本文主要是介绍python3 json.dumps 中文乱码问题，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
json.dumps 使用的ascii编码。
输出中文需要指定ensure_ascii=False
test_dic = {'a': '测', 'b': 'abc'}print(test_dic)
# {'a': '测', 'b': 'abc'}print(str(test_dic))
# {'a': '测', 'b': 'abc'}
print(str(test_dic).replace('测', '测试'))
# {'a': '测试', 'b': 'abc'}
# print(json.loads(str(test_dic))) # json.loads只认双引号
