[gRPC #12.2] Upload file in chunks with client-streaming gRPC - Java

[@MrSpadejac]

@TECHSCHOOLGURU , Any reasons against ImageMetadata simply being a record: public record ImageMetadata(String laptopID, String type, String path) {} ?

How do I develop a grpc service in golang with the following capabilities. ● An endpoint to fetch user details based on user id. ● An endpoint to fetch a list of user details based on a list of ids. User model: { "id": 1, "fname":" Steve", "city": "LA" }

Can we achieve this in PHP 5.1 sir ? I am working on it for PHP to upload large file without set more value in php.ini. Would you please guide us if can do that in PHP. Thanks in advance.

Hi Bachtiar. Yes you can do the same thing in PHP. Just follow this guide: grpc.io/docs/tutorials/basic/php/ to implement client-streaming RPC. The idea is similar to what we've done here with Java.

How do you restrict thr server form accepting any other file types other than jpg or png? What if I am sending an exe file or a video file?

[@TECHSCHOOLGURU]

Hi Zia, You can detect the MIME file type by using the built-in method of HTTP package: pkg.go.dev/net/http#DetectContentType or this mimetype package github.com/gabriel-vasile/mimetype

@@TECHSCHOOLGURU where do I write the code that detects that for a Java spring boot maven project ?

[@TECHSCHOOLGURU]

Ah you can google Java detect MIME type, I got this result, for example: www.baeldung.com/java-file-mime-type
