如何使用 python 脚本将 json 文件中的单引号转换为双引号。
文件名:strings.json 文件内容
[{'postId':'328e9497740b456154c636349','postTimestamp': '1521543600','pageType': '/home.php:topnews','viewTime': 1521545993647,'user_name': 'windows-super-user','gender': 3,'likes': '8','id': 'ffa1e07529ac917f6d573a','postImg': 1,'postDesc': [753],'origLink': 0,'duration': 0,'timestamp': 9936471521545,'back_time': 1521545993693},{'postId':'15545154c636349','postTimestamp': '547773600', 'pageType': '/home.php:topnews','viewTime': 45993647,'user_name': 'linux user','gender': 3,'likes': '8','id': '695e45a17f6d573a','postImg': 1,'postDesc': [953],'origLink': 0,'duration': 0,'timestamp': 545993647,'back_time': 85993693},{'postId':'9098897740b456154c636349','postTimestamp': '899943600', 'pageType': '/home.php:topnews','viewTime': 1521545993647,'user_name': 'unix_super_user','gender': 3,'likes': '8','id': '917f6d573a695e45affa1e07','postImg': 1,'postDesc': [253],'origLink': 0,'duration': 0,'timestamp': 193647,'back_time': 1521545993693}]
我已经尝试了以下代码，但它不起作用；
with open('strings.json') as f:
jstr = json.dump(f)
print(jstr)
预期输出:
[
{
"postId":"328e9497740b456154c636349",
"postTimestamp": "1521543600",

}
]
最佳答案
单引号对于 JSON 中的字符串无效，因此对于任何解析器而言，该文件都不是有效的 JSON。
如果您想用双引号替换所有单引号，只需执行以下操作:
# Read in the file contents as text
with open('strings.json') as f:
invalid_json = f.read()
# Replace all ' with "
valid_json = invalid_json.replace("'", '"')
# Verify that the JSON is valid now and this doesn't raise an exception
json.loads(valid_json)
# Save the modified text back to the file
with open('strings.json.fixed', 'w') as f:
f.write(valid_json)
