多POST查询(会话模式)
ags*_*udy 15 python session r scrapy httr
我正在尝试查询此网站以获取优惠列表.问题是我们需要在收到最终结果之前填写2个表单(2个POST查询).
这就是我到目前为止所做的:
首先,我在设置cookie后发送第一个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)
然后尝试使用第二个帖子查询检索商品:
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,我收到一条消息,表明会话结束.非常感谢您解决此问题的任何帮助.
更新添加cookie:
我添加了cookie和中间GET,但我仍然没有任何结果.
library(httr)
first_url <- "https://compare.switchon.vic.gov.au/submit"
body <- list(energy_category="electricity",
location="home",
"location-home"="shift",

qr<- POST(first_url,

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"

使用带有以下数据的python requests.Session对象进入结果页面:
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)
您应该h1在页面上看到的返回的html中看到匹配:
<h1>Your electricity offers</h1>
或使用scrapy表单请求:
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)
我们可以验证的是"<h1>Your electricity offers</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)

下一个问题是动态呈现的实际数据,您可以验证是否查看结果页面的来源,您实际上可以获得json格式的所有提供程序:
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",

r = s.get("https://compare.switchon.vic.gov.au/service/offers")
print(r.json())

然后,如果您稍后查看请求,例如当您单击结果页面上的比较选择按钮时,会出现如下请求:
https://compare.switchon.vic.gov.au/service/offer/tariff/9090/9092
因此,您可以通过使用关税或某些变体进行过滤来模仿所发生的情况.
如果在表单中输入与下面相同的值,您实际上可以将所有数据作为json获取:
form1 = {"energy_category": "electricity",
"location": "home",
"location-home": "shift",
"distributor": "7",
"postcode": "3000",
"energy_concession": "0",
"solar": "0",

}
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"}

js = s.get("https://compare.switchon.vic.gov.au/service/offers").json()["offersList"]
by_discount = sorted(js, key=lambda d: d["offerDetails"][0]["fullDiscountedPrice"])
如果我们只按总折扣价格从列表中提取前两个值:
from pprint import pprint as pp
pp(by_discount[:2])
你会得到:

如果单击https://compare.switchon.vic.gov.au/service/offersget条目然后点击r esponse,你可以看到在firebug控制台中返回的所有json :
您应该能够从中拉出您想要的每个字段.
输出实际上有一些额外的结果,除非你切换下面的tou按钮,否则你在页面上看不到它们:
您可以从结果中筛选这些内容,以便与默认输出完全匹配,或者提供包含辅助函数的选项:
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)
If you check the output you will see origin energy third with a price of 840 in the results with the switch on or 860 for AGL when it is off, you can apply the same to the discount output:
The regular output also seems to be ordered by conditionalPrice if you check the source the two js functions that get called for ordering are:
ng-click="changeSortingField('conditionalPrice')"
ng-click="changeSortingField('fullDiscountedPrice')"
So that should now definitely completely match the site output.
- 很好的答案!谢谢 !我会等待R答案,但我肯定会接受这个答案! (2认同)
- @agstudy,不用担心,我对R一点都不了解,所以我担心我不会在那个部门使用太多. (2认同)
