Direct Web Request component URL

Table of Contents

Description

Allows you to perform HTTP and HTTPS requests to Web services by arbitrary URL.
Supports HTTP methods GET, POST, PUT, HEAD, DELETE with and without content. Supports sending asynchronous requests and requests with pending responses.
In case of an error, the transition is made along the "Error" branch, and the corresponding code is returned to the "Error code" variable HTTP.
The component supports working in sessions, storing and using cookies, as well as HTTPS and certificate validation.

The actual sending of the request can be done either from the server on which the current script handler is running, or from the system’s edge servers «Incoplax».

In some cases can be replaced by executing a "curl" request via the command line (component Start process).

By default, the request is sent from the server where the handler executes the script.
Possible indication formats:

  • NodeName

  • NodeName:Iface

  • NodeName@NodeAddr

  • NodeName@NodeAddr:Iface

  • RoleId

  • RoleId:Iface

  • RoleName

  • RoleName:Iface

where

  • NodeName – the short name of the node in its full name (abc002@192.168.0.12);

  • NodeAddr – node address in its full name;

  • RoleId – role identifier in the configuration, the node is defined by the role;

  • RoleName – name of the role in the configuration, the node is defined by the role;

  • Iface – address of the network interface on the server.

If there is no node/role, any incorrect name assignment, the dispatch is done from the server where the handler executes the script.

If the sender server network interface address is missing or incorrectly specified, sending will be done from the sender node address.
