If I have a variable to pass through a url and it has a question mark in it, do I just need to escape the question mark? If not how can I make sure it passes through like it's supposed to? Sorry if this is a simple question but I will need this info down the line and depending on the answer I might need to change stuff now that will be a mess if I go forward without knowing.
如果我有一个变量要通过一个url，它有一个问号，我需要转义问号吗?如果不是，我怎么能确保它像它应该的那样通过呢?抱歉，如果这是一个简单的问题，但我需要这个信息，根据我可能需要改变的答案，如果我继续下去而不知道，那将是一团糟。

A question mark URL encodes as %3F. But you should use a proper encoder for the whole thing rather than manually encoding a character.

Here's a full list of URL encoding characters. If you're using PHP for a server side language, you can use something like...
这是URL编码字符的完整列表。如果您使用PHP作为服务器端语言，您可以使用以下内容:
$nice_url = urlencode("http://your.old.url");
Other languages will have similar functions build in (or you can find one online). This will take care of your question mark (and other url issues).
其他语言也会内置类似的功能(或者你可以在网上找到)。这将处理您的问号(以及其他url问题)。

According to my experience of trying to make a JavaScript search engine that links to Google, just replace the question marks with %3F. A url reads the first two characters on the right of a % as hexadecimal format.
根据我的经验，尝试创建一个链接到谷歌的JavaScript搜索引擎，只需用%3F替换问号。url将以%为十六进制格式的右边的前两个字符读取。
