Apart from altering the environment variable, I'll present what I found in the code.

Since boto3 uses botocore, I had a look through the source code:

<a href="https://github.com/boto/botocore/blob/66008c874ebfa9ee7530d944d274480347ac3432/botocore/endpoint.py#L265" rel="nofollow noreferrer">https://github.com/boto/botocore/blob/66008c874ebfa9ee7530d944d274480347ac3432/botocore/endpoint.py#L265</a>

From this link, we end up at:

<pre><code> def _get_proxies(self, url):
 # We could also support getting proxies from a config file,
 # but for now proxy support is taken from the environment.
 return get_environ_proxies(url)
</code></pre>

...which is called by <code>proxies = self._get_proxies(final_endpoint_url)</code> in the <code>EndpointCreator</code> class.

Long story short, if you're using python2 it will use the <code>getproxies</code> method from urllib2 and if you're using python3, it will use urllib3.

<code>get_environ_proxies</code> is expecting a dict containing <code>{'http:' 'url'}</code> (and I'm guessing <code>https</code> too).

You could always <code>patch</code> the code, but that is poor practice.

blocks|key|3348813|text|这是我推荐猴子补丁的罕见情况之一，至少在Boto开发人员允许特定于连接的代理设置之前：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3348814|import+botocore.endpoint
def+_get_proxies(self,+url):
++++return+{'http':+'http://someproxy:1234/',+'https':+'https://someproxy:1234/'}

This is one of the rare occasions when I would recommend monkey-patching, at least until the Boto developers allow connection-specific proxy settings:

<pre><code>import botocore.endpoint
def _get_proxies(self, url):
 return {'http': 'http://someproxy:1234/', 'https': 'https://someproxy:1234/'}
botocore.endpoint.EndpointCreator._get_proxies = _get_proxies
import boto3
</code></pre>

blocks|key|1632178|text|至少在1.5.79版本中，botocore在botocore配置中接受一个proxies参数。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1632179|例如：|1632180|import+boto3

As of at least version 1.5.79, botocore accepts a <code>proxies</code> argument in the botocore config.

e.g.

<pre><code>import boto3
from botocore.config import Config

boto3.resource('s3', config=Config(proxies={'https': 'foo.bar:3128'}))
</code></pre>

boto3 resource
<a href="https://boto3.readthedocs.io/en/latest/reference/core/session.html#boto3.session.Session.resource" rel="noreferrer">https://boto3.readthedocs.io/en/latest/reference/core/session.html#boto3.session.Session.resource</a>

botocore config
<a href="https://botocore.readthedocs.io/en/stable/reference/config.html#botocore.config.Config" rel="noreferrer">https://botocore.readthedocs.io/en/stable/reference/config.html#botocore.config.Config</a>

On the old <code>boto</code> library is was simple enough to use the <code>proxy</code>, <code>proxy_port</code>, <code>proxy_user</code> and <code>proxy_pass</code> parameters when you open a connection. However, I could not find any equivalent way of programmatically define the proxy parameters on boto3. :(

How do you use an HTTP/HTTPS proxy with boto3?

在旧的boto库中，在打开连接时可以使用proxy、proxy_port、proxy_user和proxy_pass参数。但是，我无法找到任何类似的方法，以编程方式在boto3上定义代理参数。:(
