This release commits to a stable 2.0 API. Read the 2.0.0-RC1 changes for advice on upgrading from 1.x to 2.x.
2014-06-21
- API Change: Use
IOException
inCallback.onFailure()
. This is a source-incompatible change, and is different from OkHttp 2.0.0-RC2 which usedThrowable
. - Fix: Fixed a caching bug where we weren't storing rewritten request headers
like
Accept-Encoding
. - Fix: Fixed bugs in handling the SPDY window size. This was stalling certain large downloads
- Update the language level to Java 7. (OkHttp requires Android 2.3+ or Java 7+.)

This update fixes problems in 2.0.0-RC1. Read the 2.0.0-RC1 changes for advice on upgrading from 1.x to 2.x.
-
Fix: Don't leak connections! There was a regression in 2.0.0-RC1 where connections were neither closed nor pooled.
-
Fix: Revert builder-style return types from OkHttpClient's timeout methods for binary compatibility with OkHttp 1.x.
-
Fix: Don't skip client stream 1 on SPDY/3.1. This fixes SPDY connectivity to
https://google.com
, which doesn't follow the SPDY/3.1 spec! -
Fix: Always configure NPN headers. This fixes connectivity to
https://facebook.com
when SPDY and HTTP/2 are both disabled. Otherwise an unexpected NPN response is received and OkHttp crashes. -
Fix: Write continuation frames when HPACK data is larger than 16383 bytes.
-
Fix: Don't drop uncaught exceptions thrown in async calls.
-
Fix: Throw an exception eagerly when a request body is not legal. Previously we ignored the problem at request-building time, only to crash later with a
NullPointerException
. -
Fix: Include a backwards-compatible
OkHttp-Response-Source
header withOkUrlFactory
responses. -
Fix: Don't include a default User-Agent header in requests made with the Call API. Requests made with OkUrlFactory will continue to have a default user agent.
-
New: Guava-like API to create headers:
Headers headers = Headers.of(name1, value1, name2, value2, ...).
-
New: Make the content-type header optional for request bodies.
-
New:
Response.isSuccessful()
is a convenient API to check response codes. -
New: The response body can now be read outside of the callback. Response bodies must always be closed, otherwise they will leak connections!
-
New: APIs to create multipart request bodies (
MultipartBuilder
) and form encoding bodies (FormEncodingBuilder
).

