Question

我的目标只是：

网址类似于：/ add？a = 1＆amp; b = 2

我的函数应该获取这些参数的值并简单地添加。但是，我实际上仍然坚持如何实现这一目标。以下是我添加功能的全部内容：

def add():
    a = 0
    b = 1
    c = a + b
    return json.dumps({'c':c})

所以如果/ add？a = 1＆amp; b = 2，它应该返回：

{"c": 3}

不

{"c": 1}

Answer 1

~~你没有清楚地描述这个问题：~~

~~是否只需要一个解析函数从url字符串中提取参数并进行数学运算;~~

或者想要对此网址发出请求并将结果作为回复。

正如你在评论中提到的web2py，它应该是第二个。我没有web2py经验，但我认为它可能与烧瓶相似。

以Flask为例。您需要为map<pair<char, char>, double>添加处理程序。我会忽略导入。

/add
