问题描述
GET请求的长度是否受到限制?
Is there a limit to the length of a GET request?
推荐答案
Not in the RFC, no, but there are practical limits.
HTTP协议没有对长度限制进行任何先验限制 URI.服务器必须能够处理其任何资源的URI 服务，并且应该能够处理长度不受限制的URI 提供可以生成此类URI的基于GET的表单.一台服务器 如果URI较长，则应返回414(请求URI太长)状态 超出服务器的处理能力(请参阅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).
注意:服务器应谨慎对待，具体取决于URI的长度 255字节以上，因为某些较旧的客户端或代理实现 可能无法正确支持这些长度.
Note: Servers should be cautious about depending on URI lengths above 255 bytes, because some older client or proxy implementations may not properly support these lengths.
