Question

我希望API管理服务中的我的API之一可以在CosmosDB中调用存储过程并返回其结果。似乎有关该主题的文档不多。

到目前为止我的尝试：

前端：具有三个参数的GET方法
入站处理：我对该问题的代码进行了如下修改

后端：HTTPS尾随以下URL：https：// {myCosmosName} .documents.azure.com /

但是，当我测试API时，我系统地收到以下错误消息：

输入的授权令牌无法满足请求。请检查是否根据协议构建了预期的有效负载，并检查所使用的密钥。服务器使用以下有效负载进行签名：'get \ nsprocs \ ndbs / {myDBName} / colls / {myDBName} \ ntue，2018年9月18日09:31:58 gmt \ n \ n'\ r \ nActivityId：64586521-cf37- 44e5-80a4-bac0a9d3b261，Microsoft.Azure.Documents.Common / 2.0.0.0

我在那里的问题：

如何使此调用适用于我的存储过程？
如何将API参数传递给对存储过程的调用？

Answer 1

要发送参数，请查看this。设置授权令牌似乎有些错误，请参阅this。
