okhttp 3.3.0 发布了，改进记录如下： 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 theSSLSocketFactory. 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. <dependency> <groupId>com.squareup.okio</groupId> <artifactId>okio</artifactId> <version>1.8.0</version> </dependency> 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, which refuses 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. 下载地址： Source code (zip) Source code (tar.gz) okhttp 3.3.0 发布，HTTP 客户端开发包下载地址
