Vue The cross domain exception of the provider is as follows ：

1.F12 see Network Whether there are multiple request headers （ If there are more than one There will be the above problem ）

2. resolvent ：

Check nginx To configure Is there more than one

Just remove it and leave one （ Leave code or nginx Any of them will do ）

add_header Access-control-Allow-Origin *;
