腾讯云短信通过反向代理接收回执信息方案

方案背景

部分客户会在腾讯云短信配置回执URL（功能描述：短信下发给用户后，腾讯云短信服务可以通过回调业务 URL 的方式，通知业务方短信下发的状态），但是客户不希望直接把内部业务的机器配置成回执接收方，把IP暴露出去。

方案介绍

通过nginx添加一层反向代理实现转发，就可以对外隐藏内网机器的信息。

实施方案

准备：(系统：centos 7.6)

短信状态回调URL机器：外网不能直接访问，与代理机可以通信。 IP：172.16.0.9 A机

nginx代理机器：外网可以直接访问，与代理机可以通信。IP：159.75.219.99 B机

*资源有限，我用同一台机器的内外网IP分别当作A机和B机。

A机搭建短信回执接收接口

安装python环境（3.0+）

代码语言：javascript

复制

wget https://mirrors.tuna.tsinghua.edu.cn/anaconda/miniconda/Miniconda3-py39_4.9.2-Linux-x86_64.sh
bash Miniconda3-py39_4.9.2-Linux-x86_64.sh
source /root/.bashrc
conda -V
conda deactivate
conda create -n py39 python=3.9.2
conda activate py39
pip install flask

编写回执接收接口

代码语言：javascript

复制

# _*_ coding:utf-8 _*_
from flask import Flask

from flask import request
app=Flask(name)
@app.route("/proxy_callback",methods=["POST"])

def receiveResponse():

if request.method=="POST":

print(request.json)
return &#34;sms callback!&#34;

if name=="main":

app.run(host="172.16.0.9",port=9527,debug=True)

运行脚本

B机搭建nginx代理

编译安装nginx

代码语言：javascript

复制

wget http://nginx.org/download/nginx-1.20.1.tar.gz

tar xzvf nginx-1.20.1.tar.gz

cd nginx-1.20.1/

./configure --prefix=/usr/local/nginx --with-http_ssl_module --with-http_stub_status_module --with-http_realip_module --with-threads --with-stream

make && make install

nginx启动测试
