Question

我在服务器程序中使用以下代码：

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

但出于某些原因，当我使用数据进行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):

    return self.handle()

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？我想我看到一些关于Web.py的东西，只有在给出POST或GET时才能获得输入，但我没有在源代码中看到任何应该阻止它的内容。

无论如何，如果你想了解如何在WebPy上使用PUT的更多细节，我会建议你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()

从Web.py中的PUT方法获取输入
