订餐系统之同步美团商家订单

背景

　　之前写过一篇关于同步饿了么订单的文章《订餐系统之同步饿了么商家订单》，有不少人加我咨询，感觉有这方面需求的人还是满多的，毕竟现在2家几乎瓜分了市场，再做平台已然机会渺茫了，但是商户毕竟需要服务，订单还得配送出去。然后饿了

么，美团外卖都提供了面向供应商的api的权限的申请，这对我们做配送系统的说，真是一大利好。以前都是让商户手动录入其他平台的订单，费力还容易出错。还得在多个app之间来回切换，商户也是抱怨满天。有了这些接口，商户可以选择自动接单，

自动同步订单，再也不用几个app来回切换了。饿了么同步订单，在上面的文章中已经介绍了，虽然接口现在变成2.0了。有了一些变化，总的来说还是 万变不离其宗。本篇就来详细接受下同步美团订单的相关步奏。写得不对地方，欢迎指正 :）

　　具体流程，下图中写得比较详细。

上线

　　其他还有很多接口可以按需对接，比如商口数据，评论数据。目前我们用不上，暂未对接。最后一步就上线操作了。

　　未上线之前，最多能接5个商家，上线后就没有限制了。

　　目前上线要先写一个《上线申请》，然后在开放平台，里点击上线，会有美团人员联系你，确认相关信息就OK了。

　　

　　最后效果图如下：

　　

结语

　　对接美团外卖，除了提交审核时间不好，导致审核时间长了些外，其他还是蛮顺利的，他们也蛮配合的，根据接口文档几乎可以完整大部分操作。

　　就代码上而言，确定没有太多可以说的，对接过程还是有些曲折的。希望这个文章能给那个正在对接的，想对接的人提供一些帮助，如果真有帮助了，有个赞最好了。
