In our Angular front end, we would like to provide a link that returns a PDF file. We are currently returning a RemoteStreamContent:
return new RemoteStreamContent(stream, "Report.pdf", MimeTypes.Application.Pdf);
This always returns a response with the Content-Disposition header set to "attachment", causing the browser to download the file rather than view it inline in the current browser tab.
What is the recommended way of returning a file response like this with the Content-Disposition set to "inline"?
Some options considered:
- Implementing a middleware that sets/updates the Content-Disposition header for certain API calls
- Implementing our own custom controller
Neither of these options seem ideal, as it would be preferable to have this logic encapsulated in the application service method that returns the response.

Hi,
What is the recommended way of returning a file response like this with the Content-Disposition set to "inline"?
You can create a custom controller as you said (override the default appservice to httpapi controller) and set the response header, for example:
public class MyAppServiceController : AbpControllerBase, IMyAppService { [HttpGet("data/{reportId}")] public virtual async Task<IRemoteStreamContent> GetReportAsync(Guid reportId) { Response.Headers.Add("Content-Disposition", "inline"); return new RemoteStreamContent(stream, "Report.pdf", MimeTypes.Application.Pdf); } }You just need to add a line like above (
Response.Headers.Add("Content-Disposition", "inline");). You can create your controllers in the httpapi project. This is a common practise that we also follow and use some of our modules.Regards.

Sounds good.
It would be a nice enhancement if there was a ContentDisposition property on RemoteStreamContent to allow this to be done in the application service.
Thanks!
