form里有一些name为一致的 value为json的字符串
如果和图片一起上传双引号会带上右斜杠，然后会出现解析不了的问题
带图片是正常的json数组

org.json.JSONException: JSONArray[0] is not a JSONObject.

["{\"type\":\"a11797a820094237bd5dec39cfc80ff9\",\"parentId\":31,\"parentNumber\":\"No-1-8\"}", "{}", "{}", "{}", "{}", "{}", "{}"]

[{"type":"a11797a820094237bd5dec39cfc80ff9","parentId":22,"parentNumber":"No-1-6"},{},{},{},{},{},{}]

这是不带图片的 楼上是带图片的

入口方法贴一下

    @At("/addDo")
    @Ok("json")

                for (int i=0;i<picList.length;i++){

                    pic.setPigeonId(pigeonBaseInfo.getId());
                    pic.setPicUrl(picList[i]);
                    pic.setSequence(i);

                }
            }

                        pigeonInheritInfo.setNumber(pigeonBaseInfo.getRingNumber());
                        //判断是否是子代添加需要特殊处理

                        pigeonInheritInfo.setParentNumber(info.getString("parentNumber"));
                        pigeonInheritInfoService.insert(pigeonInheritInfo);
                    }
                }
            }
			return Result.success("system.success");
		} catch (Exception e) {
			return Result.error("system.error");
		}
    }

relation就是作为传过来的json串

用Chrome 的控制台看看服务器返回的是什么

无法解析json

没有文件的时候, 前端用json发过来的吧, 有文件的时候, 走了mulitpart了, 目测是前端问题

要么检查一下前端的逻辑, 要么后端判断一下, 有转义的时候就加一层转换. 那种双引号带转义的json,是一个json字符串再次被转json字符串的结果.
