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。
