Nginx URI参数%xx字符解码

Nginx URI参数%xx字符解码

对URI参数值中的%XX这样的编码序列进行解码，可以使用第三方 ngx_set_misc 模块提供的 set_unescape_uri 指令：

    location /decode {
        set_unescape_uri $name $arg_name;
        set_unescape_uri $class $arg_class;

        echo "name: $name";
        echo "class: $class";
    }

    location /test {
      echo "name: $arg_name";
      echo "class: $arg_class";
    }


$ curl 'http://localhost/test?name=hello%20xiemx&class=1'
name: hello%20xiemx
class: 1

$ curl 'http://localhost/decode?name=hello%20xiemx&class=1'
name: hello xiemx
class: 1
