在django python中为android提供web服务时遇到的麻烦

Question

I am new for Django1.10 Python

我必须为一个应用程序提供web服务。所以我在python的Django框架中创建了一个web服务。web服务在iOS中正常工作，但在处理android时遇到问题。在android中使用Volley库来处理web服务。

出现以下错误:-Error Code 500 Internal Server Error

所以无法通过android端发送数据…

对于Web服务，我使用以下代码:-

views.py

from django.http import HttpResponseRedirect, HttpResponse
from django.views.decorators import csrf
from django.views.decorators.csrf import csrf_protect, csrf_exempt
from django.db import IntegrityError, connection
from django.views.decorators.cache import cache_control
from django.core.files.images import get_image_dimensions                
import json
from json import loads, dump
from models import Gym

@csrf_exempt
def gym_register_web(request):
    data = json.loads(request.body)
    gN = str(data['gym_name'])
    gPh = str(data['gym_phone'])
    gE = str(data['gym_email'])
    gL = str(data['gym_landmark'])
    gAdd = str(data['gym_address'])
    exE = Gym.objects.filter(gym_email = gE)
    if exE:
        status = 'failed'
        msg = 'EmailId already exist'
        responseMsg = '{n "status" : "'+status+'",n "msg" : "'+msg+'"n}'
        return HttpResponse(responseMsg)
    else:
        gymI = Gym(gym_name = gN, gym_phone = gPh, gym_email = gE, gym_area = gL, gym_address = gAdd)
        gymI.save()
        data = Gym.objects.get(gym_email = gE)
        status = 'success'
        dataType = 'gym_id'
        val = str(data.gym_id)
        responseMsg = '{n "status" : "'+status+'",n "'+dataType+'" : "'+val+'"n}'
        return HttpResponse(responseMsg)

urls.py

from django.conf.urls import url, include
from . import views
from django.views.decorators.csrf import csrf_protect, csrf_exempt
admin.autodiscover()
urlpatterns=[
    url(r'^gymRegister/$', views.gym_register_web),
    ]+ static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

编辑:models.py

from django.db import models
from django.contrib import admin
class Gym(models.Model):
    gym_id = models.AutoField(primary_key = True)
    gym_name = models.CharField(max_length = 100, null=True,default = None )
    gym_email = models.CharField(max_length = 100, null=True,default = None )
    gym_phone = models.BigIntegerField(null=True,default = None )
    gym_area = models.TextField(max_length = 255, null=True,default = None )
    gym_address = models.TextField(max_length = 255, null=True,default = None )
    gym_latitude = models.CharField(max_length = 100, null=True,default = None )
    gym_longitude = models.CharField(max_length = 100, null=True,default = None )
    gym_status = models.IntegerField(null=True,default = None )
    gym_website = models.CharField(max_length = 255,null=True,default = None )
    gym_ladies_special = models.IntegerField(null=True,default = None )

我在Advance REST Client上测试了web服务，提供了所需的输出，我想再次提醒web服务是正常工作的iOS

那么，我应该在哪里改进我的代码…?

Thanks in Advance:)

编辑:

我的android开发人员试图以json对象方式发送数据

{ "key1"="val1", "key2"="val2"}

而不是以json array(key:value)方式发送

{
    "key1" : "val1",
    "key2" : "val2"
}

如何获取object格式发送的数据…

谢谢

1. 请确保在您的请求。Body '，你会得到一个合适的字典，里面有你在下面访问过的所有键。因为，如果你的'data'变量没有任何你在下面访问的键，它会引发keyerror，而你没有在你的代码中处理keyerror。

如果上面没有工作，然后显示你的models.py
