Question

我用PB的图案装载如下:

var Schema = require( protobuf ).Schema;
var schema = new Schema(fs.readFileSync( /home/ubuntu/workspace/test.desc ));

然后,对于一个职位,我期望一个pb,我有以下内容。

   app.post( /mypost , function(req, res){

        var Feed = schema[ MyRequest ];
        var aFeed = Feed.parse(req.body);
        var serialized = Feed.serialize(aFeed);

   });

我比较新才才刚到结节 Js, 并获得邮资数据。 req. body 是邮资的缓冲吗?

Looking for specific examples for simple request response handling in http with nodejs. This should help you get to the parsing step. http://nodejs.org/api/all.html#all_class_http_serverrequest http://nodejs.org/api/http.html#http_event_data

例如:

var options = {
  host:  www.google.com ,
  port: 80,
  path:  /upload ,
  method:  POST 
};

var req = http.request(options, function(res) {
  console.log( STATUS:   + res.statusCode);
  console.log( HEADERS:   + JSON.stringify(res.headers));
  res.setEncoding( utf8 );
  res.on( data , function (chunk) {
    console.log( BODY:   + chunk);
  });
});

req.on( error , function(e) {
  console.log( problem with request:   + e.message);
});

// write data to request body
req.write( data
 );
req.write( data
 );
req.end();
