SOAP-S Messages

Introduction

The SoapServerApp uses SOAP-S-… messages to communicate with other applications (such as the LogicApp) to handle inbound SOAP/HTTP(S) requests received from an external SOAP/HTTP(S) Client.

The following LuaApp agents from the core n2svcd module handle messages from SoapServerApp.

SoapLuaService (handles inbound SOAP requests within LogicApp)

The internal SOAP-S-… messages are:

SOAP-S-REQUEST
SOAP-S-RESPONSE

Note that this page uses the term “on-the-wire” to refer to the sending or receiving of SOAP content by the SoapServerApp. This term is also inclusive of the case where the message is sent by local loopback and does not physically transit a Network Interface Controller (NIC).

SOAP-S-REQUEST

The SOAP-S-REQUEST message is sent by SoapServerApp to the application that is configured for handling of inbound SOAP requests.

Refer to the SoapServerApp Configuration documentation for more information on setting default parameters.

The attributes of the SOAP-S-REQUEST message are:

Field	Type	Description
`soap`	Object	Container for the parameters of the SOAP request that we have received.
`.remote_host`	String	The remote IP address from which the SOAP HTTP(S) request was sent.
`.remote_port`	Integer	The remote IP port from which the SOAP HTTP(S) request was sent.
`.method`	String	The HTTP Request method.
`.uri`	String	The URI for which the request was received. Includes only path and query. No host/port/auth/user/fragment is present.
`.path`	String	The URI path.
`.query`	String	The URI query string (the part following "?" in the URI).
`.message_name`	String	The name of the SOAP message (without namespace), being the name of the element contained within the SOAP body.
`.args`	Object	The args provided by the client into the SOAP request. This may be a complex, nested structure. The decoding and parsing of the args into an internal object representation differs slightly according the `quirks_mode`.
`.message_namespace`	Object	A container for the message namespace information.
`.location`	`message`/`envelope`	Location of the message namespace.
`.alias`	String	The alias for the message namespace, if one was used.
`.uri`	String	The message namespace URI, if one was provided.
`.standard_namespaces`	Object	A container for the standard namespace information.
`.encoding_alias`	String	The alias for the standard encoding namespace, if present.
`.envelope_alias`	String	The alias for the standard envelope namespace, if present.
`.schema_alias`	String	The alias for the standard schema namespace, if present.
`.schema_instance_alias`	String	The alias for the standard schema instance namespace, if present.
`.http_headers`	Array of Object	The list of HTTP headers parsed from the HTTP Request (see below for object structure). All HTTP headers are present, including `Content-Length` and `Content-Type`. If a HTTP header was repeated in the HTTP Request, then it is repeated in this Array.

Note that SSL and security parameters are not placed into this message.

Each object in the soap.http_headers Array for SOAP-S-REQUEST has the following structure.

Field	Type	Description
`.name`	`String`	[Required] The name of the HTTP Request header.
`.value`	`String`	[Required] The full string value of the HTTP Request header.

SOAP-S-RESPONSE

The SOAP-S-RESPONSE message is sent back to the SoapServerApp by the handling application when it is ready to send a HTTP Response to the original received HTTP Request.

The attributes of the SOAP-S-RESPONSE message are:

Field	Type	Description
`success`	`0`/`1`	[Required] Indicates if the request handling was successful or not.
`error`	String	Indicates the reason why the request handling failed. Present and applicable only if `success` == `0`.
`soap`	Object	Container for the SOAP response parameters we are to send. Present only if `success` == `1`.
`.message_name`	String	Response message name to use. (Default = Request name with `Response` appended)
`.args`	Object	The arguments which we will encode into XML for the SOAP response. The `quirks_mode` for the SoapServerApp will control how this is done.
`.http_headers`	`Array of Objects`	Additional user-level header objects to apply to an outbound HTTP Response (see below for object structure). These headers are added after any headers defined by static `RestServerApp` application configuration. You should not set the `Content-Type` or `Content-Length` headers. (Default = No Additional Headers)

Each object in the soap.http_headers Array for SOAP-S-RESPONSE has the following structure.

Field	Type	Description
`.name`	`String`	[Required] The name of the HTTP Response header.
`.value`	`String`	[Required] The full string value of the HTTP Response header.
`.replace`	`0` / `1`	If `1` then all previous headers of this name are removed, and this header replaces them. (Default = Append to the existing headers, do not replace)
