python - Python中的JSON解析错误

Question

这个问题已经有答案了:

Loading JSONL file as JSON objects (5 个回答)

已关闭 去年。

我正在使用 Python 2.7.6 解析 JSON 文件，但出现错误，但我不太确定原因。这是我第一次处理 Python，所以这可能是一个非常基本的问题，但我查看了一些堆栈溢出，似乎无法找出问题所在。

这是我解析数据的 python 代码:

import json
from pprint import pprint 

with open ('test.json') as data_file:
    data = json.load(data_file);
pprint(data)  

这是我的 JSON 文件:

{"votes": {"funny": 0, "useful": 0, "cool": 0}, "user_id": "hckr9Hf8BUHcXfOSDv9eJA", "review_id": "K6EEJo0I8AbwGWvwe5SJYQ", "stars": 5, "date": "2013-05-05", "text": "This place is fantastic. they have a restaurant inside the grocery store. very good food.", "type": "review", "business_id": "uPezkdNi_x_SwWlf_2rcMw"}
{"votes": {"funny": 0, "useful": 0, "cool": 1}, "user_id": "PK3TxomYLwZuOXonmYqjNw", "review_id": "5ivy-tczAQ4WYrmVF6YoKg", "stars": 5, "date": "2013-08-11", "text": "This is going to be a place we go back to many times!", "type": "review", "business_id": "UB2j_EV3CIM_E4LcpadKMQ"}

这是我解析 JSON 时遇到的错误:

File "./parse.py", line 6, in <module>
    data = json.load(data_file);
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/json/__init__.py", line 290, in load
    **kw)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/json/__init__.py", line 338, in loads
    return _default_decoder.decode(s)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/json/decoder.py", line 368, in decode
    raise ValueError(errmsg("Extra data", s, end, len(s)))
ValueError: Extra data: line 2 column 1 - line 3 column 1 (char 318 - 600)

奇怪的是，如果我只有第一行 JSON，我就可以成功解析数据。任何帮助理解错误并帮助我修复它的帮助将不胜感激。

这不是有效的 json - 你不能像这样将两个哈希值彼此相邻......尝试这样的事情。您会注意到我在中间放置了一个逗号，并将整组哈希值放入一个数组中。

[
   {
      "stars" : 5,
      "date" : "2013-05-05",
      "review_id" : "K6EEJo0I8AbwGWvwe5SJYQ",
      "text" : "This place is fantastic. they have a restaurant inside the grocery store. very good food.",
      "user_id" : "hckr9Hf8BUHcXfOSDv9eJA",
      "type" : "review",
      "votes" : {
