Python URLLib/URLLib2开机自检 [英] Python URLLib / URLLib2 POST

问题描述

我正在尝试使用wx/Python创建超简单的虚拟输入/输出板.对于将要存储数据的服务器的请求之一，我已经准备好以下代码:

I'm trying to create a super-simplistic Virtual In / Out Board using wx/Python. I've got the following code in place for one of my requests to the server where I'll be storing the data:

data = urllib.urlencode({'q': 'Status'})
u = urllib2.urlopen('http://myserver/inout-tracker', data)
for line in u.readlines():
  print line

没什么特别的.我遇到的问题是，根据我阅读文档的方式，这应该执行发布请求"，因为我已经提供了data参数，但这种情况没有发生.我在该网址的索引中包含以下代码:

Nothing special going on there. The problem I'm having is that, based on how I read the docs, this should perform a Post Request because I've provided the data parameter and that's not happening. I have this code in the index for that url:

if (!isset($_POST['q'])) { die ('No action specified'); }
echo $_POST['q'];

每次我运行Python应用程序时，都会在控制台上显示未指定操作"文本.我将尝试使用Request Objects来实现它，因为我已经看到了一些包含这些对象的演示，但是我想知道是否有人可以帮助我解释为什么我没有收到带有此代码的Post Request.谢谢！

And every time I run my Python App I get the 'No action specified' text printed to my console. I'm going to try to implement it using the Request Objects as I've seen a few demos that include those, but I'm wondering if anyone can help me explain why I don't get a Post Request with this code. Thanks!

此代码可以正常工作，并且可以正确地发布到我的网页上:

This code does work and Posts to my web page properly:

data = urllib.urlencode({'q': 'Status'})
h = httplib.HTTPConnection('myserver:8080')
headers = {"Content-type": "application/x-www-form-urlencoded", 
           "Accept": "text/plain"}
h.request('POST', '/inout-tracker/index.php', data, headers)
r = h.getresponse()
print r.read()

我仍然不确定为什么在提供data参数时urllib2库不发布-对于我来说文档指示应该如此.

I am still unsure why the urllib2 library doesn't Post when I provide the data parameter - to me the docs indicate that it should.

推荐答案

u = urllib2.urlopen('http://myserver/inout-tracker', data)
h.request('POST', '/inout-tracker/index.php', data, headers)

使用路径/inout-tracker不带尾随/不会获取index.php.相反，服务器将发布302重定向到带有尾随/的版本.

Using the path /inout-tracker without a trailing / doesn't fetch index.php. Instead the server will issue a 302 redirect to the version with the trailing /.

执行302通常会导致客户端将POST转换为GET请求.

Doing a 302 will typically cause clients to convert a POST to a GET request.
