篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了生成微博授权URL及回调地址相关的知识,希望对你有一定的参考价值。
1.创建apps/oauth模块进行oauth认证
‘‘‘2.1 在apps文件夹下新建应用: oauth‘‘‘
cd syl/apps
python ../manage.py startapp oauth # 切换到apps文件夹下执行创建命令
‘‘‘2.2 添加子路由: oauth/urls.py‘‘‘
from django.urls import path
from . import views
urlpatterns = [
]
‘‘‘2.3 在syl/settings.py中添加应用‘‘‘
INSTALLED_APPS = [
‘oauth.apps.OauthConfig‘,
]
‘‘‘2.4 在syl/urls.py主路由中添加‘‘‘
urlpatterns = [
path(‘oauth/‘, include(‘oauth.urls‘)),
]
2.生成微博授权URL接口
1.1 添加子路由: oauth/urls.py
urlpatterns = [
path(‘weibo/‘, views.WeiboUrl.as_view()), # /oauth/weibo/ 返回微博登录地址
]
1.2 syl/settings.py 中配微博地址
WEIBO_CLIENT_ID = ‘3516473472‘
WEIBO_REDIRECT_URL = ‘http://127.0.0.1:8888/oauth/callback/‘
1.3 视图函数: oauth/views.py
from rest_framework.permissions import AllowAny
from rest_framework.response import Response
from rest_framework.views import APIView
from urllib.parse import urlencode
# 生成前端跳转到微博扫码页面的url
class WeiboUrl(APIView):
‘‘‘
生成微博的登陆页面路由地址
https://api.weibo.com/oauth2/authorize? # 微博oauth认证地址
client_id=4152203033& # 注册开发者id
response_type=code&
redirect_uri=http://127.0.0.1:8888/oauth/callback/ # 获取code后将code回
调给后端地址
‘‘‘
# 自定义权限类
permission_classes = (AllowAny,)
def post(self, request):
url = ‘https://api.weibo.com/oauth2/authorize?‘ # 微博授权的url地址
data = {
‘client_id‘: ‘3847987228‘, #settings.WEIBO_CLIENT_ID
‘response_type‘: ‘code‘,
‘redirect_uri‘: ‘http://127.0.0.1:8888/oauth/callback/‘, # VUE的回调,微博后台授权的回调地址
}
weibo_url = url + urlencode(data)# https://api.weibo.com/oauth2/authorize?
# client_id = 4152203033 & response_type = code & redirect_uri = http: // 127.0.0.1: 8000 / api / weibo_back /
# return Response({‘weibo_url‘: weibo_url})
return Response({‘code‘: ‘0‘, ‘msg‘: ‘成功‘, ‘data‘: {‘url‘: weibo_url}})
3.测试生成微博售前URL接口
- 测试接口获取新浪微博地址
http://192.168.56.100:8888/oauth/weibo/
1.在Vue页面加载时动态发送请求获取微博授权url
1.1 在 componentscommonlab_header.vue 中写oauth动态获取微博授权URL
// 获取微博登录地址
oauth() {
// 从后端获取 微博登录地址
oauth_post().then((resp) => {
console.log(resp)
//{‘code‘: ‘0‘, ‘msg‘: ‘成功‘, ‘data‘: {‘url‘: url}}
let url = resp.data.url;
this.weibo_url = url;
})
},
1.2 在vue的mounted函数中调用获取微博授权url函数
mounted() {
this.oauth()
},
1.3 点击"登录"弹出的form表单中加入url
<form
action="/login"
method="post"
>
<div class="form-group widget-signin">
<a :href="weibo_url"><i class="fa fa-weibo"></i></a>
</div>
</form>
1.微博回调接口
1.1 oauth/urls.py 中添加路由
urlpatterns = [
path(‘weibo/callback/‘, views.OauthWeiboCallback.as_view()), #/oauth/weibo/callback/
]
1.2 oauth/views.py 中添加试图函数
http://192.168.56.100:8888/oauth/weibo/callback/
from .models import OauthUser
from rest_framework_jwt.serializers import jwt_payload_handler,
jwt_encode_handler
from user.utils import jwt_response_payload_handler
# 通过vue前端传入的code,微博身份验证
class OauthWeiboCallback(APIView):
# 自定义权限类
permission_classes = (AllowAny,)
def post(self, request):
# 接收vue端传过来的code(微博的用户code)
# 1.使用微博用户code+微博开发者账号信息换取微博的认证access_token
code = request.data.get(‘code‘)
data = {
‘client_id‘: ‘3847987228‘,
‘client_secret‘: ‘538c1fb220cdad5cd35bafe26e80ec03‘,
‘grant_type‘: ‘authorization_code‘,
‘code‘: code,
‘redirect_uri‘: ‘http://127.0.0.1:8888/oauth/callback/‘,
}
url = ‘https://api.weibo.com/oauth2/access_token‘
data = requests.post(url=url, data=data).json() # 拿取请求的返回结果
# access_token = data.get(‘uid‘) # 获取到的微博token
weibo_uid = data.get(‘uid‘) # 获取到少码用户的id
# 2. 根据uid 查询绑定情况
try:
oauth_user = OauthUser.objects.get(uid=weibo_uid, oauth_type=‘1‘)
except Exception as e:
oauth_user = None
# 返回动作, 登录成功/需要绑定用户 type 0 登录成功, 1, 授权成功, 需要绑定
if oauth_user:
# 4. 如果绑定了, 返回token, 登录成功
user = oauth_user.user
payload = jwt_payload_handler(user)
token = jwt_encode_handler(payload)
# jwt_response_payload_handler为user模块定义的jwt返回的信息
data = jwt_response_payload_handler(token, user)
#1.3 oauth/models.py 中添加用户绑定模型
#1.4 迁移数据库
data[‘type‘] = ‘0‘ # 指定为登录成功
return Response({‘code‘: 0, ‘msg‘: ‘登录成功‘, ‘data‘: data})
else:
# 5. 如果没绑定, 返回标志, 让前端跳转到绑定页面
return Response({‘code‘: 0, ‘msg‘: ‘授权成功‘, ‘data‘: {‘type‘: ‘1‘,‘uid‘: weibo_uid}})
1.3 oauth/models.py 中添加用户绑定模型
# 把三方的用户信息,和本地的用户信息进行绑定
class OauthUser(models.Model):
OAUTHTYPE = (
(‘1‘, ‘weibo‘),
(‘2‘, ‘weixin‘),
)
uid = models.CharField(‘三方用户id‘, max_length=64)
# 三方用户id
user = models.ForeignKey(‘user.User‘, on_delete=models.CASCADE)
# 本地用户外键,关联User表
oauth_type = models.CharField(‘认证类型‘, max_length=10, choices=OAUTHTYPE)
1.4 迁移数据库
python manager.py makemigrations
python manager.py migrate
1.vue微博回调空页面
- 注:微博回调空页面为: http://127.0.0.1:8888/oauth/callback/
1.1 页面路径 componentsoauth.vue
<template>
<div>
<p>跳转中....</p>
</div>
</template>
<script>
import { oauth_callback_post, oauth_binduser_post, user_count } from ‘./axios_api/api‘
export default {
data() {
return {
visiable: false, // 绑定用户窗口
uid: ‘‘, // weibo_uid
username: ‘‘,
password: ‘‘,
username_message: ‘‘,
username_error: false
}
},
mounted() {
this.getCode()
},
methods: {
// 2.判断用户名是否合法
check_username() {
console.log(‘判断用户名‘)
console.log(this.username == ‘‘)
var reg = new RegExp(/^[a-zA-Z0-9_-]{3,16}$/); //字符串正则表达式 4到14位(字母,数字,下划线,减号)
if (this.username == ‘‘) {
this.username_message = ‘用户名不能为空‘
this.username_error = true
return false
}
if (!reg.test(this.username)) {
this.username_message = ‘用户名格式不正确‘
this.username_error = true
return false
} else {
// 去后端检查用户名使用数量
user_count({ type: ‘username‘, data: this.username }).then((res) => {
console.log(res)

