soapproxy

A simple SOAP <-> gRPC proxy.

1. Generate the WSDL

with ./protoc-gen-wsdl:

protoc --wsdl_out=myproxy -I $GOPATH/src $GOPATH/src/unosoft.hu/ws/bruno/pb/dealer/dealer.proto

will create myproxy/dealer.wsdl and myproxy/dealer.wsdl.go.

2. Generate the Client code

with github.com/UNO-SOFT/gprcer/protoc-gen-grpcer:

protoc --grpcer_out=myproxy -I $GOPATH/src $GOPATH/src/unosoft.hu/ws/bruno/pb/dealer/dealer.proto

will create myproxy/dealer.grpcer.go, with grpc.Client implementation in it.

3. Profit!

Then use the SOAPHandler in myproxy/main.go (see ./example/example.go):

cc, err := grpcer.Connect("grpc-host:port", "ca.pem", "localhost")
if err != nil {
	log.Fatal(err)
}
http.ListenAndServe(
	":8080",
	soapproxy.SOAPHandler{Client:NewClient(cc), WSDL:soapproxy.Ungzb64(WSDLgzb64)},
)

Functions

func FilterEmptyTags

func FilterEmptyTags(w io.Writer, r io.Reader) error

func FindBody

func FindBody(dec *xml.Decoder) (xml.StartElement, error)

FindBody will find the first StartElement in soap:Body

func Ungzb64

func Ungzb64(s string) string

Ungzb64 decodes-decompresses the given gzipped-base64-encoded string. Esp. useful for reading the WSDLgzb64 from protoc-gen-wsdl embedded WSDL strings.

Types

type SOAPHandler

type SOAPHandler struct {
	grpcer.Client
	WSDL      string
	Log       func(keyvals ...interface{}) error
	Locations []string
}

SOAPHandler is a http.Handler which proxies SOAP requests to the Client. WSDL is served on GET requests.

func (SOAPHandler) ServeHTTP

func (h SOAPHandler) ServeHTTP(w http.ResponseWriter, r *http.Request)
