如何使用Meteor的WebApp访问HTTP POST正文（表单数据）？ 还是其他？

Question

I already tried server-routing with Iron Router, but that doesn't work. Then I discovered WebApp, which seems like it's supposed to handle this.

But when I inspect the req object:

WebApp.connectHandlers.use("/api/add", function( req, res, next ) {
    console.log( req );
    res.writeHead(200);
    res.end("Hello world from: " + Meteor.release);
});

I don't see any of my POST form-data. There's no body property, and I don't see the data itself anywhere under any other property.

How can I access this data? I'm going crazy trying to figure out something I thought would be relatively simple...

Answer 1

Yeah, I had the same issue. With connect, the post body isn't automatically in the request object. You can use middleware like this https://stackoverflow.com/a/24122700/5203563 or get it yourself like this:

WebApp.connectHandlers.use("/api/add", function( req, res, next ) {

  var body = "";
  req.on('data', Meteor.bindEnvironment(function (data) {
    body += data;
  }));

  req.on('end', Meteor.bindEnvironment(function () {
    console.log(body);
    res.writeHead(200);
    res.end("Hello world from: " + Meteor.release);
  }));
});

You will need to user fibers for the example to work, or I usually use picker you could add it meteor add meteorhacks:picker it's wrapper on top of webApp https://atmospherejs.com/meteorhacks/picker

and your example should work this way:

Picker.route('/api/add', function(params, req, res, next) {
    console.log( req );
    res.writeHead(200);
    res.end("Hello world from: " + Meteor.release);
});

here is an awesome article showing you the different options ( webApp with fibers as well) http://meteorpedia.com/read/REST_API
