Webscraping: No any Data Shown in scrapy
Question:
I am trying to crawl this website but I am getting empty response
I am using scrapy and I tried printing xpath but I am getting empty array I though this was straight forward task but now I am unable to get data from the table.
here is my code.
import scrapy
from scrapy import Request
class ShareInfoSpider(scrapy.Spider):
name = 'share'
def start_requests(self):
url = "https://nepsealpha.com/investment-calandar/ipo"
yield Request(url, callback=self.parse)
def parse(self, response):
for tr in response.xpath("//table[@id='DataTables_Table_0']"):
print(tr)
Answers:
The data you see is requested from other URL via JavaScript, so you need other methods how to get the data. For example requests/json:
import json
import requests
import pandas as pd
params = {
"draw": "1",
"columns[0][data]": "symbol",
"columns[0][name]": "symbol",
"columns[0][searchable]": "true",
"columns[0][orderable]": "true",
"columns[0][search][value]": "",
"columns[0][search][regex]": "false",
"columns[1][data]": "units",
"columns[1][name]": "units",
"columns[1][searchable]": "true",
"columns[1][orderable]": "true",
"columns[1][search][value]": "",
"columns[1][search][regex]": "false",
"columns[2][data]": "opening_date",
"columns[2][name]": "opening_date",
"columns[2][searchable]": "true",
"columns[2][orderable]": "true",
"columns[2][search][value]": "",
"columns[2][search][regex]": "false",
"columns[3][data]": "closing_date",
"columns[3][name]": "closing_date",
"columns[3][searchable]": "true",
"columns[3][orderable]": "true",
"columns[3][search][value]": "",
"columns[3][search][regex]": "false",
"columns[4][data]": "issue_manager",
"columns[4][name]": "issue_manager",
"columns[4][searchable]": "true",
"columns[4][orderable]": "true",
"columns[4][search][value]": "",
"columns[4][search][regex]": "false",
"columns[5][data]": "status",
"columns[5][name]": "status",
"columns[5][searchable]": "true",
"columns[5][orderable]": "true",
"columns[5][search][value]": "",
"columns[5][search][regex]": "false",
"columns[6][data]": "view",
"columns[6][name]": "view",
"columns[6][searchable]": "true",
"columns[6][orderable]": "true",
"columns[6][search][value]": "",
"columns[6][search][regex]": "false",
"start": "0",
"length": "10",
"search[value]": "",
"search[regex]": "false",
}
api_url = "https://nepsealpha.com/investment-calandar/ipo"
headers = {"X-Requested-With": "XMLHttpRequest"}
data = requests.get(api_url, params=params, headers=headers).json()
# uncomment to print all data
# print(json.dumps(data, indent=4))
df = pd.DataFrame(data["data"])
print(df)
Prints:
