OkHttp v3.3.0 發布,一個高效的Http客戶端

OkHttp是一個高效的Http客戶端，在Android開發中被大量使用，主要有如下的特點：

• 支持HTTP2/SPDY黑科技
• socket自動選擇最好路線，并支持自動重連
• 擁有自動維護的socket連接池，減少握手次數
• 擁有隊列線程池，輕松寫并發
• 擁有Interceptors輕松處理請求與響應（比如透明GZIP壓縮,LOGGING）
• 基于Headers的緩存策略

更新日志

• New: Response.sentRequestAtMillis() and receivedResponseAtMillis() methods track the system's local time when network calls are made. These replace the OkHttp-Sent-Millis and OkHttp-Sent-Millis headers that were present in earlier versions of OkHttp.
• New: Accept user-provided trust managers in OkHttpClient.Builder. This allows OkHttp to satisfy its TLS requirements directly. Otherwise OkHttp will use reflection to extract the TrustManager from the SSLSocketFactory.
• New: Support prerelease Java 9. This gets ALPN from the platform rather than relying on the alpn-boot bootclasspath override.
• New: HttpLoggingInterceptor now logs connection failures.

• New: Upgrade to Okio 1.8.0.

• Fix: Gracefully recover from a failure to rebuild the cache journal.

• Fix: Don't corrupt cache entries when a cache entry is evicted while it is being updated.
• Fix: Make logging more consistent throughout OkHttp.
• Fix: Log plaintext bodies only. This uses simple heuristics to differentiate text from other data.
• Fix: Recover from REFUSED_STREAM errors in HTTP/2. This should improve interoperability with Nginx 1.10.0, whichrefuses streams created before HTTP/2 settings have been acknowledged.
• Fix: Improve recovery from failed routes.
• Fix: Accommodate tunneling proxies that close the connection after an auth challenge.
• Fix: Use the proxy authenticator when authenticating HTTP proxies. This regression was introduced in OkHttp 3.0.
• Fix: Fail fast if network interceptors transform the response body such that closing it doesn't also close the underlying stream. We had a bug where OkHttp would attempt to reuse a connection but couldn't because it was still held by a prior request.
• Fix: Ensure network interceptors always have access to the underlying connection.
• Fix: Use X509TrustManagerExtensions on Android 17+.
• Fix: Unblock waiting dispatchers on MockWebServer shutdown.
