Flask Python,尝试将列表或字典返回给Ajax调用

在Flask应用中,我有以下ajax调用:

    $.ajax({

url: "{{ url_for( 'bookings.get_customer' ) }}",

type: "POST",

data: nameArray,

success: function( resp ){

console.log( resp )

}

})

如你所见,我正在传递一个数组,我将在该数组上搜索我的mongo数据库,该数据库将返回或不返回客户。

因此,负责处理此ajax调用的python def是:

@bookings.route( '/get_customer', methods=[ 'POST' ] )

def get_customer():

name = {}

for key, value in request.form.items():

name[ key ] = value

customer_obj = customer_class.Customer()

results = customer_obj.search_customer( name )

return results

为了论证,可以说customer_obj调用返回以下列表:

[{'customer': {

u'first_name': u'Dave',

u'tel': u'0121212121458',

u'country': u'UK',

u'address2': u'Townington',

u'address3': u'Cityville',

u'email': u'dave@smith.com',

u'postcode': u'A10 5BC',

u'address1': u'10 High Street',

u'second_name': u'Smith'

},

'customer_id': u'DaveSmithA10 5BCCat_Vegas1346244086'

}]

当我尝试将其返回给ajax调用时

return results

我收到以下错误:

 TypeError: 'list' object is not callable

这是回溯:

Traceback (most recent call last):

File "/usr/local/lib/python2.7/dist-packages/flask/app.py", line 1701, in __call__

return self.wsgi_app(environ, start_response)

rv = self.response_class.force_type(rv, request.environ)

File "/usr/local/lib/python2.7/dist-packages/werkzeug/test.py", line 818, in

run_wsgi_app

app_iter = app(environ, start_response)

TypeError: 'list' object is not callable

有没有人有什么建议?

回答:

Flask不希望你list从视图函数返回对象。尝试jsonify之前:

from flask import jsonify

@bookings.route( '/get_customer', methods=[ 'POST' ] )

def get_customer():

name = {}

for key, value in request.form.items():

name[ key ] = value

customer_obj = customer_class.Customer()

results = customer_obj.search_customer( name )

return jsonify(customers=results)
