1、在 Yii 2.0 中无响应，进而导致在浏览器中重复请求了 2 次。第 1 次无响应，第 2 次报错(程序禁止重复请求)。如图1
2、查看第 1 次请求的详细信息，在 标头 – 常规中，无响应状态码。如图2
3、查看第 1 次请求的详细信息，在 响应 中，无法加载响应数据。如图3
4、查看 Log Messages，在 E:\wwwroot\channel-pub-api\common\services\WeiboWeiboConnectWebAppAccessTokenService.php:92 处就停止往下执行了，实则应该继续执行才是。如图4
5、查看代码，第 92 行：$weiboWeiboConnectWebAppUserAccessToken->save()
public function saveModel($data)
{
/* 基于微博的微连接的网页应用的用户ID查找状态为启用的单个资源 */ $weiboWeiboConnectWebAppUserAccessToken = WeiboWeiboConnectWebAppUserAccessToken::find()->where(['weibo_weibo_connect_web_app_user_id' => $data['weiboWeiboConnectWebAppUserId']])->isDeletedNo()->enabled()->one();
if (!isset($weiboWeiboConnectWebAppUserAccessToken)) {
$weiboWeiboConnectWebAppUserAccessToken = new WeiboWeiboConnectWebAppUserAccessToken();
}
// 设置访问令牌的有效截止时间
$time = time();
$accessTokenExpireAt = $time + $data['expires_in'] + Yii::$app->params['weiboAuth']['weiboConnectWebApp']['authPeriod'] - Yii::$app->params['refreshToken']['timeOut'];
$weiboWeiboConnectWebAppUserAccessToken->attributes = [
'weibo_weibo_connect_web_app_id' => $data['weiboWeiboConnectWebAppId'],
'channel_app_source_id' => $data['channelAppSourceId'],
'channel_app_source_uuid' => $data['channelAppSourceUuid'],
'weibo_weibo_connect_web_app_user_id' => $data['weiboWeiboConnectWebAppUserId'],
'weibo_weibo_connect_web_app_user_uuid' => $data['weiboWeiboConnectWebAppUserUuid'],
'grant_type' => $data['grantType'],
'access_token' => $data['access_token'],
'expires_in' => $data['expires_in'],
'expires_at' => $accessTokenExpireAt,
'scope' => isset($data['scope']) ? $data['scope'] : '',
'user_id' => $data['uid'],
'status' => WeiboWeiboConnectWebAppUserAccessToken::STATUS_ENABLED,
];
if ($weiboWeiboConnectWebAppUserAccessToken->save()) {
return ['status' => true, 'data' => ['channel_app_source_uuid' => $data['channelAppSourceUuid']]];
} elseif ($weiboWeiboConnectWebAppUserAccessToken->hasErrors()) {
$firstError = '';
foreach ($weiboWeiboConnectWebAppUserAccessToken->getFirstErrors() as $message) {
$firstError = $message;
break;
}
return ['status' => false, 'code' => 214010, 'message' => Yii::t('error', Yii::t('error', Yii::t('error', '214010'), ['first_error' => $firstError]))];
} elseif (!$weiboWeiboConnectWebAppUserAccessToken->hasErrors()) {
throw new ServerErrorHttpException('Failed to insert/update the object (microblogging micro-connected web application user\'s access token) for unknown reason.');
}
}
6、在第 92 行之前打印对象：$weiboWeiboConnectWebAppUserAccessToken。打印结果如下。且第 1 次请求响应 200。如图5
common\logics\WeiboWeiboConnectWebAppUserAccessToken Object
(
[_attributes:yii\db\BaseActiveRecord:private] => Array
(
[weibo_weibo_connect_web_app_id] => 1
[channel_app_source_id] => 39
[channel_app_source_uuid] => c28915a6a8cb11ebba6254ee75d2ebc1
[weibo_weibo_connect_web_app_user_id] => 6
[weibo_weibo_connect_web_app_user_uuid] => c28a3efea8cb11ebb69354ee75d2ebc1
[grant_type] => authorization_code
[access_token] => 2.00bAKoqCV9i7fEee243e798c0zzui2
[expires_in] => 2626935
[expires_at] => 1622394001
[scope] =>
[user_id] => 2612590013
[status] => 1
)
)
7、编辑代码，第 92 行：$weiboWeiboConnectWebAppUserAccessToken->save(false)，保存记录之前不做验证(数据是可信任的)，以避免验证时间过长，进而导致响应时间过长，进而浏览器重复请求的情况。注：此前，此模型为 Redis AR 模型，后来调整为 MySQL AR 模型。在浏览器查看其时长为：2.57 秒。如图6、图7
public function saveModel($data)
{
/* 基于微博的微连接的网页应用的用户ID查找状态为启用的单个资源 */ $weiboWeiboConnectWebAppUserAccessToken = WeiboWeiboConnectWebAppUserAccessToken::find()->where(['weibo_weibo_connect_web_app_user_id' => $data['weiboWeiboConnectWebAppUserId']])->isDeletedNo()->enabled()->one();
if (!isset($weiboWeiboConnectWebAppUserAccessToken)) {
$weiboWeiboConnectWebAppUserAccessToken = new WeiboWeiboConnectWebAppUserAccessToken();
}
// 设置访问令牌的有效截止时间
$time = time();
$accessTokenExpireAt = $time + $data['expires_in'] + Yii::$app->params['weiboAuth']['weiboConnectWebApp']['authPeriod'] - Yii::$app->params['refreshToken']['timeOut'];
$weiboWeiboConnectWebAppUserAccessToken->attributes = [
'weibo_weibo_connect_web_app_id' => $data['weiboWeiboConnectWebAppId'],
'channel_app_source_id' => $data['channelAppSourceId'],
'channel_app_source_uuid' => $data['channelAppSourceUuid'],
'weibo_weibo_connect_web_app_user_id' => $data['weiboWeiboConnectWebAppUserId'],
'weibo_weibo_connect_web_app_user_uuid' => $data['weiboWeiboConnectWebAppUserUuid'],
'grant_type' => $data['grantType'],
'access_token' => $data['access_token'],
'expires_in' => $data['expires_in'],
'expires_at' => $accessTokenExpireAt,
'scope' => isset($data['scope']) ? $data['scope'] : '',
'user_id' => $data['uid'],
'status' => WeiboWeiboConnectWebAppUserAccessToken::STATUS_ENABLED,
];
if ($weiboWeiboConnectWebAppUserAccessToken->save(false)) {
return ['status' => true, 'data' => ['channel_app_source_uuid' => $data['channelAppSourceUuid']]];
} elseif ($weiboWeiboConnectWebAppUserAccessToken->hasErrors()) {
$firstError = '';
foreach ($weiboWeiboConnectWebAppUserAccessToken->getFirstErrors() as $message) {
$firstError = $message;
break;
}
return ['status' => false, 'code' => 214010, 'message' => Yii::t('error', Yii::t('error', Yii::t('error', '214010'), ['first_error' => $firstError]))];
} elseif (!$weiboWeiboConnectWebAppUserAccessToken->hasErrors()) {
throw new ServerErrorHttpException('Failed to insert/update the object (microblogging micro-connected web application user\'s access token) for unknown reason.');
}
}
8、查看重复请求 2 次时的第 1 次请求的响应时间长度，皆在 2500 ms 以上。如图8
9、还原代码，第 92 行：$weiboWeiboConnectWebAppUserAccessToken->save()。当环境设置为：Production 时，也不会响应时间过长。在浏览器查看其时长为：1.56 秒。由此得出结论：验证与否固然会影响响应时长，但是其根本还是在于环境设置(Development)所导致。如图9
