Cors in Ajax Meet 302 Redirect



I have a front-end server with port 8081
a background server with port 8080(Spring MVC + shiro)



When I send a request to 8080 , I have to set the cors headers on 8080



if the request is a simply request which only returns some json datas, it works



But When the response status is 302, Chrome shows 'Redirect from 'http://localhost:8080/' to 'http://localhost:8080/' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.'



I thought there are two reasons to occur this problem:



① if I intercept this 302 status, and deal this response.headers.Location,
I will solve this. But I can't intercept this response(with axios)



② Maybe some settings is wrong with 8080 server, when 302 occurs, the serve haven't set the cors Headers for this page. But I don't understand the backend code.



So, ① is feasible? or I need to change the settings on 8080 server?

Makefile test if variable is not empty

Makefile test if variable is not empty In a makefile I'm trying to I've created this simplified makefile to demonstrate my problem. Neither make a or make b executes the body of the if, I don't understand why not. make a make b .PHONY: a b a: $(eval MY_VAR = $(shell echo whatever)) @echo MY_VAR is $(MY_VAR) $(info $(MY_VAR)) ifneq ($(strip $(MY_VAR)),) @echo "should be executed" endif @echo done b: $(eval MY_VAR = $(shell echo '')) @echo MY_VAR is $(MY_VAR) $(info $(MY_VAR)) ifneq ($(strip $(MY_VAR)),) @echo "should not be executed" endif @echo done I'm using $ make --version GNU Make 3.81 There are several problems, and misunderstandings. Your MY_VAR is a make variable, set it without a <tab> to its value, and no need to $(eval ...) . MY_VAR:=$(shell echo whatever) is enough. No <tab> before $(info ...) neither, this is make – Zelnes ...
