再回顧自己昨天作的

做得很好

0840

再來是 #include <json-c/json.h>

#include <stdio.h>
#include <cgi.h>
#include <json-c/json.h>

#define STRCMP(a,b) (strcmp(a,b) == 0)

s_cgi *cgi;

int main(void) {
    char info[256];
    json_object *obj = json_object_new_object();

    cgi = cgiInit();
    cgiSetType("application/json");
    cgiHeader();

    char *act = cgiGetValue(cgi, "act");
    if (!act) {
        json_object_object_add(obj, "fail", json_object_new_boolean(TRUE));
        sprintf(info, "act needed");
        json_object_object_add(obj, "info", json_object_new_string(info));
        goto end;
    }

    if (STRCMP(act, "hello")) {
        json_object_object_add(obj, "ok", json_object_new_boolean(TRUE));
        sprintf(info, "hi, %s develpment team, nice to meet you.", "579X");
        json_object_object_add(obj, "info", json_object_new_string(info));
        goto end;
    }

    json_object_object_add(obj, "fail", json_object_new_boolean(TRUE));
    sprintf(info, "unknown act: %s", act);
    json_object_object_add(obj, "info", json_object_new_string(info));

end:
    printf("%s", json_object_to_json_string(obj));
    json_object_put(obj);
//    cgiFree (cgi);

    return 0;
}

一樣是不要去呼叫 cgiFree()

需要告知 mips-openwrt-linux-gcc 四件事

-I/home/jeffrey/openwrt/staging_dir/target-mips_34kc_uClibc-0.9.33.2/usr/include/
-L/home/jeffrey/openwrt/staging_dir/target-mips_34kc_uClibc-0.9.33.2/usr/lib/
-lcgi
-ljson-c

command 如下

mips-openwrt-linux-uclibc-gcc -I/home/jeffrey/openwrt/staging_dir/target-mips_34kc_uClibc-0.9.33.2/usr/include/ -L/home/jeffrey/openwrt/staging_dir/target-mips_34kc_uClibc-0.9.33.2/usr/lib/ -lcgi -ljson-c -o event.cgi main.c

網址列輸入 http://192.168.1.251/cgi-bin/event.cgi?act=hello

出現熟悉的畫面 { "ok": true, "info": "hi, IoT Platform development team, nice to meet you." }

太感動了

0910

試著 implement 自己定義的 control center 的 event

POST /event
- 何時使用
  - Control Box 平常用來更新自己的 Things 狀態給 Control Center 的時候
  - Control Box 有緊急或重要的事情要告訴 Control Center 的時候
- 那些 event 可以用
  - normal event
  - emergency event
  - important event
  - critical evane
- 內容(JSON 格式)
  - box - Control Box 的名子
  - location - Control Box 所在的位置
  - thing - thing 的名子
  - type - 是什麼 event
    - normal
    - important
    - emergency
    - critical
  - info - 具體的內容
    - 不同的 thing 有不同的內容格式

0945

看來真的進入我的專業領域了
掌握度非常好

#include <stdio.h>
#include <cgi.h>
#include <json-c/json.h>

#define STRCMP(a,b) (strcmp(a,b) == 0)

    printf("%s", json_object_to_json_string(obj));
    json_object_put(obj);
    exit(0);
}

static void _ok(void) {
    json_object_object_add(obj, "ok", json_object_new_boolean(TRUE));
    printf("%s", json_object_to_json_string(obj));
    json_object_put(obj);
    exit(0);
}


static void _event_normal(void) {
    char *_info = cgiGetValue(cgi, "info");
    if (!_info) _fail("info needed");

    json_object *info = json_tokener_parse(_info);
    if (info == NULL) _fail("json_tokener_parse(info) fail");

    json_object_object_add(obj, "type", json_object_new_string("critical"));

    json_object_object_add(obj, "info", info);
    _ok();
}


int main(void) {

    cgi = cgiInit();
    cgiSetType("application/json");
    cgiHeader();

    obj = json_object_new_object();

    char *box = cgiGetValue(cgi, "box");
    if (!box) _fail("box needed");

    char *location = cgiGetValue(cgi, "location");
    if (!location) _fail("location needed");

    char *thing = cgiGetValue(cgi, "thing");
    if (!thing) _fail("thing needed");

    char *type = cgiGetValue(cgi, "type");
    if (!type) _fail("type needed");

    if (STRCMP(type, "normal"))     _event_normal();
    if (STRCMP(type, "important"))  _event_important();
    if (STRCMP(type, "emergency"))  _event_emergency();
    if (STRCMP(type, "critical"))   _event_critical();

    char info[256];
    sprintf(info, "unknown event type: %s", type);
    _fail(info);

}

就這樣的 event.cgi 已經可以做測試了

禮拜二早上
關心一下 Lun 的狀況
Lun 將他的 source code - 一隻 c code 壓縮打包
上傳到 mantis wiki 上去

我很快就會面臨 source code commit 的問題了
這最好在禮拜四開會的時候討論

1015

做測試吧

先照著這一篇玩玩看

JMeter 入門

很棒的軟體呢! 真方便

要技壓群雄就要把這一套玩熟才行

browser 不會有回應

這三個 event.cgi process 卡死了

有點懷疑是 cgiFree 的問題

寫一隻沒有用到 cgi library 的 cgi 來測試

main_0.c

#include <stdio.h>

int main(void) {
    printf("Content-Type: text/html\n\n");
    printf("<h1>Hello World</h1>\n");
    return 0;
}

怎麼用呢?

Beginner’s Guide

The way nginx and its modules work is determined in the configuration file. By default, the configuration file is named nginx.conf and placed in the directory /usr/local/nginx/conf, /etc/nginx, or /usr/local/etc/nginx.

JS9331 是在 /etc/nginx

處長找我跟 Jammy 開會
其實是針對我的 mail 啦

10 分鐘解決
我告知了 openWrt 原生的 uhttpd 一秒鐘 22 個 POST 以上就掛了
我目前再試 nginx

反正禮拜四就看數據吧

透過處長的談話我得到的情報有

他不知道我的 IoT Platform 會不會用到 openHAB
他沒有認真看我的 mantis wiki
他只是看到二月底的 schedule 會飄掉所以來關心
他覺得自己給的效能建議很讚
他不知道怎麼測效能
他不知道 CoAP 和 MQTT
他只在乎如果用到 open source, 那授權是啥

Google nginx fastcgi c

這會得到一些我目前需要的

nginx 難搞阿
