ResponseCashedProxy

This utility works like a regular proxy, but at the same time it caches the response from the service in RAM and, if this service is unavailable, returns the last successful response.

Utility Features

1. Setting a timeout from the service
2. Base64Encoding of params in the request path by key
3. Append params to the request path
4. Search strings in response by regEx and replace them with custom string

Console arguments

Arg	Required	Default value	Description
--util_port	False	9119	Port on which the proxy web server will start
--config_file	False	config.json	File name with configs. File must be placed in config folder near main.py

Instruction for JSON config file

First of all, you need to create config folder near main.py file. Then create inside this folder blank new file. Strongly recommended to create file with name config.json, because in the future it is not expected to enter a console argument --config_file.

JSON config keys

Key	Required	Default value	Type	Description	Example
link	True	Null	String	Link to service	"link": "https://<host>"
ssl_verify	False	False	Boolean	Ignore SSL verify	"ssl_verify": false
timeout	False	10	Integer	Timeout from service	"timeout": 2
base64_keys	False	Null	JsonArray[String]	Param keys for base64Encoding	"base64_keys": ["email"]
append_param	False	Null	JsonObject{String(request path): String(append params)}	Append params to the request path	"append_param": {"/modss": "?email=*****&logged=true"}
strings_for_replace	False	Null	JsonObject{String(request path): {String(regEx): String(custom string)}}	Request path where need to set a custom string by regEx	"strings_for_replace": {"/modss": {"API \\+ 'EPG'": "'http://10.10.0.21:9120/EPG'", "API \\+ 'tvPL'": "'http://10.10.0.21:9120/tvPL'"}

JSON config Example

{
  "link": "https://lampa.stream",
  "ssl_verify": false,
  "timeout": 5,
  "base64_keys": [
    "email"
  ],
  "append_param": {
    "/modss": "?email=**********&logged=true"
  },
  "strings_for_replace": {
    "/modss": {
      "API \\+ 'EPG'": "'http://10.10.0.21:9120/EPG'",
      "API \\+ 'tvPL'": "'http://10.10.0.21:9120/tvPL'"
    }
  }
}
