CSV file download from button click through POST request

[pilatus]

Hi.

 I want to download a CSV file, it is generated on a button click through a POST request. I researched to my best on casperJs and phantomJS forums and returned empty handed. It is too hard to believe that it is not supported. is there any nice trick though? pleas help

Thanks,

[pilatus]

Here are my response headers

Have you tried CasperJS download method?

Cheers,

Leandro

@Leandro There is no link generated to download the csv, the post request just returns the csv as an attachement. I wonder if casperJs download supports that

[Leandro Boscariol]

I understand.

I would suggest to ask on PhantomJS's mailing list, but they already have an old open issue for that (https://github.com/ariya/phantomjs/issues/10052).

I had the same issue, but I managed to find out a POST url address hidden inside the page to use the method mentioned before.

Sorry can't help you more on that :/

// Something like this:

 

var ignoreResources = true; // set false before querying for a file
var downloadFilename;

function fileLoader(casper, response) {
  if(ignoreResources || response.stage!="start" || response.contentType!="text/csv") return; // substitute right content type
//  console.log('Response (#' + response.id + ', stage "' + response.stage + '"): ' + JSON.stringify(response));
  casper.download(response.url, "files/"+downloadFilename); // correct the folder
  ignoreResources = true;
}

var casper = require('casper').create({
    loadImages:  false,
    loadPlugins: false,
    onResourceReceived: fileLoader,
});

 

// ...

    ignoreResources = false;

    downloadFilename = fileInfo.name;

    // click() here
// ...

I'm doing the same thing, with the download method, but I get a file with error, probably due to that I need to add a cookie or something.

Bottom line I can't generate the same request twice since each request has special parameters that I can't figure out.

Also, the steps I do is to click on a button that triggers file download in the browser, and I use:

casper.on('resource.received', function (resource) {

  //my code

}

I can see that the file is downloaded from the web, but I can't reach it...

The question is why I can't access the file...

Thanks
