PhantomJS/CasperJS Struggles with HTTPS Page Load
When attempting to load a secure HTTPS page using PhantomJS/CasperJS, users may encounter the error "PhantomJS failed to open page status=fail." Addressing this issue requires a specific strategy to tackle SSLv3 vulnerabilities.
Error Analysis
Recent discoveries of the POODLE SSLv3 vulnerability have prompted website owners to disable SSLv3 support on their sites. However, since PhantomJS versions prior to 1.9.8 utilize SSLv3 by default, accessing such websites can lead to load failures.
Solution
To resolve this issue, specify the use of TLSv1 protocol when invoking PhantomJS:
casperjs --ssl-protocol=tlsv1 yourScript.js
For a more comprehensive solution that can accommodate future PhantomJS versions with different SSL protocols, use the following:
casperjs --ssl-protocol=any yourScript.js
Alternative Approach
Alternatively, update to PhantomJS 1.9.8 or higher to avoid SSLv3 vulnerability issues. However, this may introduce a different bug that affects CasperJS.
Verification
To verify if SSLv3 is the underlying issue, implement a resource.error event handler in your CasperJS 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 message displayed includes "Error code: 6. Description: SSL handshake failed," it is likely an SSLv3-related issue.
Additional Tip
For certificate-related errors, consider utilizing the --ignore-ssl-errors=true command-line option.
