“Mixed content blocked” when running an HTTP AJAX operation in an HTTPS page

I've a form which I'm submitting (through GET as it is required this way) to a crm (ViciDial). I can successfully submit the form however if I do that the processing file at crm will just echo a success text and that's it.

Instead of that text, I want to display a thank-you page on my website, so I decided to use AJAX to submit the form and redirect it to the page I need, however I'm getting this error on my browser:

Mixed Content: The page at 'https://page.com' was loaded over HTTPS, but requested an insecure XMLHttpRequest endpoint 'http://XX.XXX.XX.XXX/vicidial/non_agent_api.php?queries=query=data'. This request has been blocked; the content must be served over HTTPS.

This is my AJAX script:

    <script>
    SubmitFormClickToCall = function(){

        jQuery.ajax({
            url: "http://XX.XXX.XX.XX/vicidial/non_agent_api.php",
            data : jQuery("#form-click-to-call").serialize(),
            type : "GET",
            processData: false,
            contentType: false,
            success: function(data){
                window.location.href = "https://www.example.com/thank-you";
            }
        });
    }
    </script>

Just setting https in the URL won't work, is there any way in which I can submit the data via GET and redirect the user to my thankyou page?

============================

Problem here was mixed content, this means that I loaded a page through HTTPS and was trying to hit via AJAX an API that was in HTTP. But the browser wont allow us to just do that.

So if you can't set the API to be HTTPS (this was my case) we can still approach this in a different way.

The Main Problem was not the mixed content issue it was that I wanted to submit data to an API and redirect the users to a fancy thank you page. Instead of using AJAX, i made a php file that receives the data sends it using curl to the API (as this is being done server side there is no mixed content issue) and redirects my happy user to a fancy thank you page.

If you load a page in your browser using HTTPS, the browser will refuse to load any resources over HTTP. As you've tried, changing the API URL to have HTTPS instead of HTTP typically resolves this issue. However, your API must not allow for HTTPS connections. Because of this, you must either force HTTP on the main page or request that they allow HTTPS connections.

Note on this: The request will still work if you go to the API URL instead of attempting to load it with AJAX. This is because the browser is not loading a resource from within a secured page, instead it's loading an insecure page and it's accepting that. In order for it to be available through AJAX, though, the protocols should match.

Answer

I resolved this by adding following code to the HTML page, since we are using the third party API which is not controlled by us.

<meta http-equiv="Content-Security-Policy" content="upgrade-insecure-requests"> 

Hope this would help, and for a record as well.

If you are just visiting a webpage that you trust and you want to move forward fast, just:

1- Click the shield icon in the far right of the address bar.

Allow mixed content in Google Chrome

2- In the pop-up window, click "Load anyway" or "Load unsafe script" (depending on your Chrome version).


If you want to set your Chrome browser to ALWAYS(in all webpages) allow mixed content:

1- In an open Chrome browser, press Ctrl+Shift+Q on your keyboard to force close Chrome. Chrome must be fully closed before the next steps.

2- Right-click the Google Chrome desktop icon (or Start Menu link). Select Properties.

3- At the end of the existing information in the Target field, add: " --allow-running-insecure-content" (There is a space before the first dash.)

4- Click OK.

5- Open Chrome and try to launch the content that was blocked earlier. It should work now.

Answer

The reason for this error is very simple. Your AJAX is trying to call over HTTP whereas your server is running over HTTPS, so your server is denying calling your AJAX. This can be fixed by adding the following line inside the head tag of your main HTML file:

<meta http-equiv="Content-Security-Policy" content="upgrade-insecure-requests"> 
Answer

If your API code is running on a node.js server then you need to focus your attention there, not in Apache or NGINX. Mikel is right, changing the API URL to HTTPS is the answer but if your API is calling a node.js server, it better be set up for HTTPS! And of course, the node.js server can be on any unused port, it doesn't have to be port 443.

Instead of using Ajax Post method, you can use dynamic form along with element. It will works even page is loaded in SSL and submitted source is non SSL.

You need to set value value of element of form.

Actually new dynamic form will open as non SSL mode in separate tab of Browser when target attribute has set '_blank'

var f = document.createElement('form');
f.action='http://XX.XXX.XX.XX/vicidial/non_agent_api.php';
f.method='POST';
//f.target='_blank';
//f.enctype="multipart/form-data"

var k=document.createElement('input');
k.type='hidden';k.name='CustomerID';
k.value='7299';
f.appendChild(k);



//var z=document.getElementById("FileNameId")
//z.setAttribute("name", "IDProof");
//z.setAttribute("id", "IDProof");
//f.appendChild(z);

document.body.appendChild(f);
f.submit()

I was same problem, but for me the problem was ng build command. I was doing "ng build --prod" i have corrected it to "ng build --prod --base-href /applicationname/". and this solved my problem.

Answer

in my case, my localhost was http and my deployed version was https, so i used this script to add http-equiv meta tag only for https:

if (window.location.protocol.indexOf('https') == 0){
  var el = document.createElement('meta')
  el.setAttribute('http-equiv', 'Content-Security-Policy')
  el.setAttribute('content', 'upgrade-insecure-requests')
  document.head.append(el)
}
