如果将json_encode应用于输出，则不会显示异常消息 [英] Exception message not being shown if json_encode is applied to the output

问题描述

这是代码:

try{
//The exception is thrown.
throw new Exception('Parâmetros de consulta inválidos');

// and in the catch block it's caught successfully:
}catch(Exception $e){
    echo $e->getMessage(); //This prints the message correctly.

    $output = json_encode(array('msg'=>$e->getMessage()));
    echo $output; //But this fails...displays {"msg":null}

}

这是什么问题?

推荐答案

问题在于字符â和á.实际上，如果将它们替换为简单的a，您将获得正确的消息.

The problem is with the character â and á. Infact, if you replace them with a simple a, you'll get the right message.

替换此行:

array('msg'=>$e->getMessage())

与此:

array('msg'=>utf8_encode($e->getMessage()))

您必须进行此更改，因为json_encode可与ut8一起使用，因为您可以阅读这里.

You have to do this change because the json_encode works with ut8 as you can read here.
