我試圖詢問這個 ofollow,noindex" target="_blank">site 以獲得優惠清單.

問題是我們需要在收到最終結果之前填寫2個表單(2個POST查詢).

這到目前為止我所做的

首先我設定cookie後傳送第一個POST：

library(httr)
set_cookies(.cookies = c(a = "1", b = "2"))
first_url <- "https://compare.switchon.vic.gov.au/submit"
body <- list(energy_category="electricity",
location="home",
"location-home"="shift",
"retailer-company"="",
postcode="3000",
distributor=7,
zone=1,
energy_concession=0,
"file-provider"="",
solar=0,
solar_feedin_tariff="",
disclaimer_chkbox="disclaimer_selected")
qr<- POST(first_url,
encode="form",
body=body)

然後嘗試使用第二個帖子查詢檢索優惠：

gov_url <- "https://compare.switchon.vic.gov.au/energy_questionnaire/submit"
qr1<- POST(gov_url,
encode="form",
body=list(`person-count`=1,
`room-count`=1,
`refrigerator-count`=1,
`gas-type`=4,
`pool-heating`=0,
spaceheating="none",
spacecooling="none",
`cloth-dryer`=0,
waterheating="other"),
set_cookies(a = 1, b = 2))
)
library(XML)
dc <- htmlParse(qr1)

但不幸的是,我收到一條訊息,指示會話結束.非常感謝任何幫助,以解決這個.

更新新增Cookie：

我添加了cookie和中間GET,但我還沒有任何結果.

library(httr)
first_url <- "https://compare.switchon.vic.gov.au/submit"
body <- list(energy_category="electricity",
location="home",
"location-home"="shift",
"retailer-company"="",
postcode=3000,
distributor=7,
zone=1,
energy_concession=0,
"file-provider"="",
solar=0,
solar_feedin_tariff="",
disclaimer_chkbox="disclaimer_selected")
qr<- POST(first_url,
encode="form",
body=body,
config=set_cookies(a = 1, b = 2))

xx <- GET("https://compare.switchon.vic.gov.au/energy_questionnaire",config=set_cookies(a = 1, b = 2))

gov_url <- "https://compare.switchon.vic.gov.au/energy_questionnaire/submit"
qr1<- POST(gov_url,
encode="form",
body=list(
`person-count`=1,
`room-count`=1,
`refrigerator-count`=1,
`gas-type`=4,
`pool-heating`=0,
spaceheating="none",
spacecooling="none",
`cloth-dryer`=0,
waterheating="other"),
config=set_cookies(a = 1, b = 2))

library(XML)
dc <- htmlParse(qr1)

使用具有以下資料的python requests.Session

物件到達結果頁面：

form1 = {"energy_category": "electricity",
"location": "home",
"location-home": "shift",
"distributor": "7",
"postcode": "3000",
"energy_concession": "0",
"solar": "0",
"disclaimer_chkbox": "disclaimer_selected",
}


form2 = {"person-count":"1",
"room-count":"4",
"refrigerator-count":"0",
"gas-type":"3",
"pool-heating":"0",
"spaceheating[]":"none",
"spacecooling[]":"none",
"cloth-dryer":"0",
"waterheating[]":"other"}

sub_url = "https://compare.switchon.vic.gov.au/submit"

with requests.Session() as s:
s.post(sub_url, data=form1)
r = (s.get("https://compare.switchon.vic.gov.au/energy_questionnaire"))
s.post("https://compare.switchon.vic.gov.au/energy_questionnaire/submit",
data=form2)
r = s.get("https://compare.switchon.vic.gov.au/offers")
print(r.content)

您應該在頁面上看到的返回的html中看到匹配的h1：

<h1>Your electricity offers</h1>

或使用scrapy表單請求：

import scrapy

class Spider(scrapy.Spider):
name = 'comp'
start_urls = ['https://compare.switchon.vic.gov.au/energy_questionnaire/submit']

form1 = {"energy_category": "electricity",
"location": "home",
"location-home": "shift",
"distributor": "7",
"postcode": "3000",
"energy_concession": "0",
"solar": "0",
"disclaimer_chkbox": "disclaimer_selected",
}

sub_url = "https://compare.switchon.vic.gov.au/submit"
form2 = {"person-count":"1",
"room-count":"4",
"refrigerator-count":"0",
"gas-type":"3",
"pool-heating":"0",
"spaceheating[]":"none",
"spacecooling[]":"none",
"cloth-dryer":"0",
"waterheating[]":"other"}

def start_requests(self):
return [scrapy.FormRequest(
self.sub_url,
formdata=form1,
callback=self.parse
)]

def parse(self, response):
return scrapy.FormRequest.from_response(
response,
formdata=form2,
callback=self.after
)

def after(self, response):
print("<h1>Your electricity offers</h1>" in response.body)

