是response.redirect总是一个http GET响应？ [英] is response.redirect always an http GET response?

问题描述

是response.redirect总是一个http GET响应？或者它可能是POST？....

解决方案

在大多数API中，标准重定向实现确实是每个定义得到。根据您熟悉的ASP.NET问题历史，我将为Java Servlet添加示例。

ASP.NET：

  Response.Redirect（http://google.com）; 
  

Servlet：

  response.sendRedirect是（ http://google.com）; 
  

它隐式设置响应状态为302， Location

当 current 请求是一个POST请求并且您想要使用POST重定向时，那么您需要307重定向。这不是由标准API提供的，但它通常只是设置适当的响应状态和标题。

ASP.NET：

  Response.Status =307临时重定向; 
 Response.AddHeader（Location，http://google.com）; 
  

Servlet：

  response.setStatus（307）; 
 response.setHeader（Location，http://google.com）; 
  

请注意，这将在请求最终用户确认的平均客户端上发出安全/确认警告发送POST数据到另一个位置。

is response.redirect always an http GET response? or it could be POST?....

解决方案

In most API's the standard redirect implementation does a 302 which is indeed per definition GET. As per your question history you're familiar with ASP.NET, I'll however add examples for Java Servlets as well.

ASP.NET:

Response.Redirect("http://google.com");

Servlet:

response.sendRedirect("http://google.com");

It implicitly sets the response status to 302 and the Location header to the given URL.

When the current request is a POST request and you want to redirect with POST, then you need a 307 redirect. This is not provided by the standard API, but it's usually just a matter of setting the appropriate response status and header.

ASP.NET:

Response.Status = "307 Temporary Redirect";
Response.AddHeader("Location", "http://google.com");

Servlet:

response.setStatus(307);
response.setHeader("Location", "http://google.com");

Note that this will issue a security/confirmation warning on the average client which requests the enduser for confirmation to send the POST data to another location.
