提交给 codeigniter 控制器的 url 解码错误
我有一个想要保存的 url，所以我将 jquery ajax 发布到控制器，我可以看到该帖子是 http://www.nailsupplies.us/products/ ESSIE%252dMatte-About-You-0.5oz..html 但当简单返回时$this->input->post('link'); 我明白了 http://www.nailsupplies.us/products/ ESSIE%2dMatte-About-You-0.5oz..html
起初我以为这可能是一些疯狂的 XSS 过滤器，但即使将第二个参数设置为 false 也不影响这，并且执行 $_POST 也不会，那么这个问题到底是怎么回事呢？
重现 您可以通过访问 http://e-ønsker.dk 自行测试，然后单击“ Tilføj ønske” - 如果您单击左侧的链接链图标，插入 URL 并单击“GEM”（保存）按钮，您将看到 ajax 发布和响应，并且响应只是以下的输出$this->input->post()
如果有人想知道语言是丹麦语
I have a url that I want to save, so I have my jquery ajax post to a controller, and I can see that the post is
http://www.nailsupplies.us/products/ESSIE%252dMatte-About-You-0.5oz..html but when simply return $this->input->post('link');
I get
http://www.nailsupplies.us/products/ESSIE%2dMatte-About-You-0.5oz..html
at first I thought it might be some crazy XSS filter, but even setting the second parameter false doesn't affect this, and doing a $_POST doesn't either so what the heck is up with this issue?
To reproduce
You can test it yourself by going to http://e-ønsker.dk and then click "Tilføj ønske" - if you then click the link-chain icon to the left, insert a URL and hit the "GEM" (save) button you will see both the ajax post and response, and the response is simply an output of $this->input->post()
And in case anynoe's wondering the language is danish

您似乎遇到了双重编码。
%25被解码为“%”，这是正确的。尝试避免在帖子之前对 URL 进行编码。您应该得到 http://www.nailsupplies.us/ products/ESSIE%2dMatte-About-You-0.5oz..html 它将正确解码为 http://www.nailsupplies.us/products/ESSIE-Matte -About-You-0.5oz..html (
%2d=-)。如果没有看到您的客户端脚本，我无法提供更多帮助。奇怪的是它只编码了第一个连字符而不是后面的连字符。
You seem to be experiencing double encoding.
%25is being decoded as '%' which is correct. Try avoiding encoding the URL before the post.You should get http://www.nailsupplies.us/products/ESSIE%2dMatte-About-You-0.5oz..html which will decode correctly to http://www.nailsupplies.us/products/ESSIE-Matte-About-You-0.5oz..html (
%2d=-).I can't help more without seeing your client side script. It's weird that it just encoded the first hyphen and not the following ones.
