fetch calls behavior depending on deployment model

[Anonymous]

Hi

How would a javascript fetch call executed by the custom visual behave, depending on:

• Being executed from Power BI Desktop to a publicly available URL (I assume this works no problem)
• Being executed from Power BI Desktop to a locally available URL (I assume this works no problem with the URL corresponding to an appropriate local network address)
• Being executed from Power BI Web to a publicly available URL (I assume this works no problem)
• Being executed from Power BI Web to a locally available URL (would it work since Power BI Web is running in a browser in the local network?)

Thanks

(Also, please let me know if I missed any deployment model possibility)

Hi @Anonymous ,

HTTP fetch requests work fine from inside the developer visual as long as your remote endpoint can accept requests from any domain. This is because the developer visual runs inside a sandboxed iframe with no domain of its own. Further reading: iframe reference, under the sandbox attribute. The only value enabled is allow-scripts; all others are disabled from the main window to keep the visual from interacting from the main window, except through the provided APIs.

Hopefully this gives you some ideas on how to proceed.

Regards,

Daniel
