erlang - problems with converting to json -

-

i'm trying convert json via jiffy , exception, seem correct

{"purchaseorder",  [{"purchaseordernumber","99503"},   {"orderdate","1999-10-20"},   {"address",    [[{"type","shipping"},      {"name",[{<<"#text">>,"ellen adams"}]},      {"street",[{<<"#text">>,"123 maple street"}]},      {"city",[{<<"#text">>,"mill valley"}]},      {"state",[{<<"#text">>,"ca"}]},      {"zip",[{<<"#text">>,"10999"}]},      {"country",[{<<"#text">>,"usa"}]}],     [{"type","billing"},      {"name",[{<<"#text">>,"tai yee"}]},      {"street",[{<<"#text">>,"8 oak avenue"}]},      {"city",[{<<"#text">>,"old town"}]},      {"state",[{<<"#text">>,"pa"}]},      {"zip",[{<<"#text">>,"95819"}]},      {"country",[{<<"#text">>,"usa"}]}]]},   {"deliverynotes",    [{<<"#text">>,"please leave packages in shed driveway."}]},   {"items",    [{"item",      [[{"partnumber","872-aa"},        {"productname",[{<<"#text">>,"lawnmower"}]},        {"quantity",[{<<"#text">>,"1"}]},        {"usprice",[{<<"#text">>,"148.95"}]},        {"comment",[{<<"#text">>,"confirm electric"}]}],       [{"partnumber","926-aa"},        {"productname",[{<<"#text">>,"baby monitor"}]},        {"quantity",[{<<"#text">>,"2"}]},        {"usprice",[{<<"#text">>,"39.98"}]},        {"shipdate",[{<<"#text">>,"1999-05-21"}]}]]}]}]}

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

help please, what's wrong?

  1. put proplists/objects in tuple

instead of [{a,b}] should {[{a,b}]}

  1. use binary strings instead of lists

instead of "string" should <<"string">>

  1. rtfm on jiffy data format: https://github.com/davisp/jiffy#data-format

example:

   {[{<<"purchaseorder">>,      {[{<<"purchaseordernumber">>,<<"99503">>},       {<<"orderdate">>,<<"1999-10-20">>},       {<<"address">>,        [{[{<<"type">>,<<"shipping">>},          {<<"name">>,{[{<<"#text">>,<<"ellen adams">>}]}},          {<<"street">>,{[{<<"#text">>,<<"123 maple street">>}]}},          {<<"city">>,{[{<<"#text">>,<<"mill valley">>}]}},          {<<"state">>,{[{<<"#text">>,<<"ca">>}]}},          {<<"zip">>,{[{<<"#text">>,<<"10999">>}]}},          {<<"country">>,{[{<<"#text">>,<<"usa">>}]}}]},         {[{<<"type">>,<<"billing">>},          {<<"name">>,{[{<<"#text">>,<<"tai yee">>}]}},          {<<"street">>,{[{<<"#text">>,<<"8 oak avenue">>}]}},          {<<"city">>,{[{<<"#text">>,<<"old town">>}]}},          {<<"state">>,{[{<<"#text">>,<<"pa">>}]}},          {<<"zip">>,{[{<<"#text">>,<<"95819">>}]}},          {<<"country">>,{[{<<"#text">>,<<"usa">>}]}}]}]},       {<<"deliverynotes">>,        {[{<<"#text">>,<<"please leave packages in shed driveway.">>}]}},       {<<"items">>,        {[{<<"item">>,          [{[{<<"partnumber">>,<<"872-aa">>},            {<<"productname">>,{[{<<"#text">>,<<"lawnmower">>}]}},            {<<"quantity">>,{[{<<"#text">>,<<"1">>}]}},            {<<"usprice">>,{[{<<"#text">>,<<"148.95">>}]}},            {<<"comment">>,{[{<<"#text">>,<<"confirm electric">>}]}}]},           {[{<<"partnumber">>,<<"926-aa">>},            {<<"productname">>,{[{<<"#text">>,<<"baby monitor">>}]}},            {<<"quantity">>,{[{<<"#text">>,<<"2">>}]}},            {<<"usprice">>,{[{<<"#text">>,<<"39.98">>}]}},            {<<"shipdate">>,{[{<<"#text">>,<<"1999-05-21">>}]}}]}]}]}}]}}]}
