推荐答案

在Codeigniter中，您可以轻松完成

In Codeigniter you can simply do

public function get_radius($lang)
{
   var_dump($lang); //will output "lang=123"
}

因此您的链接可以简化为 http：// localhost / directory / c_service / get_radius / 123 如果您不想执行 explode（'='，$ lang ）获取值。

So your link could be simplified to http://localhost/directory/c_service/get_radius/123 if you don't want to do something like explode('=', $lang) to get your value.

不过，您还应该考虑添加默认值公共函数get_radius（$ lang = 0）如果没有参数打开链接。

You should however also consider adding a default value public function get_radius($lang=0) if the link is opened without a parameter.

添加更多变量与公共函数get_radius（ $ lang，$ other） for http：// localhost / directory / c_service / get_radius / 123 / other

Adding more variables is as easy as public function get_radius($lang, $other) for http://localhost/directory/c_service/get_radius/123/other
