外賣(mài)行業(yè)近幾年發(fā)展迅猛婉徘，微信平臺(tái)也成為其中的一個(gè)主力軍捌议，小程序的橫空出世，讓不少微信外賣(mài)平臺(tái)加入其中嚼黔，紛紛開(kāi)發(fā)了自己的餐廳點(diǎn)餐小程序
餐廳點(diǎn)餐小程序功能非常方便细层，對(duì)于用戶(hù)來(lái)講，操作如下：
1.打開(kāi)自己的微信賬號(hào)唬涧，選擇【小程序】
2.點(diǎn)擊【小程序】進(jìn)入疫赎，進(jìn)入餐廳點(diǎn)餐小程序系統(tǒng)
3.選擇這家餐廳之后，進(jìn)入微信授權(quán)界面碎节，選擇允許
4.進(jìn)入店內(nèi)之后捧搞，選擇外賣(mài)字樣，可以看到這家店的詳細(xì)地址和詳細(xì)聯(lián)系電話以及營(yíng)業(yè)時(shí)間，還有商家的環(huán)境
5.選擇外賣(mài)的界面之后胎撇，在左邊有一個(gè)列表是大分類(lèi)：如熱銷(xiāo)介粘、優(yōu)惠、套餐晚树、主食姻采、配菜、飲料等等
6.點(diǎn)擊選擇規(guī)格之后進(jìn)入選項(xiàng)中口味的選擇：選擇好之后【加入購(gòu)物車(chē)】
7.選擇【加入購(gòu)物車(chē)】爵憎，如何沒(méi)有其他需要點(diǎn)餐的就可以直接點(diǎn)擊【選好了】慨亲，還需要選擇其他外賣(mài)的話都一致加入購(gòu)物車(chē)
8.最后在想【選好了】點(diǎn)擊進(jìn)入【訂單提交】，添加好收貨地址之后宝鼓、收貨人刑棵、聯(lián)系電話進(jìn)去付款即可∮拚。可選擇填寫(xiě)備注蛉签，比如口味、偏好等
微信小程序餐廳點(diǎn)餐界面截圖茂附，所有數(shù)據(jù)都是通過(guò)后臺(tái)設(shè)置上傳正蛙。
