英文:
What is '?' is meaning in url?
问题
在代码编写时，当我输入地震API链接时，我注意到链接中有一个'?'，然后我尝试查找关于它的信息，但没有进展。
像这样的URL中，'?' 的含义是什么：
https://earthquake.usgs.gov/fdsnws/event/1/query?starttime=2014-01-01&endtime=2014-01-02
我在其他网站上也看到过类似的情况，例如YouTube或Google，例如：'query?'、'watch?'、'count?'、'search?'：
https://www.youtube.com/watch?v=dQw4w9WgXcQ

'?'是URL中查询参数的起始符号。查询参数是附加到URL末尾的一组定义好的参数。它们是URL的扩展，用于根据传递的数据来定义特定的内容或操作。要将查询参数附加到URL的末尾，需要添加一个'?'，然后紧接着是查询参数。
英文:
The ? is the start of the query parameter in the URL. Query parameters are a defined set of parameters attached to the end of a URL. They are extensions of the URL that are used to help define specific content or actions based on the data being passed. To append query params to the end of a URL, a ‘?’ is added followed immediately by a query parameter.
