如何创建 Azure Function 应用程序 + Swagger 以供逻辑应用程序使用

Question

I have an Azure Function App in.Net Core 3.1 that implements Swagger. The Swagger page works as intended. When I try to create a Logic App that uses the HTTP + Swagger step, it asks for the Swagger Enpoint Url . So far any entries generate error:

Failed to fetch swagger with error message: Failed to fetch. Ensure you have CORS enabled on the endpoint and are calling a valid HTTPS endpoint.

I have tried the following urls:

• https://xxx.azurewebsites.net/api/swagger/ui#
• https://xxx.azurewebsites.net/api/swagger/json

I have enabled CORS in the function app, but I do not know what to use for Allowed Origins . Docs said to use '*', but that results in:

The Access-Control-Allow-Credentials response header is not compatible with wildcard origin.

Answer 1

To allow CORS as described check-box needs to be off. Now HTTP+Swagger connects and appears to function.
