Method Detail

setConfigurer

@Deprecated
public static void setConfigurer(HttpClientConfigurer newConfigurer)

Deprecated. use addConfigurer(HttpClientConfigurer)

Add a HttpClientConfigurer class used to configure the http clients.

addConfigurer

public static void addConfigurer(HttpClientConfigurer newConfigurer)

Add a HttpClientConfigurer to the list of configurers used to create http clients

removeConfigurer

public static void removeConfigurer(HttpClientConfigurer configurer)

Remove a HttpClientConfigurer from the list of configurers used to create http clients

resetConfigurers

public static void resetConfigurers()

createClient

public static org.apache.http.impl.client.CloseableHttpClient createClient(SolrParams params)

Creates new http client by using the provided configuration.

Parameters:

params - http client configuration, if null a client with default configuration (no additional configuration) is created.

createClient

public static org.apache.http.impl.client.CloseableHttpClient createClient(SolrParams params,
                                                                           org.apache.http.conn.ClientConnectionManager cm)

Creates new http client by using the provided configuration.

configureClient

public static void configureClient(org.apache.http.impl.client.DefaultHttpClient httpClient,
                                   SolrParams config)

Configures DefaultHttpClient, only sets parameters if they are present in config.

close

public static void close(org.apache.http.client.HttpClient httpClient)

addRequestInterceptor

public static void addRequestInterceptor(org.apache.http.HttpRequestInterceptor interceptor)

removeRequestInterceptor

public static void removeRequestInterceptor(org.apache.http.HttpRequestInterceptor interceptor)

setAllowCompression

public static void setAllowCompression(org.apache.http.impl.client.DefaultHttpClient httpClient,
                                       boolean allowCompression)

Control HTTP payload compression.

Parameters:

allowCompression - true will enable compression (needs support from server), false will disable compression.

setBasicAuth

public static void setBasicAuth(org.apache.http.impl.client.DefaultHttpClient httpClient,
                                String basicAuthUser,
                                String basicAuthPass)

Set http basic auth information. If basicAuthUser or basicAuthPass is null the basic auth configuration is cleared. Currently this is not preemtive authentication. So it is not currently possible to do a post request while using this setting.

setMaxConnectionsPerHost

public static void setMaxConnectionsPerHost(org.apache.http.client.HttpClient httpClient,
                                            int max)

Set max connections allowed per host. This call will only work when ThreadSafeClientConnManager or PoolingClientConnectionManager is used.

setMaxConnections

public static void setMaxConnections(org.apache.http.client.HttpClient httpClient,
                                     int max)

Set max total connections allowed. This call will only work when ThreadSafeClientConnManager or PoolingClientConnectionManager is used.

setSoTimeout

public static void setSoTimeout(org.apache.http.client.HttpClient httpClient,
                                int timeout)

Defines the socket timeout (SO_TIMEOUT) in milliseconds. A timeout value of zero is interpreted as an infinite timeout.

Parameters:

timeout - timeout in milliseconds

setUseRetry

public static void setUseRetry(org.apache.http.impl.client.DefaultHttpClient httpClient,
                               boolean useRetry)

Control retry handler

Parameters:

useRetry - when false the client will not try to retry failed requests.

setConnectionTimeout

public static void setConnectionTimeout(org.apache.http.client.HttpClient httpClient,
                                        int timeout)

Set connection timeout. A timeout value of zero is interpreted as an infinite timeout.

Parameters:

timeout - connection Timeout in milliseconds

setFollowRedirects

public static void setFollowRedirects(org.apache.http.client.HttpClient httpClient,
                                      boolean followRedirects)

Set follow redirects.

Parameters:

followRedirects - When true the client will follow redirects.

setHostNameVerifier

public static void setHostNameVerifier(org.apache.http.impl.client.DefaultHttpClient httpClient,
                                       org.apache.http.conn.ssl.X509HostnameVerifier hostNameVerifier)

setStaleCheckingEnabled

public static void setStaleCheckingEnabled(org.apache.http.client.HttpClient httpClient,

setTcpNoDelay

public static void setTcpNoDelay(org.apache.http.client.HttpClient httpClient,
                                 boolean tcpNoDelay)

createNewHttpClientRequestContext

public static org.apache.http.client.protocol.HttpClientContext createNewHttpClientRequestContext()

Create a HttpClientContext object and HttpClientContext.setUserToken(Object) to an internal singleton. It allows to reuse underneath HttpClient in connection pools if client authentication is enabled.
