The HTTP inbound adapter works identifying an Action and then defining a mapping between the Action and a Formatter.
 +
 +
The Action is defined by the value of the request parameter '''GV_ACTION''' '''(REMOVED in v3.4)'''.
 +
 +
The formatter defines how to parse the request parameters and how to build the response in case of successful or failed ESB's invocation.
 +
 +
The client can send HTTP requests at two url:
 +
* <pre>http://<host>:<port>/gvhttp/inbound/<action></pre>
 +
* <pre>http://<host>:<port>/gvhttp/secure/inbound/<action>    (requires authentication)</pre>

Description

The HTTP inbound adapter works identifying an Action and then defining a mapping between the Action and a Formatter.

The Action is defined by the value of the request parameter GV_ACTION (REMOVED in v3.4).

The formatter defines how to parse the request parameters and how to build the response in case of successful or failed ESB's invocation.

The client can send HTTP requests at two url: 

  • http://<host>:<port>/gvhttp/inbound/<action>
  • http://<host>:<port>/gvhttp/secure/inbound/<action>    (requires authentication)
