nginx reverse proxy not forwarding http requests?

Question

During the development stage, the front-end server is localhost:8080, and the back-end server is localhost:8088, which involves cross-domain, so nginx is used as a reverse proxy to convert all http requests starting with http://localhost:8080/api into http://localhost:8088/api, nginx configuration is as follows

The result is always 404

Use postman to test the backend interface and it shows normal

Check the task manager, nginx is running

nginx’s access log has no record, and there is no record in the error log. The following is the last content of the error log

I don’t know what went wrong

Answer 1

One missing /api

According to the request of the subject
Need to put http://localhost:8080/api => http://localhost:8088/api

But

location ^~ /api/ {
    proxy_pass http://localhost:8088/;
    ...
}

The implementation is http://localhost:8080/api => http://localhost:8088/http://localhost:8080/api => http://localhost:8088/
所以需要访问 http://localhost:8080/api/apiSo you need to access http://localhost :8080/api/api to access the real endpoint.
Change to

location ^~ /api/ {
    proxy_pass http://localhost:8088/api;
    ...
}

That’s it

Answer 2

Isn’t your server_name 127.0.0.1?
localhost不一定就代表127.0.0.1right?
