Functions

Uses for declarative auth design, where the authentication/authorization decision is taken by reading the auth annotations provided in service/resource and the Authorization header of request.

Returns the deadline value as time:Utc. This can be used to get the deadline and propagate it to subsequent internal calls.

1time:Utc?|time:Error deadline = grpc:getDeadline(map<string|string[]> headerMap);

Returns the header value with the specified header name. If there are more than one header values for the specified header name, the first value is returned.

1map<string|string[]> headerMap = request.headers;
2string|grpc:Error result = grpc:getHeader(headerMap, "content-type");

Gets all the transport headers with the specified header name.

1map<string|string[]> headerMap = request.headers;
2string[]|grpc:Error result = grpc:getHeaders(headerMap, "content-type");

Checks whether the deadline is already exceeded or not.

1boolean|time:Error isCancelled = grpc:isCancelled(map<string|string[]> headerMap);

Enables the compression support by adding the grpc-encoding header to the given headers.

1map<string|string[]> headers = grpc:setCompression(grpc:GZIP);

Enables the deadline by adding the deadline header to the given headers.

1time:Utc current = time:utcNow();
2time:Utc deadline = time:utcAddSeconds(current, 300);
3map<string|string[]> headers = grpc:setDeadline(deadline);