我們可以驗證的是“<h1>您的電力供應</ h1>”：

2016-03-07 12:27:31 [scrapy] DEBUG: Crawled (200) <GET https://compare.switchon.vic.gov.au/offers#list/electricity> (referer: https://compare.switchon.vic.gov.au/energy_questionnaire)
True
2016-03-07 12:27:31 [scrapy] INFO: Closing spider (finished)

下一個問題是實際資料是動態呈現的,您可以驗證是否檢視結果頁面的來源,實際上可以以json格式獲取所有提供程式：

with requests.Session() as s:
s.post(sub_url, data=form1)
r = (s.get("https://compare.switchon.vic.gov.au/energy_questionnaire"))
s.post("https://compare.switchon.vic.gov.au/energy_questionnaire/submit",
data=form2)
r = s.get("https://compare.switchon.vic.gov.au/service/offers")
print(r.json())

然後,如果稍後再檢視請求,例如當您單擊結果頁面上的比較選擇按鈕時,會出現以下請求：

https://compare.switchon.vic.gov.au/service/offer/tariff/9090/9092

所以你可以模仿通過使用關稅或一些變化過濾的情況.

您可以將所有資料實際獲取為json,如果在表單中輸入與以下相同的值：

form1 = {"energy_category": "electricity",
"location": "home",
"location-home": "shift",
"distributor": "7",
"postcode": "3000",
"energy_concession": "0",
"solar": "0",
"disclaimer_chkbox": "disclaimer_selected"
}

form2 = {"person-count":"1",
"room-count":"1",
"refrigerator-count":"1",
"gas-type":"4",
"pool-heating":"0",
"spaceheating[]":"none",
"spacecooling[]":"none",
"cloth-dryer":"0",
"cloth-dryer-freq-weekday":"",
"waterheating[]":"other"}


import json
with requests.Session() as s:
s.post(sub_url, data=form1)
r = (s.get("https://compare.switchon.vic.gov.au/energy_questionnaire"))
s.post("https://compare.switchon.vic.gov.au/energy_questionnaire/submit",
data=form2)
js = s.get("https://compare.switchon.vic.gov.au/service/offers").json()["offersList"]
by_discount = sorted(js, key=lambda d: d["offerDetails"][0]["fullDiscountedPrice"])

如果我們從總折扣價格中排除的列表中拉出前兩個值：

from pprint import pprint as pp
pp(by_discount[:2])

你會得到：

當您點選“折扣價格”過濾器按鈕時,應該與您在頁面上看到的內容相匹配.

對於正常的檢視,它似乎是由conditionalPrice或basePrice命令,再次拉兩個第一個值應該匹配你在網頁上看到的內容：

base = sorted(js, key=lambda d: d["offerDetails"][0]["conditionalPrice"])

如果您點選https://compare.switchon.vic.gov.au/service/offers獲取條目然後命中響應,則可以看到firebug控制檯中返回的所有json：

你應該可以拉出你想要的每個欄位.

輸出實際上有一些額外的結果,您在頁面上看不到,除非您切換下面的tou按鈕：

您可以從結果中過濾這些內容,使其與預設輸出完全匹配,或提供一個包含輔助函式的選項：

def order_by(l, k, is_tou=False):
if not is_tou:
filt = filter(lambda x: not x["offerDetails"][0]["isTouOffer"], l)
return sorted(filt, key=lambda d: d["offerDetails"][0][k])
return sorted(l, key=lambda d: d["offerDetails"][0][k])

import json
with requests.Session() as s:
s.post(sub_url, data=form1)
r = (s.get("https://compare.switchon.vic.gov.au/energy_questionnaire"))
s.post("https://compare.switchon.vic.gov.au/energy_questionnaire/submit",
data=form2)
js = s.get("https://compare.switchon.vic.gov.au/service/offers").json()["offersList"]
by_price = by_discount(js, "conditionalPrice", False)

print(by_price[:3)

如果您檢查輸出,您將在開啟的結果中看到起始能量第三,價格為840,AGL關閉時為860,您可以將其應用於折扣輸出：

如果您檢查原始碼,那麼呼叫排序的兩個js函式的定期輸出似乎也由conditionalPrice排序：

ng-click="changeSortingField('conditionalPrice')"
 ng-click="changeSortingField('fullDiscountedPrice')"

所以現在應該肯定完全匹配網站輸出.
