Asking for Help: Processing POST enctype="multipart/form-data", libapreq2 /mod_upload examples cannot find

[巍才凌 <lingforrest@xxxxxxxxxxxxxxxxxxxxxx>]

Hi experts: 

I am developing a http mod_example for my web application. I want to proecess html form with POST enctype="multipart/form-data", for uploading files to my server. I google searched, did not find any API for POST "multipart/form-data" processing, like ap_parse_form_data for default POST processing. 

I find libapreq2 may help, but I cannot find an example at https://httpd.apache.org/apreq/docs/libapreq2/index.html   . I also searched for a mod_upload, my mod_example cannot call mod_upload_form defined in mod_upload. I didnot find an example of mod_upload.

Can any experts help to advise any examples for processing POST in type "multipart/form-data"?  

Thanks,

Forrest
