Solution to json object conversion error in python

Today, I encountered a problem in using json conversion in python: receiving a post json string: s {& amp; quot; username & amp; amp; quot;: & amp; quot; admin & amp; amp; quot;, & amp; quot; password & amp; quot ;: today, I encountered a problem in using json conversion in python:

Receives a post json string:

S = {"username": "admin", "password": "password", "tenantid ":""}

Use the json library that comes with python

import json>>> a=json.loads(s)Traceback (most recent call last):  File "
 
  ", line 1, in 
  
     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())TypeError: expected string or buffer>>>
  
 

Error!

Think twice about it. After debugging, it is found that the single quotation mark (') is used to represent the string "'" by default in python "'"

Therefore, after a string is used, python converts double quotation marks into single quotation marks.

>>> S = {"username": "admin", "password": "password", "tenantid ":""}

>>> Print s

{'Username': 'admin', 'password': 'Password', 'tenantid ':''}

Json does not support single quotes.

You can use the following method to convert

Json_string = json. dumps (s)

Python_obj = json. loads (json_string)

OK, problem solving
