django API 中接口的互相调用实例

我就废话不多说了,还是直接上代码吧!

 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)

获取当前请求的ip和端口

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

常见的请求头如下:

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).

获取请求头内容的用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'] # 可以拿到后边的 1

补充知识:django 使用requests请求相关接口

1、如果是get请求接口,并且需要带相关参数的话,可以借鉴下面的代码:

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)

这样将会返回一串json的字符串数据。

2、如果是post请求接口,并且需要带相关参数的话,可以借鉴下面的代码:

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)、其中必须注意的为data这个参数,必须要用dumps(data)转换一下,不然会报错,response状态码为400,bad request error 400 while using python requests.post function。

(2)、如果需要在post请求底下加相关请求头的话,可以借鉴下面的代码:

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)

这里如果response的状态码报415错误的话,即HTTP请求415错误 ? 不支持的媒体类型(Unsupported media type),这就是content-Type可能写错了,就要注意一下了,因为通常接口会封装一些参数到请求头底下。

以上这篇django API 中接口的互相调用实例就是小编分享给大家的全部内容了,希望能给大家一个参考,也希望大家多多支持自学编程网。
