Question

阅读scrapy文档后，我认为默认情况下启用了HttpProxyMiddleware。但是当我通过scrapyd的webservice接口启动蜘蛛时，HttpProxyMiddleware未启用。我收到以下输出：

2013-02-18 23:51:01+1300 [scrapy] INFO: Scrapy 0.17.0-120-gf293d08 started (bot: pde)

2013-02-18 23:51:02+1300 [shotgunsupplements] INFO: Spider opened

请注意，未启用HttpProxyMiddleware。如何为scrapyd启用它？任何帮助将不胜感激。

我的scrapy.cfg

# Automatically created by: scrapy startproject
#
# For more information about the [deploy] section see:
# http://doc.scrapy.org/topics/scrapyd.html

[settings]
default = pd.settings

[deploy]
url = http://localhost:6800/
project = pd

我有以下settings.py

BOT_NAME = 'pd' #this gets replaced with a function
BOT_VERSION = '1.0'

SPIDER_MODULES = ['pd.spiders']
NEWSPIDER_MODULE = 'pd.spiders'
DEFAULT_ITEM_CLASS = 'pd.items.Product'
ITEM_PIPELINES = 'pd.pipelines.PdPipeline'
USER_AGENT = '%s/%s' % (BOT_NAME, BOT_VERSION)

TELNETCONSOLE_HOST = '127.0.0.1' # defaults to 0.0.0.0 set so
TELNETCONSOLE_PORT = '6073'      # only we can see it.
TELNETCONSOLE_ENABLED = False

WEBSERVICE_ENABLED = True

LOG_ENABLED = True


ROBOTSTXT_OBEY = False
ITEM_PIPELINES = [
    'pd.pipelines.PdPipeline',
    ]

DATA_DIR = '/home/pd/scraped_data' #directory to store export files to.

DOWNLOAD_DELAY = 2.0

DOWNLOADER_MIDDLEWARES = {
    'scrapy.contrib.downloadermiddleware.httpproxy.HttpProxyMiddleware': 750,
}

此致

在花费了很长时间尝试调试之后，事实证明HttpProxyMiddleware实际上需要设置http_proxy环境变量。如果未设置http_proxy，则不会加载中间件。因此，我设置http_proxy和bob是你的叔叔！一切正常！

在scrapyd中启用HttpProxyMiddleware
