下载ngrok,ngrok下载地址为:

Download ngrokDownload ngrokhttps://download.ngrok.com/windows?tab=download下载后有个ngrok.exe 文件，通过命令行指向这个exe路径，然后启动ngrok

ngrok http 5000

安装flask

pip3 install flash

编写代码:

from flask import Flask,request,jsonify
from loguru import logger

app=Flask(__name__)

@app.route('/sms',methods=['POST'])
def receive():
    sms_content=request.form.get('content')
    logger.debug(f'receive:{sms_content}')
    return jsonify({'code':200,'msg':'success'})

@app.route('/test',methods=['GET'])
def test():
    return jsonify({'code':200,'msg':'success'})


if __name__=='__main__':
    app.run(port=5000)
 

运行后报错:

Use "ngrok [command] --help" for more information about a command.

ERROR:  authentication failed: The authtoken you specified does not look like a proper ngrok tunnel authtoken.
ERROR:  Your authtoken: 2UG6Y8PFPV
ERROR:  Instructions to install your authtoken are on your ngrok dashboard:

ERROR:

ERROR:  https://ngrok.com/docs/errors/err_ngrok_105
ERROR:

从报错信息看，是ngrok缺少Authtoken

进入ngrok的官网，注册后获取authtoken：

ngrok - Online in One Line

添加authtoken

ngrok config add-authtoken 2rHjQ2xtFblXxmMe1VnyBvwtbjj_fiM5tFZoBUYyNZeGtjMw

问题解决，这样就可以通过外网穿透内网，直接在其他手机或网络访问本机对应的5000端口的flask API web了
