Question

我正在尝试在付款过程中要求提供结帐ID，这是我到目前为止的代码。下面的代码可以正常工作，并且我可以从中得到响应，但是，一旦我将一些注释的部分添加到数据字典中，它就会给我一个属性错误，即int没有对象获取。

基本上，我似乎只能将键，字符串或数字值添加到我的数据字典中，但是每当我将字典添加为值时，它就会开始给我错误。

我不知道为什么会这样，有人可以帮忙吗？预先感谢！

def request_checkout_id(request):

    user = request.user

    url = "https://xxxxxx"
    entity_id = 'xxxxx'
    auth_header = 'xxxxx'
    currency = 'USD'

    try:
        ref_code = request.session['ref_code']
        order = Order.objects.get(ref_code=ref_code)    
    except:
        ref_code = None
        return redirect(reverse('shop:cart'))

    amount = float(order.final_total)

    base_con_tarifa = order.cart.total
    valor_iva = order.cart.tax_total
    #total_con_iva = order.sub_total

    print(data)

    try:
        opener = urllib.request.build_opener(urllib.request.HTTPHandler)
        request_id = urllib.request.Request(url, data=urllib.parse.urlencode(data).encode('utf-8'))
        request_id.add_header('Authorization', auth_header)
        request_id.get_method = lambda: 'POST'
        response = opener.open(request_id)
        parsed_response = json.loads(response.read())
        checkout_id = parsed_response['id']
        print(checkout_id)
    except urllib.error.HTTPError as e:
        print(e.code)
        return e.code

    if checkout_id:
        payment = Pago()
        payment.order = order
        payment.ref_code = order.ref_code
        payment.user = request.user
        payment.checkout_id = checkout_id
        payment.save()
        return redirect(reverse('shop:checkout'))
    #else:
    #raise some error or alert

这是我的错误回溯：

对于将来阅读本文的任何人，请提供有关发生此错误的更简单实例以及我的解决方案。

# Python program for reading from file 

counts = dict() *# line that fixed it for me*

fname = input("Enter file name: ")

with open(fname) as fh:
    myfile = fh.read()
    words = list(myfile.split())

    for word in words:
        counts[word] = counts.get(word,0) + 1

print('counts', counts)

事实证明，如果您没有将计数定义为 dict() 类型，它将抛出相同的 AttributeError: 'int' object has no attribute 'get' 错误。我对 Python 很陌生，所以如果这个解决方案太基础，它的目的是针对也在学习的人。

Answer 2

正如注释中指出的那样，问题是在int情况下，您以HTTPError.code（HTTPError）的形式返回状态代码，而Django需要HTTPResponse。

处理此问题的最简单方法是替换此逻辑：

except urllib.error.HTTPError as e:
    print(e.code)
    return e.code

与此：

except urllib.error.HTTPError as e:
    print(e.code)
    return HttpResponse(status=e.code)

但是，根据您的应用程序，您可能需要更多的HTTPResponse。您可以在returning errors的Django文档中阅读更多内容。对于特定的状态代码，还有HTTPResponse的子类，因此，如果您知道错误代码为500，则可以返回HttpResponseServerError。

Answer 3

已经解决了。我只是以错误的格式传递数据。

属性错误：“ int”对象没有属性“ get”
