推荐答案

错误502Bad Gateway是内部服务器错误并且通常与您的代码无关，但与Web服务器和数据库系统之间的内部通信或类似。



与托管人员的Web服务器通信：他们也许可以对它进行排序。

Error 502 "Bad Gateway" is an internal server error and generally has nothing to do with your code, but with internal communications between the web server and the database system or similar.

Talk to your web server hosting people: they may be able to sort it.
