Question

我正在尝试使用Gspread在Django中为Google电子表格构建一个REST API，我遇到了很多问题（所以如果有人碰巧有一个完整的例子，请随时分享.. 。请？：））。其中一个问题是我尝试接收POST请求的JSON（当然还有其他请求）。然而，这是失败的。这是我的代码：

view.py（我知道IF语句不是它的工作方式



$days = current($days); 

while($days <= 66){

echo  $days; 

next ($days); 

if (end ($days)){

reset($days); 

}

为此编写的测试：

elif request.method == 'POST':
    received_json_data = json.loads(request.body.decode("utf-8"))
    content = received_json_data['content']
    if content != "":
        worksheet.insert_row([content["date"], content["days"], content["firstname"], content["lastname"], content["team"], content["training"], content["company"], content["city"], content["cost"], content["invoice"], content["info"]], 1)
        return JsonResponse(content, safe=False, status=status.HTTP_201_CREATED)
    else:
        return JsonResponse([], safe=False, status=status.HTTP_400_BAD_REQUEST)

training_json_body的内容：

def test_post_all_training_returns_201_when_correct_format(self):
    """
    A POST request on /trainings/ should create a new training
    """
    headers = {'content-type': 'application/json'}
    response = self.client.post('/trainings/', json=json.dumps(self.training_json_body), headers=headers, format="json")
    self.assertEqual(response.status_code, status.HTTP_201_CREATED)

回溯

self.training_json_body = {
    "date": "1/1/2018",
    "days": 1,
    "firstname": "Data",
    "lastname": "Data",
    "team": "Data",
    "training": "Data",
    "company": "Data",
    "city": "Data",
    "cost": 1,
    "invoice": "Data",
    "info": "Data"
}

我已经搜索了几天的解决方案，但是无法让它发挥作用，所以如果有人能够把我推向正确的方向，我会非常感激。

我已将代码更新为以下内容：

这不再引发任何错误，但是append_row（）函数现在正在添加＆＃34;无＆＃34;对于每个领域，显然数据仍未通过。我该如何解决这个问题？

Answer 1

如果您正在使用Django REST框架，那么您可以通过访问double* get_real() const { return real; }字典（more info here）轻松地从请求对象获取数据。

如果您使用的是vanilla django视图，则可以使用请求对象访问POST数据并访问request.data或`request.POST.get（''）。例如：

request.POST['<field_name>']

您可以阅读更多相关内容或查看示例here。

Answer 2

尝试一下：

request.data.get("sheet")

Answer 3

要获取Json格式的参数，您需要将请求的子方法从“ GET”更改为“ DATA”，如下所示：

sheet = request.data.get("sheet")

使用REST Framework从Django中的POST获取JSON数据
