開始來實作 session 的部分
1540
M300 上 HTTP 不同的 query 有不同的權限需求
可以參考原本 iweb 上的 _register_http_endpoint()
static void _register_http_endpoint(struct mg_connection *nc)
{
mg_register_http_endpoint(nc, "/api/login", _api_login);
mg_register_http_endpoint(nc, "/api/logout", _api_logout);
mg_register_http_endpoint(nc, "/api/whoAmI", _api_whoAmI);
mg_register_http_endpoint(nc, "/api/firmwareUpload", _api_firmwareUpload);
mg_register_http_endpoint(nc, "/api/configurationUpload", _api_configurationUpload);
mg_register_http_endpoint(nc, "/api/openvpnUpload", _api_openvpnUpload);
mg_register_http_endpoint(nc, "/api/ipsecUpload", _api_ipsecUpload);
mg_register_http_endpoint(nc, "/api/brandTopPngUpload", _api_brandTopPngUpload);
mg_register_http_endpoint(nc, "/api/customerFileUpload", _api_customerFileUpload);
#if !defined(PROSRC_NO_DIDO) && defined(PROSRC_DO_REMOTE)
mg_register_http_endpoint(nc, "/DO_ON", _api_do_on);
mg_register_http_endpoint(nc, "/DO_OFF", _api_do_off);
mg_register_http_endpoint(nc, "/DO_PULSE", _api_do_pulse);
mg_register_http_endpoint(nc, "/RESTORE_DO_ALARM", _api_restore_do_alarm);
#endif
// System / Time And Date
mg_register_http_endpoint(nc, "/cgi-bin/sntp.cgi?act=config", _handler_level_normal);
mg_register_http_endpoint(nc, "/cgi-bin/sntp.cgi?act=apply", _handler_level_admin);
// System / COM Ports
mg_register_http_endpoint(nc, "/cgi-bin/com.cgi?act=config", _handler_level_normal);
mg_register_http_endpoint(nc, "/cgi-bin/com.cgi?act=apply", _handler_level_admin);
mg_register_http_endpoint(nc, "/cgi-bin/vcom.cgi?act=config", _handler_level_normal);
mg_register_http_endpoint(nc, "/cgi-bin/vcom.cgi?act=apply", _handler_level_admin);
...
先專注在 System / Time And Date 的部分
// System / Time And Date
mg_register_http_endpoint(nc, "/cgi-bin/sntp.cgi?act=config", _handler_level_normal);
mg_register_http_endpoint(nc, "/cgi-bin/sntp.cgi?act=apply", _handler_level_admin);
之前是利用 mongoose 提供的 mg_register_http_endpoint() 把某個 uri_path 註冊到某個 handler
由於目前 iweb.fcgi 牽涉到 lighttpd 提供的 URL rewrite
以 sntp.cgi 為例
經過以下 lighttpd config 裡的 url rewrite 設定後
#### url handling modules (rewrite, redirect, access)
url.rewrite-once = (
"^/api/whoAmI$" => "/fcgi-bin/iweb.fcgi?app=api&act=whoAmI",
"^/cgi-bin/([a-zA-Z]+).cgi$" => "/fcgi-bin/iweb.fcgi?app=$1",
"^/cgi-bin/([a-zA-Z]+).cgi\?act=([a-zA-Z]+)$" => "/fcgi-bin/iweb.fcgi?app=$1&act=$2"
)
/cgi-bin/sntp.cgi?act=config 會轉成 /fcgi-bin/iweb.fcgi?app=sntp&act=config
這個轉換是為了相容於之前的 html 部分的 api
不過我們當然可以使用正確的 fastcgi url - /fcgi-bin/iweb.fcgi?app=sntp&act=config
我們來看一下這兩個 uri 產生的相關 HTTP env
/fcgi-bin/iweb.fcgi?app=sntp&act=config- QUERY_STRING: "app=sntp&act=config"
- REQUEST_URI: "/fcgi-bin/iweb.fcgi?app=sntp&act=config"
- SCRIPT_FILENAME: "/www/fcgi-bin/iweb.fcgi"
- SCRIPT_NAME: "/fcgi-bin/iweb.fcgi"
/cgi-bin/sntp.cgi?act=config- QUERY_STRING: "app=sntp&act=config"
- REQUEST_URI: "/cgi-bin/sntp.cgi?act=config"
- SCRIPT_FILENAME: "/www/fcgi-bin/iweb.fcgi"
- SCRIPT_NAME: "/fcgi-bin/iweb.fcgi"
我們若要在 iweb.fcgi 的程式裡做像 _register_http_endpoint() 的事情
像 sntp.cgi 我們就不應該用 /cgi-bin/sntp.cgi?act=config 來做註冊的動作
不然不須 url rewrite 的 /fcgi-bin/iweb.fcgi?app=sntp&act=config 一進來就會找不到對應的 handler 了
觀察 /fcgi-bin/iweb.fcgi?app=sntp&act=config 和 /cgi-bin/sntp.cgi?act=config 相關的 env 可以發現
兩者的 QUERY_STRING 都是 app=sntp&act=config
所以我們應該使用 app=sntp&act=config 來註冊相對應的 handler
這樣一來不管是 /fcgi-bin/iweb.fcgi?app=sntp&act=config 或 /cgi-bin/sntp.cgi?act=config 就都可以對應到相同的 handler 了
不過更好的處理方式是寫一個專門處理權限的程式
權限過了就呼叫該 rule 提供的 handler
這樣個別的 CGI 就不用去處理 session 以及 權限 的細節
這需要思考一下
也許也可以先寫醜醜的先求有
再來 refactoring
試著把今天作的整理一下做個 commit

porting /api/ahoAmI
- cgi - /api/whoAmI?uuid=xxx
- fcgi = /fcgi-bin/iweb.fcgi?app=api&act=whoAmI
use cgi_init_values() to get cookie into jweb.in.session;
then whoAmI() can according to this value to responce as previous iweb
