I try to use socket.http to send a SOAP message with POST in the body of
http.
See the following code:
local http = require("socket.http")
body = [[<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance";
xmlns:xsd="http://www.w3.org/2001/XMLSchema";
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/";>
<soap:Body>
<ViewLogStatus
xmlns="http://www.thermo.com/informatics/xmlns/limswebservice"; />
</soap:Body>
</soap:Envelope>]]
local r,c,h = http.request{
url = "http://xx/LimsWebService/default.asmx?op=ViewLogStatus";,
sink = ltn12.sink.file(io.open("test.out", "w")),
headers = {
["Content-Type"] = "text/xml; charset=utf-8",
["content-length"] = tostring(body:len()),
["SOAPAction"]="\"http://www.thermo.com/informatics/xmlns/limswebservice/ViewLogStatus\"";
["Host"] = "xx",
},
body = ltn12.source.string(body),
method = "POST"
}
This leads always to a timeout and using a wireshark i can see the http
headers only - no body.
I tried a 'trick' to insert the body in the header telegram:
local r,c,h = http.request{
url = "http://xx/LimsWebService/default.asmx?op=ViewLogStatus";,
sink = ltn12.sink.file(io.open("test.out", "w")),
headers = {
["Content-Type"] = "text/xml; charset=utf-8",
["content-length"] = tostring(body:len()+4),
["SOAPAction"] =
"\"http://www.thermo.com/informatics/xmlns/limswebservice/ViewLogStatus
\"",
["Host"] = "xx\r\n\r\n\r\n"..body
},
method = "POST"
}
This works (more or less) and the server is responding.
Do I misunderstand something with the first (the 'official') version?
Is there a known bug?
Any help is welcome.
