Node_报:Error [ERR_HTTP_HEADERS_SENT]: Cannot set headers after they are sent to the client

遇到情况:

我在Node js中设置了res.setHeader(\'Content-type\',\'text/html;charset=utf-8\');

导致这个错误

翻译:

Error [ERR_HTTP_HEADERS_SENT]: Cannot set headers after they are sent to the client

 Error [ERR_HTTP_HEADERS_SENT]:无法在发送到客户端后设置标头

 

解决办法:

把这句代码删掉 问题得到了解决
