node.js - Request within a request in nodejs -

i using request library in nodejs. need call new url within request not able join response asynchronouse. how send variable a in below request containing result of request within request.

 request({     url: url,     json: true }, function (error, response, body) {     var = [];     a.push(response);     (i = 0; < a.length; i++) {         if (a.somecondition === "rightcondition") {             request({                 url: url2,                 json: true             }, function (error, response, body) {                 a.push(response);             });         }     }     res.send(a); }); 

your code seems right want. sending response in wrong callback. move sends after second request has completed:

request({     url: url,     json: true }, function (error, response, body) {     var = [];     a.push(response);     request({         url: url2,         json: true     }, function (error, response, body) {         for(i=0;i<a.length;i++){             if(a.somecondition === "rightcondition"){                 a.push(response);             }         }         res.send(a); // send after last request     }); });
