javax.servlet.http Interface HttpServletRequest
- All Superinterfaces:
- ServletRequest
- All Known Implementing Classes:
- HttpServletRequestWrapper
public interface HttpServletRequest
- extends ServletRequest
扩展
javax.servlet.ServletRequest
接口,为 HTTP servlet 提供请求信息。
servlet 容器创建 HttpServletRequest
对象,并将该对象作为参数传递给 servlet 的 service 方法(doGet
、doPost
,等等)。
Extends the ServletRequest
interface
to provide request information for HTTP servlets.
The servlet container creates an HttpServletRequest
object and passes it as an argument to the servlet's service
methods (doGet
, doPost
, etc).

but before the query string, and translates it to a real
path. Same as the value of the CGI variable PATH_TRANSLATED.
If the URL does not have any extra path information, this method returns

String
specifying the real path, ornull
if the URL does not have any extra path information
public String
getContextPath()
返回请求 URI 指示请求上下文的那一部分。请求 URI 中首先出现的总是上下文路径。路径以 "/" 字符开头但不以 "/" 字符结束。对于默认(根)上下文中的 servlet,此方法返回 ""。容器不会解码此字符串。
servlet 容器可能通过多个上下文路径匹配一个上下文。在这种情况下,此方法将返回该请求使用的实际上下文路径,该路径可能不同于 getContextPath()

It is possible that a servlet container may match a context by more than one context path. In such cases this method will return the actual context path used by the request and it may differ from the path returned by the
ServletContext.getContextPath()
method. The context path returned byServletContext.getContextPath()
should be considered as the prime or preferred context path of the application. - Returns:
- a
String
specifying the portion of the request URI that indicates the context of the request - See Also:

GET http://foo.bar/a.html HTTP/1.0 | /a.html | |
HEAD /xyz?a=b HTTP/1.1 | /xyz |

。
return |
包含 URL 从协议名称一直到查询字符串的那一部分的 String |
See also | getRequestURL |
getRequestURI
String getRequestURI()
- Returns the part of this request's URL from the protocol
name up to the query string in the first line of the HTTP request.
The web container does not decode this String.
For example:
First line of HTTP request Returned Value POST /some/path.html HTTP/1.1 /some/path.html GET http://foo.bar/a.html HTTP/1.0 /a.html HEAD /xyz?a=b HTTP/1.1 /xyz To reconstruct an URL with a scheme and host, use
HttpUtils.getRequestURL(javax.servlet.http.HttpServletRequest)
. - Returns:
- a
String
containing the part of the URL from the protocol name up to the query string - See Also:
HttpUtils.getRequestURL(javax.servlet.http.HttpServletRequest)
public StringBuffer
getRequestURL()
重新构造客户端用于发出请求的 URL。返回的 URL 包含一个协议、服务器名称、端口号、服务器路径,但是不包含查询字符串参数。
如果已经使用 javax.servlet.RequestDispatcher#forward
转发了此请求,则重新构造的 URL 中的服务器路径必须反映用于获取 RequestDispatcher 的路径,而不是客户端指定的服务器路径。
因为此方法返回 StringBuffer
而不是字符串,所以可以轻松地修改 URL,例如,可以追加查询参数。
此方法对于创建重定向消息和报告错误很有用。
return |
包含重新构造的 URL 的 StringBuffer 对象 |
getRequestURL
StringBuffer getRequestURL()
- Reconstructs the URL the client used to make the request.
The returned URL contains a protocol, server name, port
number, and server path, but it does not include query
string parameters.
If this request has been forwarded using
RequestDispatcher.forward(javax.servlet.ServletRequest, javax.servlet.ServletResponse)
, the server path in the reconstructed URL must reflect the path used to obtain the RequestDispatcher, and not the server path specified by the client.Because this method returns a
StringBuffer
, not a string, you can modify the URL easily, for example, to append query parameters.This method is useful for creating redirect messages and for reporting errors.
- Returns:
- a
StringBuffer
object containing the reconstructed URL
public String
getServletPath()
返回此请求调用 servlet 的 URL 部分。此路径以 "/" 字符开头,包括 servlet 名称或到 servlet 的路径,但不包括任何额外路径信息或查询字符串。返回的值与 CGI 变量 SCRIPT_NAME 的值相同。
如果用于处理此请求的 servlet 使用 "/*" 模式实现匹配,则此方法将返回一个空字符串 ("")。
return |
包含将被调用或解码的 servlet 的名称或路径的 String (如请求 URL 中指定的那样),如果用于处理请求的 servlet 使用 "/*" 模式实现匹配,则返回一个空字符串。 |
getServletPath
String getServletPath()
- Returns the part of this request's URL that calls
the servlet. This path starts with a "/" character
and includes either the servlet name or a path to
the servlet, but does not include any extra path
information or a query string. Same as the value of
the CGI variable SCRIPT_NAME.
This method will return an empty string ("") if the servlet used to process this request was matched using the "/*" pattern.
- Returns:
- a
String
containing the name or path of the servlet being called, as specified in the request URL, decoded, or an empty string if the servlet used to process the request is matched using the "/*" pattern.
public HttpSession
getSession(boolean create)
返回与此请求关联的当前 HttpSession
,如果没有当前会话并且 create
为 true,则返回一个新会话。
如果 create
为 false
并且该请求没有有效的 HttpSession
,则此方法返回 null
。
要确保会话得到适当维护,必须在提交响应之前调用此方法。如果容器正使用 cookie 维护会话完整性,并被要求在提交响应时创建新会话,则抛出 IllegalStateException。
create |
true 表示为此请求创建一个新会话(如有必要);false 表示返回 null (如果没有当前会话) |
return |
与此请求关联的 HttpSession ,如果 create 为 false ,并且该请求没有有效会话,则返回 null |
See also | getSession() |
getSession
HttpSession getSession(boolean create)
- Returns the current
HttpSession
associated with this request or, if there is no current session andcreate
is true, returns a new session.If
create

and the request has no validHttpSession

- Parameters:
create
-true
to create a new session for this request if necessary;false
to returnnull
