Forwarding and Recording gRPC Traffic
The generated mock server is capable of forwarding an incoming request to another gRPC server and store the response before returning it to the caller. The recorded responses can be obtained by the /recordings
endpoint in the REST server.
To activate forwarding you must create a stub that contains a forward
instead of the response
. Using the provided Greeter
service as an example, the stub would be created like this:
POST 127.0.0.1:1068/stubs
{
"fullMethod": "/carvalhorr.greeter.Greeter/SayHello",
"request": {
"match": "exact",
"content": {
"name": "John"
}
},
"forward": {
"serverAddress": "yourserver:port",
"record": true
}
}
You can control if the communication will be recorded through the record
field. You must provide the remote server
address in the field serverAddress
in the format HOST:PORT
.
When the mock server receives a request that matches the stub's request, it forwards the call to the external server, records the request/response (if recording is enabled), and returns the response to the original caller.
To obtain the recorded stubs, make a GET
call to the /recordings
endpoint.
- Only insecure requests are supported.
- Error responses are not recorded at this moment.