OkHttp 2 is designed around a new API that is true to HTTP, with classes for requests, responses, headers, and calls. It uses modern Java patterns like immutability and chained builders. The API now offers asynchronous callbacks in addition to synchronous blocking calls.
-
New Request and Response types, each with their own builder. There's also a
RequestBody
class to write the request body to the network and aResponseBody
to read the response body from the network. The standaloneHeaders
class offers full access to the HTTP headers. -
Okio dependency added. OkHttp now depends on Okio, an I/O library that makes it easier to access, store and process data. Using this library internally makes OkHttp faster while consuming less memory. You can write a
RequestBody
as an OkioBufferedSink
and aResponseBody
as an OkioBufferedSource
. StandardInputStream
andOutputStream
access is also available. -
New Call and Callback types execute requests and receive their responses. Both types of calls can be canceled via the
Call
or theOkHttpClient
. -
URLConnection support has moved to the okhttp-urlconnection module. If you're upgrading from 1.x, this change will impact you. You will need to add the
okhttp-urlconnection
module to your project and use theOkUrlFactory
to create new instances ofHttpURLConnection
:// OkHttp 1.x: HttpURLConnection connection = client.open(url); // OkHttp 2.x: HttpURLConnection connection = new OkUrlFactory(client).open(url);
-
Custom caches are no longer supported. In OkHttp 1.x it was possible to define your own response cache with the
java.net.ResponseCache
and OkHttp'sOkResponseCache
interfaces. Both of these APIs have been dropped. In OkHttp 2 the built-in disk cache is the only supported response cache. -
HttpResponseCache has been renamed to Cache. Install it with
OkHttpClient.setCache(...)
instead ofOkHttpClient.setResponseCache(...)
. -
OkAuthenticator has been replaced with Authenticator. This new authenticator has access to the full incoming response and can respond with whichever followup request is appropriate. The
Challenge
class is now a top-level class andCredential
is replaced with a utility class calledCredentials
. -
OkHttpClient.getFollowProtocolRedirects() renamed to getFollowSslRedirects(). We reserve the word protocol for the HTTP version being used (HTTP/1.1, HTTP/2). The old name of this method was misleading; it was always used to configure redirects between
https://
andhttp://
schemes. -
RouteDatabase is no longer public API. OkHttp continues to track which routes have failed but this is no exposed in the API.
-
ResponseSource is gone. This enum exposed whether a response came from the cache, network, or both. OkHttp 2 offers more detail with raw access to the cache and network responses in the new
Response
class. -
TunnelRequest is gone. It specified how to connect to an HTTP proxy. OkHttp 2 uses the new
Request
class for this. -
Dispatcher is a new class to manages the queue of asynchronous calls. It implements limits on total in-flight calls and in-flight calls per host.
- Support Android
TrafficStats
socket tagging. - Drop authentication headers on redirect.
- Added support for compressed data frames.
- Process push promise callbacks in order.
- Update to http/2 draft 12.
- Update to HPACK draft 07.
- Add ALPN support. Maven will use ALPN on OpenJDK 8.
- Update NPN dependency to target
jdk7u60-b13
andOracle jdk7u55-b13
. - Ensure SPDY variants support zero-length DELETE and POST.
- Prevent leaking a cache item's InputStreams when metadata read fails.
- Use a string to identify TLS versions in routes.
- Add frame logger for HTTP/2.
- Replacing
httpMinorVersion
withProtocol
. Expose HTTP/1.0 as a potential protocol. - Use
Protocol
to describe framing. - Implement write timeouts for HTTP/1.1 streams.
- Avoid use of SPDY stream ID 1, as that's typically used for UPGRADE.
- Support OAuth in
Authenticator
. - Permit a dangling semicolon in media type parsing.
2014-05-23
- Offer bridges to make it easier to migrate from OkHttp 1.x to OkHttp 2.0.
This adds
OkUrlFactory
,Cache
, and@Deprecated
annotations for APIs dropped in 2.0.
2014-04-14
- Drop ALPN support in Android. There's a concurrency bug in all currently-shipping versions.
- Support asynchronous disconnects by breaking the socket only. This should prevent flakiness from multiple threads concurrently accessing a stream.
2014-03-29
- Fix bug where the Content-Length header was not always dropped when following a redirect from a POST to a GET.
- Implement basic support for
Thread.interrupt()
. OkHttp now checks for an interruption before doing a blocking call. If it is interrupted, it throws anInterruptedIOException
.
2014-03-17
- Fix bug where deleting a file that was absent from the
HttpResponseCache
caused an IOException. - Fix bug in HTTP/2 where our HPACK decoder wasn't emitting entries in certain eviction scenarios, leading to dropped response headers.
2014-03-11
- Fix 1.5.0 regression where connections should not have been recycled.
- Fix 1.5.0 regression where transparent Gzip was broken by attempting to recover from another I/O failure.
- Fix problems where spdy/3.1 headers may not have been compressed properly.
- Fix problems with spdy/3.1 and http/2 where the wrong window size was being used.
- Fix 1.5.0 regression where conditional cache responses could corrupt the connection pool.

Applications that want to use the global SSL context with OkHttp should configure their OkHttpClient instances with the following:
okHttpClient.setSslSocketFactory(HttpsURLConnection.getDefaultSSLSocketFactory());
A simpler solution is to avoid the shared default SSL socket factory. Instead, if you need to customize SSL, do so for your specific OkHttpClient instance only.
Previously OkHttp added a synthetic response header, OkHttp-Selected-Transport
. It
has been replaced with a new synthetic header, OkHttp-Selected-Protocol
.
