为什么我有很多对 API 的请求，需要在 next.js 13v 的服务器端获取数据

我使用 Next.js 13v 在服务器端获取数据。我的组件 const 页脚 = async () => { // 获取数据 const allCategories = (await getAllCategories({})).data; 返回我使用 Next.js 13v 在服务器端获取数据。我的组件 const Footer = async () => { // Get data const allCategories = (await getAllCategories({})).data; return <footer className={styles.footer}></footer>; }; 我的功能 export const getAllCategories = async ( params: IGetAllCategoriesRequest, ): Promise<AxiosResponse<IGetAllCategoriesResponse>> => { const url = 'static-pages/category/public'; const response = await axiosInstance.get<IGetAllCategoriesResponse>( url, { params: params, }, ); return response; }; 如果请求成功，我有一个请求但是如果出现错误，我有很多请求，然后重定向到错误页面本机获取具有相同的行为那么为什么我在 next.js 13v 中对 API 有很多请求并在服务器端获取数据？可能和开发模式有关。我发现这篇文章可能与此行为有关：https://dev.to/noclat/fixing-too-many-connections-errors-with-database-clients-stacking-in-dev-mode-with-next -js-3kpm

Python 3.7 BeautifullSoup soup.find 错误 - find() 不接受关键字参数

我从 URL 获得了以下 HTML：我从 URL 中获得了以下 HTML： <h4> \r\n \r\n\r\n <a href="/l"> \r\n \r\n <span class="brandWrapTitle">\r\n <span class="productdescriptionbrand">Mxxx</span>\r\n </span>\r\n <span class="nameWrapTitle">\r\n <span class="productdescriptionname">Axxxname</span>\r\n </span>\r\n \r\n </a> \r\n\r\n </h4> 我正在尝试使用 python 来查找类名： import urllib.request from bs4 import BeautifulSoup url = "https://link" user_agent = 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/35.0.1916.47 Safari/537.36' urlwithagent = urllib.request.Request(url,headers={'User-Agent': user_agent}) response = urllib.request.urlopen(urlwithagent) soup = response.read() product = soup.find("h4", attrs ={"class=": "productdescriptionname"}) print (product) Everythink 完美运行直到上线： product = soup.find("h4", attrs ={"class=": "productdescriptionname"}) 我收到如下错误： find() takes no keyword arguments 我不知道如何解决它 - 有很多信息，但没有任何作用：/ 在使用 BeautifulSoup 之前，您需要将其转换为 find 对象，否则它会使用 str.find 例如： soup = BeautifulSoup(response.read(), "html.parser") product = soup.find("h4", attrs ={"class": "productdescriptionname"}) print (product) 我认为这值得一提，如果 find 方法有问题，检查 type(soup) 是一个很好的方法来查明您是否正在使用正确的 bs4.BeautifulSoup 对象而不是 str。我想在这里指出一件事，如果使用 soup.prettify() 使 html 可读。需要注意的是，.prettify() 将 bs4.BeautifulSoup 转换为 str。所以这应该单独使用，例如： soup = BeautifulSoup(response) # type(soup) --> bs4.BeautifulSoup print(soup.prettify()) # print readable html 不喜欢： soup = BeautifulSoup(response).prettify() # type(soup) --> str 我在网上读到的关于这个问题的另一件事是这样的：“你的 beautiful soup 版本可能不支持 find。”因此，我最终升级和降级了版本很多次，然后才意识到这是一个错误的陈述由业余爱好者制作。在打印之前我已经为此奋斗了大约 45 分钟type(soup)。我希望这可以节省其他人的时间。 Может кому подойдет история такая повторял за автором ютуба и переписывал код для парсинга и вышла такая же ошибка как в вопросе искал читал, шерстил инет пока не начал перепроверять свой код в общем мой код с ошибкой: from requests import Session from bs4 import BeautifulSoup as BS from time import sleep headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/118.0.0.0 YaBrowser/23.11.0.0 Safari/537.36'} work = Session() work.get('https://quotes.toscrape.com/', headers=headers) response = work.get('https://quotes.toscrape.com/login', headers=headers) soup = BS(response.text, 'lxml') token = soup.find('from').find('input').get('') в чем здесь ошибка？ вот в этой строке token = soup.find('from').find('input').get('') а именно soup.find('from') я решил скать ошибку методом исключения поэтому довел до такого состояния и понял что в странице нет тэга '来自' а есть тэг '形式' как только поменял на тэг 'form' ошибка с soup.find() - find() ушла может кому поможет

在 Rails 5 中单击浏览器上的后退按钮时，带有 Select2 的表单会重复

您收到异常是因为您尚未定义所需的权限如果应用程序开发后安装了播放服务，可能会发生 com.google.android.c2dm.permission.RECEIVE 权限已被授予但 android 仍在抱怨同样的错误。在这种情况下，您必须完全重新安装开发的应用程序才能使此权限发挥作用。我认为你必须检查 Kotlin 版本兼容性。
