2. Check the code below
<?php
namespace api\rests\check_status;
use Yii;
use yii\web\HttpException;
use yii\base\Exception;
use yii\data\ActiveDataProvider;
use yii\data\DataFilter;
class IndexAction extends \yii\rest\IndexAction
{
/**
* @return int|string|ActiveDataProvider|DataFilter|null
*/
public function run()
{
try {
Yii::$app->db->open();
if (!Yii::$app->redis->ping()){
throw new HttpException(500, 'Redis is unavailable.');
} elseif (!Yii::$app->db->getIsActive()){
throw new HttpException(500, 'Database is unavailable.');
} else {
return 200;
}
} catch (Exception $e) {
$res = Yii::$app->response;
$res->statusCode = 500;
return $e->getMessage();
}
}
}
3. Print out $E->GetMessage(), which contains garbled characters. as shown in Figure 1
Figure 1
SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed: ��֪��������������
4. Edit the code, MB_CONvert_encoding — Convert the encoding of characters. The response status code is: 500, and the response body is: “SQLState[HY000][2002]php_network_getaddresses: getaddrinfo failed: I don’t know about such a host. “. As shown in Figure 2
![编辑代码，mb_convert_encoding — 转换字符的编码。响应状态码为：500，响应体为："SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed: 不知道这样的主机。 "。](https://www.shuijingwanwq.com/wp-content/uploads/2021/04/2.jpg)
Figure 2
<?php
namespace api\rests\check_status;
use Yii;
use yii\web\HttpException;
use yii\base\Exception;
use yii\data\ActiveDataProvider;
use yii\data\DataFilter;
class IndexAction extends \yii\rest\IndexAction
{
/**
* @return array|false|int|string|string[]|ActiveDataProvider|DataFilter|null
*/
public function run()
{
try {
Yii::$app->db->open();
if (!Yii::$app->redis->ping()){
throw new HttpException(500, 'Redis is unavailable.');
} elseif (!Yii::$app->db->getIsActive()){
throw new HttpException(500, 'Database is unavailable.');
} else {
return 200;
}
} catch (Exception $e) {
Yii::$app->response->statusCode = 500;
$message = mb_convert_encoding($e->getMessage(), "UTF-8", ["UTF-8", "GBK", "GB2312", "BIG5"]);
return $message;
}
}
}
5. Preliminary speculation, I don’t know that such a host is returned by the Windows 10 system. It has nothing to do with whether it is Chinese, but has a relationship with the coding of Chinese itself. Because the message is: “failed to open redis DB connection (tcp://localhost:63799, database=57): 10061 – Because the target computer actively refuses to connect.\r\n”, the encoding of unconverted characters can also run normally.
