我正在尝试使用以下代码将字典作为Json传递给Ajax请求:
Views.py
from rest_framework.response import Response
class ChartData8(APIView):
def tickets_per_day_results(request):
if request.method == "POST":
template_name = 'personal_website/tickets_per_day_results.html'
year = request.POST.get('select_year', None)
week = request.POST.get('select_week', None)
....do stuff...
data = {"label_number_days": label_number_days,
"days_of_data": count_of_days}
return render(request,template_name,{Response(data)})
Response
是我用来将数据转换为json格式的类,但后来我必须将其包装为字典{}
,这样我就可以避免错误context must be a dict rather than Response
。
template_1
$.ajax({
method: "POST",
url: endpoint,
dataType: 'json',
contentType: "application/json",
headers: {"X-CSRFToken": $.cookie("csrftoken")},
success: function(data){
console.log(data)
label_number_days = data.label_number_days
days_of_data = data.days_of_data
setChart()
},
error: function(jqXHR,error_data, errorThrown){
console.log("error on data")
console.log(error_data)
console.log(JSON.stringify(jqXHR))
console.log("AJAX error: " + error_data + ' : ' + errorThrown)
}
})
一切正常,直到浏览器抛出错误AJAX error: parsererror : SyntaxError: Unexpected token < in JSON at position 0
。这个错误是由于我被引导相信响应主体实际上是HTML而不是Json。
我的主要问题是:如何将结果转换为Json,以便Ajax可以顺利读取?

你需要看到几个错误。 APIView类不能包含像您实现的单个方法。你要么必须实现get或post。您可以阅读更多相关信息here
class ChartData8(APIView):
def post(self, request):
year = request.POST.get('select_year', None)
week = request.POST.get('select_week', None)
# ....do stuff...
data = {"label_number_days": label_number_days,
"days_of_data": count_of_days}
return Response(data)
