php - $_SERVER ['QUERY_STRING' ] 在 CodeIgniter 中不起作用

Question

在我的应用程序 url 之后？我无法访问完整的 URL
示例:www.examle.com/test.php?id=3通常我们可以得到像

$_GET['id'] = 3;

但在我的应用程序中它不起作用
所以我打印 $_SERVER 值。我的输出是

    [PHP_SELF] => /demo.php
    [REQUEST_TIME_FLOAT] => 1648028605.456
    [REQUEST_TIME] => 1648028605

这里也 [QUERY_STRING] => 是空的
但在另一个演示服务器中

[QUERY_STRING] => id=3

我可以知道主服务器不显示 query_string 的原因吗？

Application Version - CI 3
PHP version - 5.6

我也在使用 AWS centos 服务器

Answer 1

您可以启用查询字符串。

$this->config->set_item('enable_query_strings', TRUE);

实现此目的的一种简单方法是像这样解析服务器查询字符串。

$get_data = array();

parse_str($_SERVER['QUERY_STRING'], $get_data);

这会给你留下一个非常不安全的充满数据的数组，所以你应该使用 CI 的安全类来使其更安全；太喜欢了；

$get_data = $this->security->xss_clean($get_data);
