bug: path parameter matching

[GongchuangSu]

When setting the route as "/api/:upload_id/info", the following request cannot be matched
/api/DCAppFile_2~9lwcn8WIw6sqq2v_Z7Wd6kLIfAhKVb0-MRKUYR2WMJKUUVTZKVLXOZKVLBXE65SOG5IUW52IOAZEE6JRNRIHEUSNOYXWI3RTJFLXEZKPJ5KU2VKIPBCHK3JUPJIUOTJSMJZECR2RPJVG643JM5YFEZLHON4XIU3Y-6XBBIO35THB6WGDDKZ63LJTWX2LVPM42PPC6RNJUNDNZB6J422ADLEQ6DVXSR2FBCWUX2TCYZASWQNRXFJ5O63KHLBHHEOEK-AES_256_ECB-1c3b94db/info
How should this be handled?

I ran the following test case and it passed (resty-radixtree matches it correctly), which suggests the issue is not related to lua-resty-radixtree. Could you provide additional details? Examples:

• how are you testing that route;
• which version are you using (of apisix and lua-resty-radixtree);
• what is the route configuration;
• access/error logs;
