基於PHP、Python 開發Alfred workflow 工具

1、實現的功能

• 1、快速生成 某文件中某接口的鏈路日誌 查詢語句
  • 效果 ：
• 2、時間戳轉換
  • 效果 ：
    

2、原理

• 根據輸入的條件，生成符合條件的列表

輸出的格式：
{
    "items": [
        {
            "title": "trace go_mutual_apply ",
            "subtitle": "grep `tail -1000 *go_mutual_apply*.log_json.20200512 |grep * | tail -1 |jq \".spanid\" ` *20200512",
            "arg": "grep `tail -1000 *go_mutual_apply*.log_json.20200512 |grep * | tail -1 |jq \".spanid\" ` *20200512",
            "icon": "icon.png"
        }
    ]
}

3、腳本：快速生成 某文件中某接口的鏈路日誌 查詢語句

• 創建腳本
  

• 輸入內容
  

• 腳本內容

    private $queryReg;

    public function __construct($query, $defaultResult = [])
    {
        $this->setQuery($query);

                    continue;
                }
                $this->defaultResult[] = [

        $this->defaultResult[] = $item;
    }

    public function result()
    {
        $newResult = [];
        if (!empty($this->query)) {
            foreach ($this->defaultResult as $key => $value) {
                $contains  = strpos($value['title'], $this->query);
                $preExists = preg_match($this->queryReg, $value['title'], $match);
                if ($contains !== false || $preExists) {

        }
        return json_encode(['items' => $this->defaultResult], 320);
    }

    public function case($key)
    {
        return strpos($this->query, $key) !== false;
    }

    public function setQuery($query)
    {
        //
        $this->query    = $query;
        $query          = str_replace(" ", ".*", $query);

        $result->createItem("trace $file ", 'grep `tail -1000 *' . $file . '*.log_json.' . $today . ' |grep ' . $url . ' | tail -1 |jq ".spanid" ` *' . $today . '');
    }
}


echo $result->result();

• 生成的列表 選中後複製到剪切板
  
  

4、Py腳本：時間戳轉換

# encoding: utf-8
import sys
import time
import json


def parse(strs):
    res = {"title": strs, "subtitle": "Copy to clipboard", "arg": strs, "icon": "icon.png"}
    return {"items": [res]}


def timestamp(param):
    strs = str(param).strip()
    if (strs == None or strs == ""):
        return int(time.time())
    elif strs.isdigit():  # 判斷是數字就轉成時間
        # 轉換成localtime
        time_local = time.localtime(float(strs))
        # 轉換成新的時間格式(2017-09-16 11:28:54)
        dtime = time.strftime("%Y-%m-%d %H:%M:%S", time_local)
        return dtime
    else:  # 判斷是字符串就轉成時間戳
        # 轉換成時間數組
        try:
            timeArray = time.strptime(strs, "%Y-%m-%d %H:%M:%S")
        except ValueError:
            timeArray = time.strptime(strs, "%Y-%m-%d")

        # 轉換成時間戳
        timestamp = int(time.mktime(timeArray))
        return timestamp


if __name__ == '__main__':
    if len(sys.argv) > 1:
        query = sys.argv[1]
        if len(sys.argv) > 2:
            query = query + " " + sys.argv[2]
    else:
        query = ''
    # query='{query}'
    strs = timestamp(query)
    #
    print(json.dumps(parse(strs)))
