沙箱環境跟真實環境是分開的，項目上線時必須切換對應的配置服務器地址和開發者ID和密鑰。ios

開發支付功能
cd luffy/apps
python ../../manage.py startapp payments
配置祕鑰
1. 生成應用的私鑰和公鑰
json
axios
2. 保存應用私鑰文件
在payments應用中新建keys目錄，用來保存祕鑰文件。
將應用私鑰文件app_private_key.pem複製到payment/keys目錄下。
-----BEGIN RSA PRIVATE KEY-----
私鑰
-----END RSA PRIVATE KEY-----
3. 保存支付寶公鑰
在payment/keys目錄下新建alipay_public_key.pem文件，用於保存支付寶的公鑰文件。
將支付寶的公鑰內容複製到alipay_public_key.pem文件中
-----BEGIN PUBLIC KEY-----
公鑰
-----END PUBLIC KEY-----
4. 使用支付寶的sdk開發支付接口
SDK：https://docs.open.alipay.com/270/106291/
python版本的支付寶SDK文檔：https://github.com/fzlee/alipay/blob/master/README.zh-hans.md
安裝命令：
pip install python-alipay-sdk --upgrade
流程思路:
1.在order頁面用戶點擊支付寶支付時,前端須要向後端發送帶有訂單ID值得請求,讓後端經過上面安裝的支付寶sdk構造連接返回來,而後再接受響應的地方跳轉到支付寶提供的支付界面
<template> ..... <el-col :span="4" class="cart-pay" ><span @click="payhandler" >支付寶支付</span></el-col> .... </template> <script> export default { name:"Order", methods:{ payhandler(){ // 判斷用戶是否已經登錄了。 if( !this.token){ this.$router.push("/login"); } let _this = this; // 發起請求獲取購物車中的商品信息 _this.$axios.get("http://127.0.0.1:8000/pay/"+_this.order_id,{ headers: { 'Authorization': 'JWT ' + _this.token }, responseType: 'json', }).then(response=>{ console.log("response.data",response.data.url) //跳轉頁面到支付界面 window.location.href=response.data.url; }) } }, } </script>
2.後端接收到前端支付的請求,實現發起支付接口(生成支付連接返回),其中有許多配置項都須要注意,詳細可參考開發者文檔
class PaymentAPIView(APIView): """支付寶""" permission_classes = (IsAuthenticated,) def get(self, request, order_id): """獲取支付連接""" # 判斷訂單信息是否正確 try: order = Order.objects.get(order_id=order_id, user=request.user, order_status=0,) except Order.DoesNotExist: return Response({'message': '訂單信息有誤'}, status=status.HTTP_400_BAD_REQUEST) # 構造支付寶支付連接地址 alipay = AliPay( appid=settings.ALIPAY_APPID, app_notify_url=None, # 默認回調url app_private_key_path=os.path.join(os.path.dirname(os.path.abspath(__file__)), "keys/app_private_key.pem"), alipay_public_key_path=os.path.join(os.path.dirname(os.path.abspath(__file__)), "keys/alipay_public_key.pem"), # 支付寶的公鑰，驗證支付寶回傳消息使用，不是你本身的公鑰, sign_type="RSA2", # RSA 或者 RSA2 debug=settings.ALIPAY_DEBUG ) order_string = alipay.api_alipay_trade_page_pay( out_trade_no=order.id, total_amount=str(order.total_price), subject=order.order_desc, return_url="http://127.0.0.1:8080/pay_success", ) alipay_url = settings.ALIPAY_URL + "?" + order_string return Response({'alipay_url': alipay_url}, status=status.HTTP_201_CREATED)
# 支付寶 ALIPAY_APP_ID="2016091600523592" # 應用ID APLIPAY_APP_NOTIFY_URL = None # 應用回調地址[支付成功之後,支付寶返回結果到哪個地址下面] APP_PRIVATE_KEY_PATH = os.path.join(BASE_DIR,"luffy/apps/payments/keys/app_private_key.pem") ALIPAY_PUBLIC_KEY_PATH = os.path.join(BASE_DIR,"luffy/apps/payments/keys/alipay_public_key.pem") ALIPAY_DEBUG = True # APIPAY_GATEWAY="https://openapi.alipay.com/gateway.do" #上線使用 APIPAY_GATEWAY="https://openapi.alipaydev.com/gateway.do" #開發環境使用 ALIPAY_RETURN_URL = "http://127.0.0.1:8080/success" ALIPAY_NOTIFY_URL = "http://127.0.0.1:8080/success"
3.當購買人支付成功後,支付寶會跳轉連接到以前咱們配置好的頁面中,("http://127.0.0.1:8080/success"),因此須要提早寫好購買成功的界面,並在該頁面向後端發送購買成功的信息,此時後端會驗證更新訂單狀態,包括寫入支付日期,以及訂單狀態的更改等
success.vue 前端發起請求頁面:..
