Les requêtes python ne peuvent pas trouver de dossier avec un certificat lors de la conversion en .exe

Question

J'ai un programme qui regroupe les statistiques d'annonces provenant de différents systèmes marketing. Tout fonctionne bien jusqu'à ce que je le convertisse au format .exe et l'exécute.

Exception in Tkinter callback

OSError: Could not find a suitable TLS CA certificate bundle, invalid path: C:\Users\user\AppData\Local\Temp\_MEI253762\facebookads\fb_ca_chain_bundle.crt 

J'ai essayé de résoudre ce problème en utilisant ce code, mais le dossier MEI change constamment ses chiffres à chaque fois que je lance ce code il est donc inutile.

dst = r'C:\Users\user\AppData\Local\Temp\_MEI120642\facebookads' 
file = 'fb_ca_chain_bundle.crt' 

try: 
    os.makedirs(dst); ## it creates the destination folder 
except: 
    pass 

shutil.move(file, dst) 

Je suis donc allé dans ce fichier

C: \ Users \ user \ AppData \ Local \ Programmes \ Python \ Python35 \ Lib \ site-packages \ demandes \ adapters.py

et essayé de commenter si des déclarations qui soulèvent cette erreur mais ont obtenu une erreur SSL. Je n'ai pas pu trouver un morceau de code responsable de la génération de ces chiffres MEI.

Answer 1

J'ai également rencontré ce problème. Il semble que cela provient du regroupement de certificats cacert.pem qui n'est pas inclus dans le répertoire du package requests lorsque le programme est compilé. Le module requests utilise la fonction certifi.core.where pour déterminer l'emplacement de cacert.pem. Remplacer cette fonction et remplacer les variables définies par cette fonction semble résoudre le problème.

J'ajouté ce code au début de mon programme:

import sys, os 


def override_where(): 
    """ overrides certifi.core.where to return actual location of cacert.pem""" 
    # change this to match the location of cacert.pem 
    return os.path.abspath("cacert.pem") 


# is the program compiled? 
if hasattr(sys, "frozen"): 
    import certifi.core 

    os.environ["REQUESTS_CA_BUNDLE"] = override_where() 
    certifi.core.where = override_where 

    # delay importing until after where() has been replaced 
    import requests.utils 
    import requests.adapters 
    # replace these variables in case these modules were 
    # imported before we replaced certifi.core.where 
    requests.utils.DEFAULT_CA_BUNDLE_PATH = override_where() 
    requests.adapters.DEFAULT_CA_BUNDLE_PATH = override_where()
