我无法使用react,react-dom和react-router的服务器实现来访问DOM.我要么具有ReferenceError:未定义文档,要么浏览器历史记录需要DOM错误.
服务器条目:
module.exports = function( req, res, next ) {
match({ routes, location: req.url }, (error, redirectLocation, renderProps) => {
if (error) {
res
.status(500)
.send(error.message);
} else if (redirectLocation) {
res.redirect(302, redirectLocation.pathname + redirectLocation.search);
} else if (renderProps) {
res
.status( 200 )
.set( 'Content-Type', 'text/html' )
.send( '<!doctype html>' +
renderToString(
[ <RoutingContext {...renderProps} />,
<HtmlDocument /> ]
)
);
} else {
res
.status(404)
.send('Not found');
}
})
};
client.js:
import { render } from 'react-dom';
import …我无法使用BeautifulSoup避免最大递归深度Python RuntimeError.
我试图通过嵌套的代码部分进行递归并提取内容.美化的HTML看起来像这样(不要问为什么它看起来像这:)):
<div><code><code><code><code>Code in here</code></code></code></code></div>
我传递汤对象的功能是:
def _strip_descendent_code(self, soup):
sys.setrecursionlimit(2000)
# soup = BeautifulSoup(html, 'lxml')
for code in soup.findAll('code'):
s = ""
for c in code.descendents:
if not isinstance(c, NavigableString):
if c.name != code.name:
continue
elif c.name == code.name:
if isinstance(c, NavigableString):
s += str(c)
else:
continue
code.append(s)
return str(soup)
您可以看到我正在尝试增加默认的递归限制,但这不是一个解决方案.我已经增加到C达到计算机内存限制的程度,上面的功能永远不会起作用.
任何帮助让这个工作,并指出错误/ s将非常感激.
