 var urls = [website ur names]   for(var j=0;j<urls.length;j++){           alchemyapi.feeds("url",urls[j], {}, function(response) {                       console.log(response["feeds"]);                       for(var i=0;i<response["feeds"].length;i++)                          var feed = response["feeds"][i].feed;                          getfeed(feed);                          console.log("title: " +objtostring(response["feeds"][i]));          });  }  function objtostring (obj) {      var str = '';      (var p in obj) {          if (obj.hasownproperty(p)) {              str += p + '::' + obj[p] + '\n';          }      }      return str;  }  var request = require('request');  var getfeed = function(feed){    feeds = encodeuricomponent(feed);  request('http://cloud.example.com/v3/mixes/contents?streamid=feed/'+feeds/, function (error, response, body)   {    if (!error && response.statuscode == 200)     {      console.log(body)      }    else     {      console.log("error "+response.statuscode)    }  });  }

var urls = [website ur names]  var request = require('request');  function promiserequest(feeds){   return new promise(function(resolve,reject){     request('http://cloud.example.com/v3/mixes/contents?streamid=feed/'+feeds/,                     function (error, response, body)          {       if (!error && response.statuscode == 200)        {         resolve(body);       }       else        {         reject(response.statuscode)；       }     });   } }  function getfeedsfromurls(urls){     return new promise(function(resolve,reject){         var count=0,totalcount = urls.length;         var result=[];         for(var j=0;j<urls.length;j++){              alchemyapi.feeds("url",urls[j], {}, function(response) {                  for(var i=0;i<response["feeds"].length;i++)                     var feed = response["feeds"][i].feed;                     promiserequest(feed).then(function(data){                         count++;                         result.push(data);                         if(count>=totalcount){                             resolve(result);                         }                     }).catch(function(err){                         count++;                         if(count>=totalcount){                             resolve(result);                         }                     });              });         }     }); }  getfeedsfromurls(urls).then(function(result){     console.log(result); })
