[英]python jsonify dictionary in utf-8
I want to get json data into utf-8我想将 json 数据转换为 utf-8
I have a list my_list = []
我有一个列表my_list = []
and then many appends unicode values to the list like this然后许多人像这样将 unicode 值附加到列表中
my_list.append(u'ტესტ')
return jsonify(result=my_list)
and it gets它得到
{
"result": [
"\u10e2\u10d4\u10e1\u10e2",
"\u10e2\u10dd\u10db\u10d0\u10e8\u10d5\u10d8\u10da\u10d8"
]
}
使用以下配置添加 UTF-8 支持:
app.config['JSON_AS_ASCII'] = False
Use the standard-library json
module instead, and set the ensure_ascii
keyword parameter to False when encoding, or do the same with flask.json.dumps()
:改用标准库json
模块,并在编码时将ensure_ascii
关键字参数设置为 False,或对flask.json.dumps()
执行相同flask.json.dumps()
:
>>> data = u'\u10e2\u10d4\u10e1\u10e2'
>>> import json
>>> json.dumps(data)
'"\\u10e2\\u10d4\\u10e1\\u10e2"'
>>> json.dumps(data, ensure_ascii=False)
u'"\u10e2\u10d4\u10e1\u10e2"'
>>> print json.dumps(data, ensure_ascii=False)
"ტესტ"
>>> json.dumps(data, ensure_ascii=False).encode('utf8')
'"\xe1\x83\xa2\xe1\x83\x94\xe1\x83\xa1\xe1\x83\xa2"'
Note that you still need to explicitly encode the result to UTF8 because the dumps()
function returns a unicode
object in that case.请注意,您仍然需要将结果显式编码为 UTF8,因为在这种情况下dumps()
函数返回一个unicode
对象。
You can make this the default (and use jsonify()
again) by setting JSON_AS_ASCII
to False in your Flask app config.您可以通过在 Flask 应用程序配置JSON_AS_ASCII
设置为 False使其成为默认值(并再次使用jsonify()
)。
WARNING : do not include untrusted data in JSON that is not ASCII-safe, and then interpolate into a HTML template or use in a JSONP API, as you can cause syntax errors or open a cross-site scripting vulnerability this way.警告:不要在非 ASCII 安全的 JSON 中包含不受信任的数据,然后插入 HTML 模板或在 JSONP API 中使用,因为这样可能导致语法错误或打开跨站点脚本漏洞。 That's because JSON is not a strict subset of Javascript , and when disabling ASCII-safe encoding the U+2028 and U+2029 separators will not be escaped to \
and \
sequences.这是因为JSON 不是 Javascript 的\
集,并且在禁用 ASCII 安全编码时, U+2028 和 U+2029 分隔符不会转义为\
和\
序列。
If you still want to user flask's json and ensure the utf-8 encoding then you can do something like this:如果您仍然想使用flask 的json 并确保使用utf-8 编码,那么您可以执行以下操作:
from flask import json,Response
@app.route("/")
def hello():
my_list = []
my_list.append(u'ტესტ')
data = { "result" : my_list}
json_string = json.dumps(data,ensure_ascii = False)
#creating a Response object to set the content type and the encoding
response = Response(json_string,content_type="application/json; charset=utf-8" )
return response
#I hope this helps #我希望这有帮助
In my case the above solution was not sufficient.就我而言,上述解决方案是不够的。 (Running flask on the GCP App Engine flexible environment). (在 GCP App Engine 柔性环境上运行 Flask)。 I ended up doing:我最终做了:
json_str = json.dumps(myDict, ensure_ascii = False, indent=4, sort_keys=True)
encoding = chardet.detect(json_str)['encoding']
json_unicode = json_str.decode(encoding)
json_utf8 = json_unicode.encode('utf-8')
response = make_response(json_utf8)
response.headers['Content-Type'] = 'application/json; charset=utf-8'
response.headers['mimetype'] = 'application/json'
response.status_code = status
