无法在后端解码post请求正文

backend django python

ScalaBoy · 技术社区 · 6 年前

我将post请求体中的json数据发送到python后端(django)。在后端,我接收到以下内容:

body_unicode = request.body.decode('utf-8')
print(body_unicode)

但如果我这样做,我会犯错误:

body_unicode = request.body.decode('utf-8')
body = json.loads(body_unicode)
print(body)

错误:

更新:

如果我这样做:

sample_data = request.POST['csvData']

print("sample_data",sample_data)

然后出现此错误:

    sample_data = request.POST['csvData']
  File "/Users/tuter/anaconda3/lib/python3.6/site-packages/django/utils/datastructures.py", line 79, in __getitem__
    raise MultiValueDictKeyError(key)

在django中,不需要用json包加载请求体,您可以通过json键从请求中获取数据:

def my_view(request):
   sample_data = request.POST['sample_key']
   # statements
