Erlang / Misultin / erlsom错误/进程死亡

erlang代码:

-module(index).
-compile(export_all).

-include_lib("erlsom/include/erlsom.hrl").

start(Port) ->
    misultin:start_link([{port, Port}, {loop, fun(Req) -> handle_http(Req) end}]).

stop() ->
    misultin:stop().

handle_http(Req) ->
    Var = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><request><code>1</code><var1>123456</var1><var2>qwerty</var2></request>",
    XmlErlsom = erlsom:simple_form(Var),
    Req:ok("~s", [Var]).

在我编译代码并启动服务器之后,我打开了localhost:8080 /并且shell给了我以下错误:

http process <0.196.0> has died with reason: {badarg,
                                          [{erlang,list_to_binary,
                                            [[{ok,
                                               {"request",[],
                                                [{"code",[],["1"]},
                                                 {"var1",[],["123456"]},
                                                 {"var2",[],["qwerty"]}]},
                                               []}]]},

ChicagoBoss的同一个lib'erlsom'成功运作......

之后我尝试使用xmerl,但结果类似。

答案 0 :(得分:1)

erlsom:simple_form返回{ok,ParsedData}形式的元组:

A = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><request><code>1</code><var1>123456</var1>`<var2>qwerty</var2></request>".

> erlsom:simple_form(A).
{ok,{"request",[],
     [{"code",[],["1"]},
      {"var1",[],["123456"]},
      {"var2",[],["qwerty"]}]},
    []}

我相信你试图将这个返回的元组传递给Req:ok(),它需要列表或二进制或者iodata或其他除了元组之外的其他元素。
