Examples with HttpClientConnector org.wso2.transport.http.netty.contract.HttpClientConnector used on opensource projects

Example 1 with HttpClientConnector

use of org.wso2.transport.http.netty.contract.HttpClientConnector in project ballerina by ballerina-lang.

the class AbstractHTTPAction method send.

/**
 * Send outbound request through the client connector. If the Content-Type is multipart, check whether the boundary
 * exist. If not get a new boundary string and add it as a parameter to Content-Type, just before sending header
 * info through wire. If a boundary string exist at this point, serialize multipart entity body, else serialize
 * entity body which can either be a message data source or a byte channel.
 *
 * @param dataContext               holds the ballerina context and callback
 * @param outboundRequestMsg        Outbound request that needs to be sent across the wire
 * @param async                     whether a handle should be return
 * @return connector future for this particular request
 * @throws Exception When an error occurs while sending the outbound request via client connector
