[FIXED] How to generate signature based on payload with both Chinese and English in it python

Issue

I try to generate the signature (sign) by python code below with several times of edition but always get the wrong sign, would be really appreciate if someone could help with this:

import hashlib
import json

import requests

nick = ['奇思种子']
key = 'd0da37aaab474d0195cf649c889f8d34'
param = {"method":"gy.erp.shop.get","appkey":"114888","sessionkey":"3fa8000e6e844a5d865c27d4e7e1175c","page_size":"100"}
# param['nick'] = str(nick[0].encode('utf-8')) 
param['nick'] = str(nick[0]) 
pjson = json.dumps(param)


postdata = {'param': pjson }

str1 = key + pjson + key 
str2 = str1.replace(": ", ":") 
str3 = str2.replace(", ", ",") 

md = hashlib.md5()
md.update(str3.encode())
sign = md.hexdigest().upper()
param["sign"] = sign

pjson2 = json.dumps(param)
str_2 = pjson2.replace(": ", ":") 
str_3 = str_2.replace(", ", ",") 

Solution

You have to set ensure_ascii attribute to False.

import hashlib
import json

import requests

nick = ['奇思种子']
key = 'd0da37aaab474d0195cf649c889f8d34'
param = {"method":"gy.erp.shop.get","appkey":"114888","sessionkey":"3fa8000e6e844a5d865c27d4e7e1175c","page_size":"100"}
# param['nick'] = str(nick[0].encode('utf-8')) 
param['nick'] = str(nick[0]) 
pjson = json.dumps(param, ensure_ascii=False)


postdata = {'param': pjson }

str1 = key + pjson + key 
str2 = str1.replace(": ", ":") 
str3 = str2.replace(", ", ",") 

md = hashlib.md5()
md.update(str3.encode('utf-8'))
sign = md.hexdigest().upper()
param["sign"] = sign

pjson2 = json.dumps(param)
str_2 = pjson2.replace(": ", ":") 
str_3 = str_2.replace(", ", ",")
