Django不接受来自python请求的数据。patch（）

我试图通过http

PATCH

请求将数据从一个运行python的服务发送到另一个运行Django的使用python的服务

SomeAccount

有一个字段

appUserId

，现在是

-1

以下是知道应用程序用户id的某个发件人.py（

=77

，例如）：

当我在

GET/someaccounts/1

检查项目的值时，它仍然具有

appUserId=-1

在调试时，在Django中我得到了请求，但没有任何数据——它只是一个空的dict

以下是我在Django看到的情况：

mysite/myapp/url.py：

from django.conf.urls import include, url
from rest_framework import routers
from . import views

router = routers.DefaultRouter()

router.register(r'someaccount', views.SomeAccountViewSet)
# ...
urlpatterns = [
    url(r'^', include(router.urls)),
    # ...
]

from django.db import models
# ...
class SomeAccount(models.Model):
    """

    """
    # ...
    appUserId = models.BigIntegerField(blank=True, null=True)

class SomeAccountViewSet(viewsets.ModelViewSet):
    """

    queryset = SomeAccount.objects.all()
    serializer_class = SomeAccountSerializer

from models import SomeAccount

    id = serializers.ReadOnlyField()

    class Meta:
        model = SomeAccount
        fields = ('url', 'id', 'appUserId')
        depth = 3
        partial = True

    def update(self, someAccount, account_data):
        if 'appUserId' in account_data:
            someAccount.appUserId = account_data.pop('appUserId')
        someAccount.save()
        return someAccount

        partial = True

    def update(self, someAccount, account_data):
        if 'appUserId' in account_data:
            someAccount.appUserId = account_data.pop('appUserId')
        someAccount.save()
        return someAccount

            someAccount.appUserId = account_data.pop('appUserId')
        someAccount.save()
        return someAccount

在

SomeAccountSerializer

中，当对传入请求进行调试时，我得到以下值：

• account\u数据：{}

• 初始数据：

• someAccount:{'appUserId'：-1，'id'：1}

我试图通过邮递员谷歌浏览器插件发送相同的值，结果成功了

我还尝试设置

内容类型

标题：

使用

应用程序/x-www-form-urlencoded

：

requests.patch(
    url, data=data, auth=auth,
    headers={'content-type': 'application/x-www-form-urlencoded'}
)

使用

申请/表格数据

：

requests.patch(
    url, data=data, auth=auth,
    headers={'content-type': 'application/form-data'}
)

使用

应用程序/json

：

requests.patch(
    url, json=json.dumps(data), auth=auth,
    headers={'content-type': 'application/json'}
)

没有成功

python请求正在正确发送请求。问题可能在于Django是如何处理的。

您应该检查您的网络流量，以确保问题出现在哪里。如果我使用

import requests

app_user_id = 7
auth = ('someusrname', 'somepwd')
data = {'appUserId': app_user_id}
url = 'http://localhost:8000/someaccounts/1'

r = requests.put(url, data=data, auth=auth)
print r.status_code

然后用netcat（nc-l 8000）打开一个本地套接字。我正在获取编码的数据表单：

PUT /someaccounts/1 HTTP/1.1
Host: localhost:8000
Content-Length: 11
Accept-Encoding: gzip, deflate
Accept: */*
User-Agent: python-requests/2.8.1
Connection: keep-alive
Content-Type: application/x-www-form-urlencoded
Authorization: Basic c29tZXVzcm5hbWU6c29tZXB3ZA==

appUserId=7

只是遇到了同样的问题。缺少URL上的尾部斜杠。当Django用尾随的斜杠重定向到URL时，它似乎删除了补丁的有效负载。

OK，这里也一样。它似乎仍在发送数据。（仅限diff:

用户代理：python请求/2.6.0 CPython/2.7.10 Darwin/14.5.0

）检查请求的响应正文，这可能对问题有一些了解。这也有帮助，谢谢！结果在服务器端和URL上出现了一些错误（我可能在URL字符串的末尾缺少了一个

/

，所以应该是

GET/someaccounts/1/

）
