why nginx echo module echo doesn't echo anything

vidy.videni

I add this location below to nginx config file , reload it , and curl "http://localhost/echo" .it returns 404 Not Found. any reason ? I recompile this module to nginx twice, so I don't think something wrong with compilation, and their versions match. any help will be appreciated.

location /echo {

echo The current request uri is $request_uri;

echo hello;

echo world;

echo_flush;

}

The corresponding error log is :

2014/09/23 11:09:14 [error] 6580#0: *337 open() "/var/www/echo" failed (2: No such file or directory), client: 127.0.0.1, server: idp.local, request: "GET /echo HTTP/1.1", host: "idp.local"

I am wondering why request /echo, nginx tries to open /var/www/echo ?

Your other regex locations in the same nginx.conf might have
overridden this "location /echo" (because regex locations takes
priority over prefix locations). Try adding "=" to make your location
the top priority (the exact location):

    location = /echo {
        ...
    }

I did this , it turned out to be that it failed to kill all nginx processes ,using the command sudo killall nginx in my Mac, I thought the command works, but it didn't. after I restart nginx completely, it is ok now. still thanks，

From the error log message, nginx is definitely using some other
location (you have defined in the same nginx.conf) to serve this /echo
request.
