-> price”排序时返回空值
