django API 中介面的互相呼叫例項

我就廢話不多說了,還是直接上程式碼吧!

 url = "http://%s:%s/api-token-auth/" % (ip,port)
 query_args = {
  "username": username,"password": password
 }
 resp = requests.post(url=url,data=query_args)
 token = json.loads(resp.text)["token"]
 headers = {"Authorization": "JWT" + " " + token}  # 拿到token,拼成headers


 post_url = "http://%s:%s/message/message-level-two/"% (ip,port)
 data = {
  "app": app,"url": url,"message_id": message_id,"head": head,"title": title,"userprofile_id_list": userprofile_id_list
 }
 headers = self.headers
 requests.post(url=post_url,data=data,headers=headers)

獲取當前請求的ip和埠

 host_ip,host_port = self.request.META.get("HTTP_HOST").split(':')[0],\
        self.request.META.get("HTTP_HOST").split(':')[1]

常見的請求頭如下:

CONTENT_LENGTH – The length of the request body (as a string).
CONTENT_TYPE – The MIME type of the request body.
HTTP_ACCEPT – Acceptable content types for the response.

HTTP_ACCEPT_ENCODING – Acceptable encodings for the response.
HTTP_ACCEPT_LANGUAGE – Acceptable languages for the response.
HTTP_HOST – The HTTP Host header sent by the client.
HTTP_REFERER – The referring page,if any.
HTTP_USER_AGENT – The client's user-agent string.
QUERY_STRING – The query string,as a single (unparsed) string.
REMOTE_ADDR – The IP address of the client.
REMOTE_HOST – The hostname of the client.
REMOTE_USER – The user authenticated by the Web server,if any.
REQUEST_METHOD – A string such as "GET" or "POST".
SERVER_NAME – The hostname of the server.
SERVER_PORT – The port of the server (as a string).

獲取請求頭內容的用META

示例:

def index(request):
 ip = request.META.get("REMOTE_ADDR")
 return HttpResponse("你的ip地址是%s"%ip)

http://10.254.30.27/1
self.kwargs[‘pk'] # 可以拿到後邊的 1

補充知識:django 使用requests請求相關介面

1、如果是get請求介面,並且需要帶相關引數的話,可以借鑑下面的程式碼:

import requests
 
from django.http import JsonResponse
 
def get_info(request):
 url = 'http://www.baidu.com'
 params = {'id': 1,'user': 'lin'}
 response = requests.get(url=url,params=params)
 return JsonResponse(response.text,safe=False)

這樣將會返回一串json的字串資料。

2、如果是post請求介面,並且需要帶相關引數的話,可以借鑑下面的程式碼:

import requests
 
from json import dumps
from django.http import JsonResponse
 
def get_info(request):
 url = 'http://www.baidu.com'
 data = {'id': 1,'user': 'lin'}
 response = requests.post(url=url,data=dumps(data))
 return JsonResponse(response.text,safe=False)

注:

(1)、其中必須注意的為data這個引數,必須要用dumps(data)轉換一下,不然會報錯,response狀態碼為400,bad request error 400 while using python requests.post function。

(2)、如果需要在post請求底下加相關請求頭的話,可以借鑑下面的程式碼:

import requests
 
from json import dumps
from django.http import JsonResponse
 
def get_info(request):
 url = 'http://www.baidu.com'
 data = {'id': 1,'user': 'lin'}
 headers = {'content-Type': 'application/json','Accept': '*/*'}
 response = requests.post(url=url,data=dumps(data),headers=headers)
 return JsonResponse(response.text,safe=False)

這裡如果response的狀態碼報415錯誤的話,即HTTP請求415錯誤 – 不支援的媒體型別(Unsupported media type),這就是content-Type可能寫錯了,就要注意一下了,因為通常介面會封裝一些引數到請求頭底下。
