Question

我想获取网页的所有文本，因此我正在尝试将html2text模块与urllib.request模块一起使用-

import urllib.request 
import html2text
request_url = urllib.request.urlopen('https://dev.to/justdevasur/let-s-perform-google-search-with-python-2gpi') 
u=request_url.read()
print(html2text.html2text(u))
print('Done')

但是我遇到了以下错误-

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Users\rauna\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.8_qbz5n2kfra8p0\LocalCache\local-packages\Python38\site-packages\html2text\__init__.py", line 947, in html2text
    return h.handle(html)
  File "C:\Users\rauna\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.8_qbz5n2kfra8p0\LocalCache\local-packages\Python38\site-packages\html2text\__init__.py", line 142, in handle
    self.feed(data)
  File "C:\Users\rauna\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.8_qbz5n2kfra8p0\LocalCache\local-packages\Python38\site-packages\html2text\__init__.py", line 138, in feed
    data = data.replace("</' + 'script>", "</ignore>")
TypeError: a bytes-like object is required, not 'str'

由于错误提示<property name="hibernate.use_identifier_rollback" value="true" />需要一个Exception in thread "main" java.lang.NullPointerException at org.hibernate.persister.entity.AbstractEntityPersister.resetIdentifier(AbstractEntityPersister.java:5362) at org.hibernate.event.internal.DefaultDeleteEventListener.onDelete(DefaultDeleteEventListener.java:164) at org.hibernate.event.internal.DefaultDeleteEventListener.onDelete(DefaultDeleteEventListener.java:72) at org.hibernate.event.service.internal.EventListenerGroupImpl.fireEventOnEachListener(EventListenerGroupImpl.java:110) at org.hibernate.internal.SessionImpl.fireDelete(SessionImpl.java:877) at org.hibernate.internal.SessionImpl.delete(SessionImpl.java:809) at org.hibernate.internal.SessionImpl.remove(SessionImpl.java:2714) at mock.Main.main(Main.java:20)对象，因此您应该这样做：

@Entity
public class Foo {
    @Id
    @GeneratedValue(strategy = GenerationType.SEQUENCE)
    private Long id;

    private String name;
    //...
}

但这不仅抛出html2text，而且似乎bytes-like与Python3不兼容。例如，请参见此question。

因此，我建议使用另一种方法，例如：

import urllib.request 
import html2text
request_url = urllib.request.urlopen('https://dev.to/justdevasur/let-s-perform-google-search-with-python-2gpi') 
print(html2text.html2text(request_url))
print('Done')

打印：403

与“ urllib.request”模块一起使用时，“ html2text”模块不起作用
