Constructor Details

#initialize(&block) ⇒ Client

Initializes the Savon::Client for a SOAP service. Accepts a block which is evaluated in the context of this object to let you access the wsdl, http, and wsse methods.

Examples

# Using a remote WSDL
client = Savon::Client.new { wsdl.document = "http://example.com/UserService?wsdl" }

# Using a local WSDL
client = Savon::Client.new { wsdl.document = "../wsdl/user_service.xml" }

# Directly accessing a SOAP endpoint
client = Savon::Client.new do
  wsdl.endpoint = "http://example.com/UserService"
  wsdl.namespace = "http://users.example.com"
end

  process 1, &block if block
  wsdl.request = http
end

Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(method, *args, &block) ⇒ Object (private)

Handles calls to undefined methods by delegating to the original block binding.

end

Instance Attribute Details

end

#request(*args, &block) ⇒ Object

Executes a SOAP request for a given SOAP action. Accepts a block which is evaluated in the context of this object to let you access the soap, wsdl, http and wsse methods.

Examples

# Calls a "getUser" SOAP action with the payload of "<userId>123</userId>"
client.request(:get_user) { soap.body = { :user_id => 123 } }

# Prefixes the SOAP input tag with a given namespace: "<wsdl:GetUser>...</wsdl:GetUser>"
client.request(:wsdl, "GetUser") { soap.body = { :user_id => 123 } }

# SOAP input tag with attributes: <getUser xmlns:wsdl="http://example.com">...</getUser>"
client.request(:get_user, "xmlns:wsdl" => "http://example.com")
