Trouble http POST vs. GET

Sun Dec 28, 2014 4:32 pm

I'm having an issue with handling an http 'POST' to my script. When I post to my script using an http 'GET', all works perfectly. Here is a sample of my code:

// Get request parameters

var requestParams = {},
paramKeys = request.keys();
for (var key = 0; key < paramKeys.length; key++) {
requestParams[paramKeys[key]] = request.get(paramKeys[key]);
}

//Log parameters

console.log(JSON.stringify(request));

// Parse and set call values from request parameters

var CallSid = requestParams['CallSid'];

Here is the trace:

28.12.2014, 11:14:12 AM: {"params":{"AccountSid":"ACc4059745e60b37d8dd91a2a19199af5b","ToZip":"29579","FromState":"SC","Called":"+18433531264","FromCountry":"US","CallerCountry":"US","CalledZip":"29579","Direction":"inbound","FromCity":"CHARLESTON","CalledCountry":"US","CallerState":"SC","CallSid":"CA8ec4c1f8bff675a038ee2f0a900d3928","CalledState":"SC","From":"+18437371245","CallerZip":"29424","FromZip":"29424","ApplicationSid":"APbf3bb539960b0d3644b9a3f455520244","CallStatus":"ringing","ToCity":"MYRTLE BEACH","ToState":"SC","CallerName":"S CAROLINA CALL","To":"+18433531264","ToCountry":"US","CallerCity":"CHARLESTON","ApiVersion":"2010-04-01","Caller":"+18437371245","CalledCity":"MYRTLE BEACH"},"user":null,"method":"GET","requestBody":"","requestMimeType":null}

My code pulls 'CallSid' out of the request parameters perfectly when sent as a 'GET'.

Here is the trace when sent as a 'POST':

{"params":{},"user":null,"method":"POST","requestBody":"AccountSid=ACc4059745e60b37d8dd91a2a19199af5b&ToZip=29579&FromState=SC&Called=%2B18433531264&FromCountry=US&CallerCountry=US&CalledZip=29579&Direction=inbound&FromCity=CHARLESTON&CalledCountry=US&CallerState=SC&CallSid=CA305259034cadfee0f830b0537ee716a5&CalledState=SC&From=%2B18437371245&CallerZip=29424&FromZip=29424&ApplicationSid=APbf3bb539960b0d3644b9a3f455520244&CallStatus=ringing&ToCity=MYRTLE+BEACH&ToState=SC&CallerName=S+CAROLINA+CALL&To=%2B18433531264&ToCountry=US&CallerCity=CHARLESTON&ApiVersion=2010-04-01&Caller=%2B18437371245&CalledCity=MYRTLE+BEACH","requestMimeType":"application/x-www-form-urlencoded;charset=\"UTF-8\""""}

My code fails to pull 'CallSid'.

I'm a newbie with javascript and I'm sure it's an easy fix. Any suggestions?

Thanks!"

Hi Thomas,

As i can see your "CallSid" exists in two requests. See details: http://prntscr.com/5m2lhm/direct

Try following JS code to access this parameter when with post:

pre

var CallSid = request.params['CallSid'];

/pre

Regards.

Not sure you understand based on your reply. There are not 2 requests. My twilio app is sending the request based on a phone call to my app. I can set twilio to send the request as either a GET or a POST. I gave you an example of each request.

My code works perfectly when twilio sends a GET request but fails when a POST request is sent.,

I tried your code and it does not work with POST. The trace shows:

Script AS_1_initial_greeting: Error: Empty objects can't be created. Please specify at least one field. ( @ 37 : 18 ) - throw e;

It appears to me that the body of the request in a POST is not being parsed by my code or yours.

I have shared the script with you.

I am having a similar problem with my app.
Can send by GET, but not by POST.
This only happened since last update.
Everything before the update was working fine.

Hello,

Ok, i tried, and here is code to get post parameters:

precode

var postParameters = {};

var requestBody = request.requestBody;
var bodyComponents = requestBody.split("&");
for(var i = 0; i < bodyComponents.length; i++){
var parameter = bodyComponents.split("=");

Code: Select all

postParameters[parameter[0]] = parameter[1];

};

//Using post parameters. Check trace tab.
console.log(JSON.stringify(postParameters));

/code/pre

Regards.
