Question

我正在尝试加载json文件，但它发出错误。我的代码是：

    import json
    with open('test.json','r') as data_file:
           for line in data_file:
                   data = json.loads(line)
                   sub = ""
                   sub += data["author"]
                   print sub
    data_file.close()

test.json：

{
"link_flair_text": "Help",
"permalink": "/r/GlobalOffensive/comments/380nzf/question_on_regarding_operation_missions/",
"ups": 0,
"retrieved_on": 1440701267,

}

错误：

    Traceback (most recent call last):
      File "jsonfilter.py", line 5, in <module>
        data = json.loads(line)
      File "/usr/lib64/python2.7/json/__init__.py", line 338, in loads
        return _default_decoder.decode(s)
      File "/usr/lib64/python2.7/json/decoder.py", line 368, in decode
        raise ValueError(errmsg("Extra data", s, end, len(s)))
    ValueError: Extra data: line 1 column 6 - line 2 column 1 (char 5 - 2241)

我在python-2.7中执行它。所以请尽可能在python-2.7中提供解决方案。

即使在Python json.loads shows ValueError: Extra data有错误的解决方案，我也会问这个问题，因为如果我在该问题中使用解决方案，我将无法从数据中提取字段。

使用python加载json文件
