azure - 访问状态代码或使用 发出的请求

Question

我正在使用 <send-request> 发出请求政策，我需要检查请求的状态代码。为此，我尝试访问 response-variable-name 的 StatusCode 属性。 。但是，当使用此代码时 -

context.Variables["LogFailedEvent"].StatusCode

我看到这个错误 -

Error in element 'set-body' on line 83, column 4: 'object' does not contain a definition for 'StatusCode' and no extension method 'StatusCode' accepting a first argument of type 'object' could be found

根据docs -

The response-variable-name attribute is used to give access the returned response. The name defined in this property can be used as a key into the context.Variables dictionary to access the IResponse object.

要么我误解了文档中的内容，要么文档是错误的。有人可以提出解决方案吗？

        <set-body>@(string.Format("{{\"message\":\"event captured by LogFailedEvents\",\"requestId\":\"{0}\",\"statusCode\":\"{1}\",}}", context.RequestId.ToString(), context.Variables["LogFailedEvent"].StatusCode))</set-body>

    </when>

您需要转换它:

((IResponse)context.Variables["LogFailedEvent"]).StatusCode

此外，由于您设置了ignore-error =“true”，您可能需要首先检查变量是否包含此键，因为在这种情况下，如果请求失败，则根本不会创建此变量。
