我正在使用 mochiweb,但我不知道如何使用它的 json 编码器来处理复杂的数据结构。mochijson 和 mochijson2 有什么区别?有什么好的例子吗?我总是收到以下错误:
46> T6={struct,[{hello,"asdf"},{from,"1"},{to,{a,"aa"}}]}.
{struct,[{hello,"asdf"},{from,"1"},{to,{a,"aa"}}]}
47> mochijson2:encode(T6).
** exception exit: {json_encode,{bad_term,{a,"aa"}}}
in function mochijson2:json_encode/2
in call from mochijson2:'-json_encode_proplist/2-fun-0-'/3
in call from lists:foldl/3
in call from mochijson2:json_encode_proplist/2
39> T3={struct,[{hello,"asdf"},{[{from,"1"},{to,"2"}]}]}.
{struct,[{hello,"asdf"},{[{from,"1"},{to,"2"}]}]}
40> mochijson:encode(T3).
** exception error: no function clause matching mochijson:'-json_encode_proplist/2-fun-0-'({[{from,"1"},{to,"2"}]},
