A CLI tool to check sites for mixed content

This repo contains a tool called mixed-content-scanner that can help you find pieces of mixed content on your site. This is how you can use it:

mixed-content-scanner scan https://spatie.be

And of course our company site reports no mixed content.

Here's an example of a local test server that does contain some mixed content:

Support us

Installation

You can install the package via composer:

composer global require spatie/mixed-content-scanner-cli

How it works under the hood

When scanning a site, the tool will crawl every page. On all html retrieved, these elements and attributes will be checked:

• audio: src
• embed: src
• form: action
• link: href
• iframe: src
• img: src, srcset
• object: data
• param: value
• script: src
• source: src, srcset
• video: src

If any of those attributes start with http:// the element will be regarded as mixed content.

The tool does not scan linked .css or .js files. Inline <script> or <style> are not taken into consideration.

Usage

You can scan a site by using the scan command followed by the url

mixed-content-scanner scan https://example.com

Options

SSL verification

You might want to check your site for mixed content before actually launching it. It's quite common your site doesn't have an ssl certificate installed yet at that point. That's why by default the tool will not verify ssl certificates.

If you want to turn on ssl verification just use the verify-ssl option

mixed-content-scanner scan https://self-signed.badssl.com/ --verify-ssl

That examples will result in non responding urls because the host does not have a valid ssl certificate

Filtering and ignoring urls

You can filter which urls are going to be crawled by passing regex to the filter and ignore options.

In this example we are only going to crawl pages starting with /en.

mixed-content-scanner scan https://spatie.be --filter="^\/en"

You can use multiple filters:

mixed-content-scanner scan https://spatie.be --filter="^\/en" --filter="^\/nl"

You can also ignore certain urls. Here we are going to ignore all url's that contain the word opensource.

mixed-content-scanner scan https://spatie.be --ignore="opensource"

Of course you can also combine filters and ignores:

mixed-content-scanner scan https://spatie.be --filter="^\/en" --ignore="opensource"

Ignoring robots

By default, the crawler will respect robots data. You can ignore them though with the --ignore-robots option.

mixed-content-scanner scan https://example.com --ignore-robots

Custom User agent

By default, the crawler uses the underlying guzzle client for the user agent. You can override this value with the --user-agent option.

mixed-content-scanner scan https://example.com --user-agent='MyCustomCrawler'
