twisted的getPage已经不建议使用,新接口为twisted.web.client.Agent

李魔佛 发表了文章 • 2 个评论 • 630 次浏览 • 2019-07-12 11:31 • 来自相关话题

Twisted-16.7.0 is coming soon, and it deprecates twisted.web.client.getPage (and client.HTTPClientFactory). We use these in some of the unit tests, to fetch one of the HTTP WAPI/WUI pages and make sure the contents look right.

We need to change these tests to use twisted.web.client.Agent instead, or a package named "treq", which is a Twisted flavor of the excellent (but blocking) requests library.

js里面的内容有中文的换行符。
使用正则表达式替换换行符。(也可以替换为任意字符)js=re.sub('\r\n','',js)
完毕。

出现这个情况,一般是因为装了一些插件,比如屏蔽广告的插件 ad block导致的。
把插件卸载了问题就解决了。

pycharm debug scrapy 报错 twisted.internet.error.ReactorNotRestartable

没发现哪里不妥,以前debug调试scrapy一直没问题。 
后来才发现,
scrapy run的启动文件名不能命令为cmd.py !!!!!
我把scrapy的启动写到cmd.py里面
from scrapy import cmdline cmdline.execute('scrapy crawl xxxx'.split())
 
然后cmd.py和系统某个调试功能的库重名了。 查看全部

CentOS Zookeeper无法启动:Error contacting service,It is probably not running

启动:
./kafka-server-start.sh -daemon ../config/server.properties
报错:
Error contacting service,It is probably not running
 
关闭重启,杀进程,看端口是否被占用。无果。
后来看了下防火墙,OMG,有一台机子的防火墙没有关闭。
 
手工关闭后问题就解决了。
 
关闭防火墙命令:
systemctl stop firewalld.service #关闭防火墙
systemctl disable firewalld.service #禁止启动防火墙 查看全部
