$Django 支付宝支付,微信服务号推送消息 (测试需要把应用程序部署到服务器上)
一 支付宝支付
大概
支付宝支付 正式环境:需要用营业执照去申请商户号,appid 测试环境:沙箱环境:https://openhome.alipay.com/platform/appDaily.htm?tab=info 支付宝提供接口:给商户使用,收钱 -Java,php,C#的demo,没有python的demo（事例） -git有人封装了 -需要安装模块:pip3 install pycryptodome -应用私钥---自己保存,一定不能丢 -应用公钥---给别人用 -支付宝公钥---支付宝用的 -生成公钥私钥:https://docs.open.alipay.com/291/105971 -把应用公钥配置在支付宝上:应用公钥,配置完成以后,支付宝自动生成一个支付宝公钥 -在程序中:配置应用私钥,支付宝公钥 -如果支付成功,支付宝会回调,但是如果你的服务器挂掉了怎么办? -支付宝24小时以内不定时再给你发,你修改掉订单状态即可 -支付成功,支付宝会有一个get回调,一个post回调:修改订单状态
沙箱测试流程(详情)
1.输入支付金额:在我们的网站往支付宝的网关https://openapi.alipaydev.com/gateway.do后面拼?账单(商品名,价格,我数据库生成的订单号等),回调的url等数据 
2.扫码支付：点击去支付来到了拼好的支付宝url 显示支付宝页面
3.支付完成:
4.回调之前拼接的url:支付宝向这个url 发起get请求:GET取数据【显示】支付成功失败和post请求:body(bytes格式)内取数据：状态/我数据库的订单号/支付宝的订单号等

2.keys:应用私钥，支付宝公钥
alipay_public_2048.txt -----BEGIN PUBLIC KEY----- # 加上这行 支付宝的公钥 -----END PUBLIC KEY----- # 同上 app_private_2048.txt -----BEGIN PUBLIC KEY----- #同上 应用的私钥 -----END PUBLIC KEY----- # 同上

二 微信服务号推送消息
大概
用什么推送 -邮件 -微信推送 -短信推送 微信推送 -公众号(群聊) -认证的公众号:需要营业执照,需要交钱,可以发多篇文章 -未认证的公众号:一天只能发一篇文章 -服务号(微信推送)(私聊) -需要申请,需要认证 -可以主动给单个用户推送消息 -能给推送的人,必须关注我的服务号 -沙箱环境:https://mp.weixin.qq.com/debug/cgi-bin/sandbox?t=sandbox/login
-企业号 -企业里用的: -你们所见的二维码:其实就是一个url地址 -咱们在前端通过url(https://open.weixin.qq.com/connect/oauth2.....)生成一个二维码
-注意*****修改:网页授权获取用户基本信息