<template> ..... </template> <script> import Header from "./common/Header" import Footer from "./common/Footer" export default{ created(){ // 頁面刷新時,最開始時候要把支付寶服務器的返回get參數結果提交給後端 // 後端須要根據這結果修改訂單的狀態 this.$axios.get("http://127.0.0.1:8000/pay/result"+location.search,{ headers: { 'Authorization': 'JWT ' + this.token }, responseType: 'json', }).then(response=>{ this.result = response.data }).catch(error=>{ console.log(error.response); }) </script>
注意,此時後端發送的數據,必需要攜帶支付寶在表頭返回的數據,以用於後端驗證
支付寶會返回的參數以下列表：(前面是域名,後面纔是參數)
http://127.0.0.1:8080/success?charset=utf-8& out_trade_no=2019040217080000000010976& method=alipay.trade.page.pay.return& total_amount=1206.44& sign=XKJG5826fH%2F9%2B3jCWw2ODjlc%2FuGLfqmr5RnimSAqrh%2B5bFkWcbLDh5V6VYtMqCpwnYp3FuGPqEeUeRO6WK62Qz0Q5nQGOA394IdxPfTOzry7PXuwYf41PCbDq53yg7vCYrobz4Tt8uajeADJLJwIsL%2F%2B88vbDEISUDUujL4442kl3oLh3EDD8DxZc2LLsv1Z%2FEFGJMfcTA47A4T7qmjB%2BbLKJetZZBISdt9RDL0q8A%2BAfb8B3Ux1nq%2F0EiNGiwIlWC1pvUCHK2UXMJW3kmgU9P9Zoujrj4ER28oieQt6Rt4gQXeah5uYtAMkftWfZpiyu%2FjUkr6iRx%2B4mP5IFz4Uew%3D%3D& trade_no=2019040222001439881000005802& auth_app_id=2016091600523592& version=1.0& app_id=2016091600523592& sign_type=RSA2& seller_id=2088102175868026& timestamp=2019-04-02%2017%3A13%3A15
4.後端對發送過來的請求,會進行訂單是否成功的驗證,若驗證成功,則會修改相應的訂單狀態,並返回相應的訂單的信息內容,以供前端渲染數據
後端代碼以下:
1 class PaymentAPIView(APIView): 2 ....... 3 4 5 class PayResultAPIView(APIView): 6 def get(self,request): 7 """處理get返回結果的數據""" 8 # 接受數據 9 data = request.query_params.dict() 10 print(data) 11 # sign 不能參與簽名驗證 12 signature = data.pop("sign") 13 # print(json.dumps(data)) 14 # print(signature) 15 alipay = AliPay( 16 appid=settings.ALIPAY_APP_ID, 17 app_notify_url=None, # 默認回調url 18 # 應用私鑰 19 app_private_key_path=settings.APP_PRIVATE_KEY_PATH, 20 # 支付寶的公鑰, 21 alipay_public_key_path=settings.ALIPAY_PUBLIC_KEY_PATH, 22 sign_type="RSA2", # 密碼加密的算法 23 # 開發時屬於調試模式 24 debug = settings.ALIPAY_DEBUG # 默認False 25 ) 26 27 # verify驗證支付結果,布爾值 28 success = alipay.verify(data, signature) 29 30 if success: 31 # 支付成功 32 order = Order.objects.get(order_number=data.get("out_trade_no")) 33 order.order_status = 1 # 修改訂單狀態 34 order.pay_time = datetime.now().strftime("%Y-%m-%d %H:%M:%S") 35 order.save() 36 37 38 return Response({ 39 "length":order.order_course.count(), 40 "paytime": order.pay_time, 41 "price":order.total_price, 42 "info":order.order_desc, 43 },status=status.HTTP_200_OK) 44 45 return Response({"message":"訂單沒有變化"}) 46 def post(self,request): 47 """提供給支付寶發送post數據""" 48 # 參考上面的代碼實現 49 # 接受數據 50 data = request.data.dict() 51 52 # sign 不能參與簽名驗證 53 signature = data.pop("sign") 54 # print(json.dumps(data)) 55 # print(signature) 56 alipay = AliPay( 57 appid=settings.ALIPAY_APP_ID, 58 app_notify_url=None, # 默認回調url 59 # 應用私鑰 60 app_private_key_path=settings.APP_PRIVATE_KEY_PATH, 61 # 支付寶的公鑰, 62 alipay_public_key_path=settings.ALIPAY_PUBLIC_KEY_PATH, 63 sign_type="RSA2", # 密碼加密的算法 64 # 開發時屬於調試模式 65 debug=settings.ALIPAY_DEBUG # 默認False 66 ) 67 68 # verify驗證支付結果,布爾值 69 success = alipay.verify(data, signature) 70 71 if success: 72 # 支付成功 73 order = Order.objects.get(order_number=data.get("out_trade_no")) 74 order.order_status = 1 # 修改訂單狀態 75 order.pay_time = datetime.now().strftime("%Y-%m-%d %H:%M:%S") 76 order.save() 77 78 return Response({ 79 "length": order.order_course.count(), 80 "paytime": order.pay_time, 81 "price": order.total_price, 82 "info": order.order_desc, 83 }, status=status.HTTP_200_OK) 84 85 return Response({"message": "訂單沒有變化"})
