 魔力赏市集搜索?使用python去以一个合适的价格搜到想要的手商品_哔哩哔哩_bilibili

写给自己看的,不回答问题

改进:

1. 添加了筛选词 exclude_words

2. 避免重复打印相同条目

3. 添加打印循环次数,让你知道程序还在跑(2023.12.20优化了显示效果,实现了直接刷新)

4. 简化打印,只打印id,名称,价格

5. 优化异常捕捉,跑太多会触发哔哩哔哩安全风控策略

6. 请gpt用Thread加速,不知道有没有用

  1. 获取heder(手动)

        进入网址https://mall.bilibili.com/neul-next/index.html?page=magic-market_index​

        选择“网络”,此时会发现是空白的,点击刷新,才会刷新出信息

选择“Fetch/XHR”,右键list

选择复制cURL(bash)

转到postman(获取你的header)(自动?)

在My Workspace里点击加号

https://mall.bilibili.com/mall-magic-c/internet/c2c/v2/list

粘贴刚才复制的cURL(bash),(好像直接复制上面这句即可)点击Send

选择Python-request,复制postman提供的代码,你就知道自己的header

代码

以下代码不能直接运行,你要填充自己的header

from time import sleep
import requests
import json
from concurrent.futures import ThreadPoolExecutor
import sys


def fetch_data(payload, headers):
        response = requests.post(url, headers=headers, data=payload)
        response.raise_for_status()
        return response.json()


def process_item(item):
    c2c_items_id = item["c2cItemsId"]
    c2c_items_name = item["c2cItemsName"]
    show_price = item["showPrice"]
    if c2c_items_id not in seen_c2c_items_ids:
        seen_c2c_items_ids.add(c2c_items_id)
        if not any(exclude_word in c2c_items_name for exclude_word in exclude_words):
            print(f"nid: {c2c_items_id}, 名称: {c2c_items_name}, 价格: {show_price}")

        try:

                if minutes % 1 == 0:
                    print(f"睡了{minutes}分钟")
                sleep(30)
                minutes += 0.5
        except requests.exceptions.JSONDecodeError:
            print("输入参数错误,看起来是触发了哔哩哔哩安全风控策略")
            break

        count += 1
        sys.stdout.write("r---{:03d}---".format(count))
        sys.stdout.flush()

print("==============获取完成================")
if not i_want:
    print("没有找到")
else:
    print("n找到期望商品:")
    print(i_want)
    cheap = min(i_want, key=lambda x: x["price"])
    print("n找到便宜好货:")
    print(cheap)

打印结果示例(现版本策略)

打印结果示例(旧版策略)

报错说明(一点点)

错误号:412 由于触发哔哩哔哩安全风控策略,该次访问请求被拒绝。

解决方法:

  • 使用魔法改变IP(缺点:可能网络不稳定,会导致报错)
  • 多sleep,比如每50次sleep30秒?不知道引发风控的点在哪里

获取到感兴趣的商品后

复制id,在网址的itemsId替换为复制的id即可https://mall.bilibili.com/neul-next/index.html?page=magic-market_detail&noTitleBar=1&itemsId=【你的id】&from=market_index
