推荐答案

在大多数 API 中，标准重定向实现执行 302，这确实是每个定义的 GET.根据您的问题历史记录，您对 ASP.NET 很熟悉，但我也会为 Java Servlet 添加示例.

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");

服务端:

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

它将响应状态隐式设置为 302，并将 Location 标头设置为给定的 URL.

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

当 current 请求是 POST 请求并且您想使用 POST 重定向时，那么您需要一个 307 重定向.这不是由标准 API 提供的，但通常只是设置适当的响应状态和标头的问题.

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");

服务端:

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

请注意，这将在普通客户端上发出安全/确认警告，请求最终用户确认将 POST 数据发送到另一个位置.

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.
