python - tornado.httpclient.AsyncHTTPClient如何使用代理请求一个http服务？

Answer 1

proxy_host (string) – HTTP proxy hostname. To use proxies, proxy_host and proxy_port must be set; proxy_username and proxy_pass are optional. Proxies are currently only supported with curl_httpclient.

To select curl_httpclient, call AsyncHTTPClient.configure at startup:

AsyncHTTPClient.configure("tornado.curl_httpclient.CurlAsyncHTTPClient")

Just take a look at the documentation. The proxy only supports curl_httpclient

Answer 3

httpclient.AsyncHTTPClient.configure(
            "tornado.curl_httpclient.CurlAsyncHTTPClient"
        )

This document explains that only curl_httpclient supports proxy, you need to configure it like this.
When using it, just add proxy parameters to the fetch function proxy_host="127.0.0.1", proxy_port=8787.
