python requests post json data

I want to post JSON data by requests. I used Fiddler to inspect the data transmission. The data I want to post is below:

{'configList': [{'ccolumn': 'gender', 'ctable': 'arc_mxdata_operator', 'cvalue': '男', 'formula': '包含', 'integral': 1, 'integralIfMissing': 0, 'resultIfMissing': '10'}, {'ccolumn': 'gender', 'ctable': 'arc_mxdata_operator', 'cvalue': '女', 'formula': '包含', 'integral': 0, 'integralIfMissing': 0, 'resultIfMissing': '10'}], 'id': 'Sushifaker', 'infoList': [{'info_formula': '<=', 'info_integral': 5, 'info_result': '30'}], 'name': 'Submit2018-11-27-19-18-30', 'ratio': None, 'ratioMaxCount': None, 'type': '10', 'typeResultStatus': '10'} 

I found this data is urlencoded when uploading. So I encode the data in python

data = json.dumps(data, ensure_ascii=False) rs = requests.post(url, data=data) 

The response in rs is failed. I can not post the data. But I found the correct data found in Fiddler is

name=Submit2018-11-27-19-18-30&id=999&ratio=&ratioMaxCount=&configList=%5B%7B%22ctable%22%3A%22arc_mxdata_operator%22%2C%22ccolumn%22%3A%22gender%22%2C%22formula%22%3A%22%E5%8C%85%E5%90%AB%22%2C%22cvalue%22%3A%22%E7%94%B7%22%2C%22integral%22%3A1%2C%22integralIfMissing%22%3A0%7D%2C%7B%22ctable%22%3A%22arc_mxdata_operator%22%2C%22ccolumn%22%3A%22gender%22%2C%22formula%22%3A%22%E5%8C%85%E5%90%AB%22%2C%22cvalue%22%3A%22%E5%A5%B3%22%2C%22integral%22%3A0%2C%22integralIfMissing%22%3A0%7D%5D&infoList=%5B%7B%22info_formula%22%3A%22%3C%3D%22%2C%22info_integral%22%3A5%2C%22info_result%22%3A%2230%22%7D%5D&type=10&typeResultStatus=10&ruleType=0 

The difference between two data is ratio=&ratioMaxCount=, it's looks like a parameters in a url. I don't know why and how to get a correct data to post.

Update: After reading doc from urllib and check the difference between two output. I have misused quote and urlencode.
