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:

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

把这句代码删掉问题得到了解决
