Previously, the timeout exception was handled in download middleware, but it was always very laborious
Today, I checked the document and found that it can be processed in the errback callback
from scrapy.spidermiddlewares.httperror import HttpError
from twisted.internet.error import DNSLookupError
from twisted.internet.error import TimeoutError, TCPTimedOutError
yield scrapy.Request(url=full_url, errback=self.error_httpbin, dont_filter=True, callback=self.parse_list, meta={"hd": header})
def error_httpbin(self, failure):
# failure.request is the Request object, if you need to retry, directly yield can
# if failure.check(HttpError):
# these exceptions come from HttpError spider middleware
# you can get the non-200 response
# response = failure.value.response
# self.logger.error('HttpError on %s', response.url)
if failure.check(DNSLookupError):
print("DNSLookupError------->")
# this is the original request
request = failure.request
yield request
# self.logger.error('DNSLookupError on %s', request.url)
elif failure.check(TimeoutError, TCPTimedOutError):
print("timeout------->")
request = failure.request
yield request
# self.logger.error('TimeoutError on %s', request.url)
It is hereby recorded that the timeout exception has not been handled in this way before
The above problems were encountered when packaging a stand-alone Python environment. It is mainly caused by the inconsistency between the software execution environment and the compilation environment
That is, the environment in which Python is executed needs to be consistent with the environment in which Python is compiled. Specifically, python packaged under Linux cannot be executed under Mac
It is not easy to distinguish the python compilation environment, except that the official website gives an obvious distinction. In daily cooperation, it is common to lack corresponding documents corresponding to customized Python environment
You can use file program under Linux or Mac to view the compilation environment of the program.

When accessed through the browser, an error is reported
Key error message
TypeError: 'dict' object is not callable The view function did not return a valid response. The return type must be a string, tuple, Response instance, or WSGI callable, but it was a dict.
It means that dict cannot be returned

The result is that the version is too old. I used flash 1.0.2… I took it. I ran other people’s projects and installed an old version of flash. Just install the latest version
