How can I send file to list - .net core web api - postman

Question

I'm trying to send a file from a postman to a web api, method on web api is expecting a list of type which contains doc type, file and folder name.. posted below:

Web api method:

[HttpPost("post-images")]
public async Task<IList<RepositoryItem>> PostAnImages (IList<PostRepoRequest> request)
{
    // rest of the code 
}

PostRepoRequest class:

public class PostRepoRequest
{
    public FileType FileType { get; set; }
    public IFormFile File { get; set; }
    public string Folder { get; set; }
}

As it's possible to notice I've never received a file, its allways null, I've tried also setting a header content-type as multipart/form-data but that didn't worked aswell..

What might be the trick here?

Thanks

Cheers

You need to change the request body with dot pattern like this:

Then you need to add [FromForm] attribute to the controller input parameter. Also note that the variable names in the postman and controller must match.

[HttpPost("post-images")]
public async Task<IList<RepositoryItem>> PostAnImages ([FromForm]IList<PostRepoRequest> repositoryItems)

With these changes, you will be able to get the request correctly:
