python解析谷歌在线表格链接,转化为数组形式,图片转化为链接

限于喜欢 提交于 2020-01-03 04:12:28
在线表格已成为趋势,传统的表格导入导出已经不能满足现在企业的发展。 必须支持在线表格的导入,只需要输入在线表格的链接,就能将数据读取出来。 而且相比相传表格,能够将图片信息一块读取。在线表格中的图片也是图片链接形式。 附上源码,这里我只打印了每一行数据的数组形式,大家根据各自需求复用代码。 import requests,random from bs4 import BeautifulSoup #获得静态的界面 def get_static_html(site_url): print('开始加载', site_url, '静态页面') headers_list = [ 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/67.0.3396.79 Safari/537.36', 'Mozilla/5.0 (Windows NT 6.1; WOW64; rv:34.0) Gecko/20100101 Firefox/34.0 ', 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/534.57.2 (KHTML, like Gecko) Version/5.1.7 Safari/534.57.2',

问题 I am using the following css on my meter-bars but somehow the styling does not work on safari (see below screenshots). I am pretty new to css and copied below css.

南笙酒味 提交于 2020-01-02 14:49:48
在上一小节中,我们已经提取到了房源的具体信息,这一节中,我们主要是对提取到的数据进行后续的处理,以及进行相关的设置。 数据处理 我们这里以把数据存储到mongo数据库为例。 编写pipelines.py文件 import pymongo class MongoPipeline(object): collection = 'lianjia_house' #数据库collection名称 def __init__(self, mongo_uri, mongo_db): self.mongo_uri = mongo_uri self.mongo_db = mongo_db @classmethod def from_crawler(cls,crawler): return cls( mongo_uri = crawler.settings.get('MONGO_URI'), mongo_db = crawler.settings.get('MONGO_DB') ) def open_spider(self,spider): self.client = pymongo.MongoClient(self.mongo_uri) self.db = self.client[self.mongo_db] def close(self, spider): self.client.close()

Consume WCF with JavaScript but keep it generic enough for all clients?

喜夏-厌秋 提交于 2020-01-01 07:25:05
问题 I want to create a web service for my clients so they can display their data on their own web sites. Since I will not know what platform each client is running, what would be the best solution to create a proxy to the WCF service that can be used by all browsers? Also, I am not sure how I should present the data. Let's assume my users do not have any development skills. I will, by some other interface, give the user the ability to download the code needed to create the request and then

Script stack space exhausted firefox

女生的网名这么多〃 提交于 2020-01-01 03:41:08
问题 I am working with a large XML response from a web service. When I try to get that using a URL, after some time it displays an error in Firebug that "script stack space quota is exhausted" How can i resolve that? 回答1: It sounds like there is some recursion going on when processing the xml, that is essentially causing a stack overflow (by any name). Thoughts: work with less data if you are processing the data manually, try to use less recursion? perhaps manual tail-call or queue/stack based

Stylesheet not loading in Mozilla Firefox

我的梦境 提交于 2019-12-30 09:49:07
问题 I'm stumped. Working on a site that isn't loading properly in FireFox. It loads great in Chrome and even IE, but for some reason the stylesheet isn't loading in FireFox. The site: http://gregsonaccounting.com I'm using html5 code and have used the basic resets and such from html5 Boiler Plate. Not sure if the problem is in my html or CSS. Any insight is extremely helpful. Many thanks. 回答1: Your problem comes from style.css which begins by @charset "IBM437" Replace it with @charset "UTF-8";

for of loop querySelectorAll

↘锁芯ラ 提交于 2019-12-28 20:41:41
问题 Mozilla states that "for of loops will loop over NodeList objects correctly". (source: https://developer.mozilla.org/en-US/docs/Web/API/NodeList) However, this doesn't work in Chrome 43. Is this incorrect documentation or a browser bug? The copied example code used on a page with checkboxes: var list = document.querySelectorAll( 'input[type=checkbox]' ); for (var item of list) { item.checked = true; } 回答1: Edit: This is shipping in Chrome 51. Jake Archibald posted a simple fix: NodeList
