我正在創建一個 DRF 專案（僅限 API），其中登錄用戶可以指定他想要接收多少人隨機生成的憑據。
這是我的問題：我想從外部 API ( https://randomuser.me/api )獲取這些憑據。本網站會根據 url 的“結果”引數中指定的數量生成隨機用戶資料。前任。https://randomuser.me/api/?results=40
我的問題是：
我怎樣才能得到這些資料？我知道 JavaScript fetch() 方法可能很有用，但我實際上不知道如何將它與 Django Rest Framework 連接，然后對其進行操作。我想在用戶發送 POST 請求（僅指定要生成的用戶數）后向用戶顯示資料，并將結果保存在資料庫中，以便他稍后可以訪問它們（通過 GET 請求）。
如果您有任何想法或提示，我將不勝感激。
謝謝！
uj5u.com熱心網友回復：
以下是在 Django Rest Framework API 視圖中進行 API 呼叫的方法：
由于您想將外部 API 請求存盤在資料庫中。這是存盤用戶結果的模型示例。
模型.py
from django.conf import settings
class Credential(models.Models):
""" A user can have many generated credentials """
user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE)
value = models.CharField()
# Here we override the save method to avoid that each user request create new credentials on top of the existing one
def __str__(self):
return f"{self.user.username} - {self.value}"
視圖.py
from rest_framework.views import APIView
from rest_framework.response import Response
from rest_framework.permissions import IsAuthenticated
# Assume that you have installed requests: pip install requests
import requests
import json
class GenerateCredential(APIVIew):
""" This view make and external api call, save the result and return
the data generated as json object """
# Only authenticated user can make request on this view
permission_classes = (IsAuthenticated, )
def get(self, request, format=None):
# The url is like https://localhost:8000/api/?results=40
results = self.request.query_params.get('type')
response = {}
# Make an external api request ( use auth if authentication is required for the external API)
r = requests.get('https://randomuser.me/api/?results=40', auth=('user', 'pass'))
r_status = r.status_code
# If it is a success
if r_status = 200:
# convert the json result to python object
data = json.loads(r.json)
# Loop through the credentials and save them
# But it is good to avoid that each user request create new
# credentials on top of the existing one
# ( you can retrieve and delete the old one and save the news credentials )
for c in data:
credential = Credential(user = self.request.user, value=c)
credential.save()
response['status'] = 200
response['message'] = 'success'
response['credentials'] = data
else:
response['status'] = r.status_code
response['message'] = 'error'
response['credentials'] = {}
return Response(response)
class UserCredentials(APIView):
"""This view return the current authenticated user credentials """
permission_classes = (IsAuthenticated, )
def get(self, request, format=None):
current_user = self.request.user
credentials = Credential.objects.filter(user__id=current_user)
return Response(credentials)
注意：這些視圖假定user發出請求的人已通過身份驗證，更多資訊請點擊此處。因為我們需要用戶將檢索到的憑據保存在資料庫中。
網址.py
path('api/get_user_credentials/', views.UserCredentials.as_view()),
path('api/generate_credentials/', views.GenerateCredentials.as_view()),
.js
const url = "http://localhost:8000/api/generate_credentials/";
# const url = "http://localhost:8000/api/get_user_credentials/";
fetch(url)
.then((resp) => resp.json())
.then(function(data) {
console.log(data);
})
.catch(function(error) {
console.log(error);
});
