SUPEE 6788修补程序Magento之后无法发送标题错误

Question

I'm using a template on my Magento 1.9.1.0 and after patch with SUPEE 6788, I'm getting the following errors in my system.log:

2016-04-26T00:50:23+00:00 DEBUG (7): Cannot send headers; headers already sent in /usr/share/nginx/html/app/code/community/Ves/Tabs/controllers/IndexController.php, line 140
2016-04-26T00:50:23+00:00 DEBUG (7): HEADERS ALREADY SENT: <pre>[0] /usr/share/nginx/html/app/code/core/Mage/Core/Controller/Response/Http.php:52

[5] /usr/share/nginx/html/app/Mage.php:684
[6] /usr/share/nginx/html/index.php:87

In IndexController.php on line 140, I have this code:

echo Mage::helper('core')->jsonEncode( $json );

I think the way as json is called is causing this errors. How can I fix this?

Thanks in advance.

Answer 1

What I understand from above question that you want to encode data and uses it somewhere in your program.

If the above is true then you can try the following solution.

 $this->getResponse()->clearHeaders()->setHeader('content-type', 'application/json', true); $this->getResponse()->setBody(json_encode($json)); 

Thanks
