QueryString / GET / URL参数的限制

What is the limit on QueryString / GET / URL parameters

推荐答案

理论上没有限制。对于HTTP URL， HTTP 1.1规范声明：

There is no limit in theory. For HTTP URLs, the HTTP 1.1 specification states:

HTTP协议不对
a URI的长度设置任何先验限制。服务器必须能够处理它们所提供的任何资源的URI，并且如果它们是
提供可以生成这种URI的基于GET的表单，则应该能够处理无限长度的URI。如果URI比服务器可以处理的更长
，服务器
应该返回414（Request-URI Too Long）状态（参见第10.4.15节）。

The HTTP protocol does not place any a priori limit on the length of a URI. Servers MUST be able to handle the URI of any resource they serve, and SHOULD be able to handle URIs of unbounded length if they provide GET-based forms that could generate such URIs. A server SHOULD return 414 (Request-URI Too Long) status if a URI is longer than the server can handle (see section 10.4.15).

但实际上，许多客户端和服务器只支持一定长度的URL。 经验法则不允许使用超过2000个字符的网址（已编码百分比）考虑到了。）

But in practice, many clients and servers do only support URLs up to a certain length. The rule of thumb is not to use URLs longer than 2000 characters (percent encoding already taken into account).
