wkhtmltopdf仅对具有错误HostNotFoundError的本地文件失败

Question

I'm having some trouble with a new install of wkhtmltopdf v0.12.1 64bit on CentOS6

This works perfectly:

/usr/local/bin/wkhtmltopdf http://google.com/ temp.pdf

But the following command fails with HostNotFoundError (where domain.com is the domain of the php file running the shell script):

/usr/local/bin/wkhtmltopdf http://domain.com/ temp.pdf

The same is true for any html file on the domain. Domain.com is resolving normally via a web browser. Also, trying to convert other webpages on different domains which are hosted on the same server works fine.

Any ideas what might be wrong? I suspect something surrounding the server firewall or the user account under which php runs but I can't figure it out.

Answer 1

After a lot of searching today I found a solution for this problem. It turns out it has the same root as a common issue running file_get_contents() on a local file. Here is the fix:

Modify PHP.ini to enable the following:

extension = php_openssl.dll  //remove the ; to uncomment (enable) this line

allow_url_fopen = on

Hopefully this will help someone else out!
