證書驗證失敗（_ssl.c：645）>」一個particuar域

Question

這一個特定域的每個請求現在在證書驗證失敗（_ssl.c：645）結束>

我不知道是什麼造成這種情況。自昨晚試圖弄清楚如何解決問題以來，我一直在尋找答案，但不知怎的，我無法讓它運行。

我試過pip卸載-y certifi & & pip install certifi == 2015.04.28但它沒有幫助。

這裏是我的代碼：

def trade_spider(max_pages): 
page = -1 

partner_ID = 2 
location_ID = 25 


already_printed = set() 

for page in range(0,20): 
    response = urllib.request.urlopen("http://www.getyourguide.de/s/search.json?q=" + str(Region) +"&page=" + str(page)) 
    jsondata = json.loads(response.read().decode("utf-8")) 
    format = (jsondata['activities']) 
    g_data = format.strip("'<>()[]\"` ").replace('\'', '\"') 
    soup = BeautifulSoup(g_data) 



    hallo = soup.find_all("article", {"class": "activity-card activity-card-horizontal "}) 


    for item in hallo: 
     headers = item.find_all("h3", {"class": "activity-card-title"}) 
     for header in headers: 
      header_final = header.text.strip() 
      if header_final not in already_printed: 
       already_printed.add(header_final) 



     prices = item.find_all("span", {"class": "price"}) 
     for price in prices: 
      #itemStr += ("\t" + price.text.strip().replace(",","")[2:]) 
      price_final = price.text.strip().replace(",","")[2:] 
      #if itemStr2 not in already_printed: 
      #print(itemStr2) 
       #already_printed.add(itemStr2) 


     deeplinks = item.find_all("a", {"class": "activity-card-link"}) 
     for t in set(t.get("href") for t in deeplinks): 
      #itemStr += "\t" + t 
      deeplink_final = t 
      if deeplink_final not in already_printed: 
       #print(itemStr3) 
       already_printed.add(deeplink_final) 

     Language = "Deutsch" 

     end_final = "Header: " + header_final + " | " + "Price: " + str(price_final) + " | " + "Deeplink: " + deeplink_final + " | " + "PartnerID: " + str(partner_ID) + " | " + "LocationID: " + str(location_ID)+ " | " + "Language: " + Language 
     if end_final not in already_printed: 
      print(end_final) 
      already_printed.add(end_final)

燦有人幫助我？任何反饋aprreciated :)

我會通過檢查的OpenSSL能驗證證書的進一步調查：
