即使輸入正確，Python JSON模塊也會出錯

Question

對於組項目，我必須使用python導入JSON對象。不好的一面是，即使JSON字符串正確（使用JSONLint檢查它），python仍然給我一條錯誤消息。該腳本我用它來測試，這是如下：

import json 

correct_json = """ { 
    "created_at": "Tue Feb 19 18:42:07 +0000 2013",

    "foo" : 5,\ 
    "bar" : ["spam", "eggs"] \ 
} """ 

print(json.dumps(json.loads(correct_json), sort_keys=True, indent=4 * ' ')) 

對不起，只是在尋求幫助，這麼大的JSON結構，但這塊的代碼已經被現磨我擋了一個多小時，我只是能不會發現錯誤。我希望一個訓練有素的JSON偵探能幫助我。錯誤蟒蛇給我的是：

D:\Documenten\Dropbox>python jsontest.py 
Traceback (most recent call last): 
    File "jsontest.py", line 99, in <module> 
    print(json.dumps(json.loads(correct_json), sort_keys=True, indent=4 * ' ')) 
    File "C:\Python33\lib\json\__init__.py", line 319, in loads 
    return _default_decoder.decode(s) 
    File "C:\Python33\lib\json\decoder.py", line 352, in decode 
    obj, end = self.raw_decode(s, idx=_w(s, 0).end()) 
    File "C:\Python33\lib\json\decoder.py", line 368, in raw_decode 
    obj, end = self.scan_once(s, idx) 
ValueError: Expecting ',' delimiter: line 6 column 25 (char 305) 

我使用Python 3，我可能失去了一些東西愚蠢的（它不會是第一次）。提前致謝！

它在這條線的雙重逃避問題：

"source": "<a href=\"http://twitterfeed.com\" rel=\"nofollow\"> twitterfeed </a>", 

在這種\"是越來越理解爲"，當你需要爲它仍然逃脫。所以你需要逃避轉義字符，就像\\"那樣它就變成了\"。

因此，解決方法是：

"source": "<a href=\\"http://twitterfeed.com\\" rel=\\"nofollow\\"> twitterfeed </a>", 

或者，宣告整個字符串作爲原始字符串，像這樣：

correct_json = r""" { 

但是，這會搞亂一些已經逃出序列。
