[oauth] OAuth JS API results in signature_invalid at random

[Matt Raible]

Hello,

I'm trying to use the JavaScript API to authenticate with OAuth from a
GWT application. I've got it working with both Google and Twitter's
OAuth implementations. However, it seems to fail to sign the URL at
random. In other words, it works 1 out of 3 times.

I'm using the following makeSignedRequest() function to create the
signed URL.

<script type="text/javascript">
        var makeSignedRequest = function(ck, cks, ts, encodedurl) {
            var accessor = { consumerSecret: cks, tokenSecret: ts};
            var message = { action: encodedurl, method: "GET",
parameters: [
                ["oauth_version","1.0"],
                ["oauth_consumer_key",ck]
            ]};

            OAuth.setTimestampAndNonce(message);
            OAuth.SignatureMethod.sign(message, accessor);

            var parameterMap = OAuth.getParameterMap(message);
            var baseStr = OAuth.decodeForm
(OAuth.SignatureMethod.getBaseString(message));
            var theSig = "";

            if (parameterMap.parameters) {
                for (var item in parameterMap.parameters) {
                    for (var subitem in parameterMap.parameters[item])
{
                        if (parameterMap.parameters[item][subitem] ==
"oauth_signature") {
                            theSig = parameterMap.parameters[item][1];
                            break;
                        }
                    }
                }
            }

            var paramList = baseStr[2][0].split("&");
            paramList.push("oauth_signature=" + theSig);
            paramList.sort(function(a, b) {
                if (a[0] < b[0]) return -1;
                if (a[0] > b[0]) return 1;
                if (a[1] < b[1]) return  -1;
                if (a[1] > b[1]) return 1;
                return 0;
            });

            var locString = "";
            for (var x in paramList) {
                locString += paramList[x] + "&";
            }

            return baseStr[1][0] + "?" + locString.slice(0,
locString.length - 1);
        };

    </script>

Any idea why this could be happening?

Thanks,

Matt
