Why Does PhantomJS/CasperJS Fail to Load HTTPS Pages and How Can I Fix It?

PhantomJS/CasperJS Fails to Load HTTPS Page: A Comprehensive Solution

Encountering "PhantomJS failed to open page status=fail" errors while attempting to open HTTPS websites can be frustrating. This issue arises from PhantomJS's default use of SSLv3, which has recently been discovered to have a vulnerability known as POODLE. Websites have responded by removing SSLv3 support.

Solution:

1. Update to PhantomJS 1.9.8 or Higher: This version introduces TLSv1 support by default, addressing the SSLv3 vulnerability.

2. Use TLSv1 Explicitly: If you're using an older version of PhantomJS, specify TLSv1:

   casperjs --ssl-protocol=tlsv1 yourScript.js

3. Use "Any" Protocol: To accommodate future changes in SSL protocols, use "any":

   casperjs --ssl-protocol=any yourScript.js

Additional Tips:

• Add a resource.error event handler to your script to identify any loading failures.
• Consider using --ignore-ssl-errors=true to ignore certificate issues.
• If the error persists, verify that the website in question supports TLSv1.

Verification:

If the issue relates to SSLv3, you should encounter an error like:

Error code: 6. Description: SSL handshake failed

By implementing these solutions, you can effectively resolve issues related to loading HTTPS pages in CasperJS/PhantomJS.
