报错 2003 签名错误，能帮忙看看吗？达达的 immediateDelivery.addOrder
你好解决了么 我也是这个问题 不知道到底哪里出问题了
1 达达那里应该注册两个号，一个是商户号，一个是开发者账号，然后登入商户号，并绑定开发者账号，此时关联成功之后，然后在微信小程序后台新增绑定那里，添加上面的商户号，此时商户号和开发者账号都关联上了小程序，此时才能app_key和app_secret才是对应的
文档算法
delivery_sign=SHA1(shopid + shop_order_id + AppSecret)
我的算法
$delivery_sign=sha1($dada_shop_id.$shop_order_id.$dada_app_secret);
其中$dada_shop_id=达达APP_Key=dadae5e77242bf27905
$dada_app_secret=达达APP_Secret
以上两个值，从达达开放平台-我是商户入口进入并获得，且和immediateDelivery.getBindAccount接口查询结果一致
$shop_order_id=自定义订单编号
且我算出来的$delivery_sign和网上工具算出来的sha1结果相等
所以。。。想请教一下这个$delivery_sign是不是还有什么我没考虑到的坑？
签名错误指delivery_sign设置不对，请参考
