服務(wù)端返回json數(shù)據(jù)

需求背景

1.Android項目多為Java寫的，經(jīng)常會因?yàn)閿?shù)據(jù)null出現(xiàn)空指針，代碼中如果每個數(shù)據(jù)都判斷，顯得冗余。
2.前端的控件總是用多個條件判斷是否顯示。如果漏掉一個條件就會出現(xiàn)問題。發(fā)版后，產(chǎn)品如果需要改變判斷條件，客戶端就要重新發(fā)版。
3.有些時候后臺給的數(shù)據(jù)并不是前端要的，溝通不足。前端使用起來會增加開發(fā)成本。

1.先看我們的數(shù)據(jù)

對話框提示

希望在以下功能點(diǎn)改進(jìn)：

1.errorCode多余。只用statusCode就可以表示狀態(tài)碼。
2.無論是列表還是簡單數(shù)據(jù)，data節(jié)點(diǎn)下都是{}。
3.不要返回null。都要有值，如0 、""、false、[]、{}。
4.數(shù)據(jù)應(yīng)該歸類，層次結(jié)構(gòu)明顯。statusDesc、status應(yīng)該歸于一個對象。showTypeDesc、showType應(yīng)該歸于一個對象。
5.枚舉值String AUDITING,前端要維護(hù)一套一樣的字符串。如果錯一個字母Android、iOS、h5都要要重新改動，不如返回int數(shù)字1、2、3。
6.判斷控件的顯示與否，應(yīng)該返回一個boolean或者int供前端判斷。多個條件控制控件顯示的應(yīng)該由后臺處理好為1個字段后返回。這樣即使以后想增減條件只要后臺改動即可。
7.對話框提示，標(biāo)題和內(nèi)容應(yīng)該由后臺返回，放在一個對象里。這樣易于維護(hù)，保證前端的文案統(tǒng)一。
8.點(diǎn)擊列表跳轉(zhuǎn)到不同頁面，應(yīng)該由后臺控制。返回對象有跳轉(zhuǎn)的頁面和參數(shù)。

1.數(shù)據(jù)沒有null，為0、""、false。前后端交互很強(qiáng)，現(xiàn)有的問題是前后端溝通不多，后臺給的并不一定是前端想要的。可以增加接口設(shè)計環(huán)節(jié)，前后端共同參與。
2.小圖標(biāo)歸類于navigate_bar。右上角客服圖標(biāo)、消息圖標(biāo)、發(fā)紅包圖標(biāo)歸于一類。點(diǎn)擊客服圖標(biāo)、消息圖標(biāo)，跳轉(zhuǎn)到對應(yīng)頁面click_url。

                    "click_url":"",
                    "icon_url":"",
                    "sub_label_list":[

                    ]
                }
            ]

4.點(diǎn)擊按鈕跳轉(zhuǎn)。點(diǎn)擊我的收藏 "click_url":"meituanwaimai://waimai.meituan.com/likedpoi"，跳轉(zhuǎn)的是美團(tuán)外賣app的likedpoi頁面。
5.多個標(biāo)簽的代碼(例如:票面標(biāo)簽)

{
  "seatPlanTags": [
    {
      "displayName": "折",
      "name": "DISCOUNT"
    },
    {
      "displayName": "搶",
      "name": "QIANG"
    }
  ]
}

參考美團(tuán)的button_list。name字段 DISCOUNT、QIANG多余，只要標(biāo)簽名稱或者int標(biāo)識。
