How to validate a JSON string with escaped quotes using Python
问题
I am using json.loads to parse a JSON string. However, it identifies the string as invalid JSON when it contains escaped double quotes. Since the string itself is valid, how could I parse it correctly without modifying the input string (i.e. using \" instead of "). Here is my code:
import jsona = '{"name":"Nickname \\"John\\" Doe", "age":31, "Salary":25000}'print("initial strings given - \n", a)try:json_object1 = json.loads(a)print("Is valid json? true")except ValueError as e:print("Is valid json? false")

Since the backslash itself is an escape character, you need to either escape it, or use a raw string (simply with the "r" prefix):
a = '{ "name":"Nickname \"John\" Doe", "age":31, "Salary":25000}'
or
a = r'{ "name":"Nickname "John" Doe", "age":31, "Salary":25000}'

a = r'{"name":"Nickname \"John\" Doe", "age":31, "Salary":25000}'

这是需要转义的 \ 以生成有效的 json：
#soJsonEscapeQuotesimport jsona = '{ "name":"Nickname \\"John\\" Doe", "age":31, "Salary":25000}'print ("initial strings given - \n", a)try:json_object1 = json.loads(a)print ("Is valid json? true")except ValueError as e:print ("Is valid json? false")
输出：
initial strings given -{ "name":"Nickname \"John\" Doe", "age":31, "Salary":25000}Is valid json? true
英文:
Its the \ that need escaping to make valid json:
#soJsonEscapeQuotesimport jsona = '{"name":"Nickname \\"John\\" Doe", "age":31, "Salary":25000}'print ("initial strings given - \n", a)try:json_object1 = json.loads(a)print ("Is valid json? true")except ValueError as e:print ("Is valid json? false")
Output:
initial strings given -{"name":"Nickname \"John\" Doe", "age":31, "Salary":25000}Is valid json? true
