我为什么不能在“请求”中循环通过“有效载荷”来迭代我的网页抓取?

摘要:我想遍历请求有效负载,以便可以更改每个刮板的登录ID号.

我正在使用请求&美丽的汤做网刮.
要登录该页面,我需要输入唯一的ID号;我有一个这样的数字列表,称为hit_list.

对于任何给定的ID号,此脚本都可以正常工作.但是我想做的是自动化它,使其贯穿我的整个hit_list

换句话说,我希望payload_1中的num每次迭代都更改.目前num保持不变,并且抓取只是根据hit_list的长度进行迭代(即,在这种情况下,相同的抓取将运行五次)

请注意,我对编码非常陌生,这是我的第一个项目.我知道它可能存在问题,很高兴收到建设性的批评.

您需要为每个帖子获取新的__EVENTVALIDATION令牌等,您不能仅从浏览器中复制值并将其硬编码到帖子数据中:

def renew(s):
    soup = BeautifulSoup(s.get(url).content,"html.parser.)
    return {"__VIEWSTATE": soup.select_one("#__VIEWSTATE")["value"],

这为您提供了表格栏中BER证书号的所有信息,您已经有了BER证书号,因此您无需担心.

如您所知,您只需要将数据从第一篇文章返回的内容传递到第二个有效内容,如果将逻辑封装在函数中,这也将使您的代码更易于管理:

def renew(soup):
    return {"__VIEWSTATE": soup.select_one("#__VIEWSTATE")["value"],
            "__VIEWSTATEGENERATOR": soup.select_one("#__VIEWSTATEGENERATOR")["value"],
            "__EVENTVALIDATION": soup.select_one("#__EVENTVALIDATION")["value"]}


def parse_data(soup):
    address = soup.select_one("#ctl00_DefaultContent_BERSearch_dfBER_div_PublishingAddress").text.strip()
    MPRN = soup.select_one("#ctl00_DefaultContent_BERSearch_dfBER_container_MPRN div.formControlReadonly").text.strip()
    emissions_indicator, emissions_indicator_unit = soup.select_one(
        "#ctl00_DefaultContent_BERSearch_dfBER_div_CDERValue").text.split()
    emissions_indicator_unit = emissions_indicator_unit.strip("()")
    BER_score, BER_actual_rating, BER_unit = soup.select_one(
        "#ctl00_DefaultContent_BERSearch_dfBER_div_EnergyRating").text.split()
    BER_unit = BER_unit.strip("()")
    return {"MPRN": MPRN, "emissions_indicator": emissions_indicator,
            "emissions_indicator_unit": emissions_indicator_unit,
            "BER_score": BER_score, "BER_actual_rating": BER_actual_rating,
            "BER_unit": BER_unit, "address": address}

def submint_to_db(dct):
    with connection.cursor() as cursor:
        print('SUCCESSFUL CONNECTION')
        sql = "INSERT INTO table1 ( %s ) VALUES ( %s )" % (",".join(dct),  ', '.join(['%s'] * len(dct)))
        cursor.execute(sql, dct.values())

payload_1 = {
    'ctl00$DefaultContent$BERSearch$dfSearch$Bottomsearch': 'Search'}
payload_2 = {
    '__EVENTTARGET': 'ctl00$DefaultContent$BERSearch$gridRatings$gridview$ctl02$ViewDetails',
}

with requests.session() as s:
    tokens = renew(BeautifulSoup(requests.get(url).content, "html.parser"))
    for num in hit_list:
        # update the post data with new token values
        payload_1['ctl00$DefaultContent$BERSearch$dfSearch$txtBERNumber'] = num
        payload_1.update(tokens)
        r = s.post(url, data=payload_1)
        tokens2 = renew(BeautifulSoup(r.content, 'html.parser'))
        payload_2.update(tokens2)
        soup = BeautifulSoup(requests.post(url, data=payload_2).content, "html.parser")
        submint_to_db(parse_data(soup))

我没有解析所有数据,但是其余部分的逻辑是相同的,打印返回解析结果的字典将为您提供:
