CMDB之客户端实现

Request模块收发json 数据

---

requests.get.text

返回文本字符串

api

def api(request):
    if request.method == 'POST':
        print(request.POST)
        k1, k2 = request.POST.get('k1')[0], request.POST.get('k2')[0]
        return JsonResponse({'status': 200, 'msg': '接收到了'}, json_dumps_params={'ensure_ascii': False})
    if request.method == 'GET':
        host_list = ['xmaster', 'xminion']
        return JsonResponse(host_list, safe=False)  # JsonResponse如果返回列表, 需要加上safe=False

客户端

url = 'http://127.0.0.1:8000/api/'
response = requests.get(url=url)  # ["xmaster", "xminion"] <class 'str'>
print(response.text, type(response.text))

输出结果

["xmaster", "xminion"] <class 'str'>

requests.get.json

返回原本的数据类型, 比如说在服务端序列化前的数据类型是列表, 则最后返回列表

api

def api(request):
    if request.method == 'POST':
        print(request.POST)
        k1, k2 = request.POST.get('k1')[0], request.POST.get('k2')[0]
        return JsonResponse({'status': 200, 'msg': '接收到了'}, json_dumps_params={'ensure_ascii': False})
    if request.method == 'GET':
        host_list = ['xmaster', 'xminion']
        return JsonResponse(host_list, safe=False)  # JsonResponse如果返回列表, 需要加上safe=False

客户端

import requests

url = 'http://127.0.0.1:8000/api/'
response = requests.get(url=url)

print(response.json(), type(response.json()))

输出结果

['xmaster', 'xminion'] <class 'list'>

requests.post

客户端发送字典套字典数据的时候, 服务端最后接收的数据是外层的字典,

request.POST内部构成为 {外层字典的key: 内层字典的key}

request.body内部构成为 b'外层字典的key=内层字典的key&外层字典的key=内层字典的key'

注意:  只有request.body的数据构成是上面的格式, request.POST才能够接收到值

客户端

import requests

url = 'http://127.0.0.1:8000/api/'
info = {'k1': {'ens33': '网卡坏了'}, 'k2': {'ens22': '192.168.1.1'}}

response = requests.post(url=url, data=info)

api

from django.shortcuts import render, HttpResponse
from django.http import JsonResponse

# Create your views here.


def api(request):
    if request.method == 'POST':
        print(request.POST)  # <QueryDict: {'k1': ['ens33'], 'k2': ['ens22']}>
        print(request.body)  # b'k1=ens33&k2=ens22'
        return JsonResponse({'status': 200, 'msg': '接收到了'}, json_dumps_params={'ensure_ascii': False})
    if request.method == 'GET':
        host_list = ['xmaster', 'xminion']
        return JsonResponse(host_list, safe=False)

输出结果

<QueryDict: {'k1': ['ens33'], 'k2': ['ens22']}>
b'k1=ens33&k2=ens22'

解决方案:  使用json进行传递数据

方法1: 使用requests.post中的json选项来做

客户端

import requests

url = 'http://127.0.0.1:8000/api/'
info = {'k1': {'ens33': '网卡坏了'}, 'k2': {'ens22': '192.168.1.1'}}

response = requests.post(url=url, json=info)

api

from django.shortcuts import render, HttpResponse
from django.http import JsonResponse
import json


def api(request):
    if request.method == 'POST':
        print(request.POST)
        print(request.body)
        json_str = request.body.decode('utf-8')
        ret = json.loads(json_str)
        print(ret, type(ret))

        return JsonResponse({'status': 200, 'msg': '接收到了'}, json_dumps_params={'ensure_ascii': False})
    if request.method == 'GET':
        host_list = ['xmaster', 'xminion']
        return JsonResponse(host_list, safe=False)

方法2: 使用python的模块json来手动做

客户端

import requests
import json

url = 'http://127.0.0.1:8000/api/'
info = {'k1': {'ens33': '网卡坏了'}, 'k2': {'ens22': '192.168.1.1'}}

response = requests.post(url=url, data=json.dumps(info).encode('gbk'))

api

from django.shortcuts import render, HttpResponse
from django.http import JsonResponse
import json
# Create your views here.


def api(request):
    if request.method == 'POST':
        print(request.POST)
        print(request.body)
        json_str = request.body.decode('gbk')
        ret = json.loads(json_str)
        print(ret, type(ret))

        return JsonResponse({'status': 200, 'msg': '接收到了'}, json_dumps_params={'ensure_ascii': False})
    if request.method == 'GET':
        host_list = ['xmaster', 'xminion']
        return JsonResponse(host_list, safe=False)
