Python UnicodeDecodeError: 'ascii' codec ne peut pas décoder les octets 0xe2 ordinale pas in range(128)

Je suis en train d'écrire ma première application sur Google App Engine avec Python (lien de l'application: http://contractpy.appspot.com/ - c'est juste une application expérimentale). L'ensemble du code est ci-dessous.

Mais, quand je soumettre les données, j'obtiens cette erreur (montré sur les journaux):

(...) line 265, in get "contractType":geted_contractType
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 949: ordinal not in range(128)

Ligne 265 est dans ce bloc si:

self.response.out.write(yourcontract % {"resident":geted_resident_name,
                                      "nacionality":geted_user_nacionality,
                                      "SSN":geted_user_SSN,
                                      "SSN_error":geted_SSN_error,
                                      "driverLicense":geted_user_driverLicense,
                                      "email":geted_user_email,
                                      "witness ":geted_witness ,
                                      "owner":geted_owner,
                                      "contractType":geted_contractType
                                      })

J'ai essayé de faire des changements, lire les mêmes awnswers (comme cette ou cette), mais rien n'y fit. Je ne peux pas comprendre, dans ce code, ce qui ne va pas. Quelqu'un peut-il comprendre ce qui est à l'origine de cette erreur et comment la corriger?

J'utilise Python 2.7.

Merci d'avance pour toute aide!

Vérifiez ceci: bit.ly/unipain
avez-vous essayé encode('utf-8'), il peut résoudre votre problème

Vous devriez vraiment utiliser un bon système de template. Jinja2 est inclus avec AppEngine.

Toutefois, dans l'intervalle, votre problème, c'est que vos modèles sont en ASCII, mais vos données n'est pas (ne peut pas savoir si c'est de l'utf-8 ou unicode). La solution facile est de faire précéder chaque modèle de chaîne avec u à faire Unicode.

Mais, vous devriez vraiment utiliser un bon système de template.

Salut, @Daniel Roseman, je commencer à utiliser jinja2, mais, savez, je suis coincé avec cette erreur: stackoverflow.com/questions/11072478/... Pourriez-vous apporter de l'aide? Merci encore!

Ici vous avez la solution.

>>> "t".decode("utf-8")
u't'
>>> "\x81".decode("utf-8")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "encodings/utf_8.py", line 7799, in decode
UnicodeDecodeError: 'utf8' codec can't decode byte 0x81 in position 0: unexpected code byte
>>> "a\x81b".decode("utf-8", "replace")  # this will decode better and the right way.
u'a\ufffdb'

L'encodage dans votre exemple n'est pas allé mieux. Tout ce que vous avez réalisé est le remplacement d'un des caractères non-ASCII avec caractère Unicode FFFD. Je ne peux pas imaginer que le demandeur voudrait ce personnage à tourner dans ses données.

Par défaut codeur en haut de votre code

Dans appcfg.py qui réside à l'intérieur /google/appengine/tools/appcfg.py

sur la ligne 73 ajouter
```
import sys
reload(sys)
sys.setdefaultencoding("ISO-8859-1")
```
c'était la seule solution qui a fonctionné pour moi, j'ai essayé les deux autres et ils n'ont pas de travail. je vous remercie.
