專利數據的印度專利網站搜索

Question

我想寫一個Indian patent search website的網頁掃描器來獲取有關專利的數據。這是我迄今爲止的代碼。

#import the necessary modules 
import urllib2 
#import the beautifulsoup functions to parse the data 
from bs4 import BeautifulSoup 

#mention the website that you are trying to scrape 
patentsite="http://ipindiaservices.gov.in/publicsearch/" 

#Query the website and return the html to the variable 'page' 
page = urllib2.urlopen(patentsite) 

#Parse the html in the 'page' variable, and store it in Beautiful Soup format 
soup = BeautifulSoup(page) 

print soup 

不幸的是，印度專利網站不健全或我不知道如何進一步在這方面進一步。

這是上述代碼的輸出。

我想說的是，假設我提供了一個公司名稱，刮板應該獲得該公司的所有專利。如果我能夠正確地掌握這部分內容，我想做其他事情，比如提供一組刮刮器用來尋找專利的輸入。但是我陷入了我無法進一步發展的部分。

任何關於如何獲得這些數據的指針將不勝感激。

只需要請求即可。該職位是http://ipindiaservices.gov.in/publicsearch/resources/webservices/search.php一個PARAMRC_這是我們與了time.time創建一個時間戳。

在"field[]"每個值應該匹配到每個"fieldvalue[]"和反過來匹配"operator[]"是否選擇*AND**OR*或*NOT*，即我們傳遞值（S）陣列，每個密鑰指定後[]，沒有，沒有什麼會的工作：

data = { 
    "publication_type_published": "on", 
    "publication_type_granted": "on", 
    "fieldDate": "APD", 
    "datefieldfrom": "19120101", 
    "datefieldto": "20160906", 
    "operatordate": " AND ", 
    "field[]": ["PA"], # claims,.description, patent-number codes go here 
    "fieldvalue[]": ["chris*"], # matching values for ^^ go here 
    "operator[]": [" AND "], # matching sql logic for ^^ goes here 
    "page": "1", # gives you next page results 
    "start": "0", # not sure what effect this actually has. 
    "limit": "25"} # not sure how this relates as len(r.json()[u'record']) stays 25 regardless 

import requests 
from time import time 

post = "http://ipindiaservices.gov.in/publicsearch/resources/webservices/search.php?_dc={}".format(
    str(time()).replace(".", "")) 

with requests.Session() as s: 
    s.get("http://ipindiaservices.gov.in/publicsearch/") 
    s.headers.update({"X-Requested-With": "XMLHttpRequest"}) 
    r = s.post(post, data=data) 
    print(r.json()) 

輸出將看起來像下面，我不能添加這一切因爲有太多的數據要發佈：

{u'success': True, u'record': [{u'Publication_Status': u'Published', u'appDate': u'2016/06/16', u'pubDate': u'2016/08/31', u'title': u'ACTUATOR FOR DEPLOYABLE IMPLANT', u'sourceID': u'inpat', u'abstract': u'\n Systems and methods are provided for usin............. 

如果使用記錄鍵你喜歡類型的字典列表：

{u'Publication_Status': u'Published', u'appDate': u'2015/01/27', u'pubDate': u'2015/06/26', u'title': u'CORRUGATED PALLET', u'sourceID': u'inpat', u'abstract': u'\n A corrugated paperboard pallet is produced from two flat blanks which comprise a pallet top and a pallet bottom. The two blanks are each folded to produce only two parallel vertically extending double thickness ribs three horizontal panels two vertical side walls and two horizontal flaps. The ribs of the pallet top and pallet bottom lock each other from opening in the center of the pallet by intersecting perpendicularly with notches in the ribs. The horizontal flaps lock the ribs from opening at the edges of the pallet by intersecting perpendicularly with notches and the vertical sidewalls include vertical flaps that open inward defining fork passages whereby the vertical flaps lock said horizontal flaps from opening.\n ', u'Assignee': u'OLVEY Douglas A., SKETO James L., GUMBERT Sean G., DANKO Joseph J., GABRYS Christopher W., ', u'field_of_invention': u'FI10', u'publication_no': u'26/2015', u'patent_no': u'', u'application_no': u'642/DELNP/2015', u'UCID': u'WVJ4NVVIYzFLcUQvVnJsZGczcVRmSS96Vkh3NWsrS1h3Qk43S2xHczJ2WT0%3D', u'Publication_Type': u'A'} 

這是你的專利信息。

你可以看到，如果我們選擇在我們的瀏覽器中的幾個值，在值的所有fieldValue方法，場和操作排隊，AND是默認的，所以你看到，每個選項：

所以找出代碼，選擇你想要的東西和職務。
