你这数组里面数据不对，要么不要index，要么再套一层对象

[
              {
                    "citycode": "0535",
                    "adcode": "370600",
                    "name": "烟台市",
                }
]

[
      {
             "0" :{
                    "citycode": "0535",
                    "adcode": "370600",
                    "name": "烟台市",
                }
      }
]

district后面应该是[{“0”:{...}}],或者[{"citycode":...,"adcode":...},{"citycode":...,"adcode":...}],而不是“0”:{...}

把键值去了
