Important: This documentation is about an older version. It's relevant only to the release noted, many of the features and functions have been updated or replaced. Please view the current version.
Define constants to distinguish between gRPC Response statuses.
Constant
Description
StatusOK
OK is returned on success.
StatusCanceled
Canceled indicates the operation was canceled (typically by the caller).
StatusUnknown
Unknown error.
StatusInvalidArgument
InvalidArgument indicates the client specified an invalid argument.
StatusDeadlineExceeded
DeadlineExceeded means operation expired before completion.
StatusNotFound
NotFound means some requested entity (e.g., file or directory) was not found.
StatusAlreadyExists
AlreadyExists means an attempt to create an entity failed because one already exists.
StatusPermissionDenied
PermissionDenied indicates the caller does not have permission to execute the specified operation.
StatusResourceExhausted
ResourceExhausted indicates some resource has been exhausted, perhaps a per-user quota, or perhaps the entire file system is out of space.
StatusFailedPrecondition
FailedPrecondition indicates operation was rejected because the system is not in a state required for the operation’s execution.
StatusAborted
Aborted indicates the operation was aborted, typically due to a concurrency issue like sequencer check failures, transaction aborts, etc.
StatusOutOfRange
OutOfRange means operation was attempted past the valid range. E.g., seeking or reading past end of file.
StatusUnimplemented
Unimplemented indicates operation is not implemented or not supported/enabled in this service.
StatusInternal
Internal errors. Means some invariants expected by the underlying system have been broken.
StatusUnavailable
Unavailable indicates the service is currently unavailable. This is a most likely a transient condition and may be corrected by retrying with a backoff. Note that it is not always safe to retry non-idempotent operations.
StatusDataLoss
DataLoss indicates unrecoverable data loss or corruption.
StatusUnauthenticated
Unauthenticated indicates the request does not have valid authentication credentials for the operation.
Example
JavaScript
import grpc from'k6/net/grpc';import{ check, sleep }from'k6';const client =newgrpc.Client();
client.load(['definitions'],'hello.proto');exportdefault()=>{
client.connect('grpcbin.test.k6.io:9001',{// plaintext: false});const data ={greeting:'Bert'};const response = client.invoke('hello.HelloService/SayHello', data);check(response,{'status is OK':(r)=> r && r.status === grpc.StatusOK,});
client.close();sleep(1);};
