下单成功之后，前往达达后台查看订单信息; 发现 订单寄出地址，与参数 sender的地址不一样；发现地址是使用了达达后台门店的地址
根据 微信接口文档说明，以及之前 类似相关问题的回复，我们下单传参数，没有 传shop_no参数，但是 好像sender参数 并没有什么作用；
下单成功之后，寄出地址，并不是 sender参数的地址；
并且，其他参数相同的情况，sender地址 不一样， 运费却都一样，所以，我们怀疑，sender参数 是个摆设；
请求微信技术小哥帮忙排查一下！！！！
之前提过类似相关的问题，链接如下：
shop_no的地址和sender字段的地址，微信侧都会传给运力公司。但是，具体是用sender字段的地址还是门店的地址取决于运力，可能不同的运力对于2个字段的逻辑不一样。
就你的问题而言，达达确实是用的门店地址，但是其他运力和达达的逻辑可能会不同的。所以，我们的建议是shop_no的地址和sender字段的地址两者保持一致。
