Class HttpRequest

java.lang.Object
com.avoka.component.http.HttpRequest
Direct Known Subclasses:
DeleteRequest, GetRequest, PostRequest, PutRequest
public abstract class HttpRequest extends Object
Provides an abstract HttpRequest class enabling simpler use of the Apache HTTP Components library.

The default connection timeout is 10 seconds and socket read timeout is 60 seconds. Socket connections will also apply any JVM proxy settings automatically.

By default the maximum response read size is 16 MB. If the response is larger than this an IOException will be thrown. To increase the maximum read limit use the setReadLimit(int) method.

Since:
4.2.0

    • getContext

      public org.apache.http.client.protocol.HttpClientContext getContext()
      Gets the HttpClientContext The context stores details about the call to a server. It is useful in NTLM which has a fairly expensive authentication process. Once connected the authentication details are stored in the HttpClientContext and following HttpRequest calls do not need to be made. the process is as follows. Initially do a connection to a cheap service GetRequest. The execute() method creates the context. Create a new httpRequest with the expensive operation such as a PUT and call setContext(context)
      Returns:
      the HttpClientContext context
      Since:
      4.3.0

    • setContext

      public HttpRequest setContext(org.apache.http.client.protocol.HttpClientContext context)
      Sets the HttpClientContext The context stores details about the call to a server. It is useful in NTLM which has a fairly expensive authentication process. Once connected the authentication details are stored in the HttpClientContext and following HttpRequest calls do not need to be made. the process is as follows. Initially do a connection to a cheap service GetRequest. After the execute() method runs get the context. Create a new httpRequest with the expensive operation such as a PUT and call setContext(context)
      Parameters:
      context - the HttpClientContext from a previous HttpRequest call.

      the HttpRequest object
