在Python使用scraparazzie尋找新聞並透過LINE Notify發送

當初做scraparazzie這個套件的目的，是希望可以抓自己有興趣的topic和keywords的新聞傳送到某個IM的bot，就能根據之後自己再設定隨時看到新聞，方便自己炒股和追蹤農業災害新聞（啊…因為想要炒commodity嘛🤫）。但我並不需要內文，只需要標題、新聞來源和發布時間就好，有興趣再click連結去看。偶然看到LINE Notify的教學，就拿來實作一下吧。

開發環境：Python 3.7

另外也需要LINE Notify的權杖，因此會需要有LINE帳號。接下來先step-by-step介紹申請LINE Notify權杖的部分。

STEP 1:

至 https://notify-bot.line.me/zh_TW/ 進行登入
點選右上方帳號名稱選單中的「個人頁面」（My page）

點選【發行權杖】（Generate token）

輸入自訂「權杖名稱」, 這邊設定的名稱會在出現在提醒訊息的Title
選擇第一個【透過1對1聊天接受LINE Notify的通知】（1-on-1 chat with LINE Notify），然後按下「發行」（Generate token）

按下「發行」後，就會顯示權杖。請將權杖內容「複製」並記下來！程式與LINE Notify溝通就是靠這個權杖！

LINE Notify設定的部分大概到這裡結束。

STEP 2:

建立 lineNotifyMessage.py 檔案
在token部分，記得將剛剛在LINE Notify記下的權杖貼上去

from scraparazzie import scraparazzie
import requests
import time
from random import randrange

# LINE Notify的部分｜LINE Notify setting

token = "paste_your_token_here"    # 從LINE Notify獲得的權杖｜Token from LINE Notify
def lineNotifyMessage(token, msg):    # LINE Notify傳訊息的設定｜Message sending setting of LINE Notify
    headers = {
        "Authorization": "Bearer " + token, 
        "Content-Type" : "application/x-www-form-urlencoded"
    }

    payload = {'message': msg}
    r = requests.post("https://notify-api.line.me/api/notify", headers = headers, params = payload)
    return r.status_code

# 設定你想發的訊息或東西的部分｜Setting the items or message you want to send
keywords = ["locust infest plague", "Chinese medicine"]
locations = ["Canada"]
chooen_language = ["English"]

def searching_topic(locations, keywords, languages):
    for location in locations:
        location = "{}".format(location)
        for topic in keywords:
            items = "{}".format(topic)
            for language in languages:
                language = "{}".format(language)
                print("Items in progress: " + location + " - " + topic + " - " + language)
                client = scraparazzie.NewsClient(language = language, location = location, query = items, max_results = 1) # 利用scraparazie尋找詢問的關鍵字｜Searching the keywords through scraparazzie
                client.print_news()
                output = client.export_news() # 輸出結果｜Output searching result
                for export_items in output:
                    message = "\n" + "處理關鍵字｜Processing keywords: " + items + "\n" + "標題｜Title: " + export_items['title'] + "\n" + "新聞來源｜Source: " + export_items['source'] + "\n" + "連結｜Link: " + export_items['link'] + "\n" + "發布時間｜Publish date: " + export_items['publish_date']
                    lineNotifyMessage(token, message) # 運行lineNotifyMessage()｜Run lineNotifyMessage()
                sleep_time = randrange (1, 10)
                time.sleep(sleep_time)
