您要获取路径段变量还是GET变量?看来您要兼而有之.

Are you trying to get a path segment variable or a GET variable? It looks like you're going for a bit of both.

在CI中，如果您将URL更新为更像

Natively in CI, you can use $this->input->get if you update your url to look more like

http://localhost/sitename/some-post-title/?code=24639204963309423

(注意问号).

或者，您可以将URL修改为这样

Alternatively, you can modify your URL to look like this

http://localhost/sitename/some-post-title/code/24639204963309423

然后像这样使用URI段

And then use URI segments like so

$data = $this->uri->uri_to_assoc();
$code = $data['code'];

如果您不想更改URL，则必须像这样手动拆分该字符串

If you do not want to change your URL, you will have to break that string up manually like so

$data = $this->uri->segment(3);
$data = explode($data, '=');
$code = $data[1];

我认为第二个选择是最SEO友好且最漂亮的解决方案.但是这些功能在功能上都应该相同.

I would argue the second option is the most SEO-friendly and pretty solution. But each of these should be functionally identical.
