Question

我试图阅读我从网站上抓取到Python中的JSON文件，最终目的是将其转换为csv文件，以便以后进行统计分析。

我想要阅读的文件的一个例子是：

globals.jsonpCallback('/feed/match/1-1-8vOt3JMq-1-2-yj0a9.dat', {"s":1,"d":{"bt":1,"sc":2,"st":{"notice":"finished","status-name":"Finished","result-name":"<p id=\"event-status\"

我当前的代码看起来像这样（以前的复制和粘贴作业是莫名其妙的错误）：

import json
from pprint import pprint

json_data = open('/home/readejj/Documents/data/1-1-jFEwehyT-1-2-yjaf9.dat').read()
json_stuff = json_data[json_data.find('{'):json_data.rfind('}')+1]
json_stuff = json_stuff.replace("\"","'")
print "json_stuff",type(json_stuff), len(json_stuff), json_stuff[1:2000]
d = json.loads(json_stuff)
pprint(d)

这是从Reading JSON from a file?

采用的

我得到的错误是：

Traceback (most recent call last):
  File "read_json.py", line 16, in <module>
    d = json.loads(json_stuff)
  File "/usr/lib/python2.7/json/__init__.py", line 326, in loads
    return _default_decoder.decode(s)
  File "/usr/lib/python2.7/json/decoder.py", line 366, in decode
    obj, end = self.raw_decode(s, idx=_w(s, 0).end())
  File "/usr/lib/python2.7/json/decoder.py", line 382, in raw_decode
    obj, end = self.scan_once(s, idx)
ValueError: Expecting property name: line 1 column 1 (char 1)

如果有人能提供帮助，我将不胜感激 - 如果这是一个非常基本的错误，我表示道歉，我不是一位经验丰富的程序员。

更新：已经指出我的替换线是坏的 - 如果删除，我会得到一个不同的错误：

Traceback (most recent call last):
  File "read_oddsportal_json.py", line 19, in <module>
    d = json.loads(json_stuff)
  File "/usr/lib/python2.7/json/__init__.py", line 326, in loads
    return _default_decoder.decode(s)
  File "/usr/lib/python2.7/json/decoder.py", line 366, in decode
    obj, end = self.raw_decode(s, idx=_w(s, 0).end())
  File "/usr/lib/python2.7/json/decoder.py", line 382, in raw_decode
    obj, end = self.scan_once(s, idx)
ValueError: Expecting , delimiter: line 1 column 99 (char 99)

Answer 1

这一行：

json_stuff = json_stuff.replace("\"","'")

很糟糕。删除它。

JSON规范要求字符串是双引号（"）分隔的，而不是单引号。

将已删除的json文件读入python
