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。
