在webman中使用swoole一鍵協(xié)程化不生效

mysql:
SQLSTATE[HY000]: General error: 2014 Cannot execute queries while other unbuffered queries are active. Consider using PDOStatement::fetchAll(). Alternatively, if your code is only ever going to run against mysql, you may enable query buffering by setting the PDO::MYSQL_ATTR_USE_BUFFERED_QUERY attribute. (SQL: select CONNECTION_ID(),SLEEP(30);)

用 Channel 實(shí)現(xiàn)連接池。

這個(gè)報(bào)錯(cuò)說(shuō)明一鍵協(xié)程已經(jīng)生效了。
報(bào)錯(cuò)的意思是數(shù)據(jù)庫(kù)連接不能同時(shí)被多個(gè)協(xié)程使用,要么每個(gè)協(xié)程一個(gè)數(shù)據(jù)庫(kù)連接,要么使用連接池機(jī)制。
協(xié)程不是所有composer庫(kù)都支持,你要用協(xié)程就必須改造所有的第三方composer庫(kù),保證這些庫(kù)互斥使用某些資源,保證不會(huì)全局變量污染等等。
感謝你的回答!按swoole官網(wǎng)的文檔,一鍵協(xié)程化【https://wiki.swoole.com/#/runtime】 說(shuō)明,我以為可以不需要使用相關(guān)連接池。。。
如果是如你所說(shuō)的話,那我就必須要用連接池了,不然每個(gè)協(xié)程內(nèi)都實(shí)例化一個(gè)新的連接出來(lái),那連接數(shù)很快就會(huì)打滿
