问题描述:
使用tornado时,要用proxy,一直不通,但是也没报错。
response = await AsyncHTTPClient().fetch(
HTTPRequest(
url="",
validate_cert=False,
proxy_host=PROXY_HOST,
proxy_port=PROXY_PORT,
proxy_username=PROXY_USERNAME,
proxy_password=PROXY_PASSWORD
)
)
然后发现是AsyncHTTPClient这个东西要配成curl_httpclient才可以,不然默认的是simple_httpclient不能用proxy。(把我坑吐了)
官方文档里的:
proxy_host (str) – HTTP proxy hostname. To use proxies, proxy_host and proxy_port must be set; proxy_username, proxy_pass and proxy_auth_mode are optional. Proxies are currently only supported with curl_httpclient.
怎么配呢?
AsyncHTTPClient.configure("tornado.curl_httpclient.CurlAsyncHTTPClient")
然后跑起来之后这行代码又报错,给我整无语了????
ImportError: pycurl: libcurl link-time ssl backends (secure-transport, openssl) do not include compile-time ssl backend (none/other)
看不懂,字面意思就是openssl没找到还是啥的,我就去重新装了下openssl,然后mac 装的好麻烦。。。气死个人
首先卸载当前的pycurl
pip uninstall pycurl
export PYCURL_SSL_LIBRARY=openssl
pip install pycurl --no-cache-dir # 要加--no-cache-dir
如果不行的话,再设置几个变量
(后来发现下面的我好像没设成功????。。。主要是install的时候加上–no-cache-dir)
先找出你的ssh在哪
sudo find / -iname ssl.h
your-name:~$ export PYCURL_SSL_LIBRARY=openssl
your-name:~$ export LDFLAGS=-L安装目录/lib
your-name:~$ export CPPFLAGS=-I安装目录/include
