1. ajax 和 JSON.stringify($(“form”).serialize())

$.ajax({
                url: $SCRIPT_ROOT + '/login',
                type: "post",
                contentType : "application/json",
                data: JSON.stringify($("form").serialize()),
                dataType: 'json',
                success: function
 
 (data) {
                    $("#name").text(data.result);
                }
            })

後臺接收:

data = request.get_json()
print(type(data),data) #<class 'str'> username=2&password=2(url格式)
# 將url轉換成dict
import urllib.parse
data = dict(urllib.parse.parse_qsl(data))
print(type(data), data
 
) #<class 'dict'> {'password': '2', 'username': '2'}
a = data.get('username')
b = data.get('password')
print(a,b)
return jsonify(result=int(a) + int(b))

2.ajax 和 $(“form”).serialize()

$.ajax({
                url: $SCRIPT_ROOT + '/login',
                type: "post",
                data: $("form"
 
).serialize(),
                dataType: 'json',
                success: function (data) {
                    $("#name").text(data.result);
                }
            })

後臺接收:

data = request.get_data(as_text=True)
print(type(data),data) #<class 'str'> username=2&password=2(url格式)
# 將url轉換成dict
import urllib.parse
data = dict(urllib.parse.parse_qsl(data))
print(type(data), data) #<class 'dict'> {'password': '2', 'username': '2'}
a = data.get('username')
b = data.get('password')
print(a,b)
return jsonify(result=int(a) + int(b))

3.ajax 和 obj

$.ajax({
                url: $SCRIPT_ROOT + '/login',
                type: "post",
                data: $("form").serialize(),
                dataType: 'json',
                success: function (data) {
                    $("#name").text(data.result);
                }
            })

後臺接收:

data = request.get_data(as_text=True)
print(type(data),data) #<class 'str'> username=2&password=2
a = data.get(' ')
b = data.get(' ')
print(a,b)
return jsonify(result=int(a) + int(b))

4.ajax 和 json資料

$.ajax({
                url: $SCRIPT_ROOT + '/login',
                type: "post",
                data: $("form").serialize(),
                dataType: 'json',
                contentType : "application/json",
                success: function (data) {
                    $("#name").text(data.result);
                }
            })

後臺接收:

data = request.get_json()
print(type(data),data) #<class 'str'> username=2&password=2
a = data.get(' ')
b = data.get(' ')
print(a,b)
return jsonify(result=int(a) + int(b))
