1.1.django官網

https://www.djangoproject.com/

1.2.安裝

獲取最新的正式版本

pip install Django==3.0.6 -i https://pypi.tuna.tsinghua.edu.cn/simple

查看django版本

(base) C:\Users\toto>python -m django --version 3.0.6

1.3.查看django-admin所擁有的的命令

在Anaconda的shell命令窗口輸入：

$ django-admin.py （Linux下） (base) E:\workspace> django-admin （Windows下）

1.4.Windows下創建一個項目的方式

django-admin startproject testdj django-admin startproject HelloWorld django-admin startapp TestModel

1.5.啟動服務

(base) E:\workspace\HelloWorld>python manage.py runserver 0.0.0.0:9000

1.6.使用idea中的Django創建Django項目

如果在創建項目的時候，出現ssl相關的錯誤，可以下載OpenSSL進行安裝。下載地址：

如果在創建過程出現了如下錯誤：

解決辦法是進入：https://www.sqlite.org/download.html，下載：

另外：執行以下命令：

(base) C:\Users\toto>pip install pysqlite3

最后點擊Create，直接可以創建成功。界面如下：

在E:\workspace\issuepicclassifyweb\issuepicclassifyweb下創建views.py。并編寫如下內容：

# -*- coding: UTF-8 -*-from django.http import HttpResponse from django.shortcuts import render from django.views.decorators.http import require_http_methods,require_GET,require_POST from django.views.decorators.csrf import csrf_exempt import json#@require_POST @require_http_methods(['GET','POST']) @csrf_exempt def predictPicClassify(request):data= {'patient_name':'張三','age':'25','patient_id':'19000347',}return HttpResponse(json.dumps(data,ensure_ascii=False), content_type='application/json,charset=utf-8')

修改E:\workspace\issuepicclassifyweb\issuepicclassifyweb\urls.py

from django.urls import path from . import viewsurlpatterns = [path('issuepicclassify/', views.predictPicClassify), ]

然后在terminal中執行以下命令：

(base) E:\workspace\issuepicclassifyweb>python manage.py runserver 0.0.0.0:8000

然后在瀏覽器上訪問：http://localhost:8000/issuepicclassify/。結果如下：
