title: OAuth nonce value
body: <p>I am working with the <a href="http://platform.fatsecret.com/api/Default.aspx?screen=rapih" rel="noreferrer">FatSecret REST API</a></p>
  
  <p>Im using the <a href="https://github.com/jrconlin/oauthsimple/blob/master/js/OAuthSimple.js" rel="noreferrer">OAuthSimple</a> javascript library to generate the signed url. 
  Here's the code I have - </p>
  
  <pre><code>    params['oauth_timestamp'] = Math.floor(new Date().getTime()/1000);
      params['oauth_nonce'] = '1234';
      params['oauth_version'] = '1.0';
  
      var paramStr = '';
      for(var key in params){
          paramStr += key+"="+params[key]+"&amp;";
      }    
      paramStr = paramStr.substring(0,paramStr.length-1);
  
      var oauth = OAuthSimple();
      oauth.setAction('GET');
      var o = oauth.sign(
              {
               path:this.requestURL,
               parameters: paramStr,
               signatures:{
                  api_key:this.apiKey,
                  shared_secret:this.sharedSecret,
                  access_token: this.accessToken,
                  access_secret: this.accessSecret
               }
              });
      console.log(o.signed_url);
      return o.signed_url;
  </code></pre>
  
  <p>params is an associative array containing all the non oauth related parameters for this call. 
  When I use this signed url I get an "invalid/used nonce"</p>
  
  <p>The <a href="https://github.com/mashery/OAuth-1.0-JavaScript-Testing-Tool" rel="noreferrer">OAuth Testing Tool</a> uses the same OAuthSimple library and if I put in all the same parameters (including the timestamp) it generates exactly the same url. </p>
  
  <p>The only difference is that the url generated by the testing tool works and gives me the full response from the server. The url generated by my code does't. </p>
  
  <p>I tried various nonce values including sending a MD5 of the timestamp but I get the same error. The reason I'm using 1234 right now is that the testing tool uses 1234 by default and  that seems to work.</p>
  
  <p>Any help is appreciated. Thanks in advance.</p>
