之前已经用Flask-restful设计好了对应的api接口
但是只支持英文字符串
如果在POST接口中，传入带中文的JSON字符串时：
{ “email”: “[email protected]”, “facebookUserId”: “157731344684905”, “firstName”: “三”, “lastName”: “张”, “password”: “111111”, “phone”: “13711112222”, “smsCode”: “891527” } |
就会报错，说无法解析
{ “message”: { “firstName”: “‘ascii’ codec can’t encode character u’\\u4e09′ in position 0: ordinal not in range(128)” } } |
如图：
搜：
flask-restful ‘ascii’ codec can’t encode character u’\\u4e09′ in position 0: ordinal not in range(128)
flask-restful ascii codec can’t encode character in position 0 ordinal not in range(128)

说是换成：
type=unicode
或者不指定type，则默认为unicode？
Blog: Encoding and Python: The UnicodeDecodeError exception
然后用unicode：
class RegisterAPI(Resource): def __init__(self): self.reqparse = reqparse.RequestParser() self.reqparse.add_argument(‘phone’, type = unicode, default = “”, location = ‘json’) self.reqparse.add_argument(‘smsCode’, type = unicode, default = “”, location = ‘json’) self.reqparse.add_argument(’email’, type = unicode, default = “”, location = ‘json’) self.reqparse.add_argument(‘firstName’, type = unicode, default = “”, location = ‘json’) self.reqparse.add_argument(‘lastName’, type = unicode, default = “”, location = ‘json’) self.reqparse.add_argument(‘password’, type = unicode, default = “”, location = ‘json’) self.reqparse.add_argument(‘facebookUserId’, type = unicode, default = “”, location = ‘json’) super(RegisterAPI, self).__init__() |
就可以用中文注册了：
顺带再去看看：
flask-restful RequestParser add_argument type
看看add_argument的type，到底有哪些类型的值

Intermediate Usage — Flask-RESTful 0.2.1 documentation
-》type=int
post_parser.add_argument( ’email’, dest=’email’, type=email, location=’form’, required=True, help=’The user\’s email’, ) post_parser.add_argument( ‘user_priority’, dest=’user_priority’, type=int, location=’form’, default=1, choices=range(5), help=’The user\’s priority’, ) |
其中email是自定义的：
def email(email_str): “””Return email_str if valid, raise an exception in other case.””” if valid_email(email_str): return email_str else: raise ValueError(‘{} is not a valid email’.format(email_str)) |
Request Parsing — Flask-RESTful 0.2.1 documentation
-》
parser.add_argument(‘picture’, type=werkzeug.datastructures.FileStorage, location=’files’) |
Only use type=list when location=’json’. See this issue for more details
具体的定义：
API Docs — Flask-RESTful 0.2.1 documentation
但是没有更具体的解释：
“type – The type to which the request argument should be converted. If a type raises an exception, the message in the error will be returned in the response. Defaults to unicode in python2 and str in python3.”
不过知道了：
默认是unicode字符串：
python2是unicode
python3是str

【总结】
想要让Flask-restful中传入字符串参数支持中文的话，则需要：
设置参数的类型为unicode：
1.默认不设置type，即可默认为unicode
2.如果设置，则指明：type=unicode
<code>class RegisterAPI(Resource):
def __init__(self):
self.reqparse = reqparse.RequestParser()
...
self.reqparse.add_argument('firstName',
type = unicode,
default = "",
location = 'json')
</code>3.其它的，目前已知的type，逻辑上是允许任何目前已有的类型，且支持自定义类型
4.目前见过的：
（1）已有类型有：
type=str
注：python2中str表示普通字符串
如果是python3，则str表示unicode了，注意不要搞混了。
type=unicode
type=init
type=list, location=“json”
type=werkzeug.datastructures.FileStorage
（2）自定义类型有：
<code>def email(email_str):
"""Return email_str if valid, raise an exception in other case."""
if valid_email(email_str):
return email_str
else:
raise ValueError('{} is not a valid email'.format(email_str))
post_parser.add_argument(
'email', dest='email',
type=email, location='form',
required=True, help='The user\'s email',
)
