Flask + ngrok public account construction test, flaskngrok

Using ngrok + flask to build a public platform consists of three steps: 1. ngrok configuration; 2. Public platform configuration; 3. flask construction. Shows the basic data flow trend:

 

1. ngrok Configuration

Ngrok provides an intranet-to-Internet ing tool for users who use nat to access the Internet and have no Internet address resources. It can access intranet resources through the Internet.

First download the ngrok tool from the ngrok official website. This version is 2.1.18. It is used in win7 and the command is ngrok.exe http 80.

As shown in, the link circled in blue is an external link, which is mapped to port 80 of the local machine. If flask is used, you need to change 80 to the default port 5000 or custom port of flask. In this way, you can access the corresponding resources on the public network by copying the link.

Ngrok can also add the parameter-subdomain = xxx to customize the sub-domain name. However, currently, the fee is charged, and the basic fee is USD 5/month to enjoy the service. It is worth noting that if you do not buy its service, the link changes every time you enable ngrok.

 

2. Public platform Configuration

The public platform configuration includes two steps: 1. write the authentication code on the server. For details about the authentication code, see the development documentation. 2. set the authentication link on the public platform, as shown in:

The public platform configuration mainly involves entering the required verification link on the basic configuration interface. If the verification is in the root directory of the link in step 1, you can directly copy the token. the token can be set at will, but ensure that the settings here are consistent with those in the code.

Def wechat_auth (): if request. method = 'get': if len (request. args)> 3: token = 'xxxxxxx' query = request. args signature = query ['signature'] timestamp = query ['timestamp'] nonce = query ['nonce '] echostr = query ['echostr'] s = [timestamp, nonce, token] s. sort () s = ''. join (s) sha1str = hashlib. sha1 (s. encode ('utf-8 ')). hexdigest () if sha1str = signature: return make_response (echostr) else: return make_response ("authentication failed") else: return "authentication failed"
