How Can I Access HTTPS Pages with CasperJS/PhantomJS?

CasperJS/PhantomJS: Navigating HTTPS Pages

CasperJS and PhantomJS face limitations when accessing certain web pages, including those secured with HTTPS. The question arises whether the following page poses any issue: https://maizepages.umich.edu.

Addressing the SSLv3 Vulnerability

The error message "PhantomJS failed to open page status=fail" indicates a potential issue with SSLv3. Recent updates to PhantomJS (< v1.9.8) have removed SSLv3 support, which can prevent these browsers from loading pages that lack TLSv1 compliance. To resolve this, specify the SSL protocol explicitly using the --ssl-protocol flag:

casperjs --ssl-protocol=tlsv1 yourScript.js

For a more comprehensive solution, use the --ssl-protocol=any flag, which supports any available SSL protocol:

casperjs --ssl-protocol=any yourScript.js

Updating to PhantomJS 1.9.8 or Higher

Alternatively, updating to PhantomJS 1.9.8 or later will automatically resolve the SSLv3 conflict. However, this update introduces a new bug specifically affecting CasperJS.

Verifying the Issue

To confirm whether the SSLv3 vulnerability is causing problems, add a resource.error event handler to your script:

casper.on("resource.error", function(resourceError){
    console.log('Unable to load resource (#' + resourceError.id + ' URL:' + resourceError.url + ')');
    console.log('Error code: ' + resourceError.errorCode + '. Description: ' + resourceError.errorString);
});

If the error "Error code: 6. Description: SSL handshake failed" appears, this indicates an SSLv3 issue.

Additional Considerations

For cases involving SSL certificate issues, consider using the --ignore-ssl-errors=true flag to bypass certificate checks.
