How to prevent customer/section/load ajax call when ever i'm making my custom ajax call in M2?

Question

For my custom module i'm making a ajax call. during this ajax call a additional call ../customer/section/load/?sections=messages&update_section_id=true&_=1485355389960 getting triggered. Not sure this is called every time.

Anybody having idea over here?

Answer 1

the sections are part of the magento2 fpc hole punching mechanism.

It's a way of storing private customer data in the local storage and updating it on specific actions.

The mechanism is explained in the dev docs here: http://devdocs.magento.com/guides/v2.0/config-guide/cache/cache-priv-priv.html

all sections in the customerData, which are defined in any Vendor/Module/etc/frontend/sections.xml File will be updated on POST or PUT requests on the defined actions

The messages section is a special case, since it's updated on any action: https://github.com/magento/magento2/blob/2.1/app/code/Magento/Theme/etc/frontend/sections.xml#L10

I think this is just a default to enable any ajax call to add messages to the page.

This js component triggers the ajax call in this component: https://github.com/magento/magento2/blob/b1e56ed3b6f13f1ab780d8eddc33fc04cb6ecf75/app/code/Magento/Customer/view/frontend/web/js/section-config.js

You could try to override the section config for '*' by adding a module with a etc/frontend/sections.xml with the following content

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Customer:etc/sections.xsd">
    <action name="*">
    </action>
</config>

But, honestly, I think it will get merged and the original config will still be present. (Also the messages update trigger would be disabled for any action)

It should stop triggering, if you change your ajax call to a GET request (although this does not seem to be a 'nice' solution)

you could write a plugin on the \Magento\Customer\Block\SectionConfig class and just remove the messages section from your ajax call action I think

I had same problem and solution is very simple. Set the global event false in your jQuery request. Magento will not be able to intercept your request in that case.

example:

$.ajax({
    url: webUrl,
    type: 'POST',
    dataType: 'json',
    global: false,
    contentType: "application/json; charset=utf-8",
    data: myJSON,
    success: function (data) {

      }
});

Can you please elaborate more, customer/section/load json data is still displaying by trying the above solutions.
