下面来分享一个配置文件实例：


server {
## 禁SQL注入 Block SQL injections
set $block_sql_injections 0;
if ($query_string ~ “union.*select.*(“) {
set $block_sql_injections 1;
}
if ($query_string ~ “union.*all.*select.*”) {
set $block_sql_injections 1;
}
if ($query_string ~ “concat.*(“) {
set $block_sql_injections 1;
}
if ($block_sql_injections = 1) {
return 444;
}
## 禁掉文件注入
set $block_file_injections 0;
if ($query_string ~ “[a-zA-Z0-9_]=http://”) {
set $block_file_injections 1;
}
if ($query_string ~ “[a-zA-Z0-9_]=(..//"WebBench") {

  }
