how to escape '=' character in ansible playbook

I have a playbook like this:

- name: make a http request
  shell: wget -O /dev/null http://my.site.com/some/url?with=args

The main problem is the GET Arguments. There is an "=" character that I don't know how to escape properly. If I do not escape this, ansible thinks that it's another argument for module, but if I escape it, then it make double escaping so as a result I've got "/=" in the shell.

Ansible version: 1.7.1

Thanks in advance!

With little help the problem was found.

Problem was actually in Ansible 1.7.1. After upgrading to 1.7.2 the problem was solved.

Thanks to everyone :)

I wasn't able to reproduce this with a bare call to wget. I'm using my gravatar as a URL with args. Here's a sample call.

TASK: [shell wget -O /dev/null https://www.gravatar.com/avatar/cad260683598a6e41608b91a9b57099b?s=24] ***

And here's the debugging output:

<hostname> REMOTE_MODULE command wget -O /dev/null https://www.gravatar.com/avatar/cad260683598a6e41608b91a9b57099b?s=24 #USE_SHELL
... connected.\nHTTP request sent, awaiting response... 200 OK\nLength: 1089 (1.1K) [image/jpeg]\nSaving to: `/dev/null'\n\n     0K .                                                     100% 1.93M=0.001s\n\n2014-10-31 16:52:00 (1.93 MB/s) - `/dev/null' saved [1089/1089]", "stdout": ""}

Generally speaking, using command, shell, and lineinfile are a form of code smell. In this case, it means using the get_url module or the uri module. wget generally implies get_url, but you are throwing away the output, so you are using it like curl, which means the uri module is better.

Here's my playbook. I needed to add pip since httplib wasn't installed on my test host.

  tasks:
  - debug: var=hostvars
  - pip: name=httplib2
    sudo: yes
  - uri: url=https://www.gravatar.com/avatar/cad260683598a6e41608b91a9b57099b?s=24

You can see in the verbose output that it's making the correct call.
