Solve the problem of 404 Not Found error in nginx accessing dynamic interface

Problem description

We design a set of recruitment back transfer system, and use ant design Vue and jfinal framework at the front and back end respectively. You want to deploy the project to the server, but external access always reports 404 not found

Solutions

The error is: the dynamic interface can not be found, but I don’t know whether there is a problem in the project or after nginx agent.
Therefore, it is necessary to test the interface of the project itself and the interface after nginx proxy.

First, test the interface in the project

Enter the command: curl on the Ubuntu side http://localhost :port/xxx/xxx

Here my interface is. curl http://localhost:20294/sys/login

Results of operation:

It shows that there is no problem with the interface in my project.

Test the interface after nginx proxy again

Then input the command in Ubuntu

curl http://localhost:8080/api/user/login

Running result:

the prompt here is that the interface cannot be found, which indicates that the problem lies in the proxy server nginx, so we need to modify the configuration file of nginx.

According to the suggestions of other blogs, I added a slash to this place in nginx configuration

after restarting the server, it still can’t work.

Complete solution

When I didn’t know what to do, I suddenly found that there were two nginx in my server ····
I was wondering if it was because there were two nginx, and the modified configuration file was not the nginx I started. So I replaced all nginx configuration files with my original configuration files, and then restarted. Still not

Worried about the two nginxs, I deleted all nginxs in the server. Delete steps (run the following steps in turn:

ps aux|grep nginx  #View nginx processes
kill -9 process number #Kill the nginx queried in the previous step (process number is in the second column)
find/-name nginx #Find the nginx file address
rm -rf xxx #Delete all nginx files

Finally, use weget to install the new nginx, and then install it according to the original installation steps. After modifying the configuration file, run curl to access the dynamic interface. All of a sudden, it’s OK!

The following is my nginx configuration file:

user root;
#user  nobody;
worker_processes  4;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

        }
    }
}

note: when configuring the dynamic access API, remember to add a slash at the end

So far, the problem has been solved perfectly.
