Django对接支付宝APP支付问题

因为python没有集成支付宝的sdk,安装第三方的包 python-alipay-sdk 1.79

pip install  python-alipay-sdk==1.79

具体操作参考

实现过程

生成自己的公钥和私钥

openssl
OpenSSL> genrsa -out app_private_key.pem   2048  # 私钥
OpenSSL> rsa -in app_private_key.pem -pubout -out app_public_key.pem # 导出公钥
OpenSSL> exit

在支付宝上下载的公钥是一个字符串，你需要在文本的首尾添加标记位 (-----BEGIN PUBLIC KEY-----和-----END PUBLIC KEY-----) 才能正常使用证书的格式你可以参考这里

views.py

from alipay import AliPay
from django.conf import settings


notify_url = "https://xxxxx:8003/api/aliapy_back_url/" # 支付成功回掉的地址，在支付宝中设置
@csrf_exempt
def ali():
    # 设置自己的私钥，将自己的公钥放在支付宝上
    merchant_private_key_path = settings.BASE_DIR + '/live_api/static/keys/pri/pri.pem' #设置公钥和私钥的地址，文件上下两行begin和end是必须的，公钥就放在第二行。
    #设置支付宝公钥，我用的是sha1加密方式的pem文件
    alipay_public_key_path = settings.BASE_DIR + '/live_api/static/keys/pub/pub.pem'
    app_private_key_string = open(merchant_private_key_path).read()
    alipay_public_key_string = open(alipay_public_key_path).read()
    app_id = "" #复制来自支付宝生成的id

    alipay = AliPay(
        appid=app_id,
        app_notify_url=notify_url,  # 默认回调url
        app_private_key_string=app_private_key_string,
        alipay_public_key_string=alipay_public_key_string,  # 支付宝的公钥，验证支付宝回传消息使用，不是你自己的公钥,
        sign_type="RSA",  # RSA 或者 RSA2 
        debug = False  # 默认False
    )
    return alipay

充值生成订单
@csrf_exempt
def recharge(request):
    alipay = ali()
    ret = {
	    'code': 200,
            'msg': '请求成功!'
	    'order_string'
	}
    try:
        info = INFO(request)
        info.checkPostEmpty('user_id', 'money')
	user_id = request.POST.get('user_id')
	money = request.POST.get( 'money')
	# 生成订单
        order_string = alipay.api_alipay_trade_app_pay(
                out_trade_no="LB" + str(int(round(time.time()))),  # 商户订单号
                total_amount=money,
                subject="liuhuabi",  # 商品简单描述
                notify_url=notify_url # 可选, 不填则使用默认notify url
            )

        ret.code = 200
        print order_string
        ret.order_string = order_string
        ret.msg = "请求成功!"
    except Exception, e:
        ret.code = 1010
        ret.msg = str(e)
        print(str(e))
    return HttpResponse(ret.toJson()) 返回订单的生成的订单码
