http - 从 Web.py 中的 PUT 方法获取输入

Question

我在服务器程序中使用了以下代码:

class AddLibSong:
  def PUT(self):
  db = MahData.getDBConnection()
  songs = json.loads(web.input().to_add)
  addToLibrary(songs)
  return

但出于某种原因，当我对数据进行 PUT 时:

"to_add=[ { "album" : "Unknonwn", "artist" : "Unknonwn", "host_lib_id" : "1", "is_deleted" :
"false", "server_lib_id" : "-1", "song" : "Moneytalks" } ]" 

我收到以下错误:

Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/web/application.py", line 237, in process
    return self.handle()
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/web/application.py", line 228, in handle
    return self._delegate(fn, self.fvars, args)

    raise AttributeError, k

127.0.0.1:51096 - - [29/Sep/2011 19:02:58] "HTTP/1.1 PUT /add_songs_to_library" - 500 Internal Server Error

有人知道这是为什么吗？我想我看到了一些关于 Web.py 的内容，如果给定 POST 或 GET，开始只能获取输入，但我在源代码中没有看到任何应该阻止这种情况的内容。

无论如何，如果您想了解有关如何将 PUT 与 WebPy 结合使用的更多详细信息，我会建议您 this很棒的链接。

要使其在最新版本的 webpy 上运行，您应该将“主要”代码更改为:

if __name__ == "__main__":

    app=web.application(urls, globals())
    app.run()
