Store View switcher not working on front-end and it throws an error

[latypatil]

If we select any store then site will go to that store and again we select another store then it throws an error because the url is wrong.

Preconditions

1. Magento ver. 2.2.0
2. PHP 7.0.24, mysql Ver 14.14

Steps to reproduce

1. Create different store view from admin panel and all will appear on front-end
2. Select any store view (No error)
3. Again select another store view(error will be there)

Expected result

1. It should show all store views without any error
   Ex. http://10.16.16.141/magento2.2/?___store=aus ==>this is for one of store view
   http://10.16.16.141/magento2.2/?___store=usa ==> This should be for different store view
   OR
   Base url should be the same for any store ,only store will get switch!

Actual result

1. [Screenshot, logs]
   

After changing the store view second time it redirect to below url :
http://10.16.16.141/magento2.2/?___store=aus?___store=usa

(URL is only for reference , it will not work)

@latypatil, thank you for your report.
We've created internal ticket(s) MAGETWO-80840 to track progress on the issue.

The issue is in /vendor/magento/module-store/Block/Switcher.php with function getTargetStorePostData () where $store->getCurrentUrl(false) , Current url has been passed there and It should be $this->getUrl('stores/store/switch').

this issue is a result of merge in issue [https://github.com//issues/8509] which fixes cookie redirect problems with multidomains

@latypatil, I think that this issue is similar to issue #10908? Do you have logs in var/logs/exception.log?

@latypatil, i had the same problem and was able to fix it with this small fix.

I know it's not perfect and that i should overwrite the core module in a custom plugin, but anyway i'll not need this fix anymore when i'll update the code with the new release containing the official fix.

In /vendor/magento/module-store/block/switcher.php, in getTargetStorePostData method, replace

return $this->_postDataHelper->getPostData( $store->getCurrentUrl(false), $data );

by:

$currentUrl = strtok($store->getCurrentUrl(false), '?'); return $this->_postDataHelper->getPostData( $currentUrl, $data );
