FAQs
Can I use grpcui without specifying proto files?
Yes, if the gRPC server supports server reflection, you can use grpcui to dynamically interact with the server without specifying proto files.
This allows you to explore the services available on the server directly from the grpcui web interface.
If reflection is not enabled, you will need to specify the proto files using the -proto flag.
How do I use grpcui with services that require authentication?
To use grpcui with services that require authentication, you must include the necessary authentication tokens or credentials.
This can be done by adding custom headers in the web UI before making a request.
Add a new metadata entry with the key as Authorization and the value as your token.
How do I save the session or output from grpcui for later review?
While grpcui does not directly support saving session outputs like command-line tools might, you can manually copy responses from the web interface to a file.
Alternatively, if you need to automate session captures, consider using grpcurl with file redirection or scripting to save outputs.
What should I do if I encounter a 'Failed to process proto source files' error?
Ensure you're specifying the correct import paths with the -import-path option and that all dependent proto files are accessible.
Also, verify the paths in your proto files' import statements are correct relative to the import paths you've provided.