this.username_message = ‘用户名已存在, 请输入密码‘
this.username_error = false
} else {
this.username_message = ‘用户名可用, 将创建新用户,请输入密码‘
this.username_error = false
}
})
}
},
// 1.1当页面被挂载时就自动调用,通过url获取微博的code,发送code给django端
// 1.2 如果已经绑定,返回 type=‘0‘,登录成功,直接跳转到首页
// 1.3 如果未绑定,返回type=‘1‘,显示绑定用户的页面
getCode() {
// 获取url中的code 信息,code信息是微博端返回的

console.log(this.$route.query)

let params = { code: code }
oauth_callback_post(params).then((resp) => {
console.log(resp)
// code: 0
// msg: "授权成功"
// data: {type: "1", uid: "7410919278"}
// 如果type=0代表以前已经绑定过,直接登录成功
if (resp.data.type == ‘0‘) {
// code: 0

let res = resp.data
localStorage.setItem(‘username‘, res.username)
// localStorage.setItem(‘img‘, res.img)
localStorage.setItem(‘token‘, res.token)
localStorage.setItem(‘uid‘, res.id)
this.login_username = res.username
this.opened = false

}
// 如果用户·没有绑定过,显示绑定页面
if (resp.data.type == ‘1‘) {
this.visiable = true
this.uid = resp.data.uid
}
})
},
// 3.绑定微博用户与实验楼本地用户
bindUser() {
if(this.username_error){
return
}
// 发送 用户名, 密码, weibo_uid 到后端接口, 进行绑定
let params = { username: this.username, password: this.password, weibo_uid: this.uid }
oauth_binduser_post(params).then((resp) => {
console.log(resp)
let res = resp.data
localStorage.setItem(‘username‘, res.username)

localStorage.setItem(‘token‘, res.token)

this.opened = false
// alert(res.message)
this.$router.push(‘/‘)
})
}
}
