我需要幫助使用python的library.add_track功能（python last.fm api wrapper）

Question

我需要幫助調試嘗試在pylast中使用library.add_track函數時收到的錯誤。我已經檢查過代碼，但我不擅長python。我只是試圖利用這個包裝來添加一個軌道列表到我的圖書館。你可以在這裏找到pylast代碼：

http://code.google.com/p/pylast/source/browse/trunk/pylast.py

import pylast 

# You have to have your own unique two values for API_KEY and API_SECRET 
# Obtain yours from http://www.last.fm/api/account for Last.fm 
API_KEY = "your_key" 
API_SECRET = "your_secret" 

# In order to perform a write operation you need to authenticate yourself 
username = "username" 
password_hash = pylast.md5("password") 

network = pylast.LastFMNetwork(api_key = API_KEY, api_secret = 
    API_SECRET, username = username, password_hash = password_hash) 

# This is the area causing trouble 
library1 = pylast.Library(user = "Username", network = "LastFM") 
track1 = network.get_track("Rob Dougan", "Clubbed To Death (Kurayamino Variation)") 
library1.add_track(track1) 

我收到的錯誤是：

Traceback (most recent call last): 
    File "addTrack.py", line 18, in <module> 
    library1.add_track(track1) 
    File "/usr/local/lib/python2.6/dist-packages/pylast.py", line 1976, in add_track 
    self._request("library.addTrack", False, params) 
    File "/usr/local/lib/python2.6/dist-packages/pylast.py", line 970, in _request 
    return _Request(self.network, method_name, params).execute(cacheable) 
    File "/usr/local/lib/python2.6/dist-packages/pylast.py", line 715, in __init__ 
    (self.api_key, self.api_secret, self.session_key) = network._get_ws_auth() 
AttributeError: 'str' object has no attribute '_get_ws_auth' 

我欣賞的幫助。

UPDATE：

對於其他人具有pylast這個問題，我會後下一個正確的示例用於添加跟蹤到庫中。我將錯誤的網絡參數傳遞給pylast.Library（）。

修復上述問題後，代碼開始拋出缺少的參數錯誤。我不得不在library類的add_track（）函數中添加下面一行到pylast.py（1970行）。這是Last.fm API的必要參數。

params['artist'] = track.get_artist().get_name() 

工作實例添加曲目到用戶的庫：

import pylast 

# You have to have your own unique two values for API_KEY and API_SECRET 
# Obtain yours from http://www.last.fm/api/account for Last.fm 
API_KEY = "your_key" 
API_SECRET = "your_secret" 

# In order to perform a write operation you need to authenticate yourself 
username = "username" 
password_hash = pylast.md5("password") 

network = pylast.LastFMNetwork(api_key = API_KEY, api_secret = 
    API_SECRET, username = username, password_hash = password_hash) 

# Get the User's library 
library = pylast.Library(user = "username", network = network) 

# Add a track 
track = network.get_track("Rob Dougan", "Clubbed To Death (Kurayamino Variation)") 
library.add_track(track)
