MicrosoftConsidering we have both `Analyze Document` and `Get Analyze Result` configured as operations in the document intelligence API, isn't it easier just to replace the `cognitiveservices.azure.com` URL with your `azure-api.net` URL in the outbound policy of your POST? Like this:
var apimUrl = originalOpLoc.Replace("<your cognitive services host>", "<your APIM host>");This eliminates the requirement to change the poller API.
Thank you for this suggestion! This is the way I chose to go, and it works better than the code suggested in the article. I ended up with a 404 resource not found when doing it with send-request.
In the end, this is the operation policy on my DocumentIntelligence AnalyzeDocumentFromStream:
<!--
- Policies are applied in the order they appear.
- Position <base/> inside a section to inherit policies from the outer scope.
- Comments within policies are not preserved.
-->
<!-- Add policies as children to the <inbound>, <outbound>, <backend>, and <on-error> elements -->
<policies>
<!-- Throttle, authorize, validate, cache, or transform the requests -->
<inbound>
<base />
</inbound>
<!-- Control if and how the requests are forwarded to services -->
<backend>
<base />
</backend>
<!-- Customize the responses -->
<outbound>
<base />
<set-header name="operation-location" exists-action="override">
<value>@{
// Original operation-location from backend
var originalOpLoc = context.Response.Headers.GetValueOrDefault("operation-location", "");
// Encode original URL to pass as query parameter
var encoded = System.Net.WebUtility.UrlEncode(originalOpLoc);
// Construct APIM URL pointing to poller endpoint with backendUrl
var apimUrl = originalOpLoc.Replace("document intelligence hostname", "apim hostname");
return apimUrl;
}</value>
</set-header>
</outbound>
<!-- Handle exceptions and customize error responses -->
<on-error>
<base />
</on-error>
</policies>Works like a charm now 🙂
