python – 多POST查询(会话模式)

栏目: 编程工具 · 发布时间: 6年前

内容简介：http://stackoverflow.com/questions/35809428/multi-post-query-session-mode

我试图询问这个 site 以获得优惠清单.

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).

这到目前为止我所做的

首先我设置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优惠：

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,我收到一条消息,指示会话结束.非常感谢任何帮助,以解决这个.

更新添加Cookie：

我添加了cookie和中间GET,但我还没有任何结果.

library(httr)
first_url <- "https://compare.switchon.vic.gov.au/submit"
body <- list(energy_category="electricity",
             location="home",
             "location-home"="shift",
             "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)
使用具有以下数据的python requests.Session

对象到达结果页面：

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)

您应该在页面上看到的返回的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>您的电力供应</ 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)

下一个问题是实际数据是动态呈现的,您可以验证是否查看结果页面的来源,实际上可以以json格式获取所有提供程序：

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",
           data=form2)
    r = s.get("https://compare.switchon.vic.gov.au/service/offers")
    print(r.json())

然后,如果稍后再查看请求,例如当您单击结果页面上的比较选择按钮时,会出现以下请求：

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

所以你可以模仿通过使用关税或一些变化过滤的情况.

您可以将所有数据实际获取为json,如果在表单中输入与以下相同的值：

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"])

如果我们从总折扣价格中排除的列表中拉出前两个值：

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

你会得到：

  u'isClosed': False,
  u'offerDetails': [{u'basePrice': 980,
                     u'conditionalPrice': 980,

如果您点击https://compare.switchon.vic.gov.au/service/offers获取条目然后命中响应,则可以看到firebug控制台中返回的所有json：

python – 多POST查询(会话模式)

你应该可以拉出你想要的每个字段.

输出实际上有一些额外的结果,您在页面上看不到,除非您切换下面的tou按钮：

python – 多POST查询(会话模式)

您可以从结果中过滤这些内容,使其与默认输出完全匹配,或提供一个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)

如果您检查输出,您将在打开的结果中看到起始能量第三,价格为840,AGL关闭时为860,您可以将其应用于折扣输出：

python – 多POST查询(会话模式)

python – 多POST查询(会话模式)

如果您检查源代码,那么调用 排序 的两个js函数的定期输出似乎也由conditionalPrice排序：

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

所以现在应该肯定完全匹配网站输出.
