root
和 alias
location /images {
root /data/
}
访问此规则时会去你服务器的 /data/images
路径下查找资源
location /images {
alias /data/
}
访问此规则会去你服务器的 /data/
路径下查找资源
总结:root
拼接 alias
替换
匹配优先级
- =
- ^~
- ~
- /
由上向下优先级递减
反斜杠的理解
server {
listen 80;
server_name localhost;
location /api1/ {
proxy_pass http://localhost:8080;
}
# http://localhost/api1/xxx -> http://localhost:8080/api1/xxx
location /api2/ {
proxy_pass http://localhost:8080/;
}
# http://localhost/api2/xxx -> http://localhost:8080/xxx
location /api3 {
proxy_pass http://localhost:8080;
}
# http://localhost/api3/xxx -> http://localhost:8080/api3/xxx
location /api4 {
proxy_pass http://localhost:8080/;
}
# http://localhost/api4/xxx -> http://localhost:8080//xxx,请注意这里的双斜线,好好分析一下。
location /api5/ {
proxy_pass http://localhost:8080/haha;
}
# http://localhost/api5/xxx -> http://localhost:8080/hahaxxx,请注意这里的haha和xxx之间没有斜杠,分析一下原因。
location /api6/ {
proxy_pass http://localhost:8080/haha/;
}
# http://localhost/api6/xxx -> http://localhost:8080/haha/xxx
location /api7 {
proxy_pass http://localhost:8080/haha;
}
# http://localhost/api7/xxx -> http://localhost:8080/haha/xxx
location /api8 {
proxy_pass http://localhost:8080/haha/;
}
# http://localhost/api8/xxx -> http://localhost:8080/haha//xxx,请注意这里的双斜杠。
