-
responseTimeout
Description copied from interface:RequestOptionsSetters
Schedules the response timeout that is triggered when theResponse
is not fully received within the specifiedDuration
since theResponse
started orRequest
was fully sent.Duration.ZERO
disables the limit.- Specified by:
responseTimeout
in interfaceRequestOptionsSetters
-
responseTimeoutMillis
Description copied from interface:RequestOptionsSetters
Schedules the response timeout that is triggered when theResponse
is not fully received within the specifiedresponseTimeoutMillis
since theResponse
started orRequest
was fully sent.0
disables the limit.- Specified by:
responseTimeoutMillis
in interfaceRequestOptionsSetters
-
writeTimeout

succeeds.Duration.ZERO
disables the limit.- Specified by:

Sets the maximum allowed length of a server response in bytes.0
disables the limit.- Specified by:
maxResponseLength
in interfaceRequestOptionsSetters
-
requestAutoAbortDelay
Description copied from interface:RequestOptionsSetters
Sets the amount of time to wait before aborting anHttpRequest
when its correspondingHttpResponse
is complete. This may be useful when you want to send additional data even after the response is complete. SpecifyDuration.ZERO
to abort theHttpRequest
immediately. Any negative value will not abort the request automatically. There is no delay by default.- Specified by:
requestAutoAbortDelay
in interfaceRequestOptionsSetters
-
requestAutoAbortDelayMillis
Description copied from interface:RequestOptionsSetters
Sets the amount of time in millis to wait before aborting anHttpRequest
when its correspondingHttpResponse
is complete. This may be useful when you want to send additional data even after the response is complete. Specify0
to abort theHttpRequest
immediately. Any negative value will not abort the request automatically. There is no delay by default.- Specified by:
requestAutoAbortDelayMillis
in interfaceRequestOptionsSetters
-
attr
Description copied from interface:RequestOptionsSetters
Associates the specified value with the givenAttributeKey
in this request. If this context previously contained a mapping for theAttributeKey
, the old value is replaced by the specified value.- Specified by:
attr
in interfaceRequestOptionsSetters
-
exchangeType
Description copied from interface:RequestOptionsSetters
Sets theExchangeType
that determines whether to stream anHttpRequest
orHttpResponse
. Note that anHttpRequest
will be aggregated before being written ifExchangeType.UNARY
orExchangeType.RESPONSE_STREAMING
is set. If unspecified, theClient
s try to infer a properExchangeType
depending on the content type of a request and a response. Here are examples:WebClient client = WebClient.of("https://armeria.dev"); try (ClientRequestContextCaptor captor = Clients.newContextCaptor()) { client.prepare() .post("/api/v1/items") .contentJson(new Item(...)) // A non-streaming request type. .asString() // A non-streaming response type. .execute(); assert captor.get().exchangeType() == ExchangeType.UNARY; } try (ClientRequestContextCaptor captor = Clients.newContextCaptor()) { client.get("/api/v1/items") // A non-streaming request type. .aggregate(); // A return type is not specified; Assuming that response streaming // is enabled. assert captor.get().exchangeType() == ExchangeType.RESPONSE_STREAMING; } try (ClientRequestContextCaptor captor = Clients.newContextCaptor()) { client.prepare() .post("/api/v1/items") .content(MediaType.JSON_LINES, StreamMessage.of(...)) // A streaming request type. .asFile(Path.get("/path/to/destination")) // A streaming response type. .execute(); assert captor.get().exchangeType() == ExchangeType.BIDI_STREAMING; }
Since a request and a response of
BlockingWebClient
are fully aggregated,ExchangeType.UNARY
is only supported.try (ClientRequestContextCaptor captor = Clients.newContextCaptor()) { AggregatedHttpResponse response = client.blocking().get("/api/v1/items"); assert captor.get().exchangeType() == ExchangeType.UNARY; }
gRPC clients
An
ExchangeType
is automatically inferred from theio.grpc.MethodDescriptor.MethodType
.try (ClientRequestContextCaptor captor = Clients.newContextCaptor()) { Response response = grpcClient.unaryCall(...); assert captor.get().exchangeType() == ExchangeType.UNARY; }
Thrift clients
Thrift protocols do not support streaming.
ExchangeType.UNARY
is only supported.- Specified by:
