Class SystemDefaultHttpClient

java.lang.Object

org.apache.http.impl.client.CloseableHttpClient

org.apache.http.impl.client.AbstractHttpClient

org.apache.http.impl.client.DefaultHttpClient

org.apache.http.impl.client.SystemDefaultHttpClient

All Implemented Interfaces:

Closeable ， AutoCloseable ， HttpClient

已过时。

（4.3）使用HttpClientBuilder

@Contract(threading=SAFE_CONDITIONAL)
@Deprecated
public class SystemDefaultHttpClient
extends DefaultHttpClient

DefaultHttpClient的扩展使用系统属性预先配置。

以下系统属性由此类考虑：

• ssl.TrustManagerFactory.algorithm
• javax.net.ssl.trustStoreType
• javax.net.ssl.trustStore中
• javax.net.ssl.trustStoreProvider
• javax.net.ssl.trustStorePassword中
• java.home
• ssl.KeyManagerFactory.algorithm
• javax.net.ssl.keyStoreType
• javax.net.ssl.keyStore
• javax.net.ssl.keyStoreProvider
• javax.net.ssl.keyStorePassword
• http.proxyHost
• 把http.proxyPort
• http.nonProxyHosts
• http.keepAlive
• http.maxConnections

以下参数可用于自定义此类的行为：

• CoreProtocolPNames.PROTOCOL_VERSION
• CoreProtocolPNames.STRICT_TRANSFER_ENCODING
• CoreProtocolPNames.HTTP_ELEMENT_CHARSET
• CoreProtocolPNames.USE_EXPECT_CONTINUE
• CoreProtocolPNames.WAIT_FOR_CONTINUE
• CoreProtocolPNames.USER_AGENT
• CoreConnectionPNames.TCP_NODELAY
• CoreConnectionPNames.SO_TIMEOUT
• CoreConnectionPNames.SO_LINGER
• CoreConnectionPNames.SO_REUSEADDR
• CoreConnectionPNames.SOCKET_BUFFER_SIZE
• CoreConnectionPNames.CONNECTION_TIMEOUT
• CoreConnectionPNames.MAX_LINE_LENGTH
• CoreConnectionPNames.MAX_HEADER_COUNT
• CoreConnectionPNames.STALE_CONNECTION_CHECK
• ConnRoutePNames.FORCED_ROUTE
• ConnRoutePNames.LOCAL_ADDRESS
• ConnRoutePNames.DEFAULT_PROXY
• CookieSpecPNames.DATE_PATTERNS
• CookieSpecPNames.SINGLE_COOKIE_HEADER
• AuthPNames.CREDENTIAL_CHARSET
• ClientPNames.COOKIE_POLICY
• ClientPNames.HANDLE_AUTHENTICATION
• ClientPNames.HANDLE_REDIRECTS
• ClientPNames.MAX_REDIRECTS
• ClientPNames.ALLOW_CIRCULAR_REDIRECTS
• ClientPNames.VIRTUAL_HOST
• ClientPNames.DEFAULT_HOST
• ClientPNames.DEFAULT_HEADERS
• ClientPNames.CONN_MANAGER_TIMEOUT
