How to connect REST api using Meteorjs

[Ashutosh Das]

Suppose my REST root url is

localhost:1000

and URI is " POST /users.json" and parameter are id and key ..

Already I tried this  

var result = Meteor.http.call("POST", url, { params: { key: appkey ,id: "xa4" }}) ;
console.log(result);

but it shows ; 
[13:34:43.190] Error: Can't make a blocking HTTP call from the client; callback required. @ http://localhost:1000/packages/http.js?4aec4250e79a92408f1c5e234a52434907239586:153

Hi!

You should provide a callback to Meteor.http when using it on the client.

Hi!

And what is in error argument?


Mitar

[Ashutosh Das]

Hi ,

Do you mean output of "err" ?

By the way I am following this document http://docs.prediction.io/current/apis/user.html .

[Mitar]

Hi!

When you are debugging it is useful to inspect all values you get. If
something does not work, maybe there is an error. Check what it says.

[Ashutosh Das]

It just shows  [object Error]

Hi!

Click on it.

FWIW, whenever I hit an 3rd-party API, I use the 'request' NPM package. You can use NPM packages in Meteor with the 'npm' meteorite package.

HTH,

+1 for 'request'.

If the REST API is chatty or verbose it's response might come over in multiple packets, which means that the receiving node will need to piece together the packets.  So 'request' is better than Http.get() in that regard; but it requires that you run it on the server.  

Before you go down that rabbit hole, however, check that the API is responding correctly to a REST API client.  Make sure there are no proxies, firewalls, etc.  Check the error message like Mi Tar suggests. etc. etc.

Hi!

You cannot make HTTP request from the client to another origin just so. That is, you cannot make HTTP requests from the client served from one host (like localhost) to another (like the API host) without the help of that another host.

All of you guys, I really thank you.

Solved the problem.

Hi!

So, what was the problem and what was the solution? It is nice to share with the rest, so that any future reader who come upon this thread over the Internet can know how to fix it as well.

Here is the solution :
I run my REST API server in localhost . I just make a mistake that , I call Meteor.http.call from (Meteor.isClient) block. The solution is simple , just call this code from Meteor.isServer block  and return the responce object to Meteor.isClient

[Mitar]

Hi!

You have to run on both same host and port number. It is not enough
that you run just on localhost for client side HTTP requests to work.
It is still cross-origin.

Server side does not have this security in place, so this is why you can access.

For those using the 'request' npm package, you may want to check out 'hyperquest':

https://github.com/substack/hyperquest

It introduces a fix for the "5 http calls at a time" limit.  (btw, I read on HN that that limit is fixed in node 0.11)

[Arunoda Susiripala]

We can simply remove this limit with.

Npm.require('http').globalAgent.maxSockets = 9999 //to some high value

[Arunoda Susiripala]

I think there is no reason to avoid meteor's HTTP unless you need something it doesn't have (like oauth signing, streaming capabilities)
