Implement the Syncrnous set URL to a dARK pid

If a dARK pid does not have a URL, the pid is still a draft. The on-chain dARK contracts (the blockchain or backend of the dARK) do not allow a user to set a payload or add an external pid to a draft pid. For further details, see our doc/ dark repositories.

This method should:

• Check if the user submits a valid url

In summary, until this method is invoked, the blockchain will mark a dARK pid as a draft. Therefore this method should be the second to be implemented.

Regarding the URL valid check, we assume a simple validation schema detailed below.

The URL must start with:

• http:// (upper and lower case)
• https:// (upper and lower case)

This pid validation method must be configured using a system variable HYPERDRIVE_URL_VALIDATION. If the variable is unset it must consider NONE validation method.

The HYPERDRIVE_URL_VALIDATION must be :

parameter value	description	default
NONE	No validation will be performed	✅
BASIC	Perform the validation described here	❌

For further information regarding the System Variable see #16

olá @thiagonobrega

sobre essa variável de sistema, você ainda está trabalhando nela ? você que disponibilizará para nós ?

about this system variable, are you still working on this? will you make it available?

olá @thiagonobrega
essa url seria a url da rota completa ? ou um pid tem uma url de pré fixo, onde eu consigo ver um exemplo de pid com url ?

A dARK pid has one attribute to store a URL.

https://github.com/dark-pid/dARK/blob/master/docs/diagrams/dark_core_entites_class.mmd

This URL is a simple web. For instance, http://www.uol.com and https://uepb.edu.br are valid URLs. One method to validate url are employing regular expression. The following is an example of one:

import re
 
def chek_url(url_str):
 
    regex = ("((http|https)://)(www.)?" +
             "[a-zA-Z0-9@:%._\\+~#?&//=]" +
             "{2,256}\\.[a-z]" +
             "{2,6}\\b([-a-zA-Z0-9@:%" +
             "._\\+~#?&//=]*)")
     
    # Compile the ReGex
    p = re.compile(regex)
 
    if (url_str== None):
        return False

    if(re.search(p, url_str)):
        return True
    else:
        return False

You and @fransilva0 can create a class (python file) to centralize all validations. For example, util/validation.py to store all validations.

@thiagonobrega implementei essa classe na branch feature/set_external_links se possível da uma olhada e fala para a gente um feedback, sobre essa questão de validação de link para saber se um pid é um rascunho, gostaria de entender melhor isso.

nos meus testes estou tendo esse erro:

{'code': -32000, 'message': 'Execution reverted', 'data': '0x08c379a0000000000000000000000000000000000000000000000000000000000000002000000000000000000000000000000000000000000000000000000000000000147575696420646f6573206e6f7420657869737473000000000000000000000000'}

Mas acredito que é por causa que estou passando um pid que é considerado um rascunho

[samuelfsd]

olá @thiagonobrega

poderia explicar melhor sobre essa variavél de sistema, acredito que só falta isso para terminar a implementação desse endpoint.