沙箱测试流程(详情)
1.先去微信 https://mp.weixin.qq.com/debug/cgi-bin/sandbox?t=sandbox/login申请服务号:拿到appid,appsecret,服务号二维码
2.为了给微信用户推送信息(我们的服务器数据库要存上用户的微信号,如上图):先要关注服务号,然后诱导用户向我们拼好的一个微信url连接发请求
ret = {'code': 1000}
try:
access_url = "https://open.weixin.qq.com/connect/oauth2/authorize?appid={appid}&redirect_uri={redirect_uri}&response_type=code&scope=snsapi_userinfo&state={state}#wechat_redirect"
access_url = access_url.format(
# 商户的appid
appid=settings.WECHAT_CONFIG["app_id"], # 'wx6edde7a6a97e4fcd',
# 回调地址
redirect_uri=settings.WECHAT_CONFIG["redirect_uri"],
# 当前登录用户的唯一id
state=request.session['user_info']['uid'] # 为当前用户生成MD5值
)
ret['data'] = access_url
except Exception as e:
ret['code'] = 1001
ret['msg'] = str(e)
<script src="{% static "js/jquery.min.js" %}"></script>
{#qrcode 可以生成二维码 #}
<script src="{% static "js/jquery.qrcode.min.js" %}"></script>
<script src="{% static "js/qrcode.js" %}"></script>
<script>
//按钮点击事件
function getBindUserQcode() {
$.ajax({
url: '/bind_qcode/',
type: 'GET',
success: function (result) {
console.log(result);
//result.data 取出来的是什么?是后台生成的一个地址
//通过js生成一个二维码图片放到div中
$('#qrcode').empty().qrcode({text: result.data});
}
});
}
</script>
3.回调地址:微信根据回调地址再向我们服务器发请求,获得数据的同时我们服务器又向微信某个地址发送了一个request.get（爬虫请求）直接拿到了用户的微信号,更新到我们的数据库
#回调地址的路由url(r'^callback/$', views.callback) def callback(request): """ 用户在手机微信上扫码后，微信自动调用该方法。 用于获取扫码用户的唯一ID，以后用于给他推送消息。 :param request: :return: """ code = request.GET.get("code") # 用户md5值,用户唯一id state = request.GET.get("state") # 获取该用户openId(用户唯一，用于给用户发送消息) # request模块朝https://api.weixin.qq.com/sns/oauth2/access_token地址发get请求 res = requests.get( url="https://api.weixin.qq.com/sns/oauth2/access_token", params={ "appid": 'wx3e1f0883236623f9', "secret": '508ec4590702c76e6863be6df01ad95a', "code": code, "grant_type": 'authorization_code', } ).json() # res.data 是json格式 # res=json.loads(res.data) # res是一个字典 # 获取的到openid表示用户授权成功 openid = res.get("openid") if openid: models.UserInfo.objects.filter(uid=state).update(wx_id=openid) response = "<h1>授权成功 %s </h1>" % openid else: response = "<h1>用户扫码之后，手机上的提示</h1>" return HttpResponse(response)
4.最终:用户扫码后会得到回调地址的返回信息,例如 '授权成功'
5.我们定义了一个sendmsg(request)视图：1爬取当前用户的token，2服务器拿着token、用户微信号向微信发消息。这样用户就收到了服务号私发的信息
def sendmsg(request): def get_access_token(): """ 获取微信全局接口的凭证(默认有效期俩个小时) 如果不每天请求次数过多, 通过设置缓存即可 """ result = requests.get( url="https://api.weixin.qq.com/cgi-bin/token", params={ "grant_type": "client_credential", "appid": settings.WECHAT_CONFIG['app_id'], "secret": settings.WECHAT_CONFIG['appsecret'], } ).json() if result.get("access_token"): access_token = result.get('access_token') else: access_token = None return access_token access_token = get_access_token() openid = models.UserInfo.objects.get(id=1).wx_id def send_custom_msg(): body = { "touser": openid, "msgtype": "text", "text": { "content": 'lqz大帅哥' } } response = requests.post( url="https://api.weixin.qq.com/cgi-bin/message/custom/send", # 放到路径?后面的东西 params={ 'access_token': access_token }, # 这是post请求body体中的内容 data=bytes(json.dumps(body, ensure_ascii=False), encoding='utf-8') ) # 这里可根据回执code进行判定是否发送成功(也可以根据code根据错误信息) result = response.json() return result def send_template_msg(): """ 发送模版消息 """ res = requests.post( url="https://api.weixin.qq.com/cgi-bin/message/template/send", params={ 'access_token': access_token }, json={ "touser": openid, "template_id": 'IaSe9s0rukUfKy4ZCbP4p7Hqbgp1L4hG6_EGobO2gMg', "data": { "first": { "value": "lqz", "color": "#173177" }, "keyword1": { "value": "大帅哥", "color": "#173177" }, } } ) result = res.json() return result result = send_custom_msg() if result.get('errcode') == 0: return HttpResponse('发送成功') return HttpResponse('发送失败')
