Python django中的json解析

我构建了一个webhook来接收json

POST

。但是，我从json解码器收到一个错误。这是webhook中的view.py文件

import json
from django.shortcuts import render
from django.views.decorators.http import require_POST
from django.views.decorators.csrf import csrf_exempt
from django.http import HttpResponse
from .models import UserText

# Create your views here.
@csrf_exempt
@require_POST
def webhookmb(request):
    usrtxt = json.loads(request.body)

    UserText.objects.create(
        id = usrtxt['id'],
        recipient = usrtxt['recipient'],
        originator = usrtxt['originator'],
        body = usrtxt['body'],
        createdDatetime = usrtxt['createdDatetime'],
    )

    # redirect to API.AI
    # TODO


    return HttpResponse(200)

这就是我收到的错误

我不太确定如何解决这个问题，我已经解决了很多问题，但是我被困在如何解决

json.decoder.JSONDecodeError:期望值：第1行第1列（char 0）

任何反馈都会令人惊讶。谢谢

这可能是由于编码不匹配

因为您没有提供json本身

试试这个

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

可能是客户端没有向服务器发送正确的json吗？这是什么版本的django？也许您可以尝试打印request.POST、request.body等以查看发送的数据？类似的问题可能会有所帮助：。
