How to implement interception of URI in nginx location

illustrate:

Root and alias in location

The root directive simply sets the search root to the directory set by root, that is, it does not truncate the URI, but uses the original URI to jump to the directory to find the file
The aias directive will truncate the matching URI and then use the path set by alias plus the remaining URI as a subpath for searching

The uri of the proxy_pass in location

If the proxy_pass url does not contain uri

If the trailing character is "/", the matching URI will be truncated.
If the trailing character is not "/", the matching URI will not be truncated.

If the proxy_pass url has a uri, the matching uri will be truncated

Examples

Root in location

root@pts/1 $ ls -ld /data/web/lctest*|awk '{print $NF}'
/data/web/lctest
/data/web/lctest2
/data/web/lctest3
/data/web/lctest4


location /lctest {
  root /data/web/;
}

location /lctest2/ {
  root /data/web/;
}
location /lctest3 {
  root /data/web;
}
location /lctest4/ {
  root /data/web;
}

The curl test results are as follows

Note: If you don't add a / at the end when you enter it in the browser, it will be automatically added, but curl will not

root@pts/1 $ curl http://tapi.xxxx.com/lctest/
hello world

root@pts/1 $ curl http://tapi.xxxx.com/lctest2/
hello world
2

root@pts/1 $ curl http://tapi.xxxx.com/lctest3/
3
hello world

root@pts/1 $ curl http://tapi.xxxx.com/lctest4/
hello world
4

location alias

location /lctest5 {
  alias /data/web/;
}
location /lctest6/ {
  alias /data/web/;
}

location /lctest7 {
  alias /data/web;
}

## 403 /data/web forbidden
location /lctest8/ {
  alias /data/web;
}

The curl test results are as follows

curl 'http://tapi.kaishustory.com/lctest5/'
curl 'http://tapi.kaishustory.com/lctest6/'
curl 'http://tapi.kaishustory.com/lctest7/'
The results are all /data/web/index.html output root@pts/1 $ curl 'http://tapi.kaishustory.com/lctest8/'
<html>
<head><title>403 Forbidden</title></head>
<body bgcolor="white">
<center><h1>403 Forbidden</h1></center>
<hr><center>nginx</center>
</body>
</html>

location proxy_pass

#--------proxy_pass configuration---------------------
location /t1/ { proxy_pass http://servers; } #Normal, not truncated location /t2/ { proxy_pass http://servers/; } #Normal, truncation location /t3 { proxy_pass http://servers; } #Normal, not truncated location /t4 { proxy_pass http://servers/; } #Normal, truncation location /t5/ { proxy_pass http://servers/test/; } #Normal, truncation location /t6/ { proxy_pass http://servers/test; } #Missing "/", truncation location /t7 { proxy_pass http://servers/test/; } #Contains "//", truncation location /t8 { proxy_pass http://servers/test; } #Normal, truncation

Test Scripts

for i in $(seq 8)
do
  url=http://tapi.xxxx.com/t$i/doc/index.html
  echo "----------$url-----------"
  curl url
done
