SoapAction can't add \"

Question

Hi,

I would like to send a XMLHttpRequest with SOAPACTION, such as "urn:schemas-upnp-org:service:ContentDirectory:1#Browse".

Sure, I tried to send a request to DLNA server, but only Windows Media Player success.

I captured packets to compare with other program, and I found a slight difference from my SOAPACTION.

Here are the two SOAPACTION strings of 2 packets:

1. My packet

SOAPACTION: urn:schemas-upnp-org:service:ContentDirectory:1#Browse

2. TrueLink+ packet

SOAPACTION: "urn:schemas-upnp-org:service:ContentDirectory:1#Browse"

if I browsed WMP server, my program can work properly. However, other DMS will return "Internal server error" and XML which tells me "Invalid Action".

So I imitated TrueLink SOAPACTION. Unfortunately, when I add \" both in head and end of SOAPACTION, the sent packet won't have SOAPACTION,

e.g. SOAPACTION = "\"urn:schemas-upnp-org:service:ContentDirectory:1#Browse\"";

I have tried WinJS.xhr and XMLHttpRequest(), the situations are the same.

Can anyone tell me what I neglect?

Answer 1

Can you please post your code of how you are setting this header?

// WinJS
var header = {
            'Content-Type': 'text/xml; charset="utf-8"',
            'SOAPACTION': '\"urn:schemas-upnp-org:service:ContentDirectory:1#Browse\"'
};
//Url and xml are worked when send to WMP server.

WinJS.xhr({ type: "POST", url: Url, headers: header, data: xml }).done(//callback code);

// Use XMLHttpRequest(), the result is the same as WinJS.
var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function (state) { }
xhr.onerror = function (err) { }
xhr.open("POST", Url, true);
xhr.setRequestHeader("Content-Type", "text/xml");
xhr.setRequestHeader("charset", "utf-8");
xhr.setRequestHeader('SOAPACTION', '\"urn:schemas-upnp-org:service:ContentDirectory:1#Browse\"');
xhr.send(xml);

It seems "u or "U that are not allowed in SOAPACTION.

Thank you Jeff.

Hi~

Any comment?

Answer 4

This problem is no doubt a bug of IE10.

I have tried with streamSocket, then I can correctly to send the headers.

And I have tried the same Javascript code in IE(desktop) occurs the same situation.

Can this bug be fixed?

Answer 5

The issue appears to occur when you quote the string for the header value.

I have not found a workaround yet!

Answer 6

Can you get away with a single quote?

 var action = "\'" + "urn:schemas-upnp-org:service:ContentDirectory:1#Browse" + "\'";
            var header = {
                "SOAPACTION": action
            };
