PUT /new.html HTTP/1.1Host: example.com
Content-type: text/html

回应

如果目标资源没有当前的表示,并且PUT请求成功创建一个,那么源服务器必须通过发送201Created)响应来通知用户代理。

HTTP/1.1 201 Created
Content-Location: /new.html

如果目标资源确实具有当前的表示形式,并且根据所包含表示的状态成功修改了表示形式,则源服务器必须发送200OK)或204No Content)响应以指示请求的成功完成。

HTTP/1.1 204 No Content
Content-Location: /existing.html
