带有问号的URI段 [英] URI Segment with Question Mark

问题描述

对于我的休息WebService我需要一些变化，把城市或区域或其他东西。所以我的URI应该是这样：

For my Rest WebService I need some variations to put the city or Region or something else in it. So my URI should look like this:

/rest/rating/locations?city=London

现在我使用以下函数获取最后一个URI段：

Now I'm using following functions to get the last URI Segment:

$segcount = $this->uri->total_segments();
$lastseg = $this->uri->segment($segcount);

问题是来自问号的所有东西都被切割了！
保存的变量只是：locations

The Problem is here that everthing from the Question Mark gets cutted! The variable which gets saved is just: locations

我已经尝试在config.php配置以下：

I've tried configure following in the config.php:

$config['uri_protocol'] = 'PATH_INFO';
$config['permitted_uri_chars'] = 'a-z 0-9~%.:_\-?';
$config['enable_query_strings'] = TRUE;

是否还有其他可能性用问号保存整个段？

Is there any other possibility to save the whole segment with the question mark?

推荐答案

首先，确保你有：

$config['allow_get_array'] = TRUE;

enable_query_strings 实际上是完全不同的

URI类仍然不能帮助你，你必须单独引用查询字符串。

The URI class still won't help you here, you'll have to refer to the query string separately.

$segcount = $this->uri->total_segments();
$lastseg = $this->uri->segment($segcount);

// Either of these should work
$query_string = http_build_query($this->input->get());
$query_string = $this->input->server('QUERY_STRING');

$lastseg_with_query = $lastseg.'?'.$query_string;
