HTTP 303（参见其他）：GET Works，POST失败 [英] HTTP 303 (SeeOther): GET Works, POST Fails

问题描述

我正在尝试执行一个简单的操作：

I am trying to perform a simple action:

1. POST到URL


2. 返回HTTP 303（参见其他）


3. 从新网址获取

据我所知，这个是一个非常标准的做法：
http://en.wikipedia.org/wiki /发布/重定向/获取

From what I can tell, this is a pretty standard practice: http://en.wikipedia.org/wiki/Post/Redirect/Get

此外，似乎SeeOther的设计工作方式如下：
http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html#sec10。 3.4

Also, it would seem that SeeOther is designed to work this way: http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html#sec10.3.4

我使用web.py作为我的服务器端控制器，但我怀疑这不是问题。如果我获得，SeeOther按预期完美无瑕地工作。如果我发布到同一个URL，则浏览器无法重定向或加载任何内容。

I'm using web.py as my server-side controller, but I suspect that it's not the issue. If I GET, SeeOther works flawlessly as expected. If I POST to the same URL, the browser fails to redirect or load anything at all.

认为这是浏览器问题，我尝试了IE9和谷歌浏览器（v23） ISH）。两者都有相同的问题。

Thinking it was a browser issue, I tried both IE9 and Google Chrome (v23 ish). Both have the same issue.

认为web.py可能正在错误地提供页面，或生成错误的URL，我使用telnet来检查标题。我发现了这个：

Thinking web.py might be serving the page incorrectly, or generating a bad URL, I used telnet to examine the headers. I found this:

HTTP GET（这在浏览器中有效）：

HTTP GET (this works in the browser):

GET /Users/1 HTTP/1.1
HOST: domain.com

HTTP/1.1 303 See Other
Date: Mon, 24 Dec 2012 18:07:55 GMT
Server: Apache/2
Cache-control: no-cache
Location: http://domain.com/Users
Content-Length: 0
Content-Type: text/html

HTTP POST（这在浏览器中不起作用）：

HTTP POST (this does not work in the browser):

POST /Users/1 HTTP/1.1
HOST: domain.com

HTTP/1.1 303 See Other
Date: Mon, 24 Dec 2012 18:12:35 GMT
Server: Apache/2
Cache-control: no-cache
Location: http://domain.com/Users
Content-Length: 0
Content-Type: text/html

另一件事可能会让工作变得棘手：
我正在使用mod-rewrite，以便用户可见的domain.com/Users/1实际上是domain.com/control.py/Users / 1

Another thing that could be throwing a wrench in the works: I'm using mod-rewrite so that the user-visible domain.com/Users/1 is actually domain.com/control.py/Users/1

可能有更多信息/故障排除我有，但我现在正在填空。

There may be more information/troubleshooting that I have, but I'm drawing a blank right now.

问题：

为什么这适用于GET请求，而不是POST请求？我在某个地方错过了回复标题吗？

Why does this work with a GET request, but not a POST request? Am I missing a response header somewhere?

编辑：

使用IE9开发人员工具和Chrome的Inspector，看起来303后POST不会回到浏览器。但是，当我发出GET请求时，我可以看到303进来。

Using IE9 Developer Tools and Chrome's Inspector, it looks like the 303 isn't coming back to the browser after a POST. However, I can see the 303 come in when I do a GET request.

然而，在仔细查看Chrome的Inspector后，我看到了记录每个请求的能力（不清楚每个页面调用）。这让我看到由于某种原因，我的POST请求看起来像是失败了。再次--GET工作正常。

However, after looking more closely at Chrome's Inspector, I saw the ability to log every request (don't clear w/ each page call). This allowed me to see that for some reason, my POST request looks like it's failing. Again - GET works just fine.

推荐答案

完全有可能这不是你的问题，但是因为你没有我发布了你的代码我将采取一些措施（以防万一）。

It's entirely possible that this isn't your issue, but since you don't have your code posted I'll take a shot (just in case).

由于您使用的是web.py，您是否在对象上定义了POST方法？

Since you're using web.py, do you have the POST method defined on your object?

ie

urls = (
    '/page', 'page'
)

class page:

    def POST(self):
        # Do something

    def GET(self):
        # Do something else
