后台返回json结果的逻辑是 Map<String, Object> resultMap = new HashMap<>(); resultMap.put("userType", userType); resultMap.put("phone", phone); resultMap.put("channel", channel); JSONObject obj = new JSONObject(); obj.put("code", "2000"); obj.put("message", "成功"); obj.put("result", resultMap); return obj.toJSONString(); 前台得到:{"code":"2000","message":"成功","result":{"phone":"15365166305","channel":"null","userType":"高级版用户"}}可是在ajax里出现解析错误,怎么办? success: function(data){ if(data.code == '2000'){ userType = data.result.userType; } }, error: function(request, textStatus, errorThrown){ console.log(request.status); console.log(request.readyState); } errorThrown说是:Unexpected token < in JSON at position 0"
