javascript - Is it possible to forward a stream from one function to another? -

-

Please take a look at the following sample code.

As you can see, it uses parsing to write incoming form data and incoming files on disk. Let's say that these are just image files because my sample code uses imgur.com. (Does not require sending a content length header) uses the imgurUpload () function

Is it possible to extend additional image files, without having to buffer them to complete Need .com? (Use it on the ImgurUpload () function and within node-form-data?)

Server / Listener: 

  var http = need ('http'), Basubi = ('Busboy'), formdata = is required ('form-data'), fs = 'required' ('fs') http.createServer (function (req, res) {if (req.method = ('File', 'file', function (field name, file, file name, encoding, mimetype) (Fs.createWriteStream ('1-' + filename)) // pipe the second time to file.pipe (fs.createWriteStream ('2-' + F) *) * * * How to connect things together? * Busby.on ('Res'writeHead' (200, {'connection': 'off'}) res.end ("full upload") }) Return to the Recovery (return) and if (req.method == = 'GET') {var stream = fs.createReadStream (__DERNAM + '/ index HTM') stream.pipe (res)}}) . Listen (80, function () {console.log ('listen to requests'}})   
 HTML test form (index.html)  
  & Lt ;! Doctype html & gt; & Lt; Top & gt; & Lt; / Head & gt; & Lt; Body & gt; & Lt; Form Action = "/ Upload" method = "Post" Encrypt = "Multipart / Form-Data" & gt; & Lt; input type = "file" name = "file" & gt; & Lt; Input type = "submit" value = "submit" & gt; & Lt; / Form & gt; & Lt; / Body & gt; & Lt; / Html & gt;  
  function imgurUpload (stream) {var form = new form data append ('filatata', FSCTRstream ('test.jpg')) form.append ('filatadet', / * How to connect things together? * / X) form.submit ('http://imgur.com/ upload', function (mistake, race) {if (mistake) disturbs var body = '' res .on ('data', function (piece) {body + = chunk}) res.on ('end', function () {console.log ('http://imgur.com/' + JSON.parse (body ) .data.hash)})})

  _stream_readable.js: 748 new error ('now' Can not be switched on Rane mode. "); ^ Error: can not switch to old mode anymore.

 You can add readable streams as shown in the  node-form-data  redemption, then it:  
  form.append ('filedate', stream );   
 should work fine now.  
 Then in your  file  event handler:  
  imgurUpload (file);

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i

I am trying to create Java web framework (and learning), and on the basis of 'Code Generator In the process of making the material view of the database in the process of development, I stumbled into a difficulty, which I do not know how to solve it.
