Question

如何将两个Javascript值发送到xively feed，一个作为ID，一个作为值。目前的代码是。我希望将这些值添加到xively中，以便我可以通过带有wifi的arduino访问它们。不幸的是，从JS直接从网站获取值似乎并不简单，所以这是我的解决方法，除非有人有更好的方法从arduino访问这些数据。使用此示例作为参考例如我想从网站发送数据而不是检索它。 http://xively.github.io/xively-js/tutorial/

以下是向Feed中的两个频道（＆＃34; foo＆＃34;和＆＃34; bar＆＃34;）中的每一个发送单个值的简单示例...

   <script language="JavaScript" type="text/javascript">
      var API_KEY = "YOUR_API_KEY";
      var FEED_ID = "YOUR_FEED_ID";

      $(document).ready(function() {
         // Set your API key first
         xively.setKey(API_KEY);

         // build the data packet
         var timestamp = new Date().toISOString();
         var data = { "version" : "1.0.0",
            "datastreams" : [
               { "id" : "foo", "datapoints" : [ {"at" : timestamp, "value" : 10} ] },
               { "id" : "bar", "datapoints" : [ {"at" : timestamp, "value" : 20} ] }
            ]
         };

         // upload the data
         xively.feed.update(FEED_ID, data, function(response) {
            if (response.status == "200") {
               console.log("Yay, it worked!: " + JSON.stringify(response, null, 3));
            }
            else {
               console.log("Boo, something went wrong!: " + JSON.stringify(response, null, 3));
            }
         });

      });

Look in the console for output.
