python如何通过代理服务器连接mysql?

python如何通过代理服务器连接mysql?,第1张

你的虚拟服务器不是在aws么,你的mysql应该在aws服务器上吧,那么连接mysql就不需要使用代理服务器,直接使用本地连接就是了。

如果解决了您的问题请采纳!

如果未解决请继续追问

i think this should look like..

applet

jdbc->lokal server someport

lokal sever someport

get data_for_sqlserver

embed data_for_sqlserver ->post_http_data_for_sqlserver

socket port 80->http://yourwebserver/servlet

send post_http_data_for_sqlserver (use POST)

is this ok for u ?

remote server with servlet

getPost post_http_data_for_sqlserver

unwrap post_http_data_for_sqlserver ->data_for_sqlserver

socket->mysql on right port

send data_for_sqlserver

receive data_from_sqlserver

embed data_from_sqlserver ->http_response_data_from_sqlserver

sendResponse http_response_data_from_sqlserver

lokal server someport

receive http_response_data_from_sqlserver

unwrap http_response_data_from_sqlserver ->data_from_sqlserver

send data_from_sqlserver

applet

jdbc.get data_from_sqlserver ->ResultSet

as you can see this is a lot of work and im not sure if you can open a

serverport in untrusted applets.

so if you can connect to port 80 without a runing webserver you can

write your own jdbc-redirect-proxy

applet

jdbc->your jdbcproxy on port 80

jdbcproxy

get data_to_sqlserver

socket->mysql on right port

send data_to_sqlserver

get response ->data_from_sqlserver

send data_from_sqlserver

applet

jdbc.get data_from_sqlserver ->ResultSet

如何用java 5分钟实现一个最简单的mysql代理服务器

首先,准备开发工具套件,我们并不会引入过多工具包,仅仅需要:

java8

vert.x 3

如果你是用maven做为项目管理工具,请将vert.x 3引入:

<dependency>

<groupId>io.vertx</groupId>

<artifactId>vertx-core</artifactId>

<version>3.3.2</version>
