Issues getting CasperJS to upload image to file field - tried CasperJS fill() and PhantomJS uploadFile()

问题

I'm trying to use CasperJS to upload images to a web-form.

My form looks something like this:

<form action="" method="POST" enctype="multipart/form-data" class="form-vertical">
    ...                        
        <legend>Campaign Banner</legend>
        <div class="control-group image-field ">
            <label class="control-label">Now Large</label>
            <div class="controls">
                <div class="file-field"><input id="id_now_large_image" name="now_large_image" type="file"></div>
                <div class="image-preview"></div>
                <div class="clear"></div>
                <span class="help-inline"></span>
            </div>
        </div>
        <div class="control-group image-field ">
            <label class="control-label">Now Medium</label>
            <div class="controls">
                <div class="file-field"><input id="id_now_medium_image" name="now_medium_image" type="file"></div>
                <div class="image-preview"></div>
                <div class="clear"></div>
                <span class="help-inline"></span>
            </div>
        </div>
        <div class="control-group image-field ">
            <label class="control-label">Now Small</label>
            <div class="controls">
                <div class="file-field"><input id="id_thumbnail_image" name="thumbnail_image" type="file"></div>
                <div class="image-preview now-small"></div>
                <div class="clear"></div>
                <span class="help-inline"></span>
            </div>
        </div>

The submit button looks like this:

<div class="form-actions">
    <button type="submit" class="btn btn-small ui-button ui-widget ui-state-default ui-corner-all ui-button-text-only" role="button" aria-disabled="false"><span class="ui-button-text">Save changes</span></button>
</div>

I've put a Gist of the full HTML here: https://gist.github.com/victorhooi/8277035

First, I've tried using CasperJS's fill method:

    this.fill('form.form-vertical', {
        'now_large_image': '/Users/victor/Dropbox/CMT Test Resources/Test Banners/Default Banners/now_large.jpg',
    }, false);
    this.click(x('//*[@id="content-wrapper"]//button/span'));

I also did a this.capture(), and I saw that the file field had been filled in:

I'm not using the fill method's inbuilt submit, but I'm clicking on the submit button myself:

this.click(x('//*[@id="content-wrapper"]//button/span'));

I then do another capture, and I can see that the form has been submitted:

However, the image doesn't seem to have been uploaded at all.

I've also tried using PhantomJS's uploadFile() method:

this.page.uploadFile('input[name=now_large_image]', '/Users/victor/Dropbox/CMT Test Resources/Test Banners/Default Banners/now_large.jpg');

and then clicking on the submit button as well.

Same issue - the form field gets filled in - however, the image itself doesn't seem to get submitted.

Any ideas on how I can get the images to upload correctly here?

回答1:

Since you are filling and submitting successfully, try a Wait command on the click.

casper.then(function() {
    //+++ form fill here

    //waits 1 sec
    this.wait(1000, function() {
        this.click(x('//*[@id="content-wrapper"]//button/span'));
    });
});

Try this.

casper.thenOpen('about:blank', function(){
    this.evaluate(function(){
        var action = 'upload.php'
        var html = '<form action="'+action+'" method="post" enctype="multipart/form-data">'
        html += '<input type="file" name="files[]" multiple="multiple">'
        html += '<button type="submit">Submit</button>'
        html += '</form>'
        document.write(html)
    })
    this.fill('form',{
        'files[]': 'file.txt'
    }, true)
    this.waitFor(function(){
        var uri = casper.evaluate(function(){
            return document.documentURI
        })
        if ( 'about:blank' === uri ){
            return false
        }
        return true
    })
})
