TypeError:+：“WSGIRequest”和“str”的操作数类型不受支持

Question

从最近几天开始，我一直坚持这样做，我想将.NS字符串加入到index函数传递的参数中，并将该字符串用于web.DataReader（）

def index(request):
if request.method == 'POST':
    search = request.POST['search']
    graph_data(search)



def graph_data(request):
requestp = request
ex = '.NS'
st_name = requestp+ex
df = web.DataReader(st_name, data_source='yahoo', start='2019-01-01', end='2020-03-16')

错误：-

TypeError: unsupported operand type(s) for +: 'WSGIRequest' and 'str'

Answer 1

我认为在使用+

def index(request):
    if request.method == 'POST':
        search = request.POST['search']
        graph_data(search)

def graph_data(request):
    requestp = request
    ex = '.NS'
    st_name = str(requestp) + ex
    df = web.DataReader(st_name, data_source='yahoo', start='2019-01-01',
                        end='2020-03-16')
