The JSONEncoder checkbox is set to provide_ascii for False

Question

I am working on a small flash application in which I want to return strings containing umlauts (in general, German special characters, for example 'ß'). Since the default JSONEncoderin flask has ensure_ascii=True, this will always convert my string

Hauptstraße 213

:

Hauptstra\u00dfe 213

My first approach was to simply create a very simple custom JSONEncoder

class NonAsciiJSONEncoder(json.JSONEncoder):
    def __init__(self, **kwargs):
        super(NonAsciiJSONEncoder, self).__init__(kwargs)
        self.ensure_ascii = False 

If I use this by setting

app.json_encoder = NonAsciiJSONEncoder

my return jsonify(...)will actually return a string containing 'ß'.

However, since this ensure_asciiis the default Encoder attribute, I thought it would be better to change it by setting it toFalse

app.json_encoder.ensure_ascii = False

False, . - 'ß', \u00df.

, , Encoder, False?

Answer 1

app.json_encoder.ensure_ascii, .

JSONEncoder.__init__ method True, ensure_ascii. class , __init__ , .

, False:

class NonASCIIJSONEncoder(json.JSONEncoder):
    def __init__(self, **kwargs):
        kwargs['ensure_ascii'] = False
        super(NonASCIIJSONEncoder, self).__init__(**kwargs)
