Question

I want to pass parameters to an url using post method in hyperledger composer, but i didn't found any example of it. I only found one example in sample code of composer..

 function handlePost(postTransaction) {
 var url = 'https://composer-node-red.mybluemix.net/compute';

  return post( url, postTransaction)
  .then(function (result) {
    // alert(JSON.stringify(result));
      postTransaction.asset.value = 'Count is ' + result.body.sum;
      return getAssetRegistry('org.example.sample.SampleAsset')
      .then(function (assetRegistry) {
          return assetRegistry.update(postTransaction.asset);
      });
  });

}

typed Typed
The typed instance to be posted. The instance will be serialized to JSON.

There is now an experimental feature in the Composer code to solve this problem - the post you are using can be replaced by using the request module from NodeJS The details are in the following 2 docs on Github:
