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")

稍微看看文件就好了 代理只支援 curl_httpclient

Answer 2

代理目前僅支援curl_httpclient。

透過http://www.tornadoweb.org/en/stable/httpclient.html#tornado.httpclient.HTTPRequest

Answer 3

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

這篇文件有說明，只有curl_httpclient支援代理，你需要這樣設定。
使用的時候給fetch函數加上代理參數就行proxy_host="127.0.0.1", proxy_port=8787。
