在做项目时候需要将json对象转化为String字符串,很自然的可以想到使用toJSONString方法,那么这里问题就来了,在使用该方法的时候发现了一个问题,当接收到的报文有null值时,在转化为json字符串时为null的字段会被自动过滤掉,查询资料字后发现可以使用一些序列化的参数来处理这种情况 二、处理 JSONObject.toJSONString(re...

#checkdatatypewithtype()method print(type(employee_string))#convert string to object json_object = json.loads(employee_string)#check newdatatypeprint(type(json_object)) 上面的代码就可以直接让 Python 把字符串转换为 JSON 的对象了。 当我们完成转换后,就可以对 JSON 的对象进行相关操作了。

You can also get a string representation of a JSON value (serialize): // explicit conversion to string std::string s = j.dump(); // {"happy":true,"pi":3.141} // serialization with pretty printing // pass in the amount of spaces to indent std::cout << j.dump(4) << std::endl...
