How to send plain text response from Nginx

You can use a return statement in Nginx to send a plain text response.

In your Nginx server entry, add

location ~* "^/hello/(.*)" {
    default_type text/plain;
    return 200 "Hello $1\n";
}

Now you can access the page with the URL

boby@sok-01:~$ curl http://localhost/hello/World
Hello World
boby@sok-01:~$

Here is another example

location  "/hello" {
    default_type text/plain;
    return 200 "Hello World\n";
}

For any URL starting with /hello, you get the “Hello World” response.
