Question

Hey, aucune idée de ce qui est l'erreur de délai d'attente que je reçois ici:

trace d'erreur:

Voici le code qui s'appelle :

def get_posted_file(request, form_field_name, tgt_folder, tgt_fname=None):                      
     logger.debug('get_posted_file: %s' % request.headers['Last-Modified'])                      

     lowerHeaderMap = {}                                   
     for key, value in request.headers.items():                             
      lowerHeaderMap[key.lower()] = value                              

---> dataDict = TmpFieldStorage(fp=request.rfile, headers=lowerHeaderMap, environ={'REQUEST_METHOD':'POST'}              
            , keep_blank_values=True)                           

et:

class TmpFieldStorage(cgi.FieldStorage):                               
    """

    """                                       
    def make_file(self, binary=None):                                
     tmp_folder = os.path.join(get_filer_root(cherrypy.request.login), 'sync_tmp')                    
     if not os.path.exists(tmp_folder):                              
      os.makedirs(tmp_folder)

Answer 1

environ = { 'REQUEST_METHOD': 'POST'}

qui semble un environ plutôt déficient. La spécification CGI nécessite beaucoup plus de variables d'environnement, dont certaines auront besoin du module cgi.

En particulier, il n'y a pas d'en-tête CONTENT_LENGTH. Sans cela, cgi est par défaut pour lire tout le contenu du flux jusqu'à EOF. Mais puisqu'il s'agit (probablement) d'un flux réseau plutôt que d'un fichier, il n'y aura pas d'EOF (ou du moins pas directement à la fin de la soumission), donc le lecteur de formulaires sera assis là à attendre plus de données. . Temps libre.
