README

WSDL to Go


Generates Go code from a WSDL file.

Install

• Download binary release
• Or: go get github.com/hooklift/gowsdl/...

Goals

• Generate idiomatic Go code as much as possible
• Support only Document/Literal wrapped services, which are WS-I compliant
• Support:
  • WSDL 1.1
  • XML Schema 1.0
  • SOAP 1.1
• Resolve external XML Schemas
• Support external and local WSDL

Caveats

• Please keep in mind that the generated code is just a reflection of what the WSDL is like. If your WSDL has duplicated type definitions, your Go code is going to have the same and may not compile.

Usage

Usage: gowsdl [options] myservice.wsdl
  -o string
        File where the generated code will be saved (default "myservice.go")
  -p string
        Package under which code will be generated (default "myservice")
  -v    Shows gowsdl version
