我在 PHP 中有以下代码:
$IDs = implode(",", array_keys($result["matches"]));
$sql = "SELECT * FROM table WHERE id IN ($IDs)";
我正在将它“翻译”成 Node.js,我想 implode 变成了 array.join,所以我尝试了这个:
var ids = Object.keys(answer['matches']).join(",");
var sql = "SELECT * FROM xml_it WHERE id IN (" + ids + ")";
现在,如果我回显 PHP $sql 变量,我会得到预期的结果:
SELECT * FROM table WHERE id IN (3187,3220,3233,3245,3246,3251,3253,3256, ...
但是,使用 node.js,我得到了这个:
SELECT * FROM xml_it WHERE id_xml IN ([0,1,2,3,4, ...
answer['matches'] 显然是相同的结果(它基本上是 Sphinx 搜索结果)
知道为什么我没有将它作为字符串而是键吗?
$result 和 var answer 的数据如下所示:
[{"doc":3187,"weight":1,"attrs":{}},{"doc":3220,"weight":1,"attrs":{}},{"doc":3233,"weight":1,"attrs":{}},
