新手，在网上找了一个爬取淘宝数据的 然后就报错了...

dwn6905 发表于 2024-3-30 13:48

xpath表达式有问题吧，可以用浏览器开发者工具copy full xpath

selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"xpath","selector":"//a[@class="sn-login"]"}

"//a[@class="sn-login"]"
没有找到这个元素，先把这个改一下

改成 //*[@id="J_SiteNavLogin"]/div/div/a   试试

您好 感谢您的讲解 更换代码后还是相同的报错 可以跳转页面到淘宝扫码登录 但后面就直接关闭浏览器报错了 报错结果也是和之前一样

您好 抱歉我是小白 不太理解您说的 我该如何进行替换或者操作 谢谢

dwn6905 发表于 2024-3-30 15:44

按F12打开开发者工具，或通过在页面上右键，最下面有个检查，点击也能打开。
然后找到左上角一个鼠标样式的按钮。这个可以通过点击真实页面的元素，快速定位到它在网页源码中的位置。
https://attach.52pojie.cn//forum/202403/30/153742psqippqeornbbru4.png?l
选中元素后，开发者工具会高亮显示选中的元素，你可以再看看你需要的具体到哪个标签，然后按下图操作
https://attach.52pojie.cn//forum/202403/30/153744e1lhk5r5lrtlturr.png?l
另外还有一点就是，双引号里嵌套使用双引号的话需要转义字符，你可以单引号嵌套双引号或者双引号嵌套单引号，在你这里作用是一样的。

您好 我是想爬取淘宝某个商品链接里面的 名字 SKU规格（商品分类）和对应的价格 这种有没有简单方法来实现 或者说您知道有这种教学帖子吗

我看你爬虫逻辑写得没啥问题。我这边网有点卡，会响应超时程序光报错。我给你的代码加了几行代码，主要是获取Chrome对象时加了几个参数，让浏览器在程序结束不会自动关闭啥的，方便你调试。
```python

import openpyxl
import requests
from jsonpath import jsonpath
from selenium.webdriver import Chrome # 导入Chrome包
from selenium.webdriver.common.by import By

然后，我上面回复你的`copy full XPath`可以看看，我改完登录就没问题了，就是登录完，有点卡，网页没加载完，程序等不到就报错了。

我觉得你应该可以写出来的，只爬这些数据的话，很简单的。

您好 感谢您的讲解 更换代码后还是相同的报错 可以跳转页面到淘宝扫码登录 但后面就直接关闭浏览器报错了 ...

以跳转页面到淘宝扫码登录 但后面就直接关闭浏览器报错
是可以扫码，然后才关闭报错，还是还没有出现扫码页面

查看完整版本: python报错请求 麻烦帮忙看看
