篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了支付宝支付功能接入(PC)相关的知识，希望对你有一定的参考价值。
在使用支付宝支付功能开发的阶段, 可以在沙箱环境下进行开发, 开发完成之后, 到线上再进行相关参数的替换即可
一. 登陆支付宝开放平台(https://open.alipay.com/platform/home.htm)
进入沙盒环境:
二. 设置加密方式 RSA 或者RSA2(推荐)
1. 生成RSA秘钥
可以使用支付宝提供的生成工具,具体说明见官网说明(https://opendocs.alipay.com/open/291/105971#LDsXr)
使用工具生成秘钥对
应用公钥: 需要将公钥填写到RSA2秘钥的设置中
应用私钥:是生成签名需要使用的
支付宝公钥: 在设置中点击查看支付宝公钥即可看到
2. 秘钥文件的修改
在秘钥文件中的内容的头部和尾部加上两行字符串, 注意所有的秘钥都要添加
-----BEGIN PRIVATE KEY-----
# 秘钥内容....
-----END PRIVATE KEY-----
这样可以方便的直接读取文件
三. 集成支付宝到项目
基本流程:
1. 接收商品名称信息、订单金额、订单号 2. 请求支付宝预付订单创建接口 3. 根据返回的URL返回给客户端 4. 用户支付 5. 用户支付完成之后，客户端会跳转到一个页面(服务器预置页面) 6. 用户支付完成之后，支付宝会调用回调(通知服务器)

)
备注: return_url 和 notify_url的区别
return_url:
如果设置了return_url，买家付款成功后会跳到return_url所在页面;
在这个页面可以展示给用户看，只有付款成功后才会跳转;
notify_url:
服务器后台通知,这个页面是程序后台运行的(买家和卖家都看不到);
买家付完款后,支付宝会调用notify_url这个页面所在的页面并把相应的参数传递到这个页面;
这个页面根据支付宝传递过来的参数修改网站订单的状态,更新完订单后需要在页面上;
打印出一个success给支付宝,如果反馈给支付宝的不是success,支付宝会继续调用这个页面;

注意点:
1. 测试的时候, 使用沙盒环境的支付宝
平台提供了沙盒账号,进行登陆与支付的时候使用
2. 参数说明
appid :2016091700535495(填写沙箱应用的appid) return_url: 对于PC网站支付的交易，在用户支付完成之后，支付宝会根据API中商户传入的return_url参数，通过GET请求的形式将部分支付结果参数通知到商户系统, 即同步返回地址，即支付成功跳转的页面url。同步通知详情 sign 签名字段，最重要的字段，后面会讲，详见签名 notify_url: 对于PC网站支付的交易，在用户支付完成之后，支付宝会根据API中商户传入的notify_url，通过POST请求的形式将支付结果作为参数通知到商户系统。异步通知详情 biz_content：除公共参数以外的其他必要参数 请求参数这些字段是最后放入公共字段里的biz_content，着重关注必填项
3. 生成签名与签名验证

遇到的问题:
1. 使用支付提供的验证签名工具一直都是签名失败, 后台发现是它工具版本问题, 导致不能验证成功
下载了衣蛾1.4版本就可以成功了

二、组成待验签串：
1.剔除空值参数：
【gmt_create=2020-03-25 10:59:32&charset=utf-8&gmt_payment=2020-03-25 10:59:38¬ify_time=2020-03-25 10:59:38&subject=仙玉小袋&sign=zs+snU7B3l4Cnec/JWBcXWkFUNWrW1ttEeMZI4X2mtuSNQ9LL9Mri3b6QK0xTc/KMs/Cafk0Ln7iRKQZfnuBvvuaOwVxSgjuWT0ygGktDok0HITE2wKeT8j4SNX4ScIGHLqHXkMojXIZxE6bsfD9kjUb356aFItinf3vURu3FuPSkbJR1KZXDm41hz2rQ9o6Sc3Xs2cr7AbCSVgyGjv5c6G6OiqaXcdgM+FxHtxkhfqB/3awRjXMGmLmWr2m5VyFIfNMOuNCdRN7fNkUBIX3h35KI6av/x6BDYKwTW2zrJHVy91C0h3mrVoDNuRrJ4fPMW2ZH88j7Q3exmPTP0gqMA==&buyer_id=2088002582656381&body=仙玉小袋&invoice_amount=0.01&version=1.0¬ify_id=2020032500222105938056380529774436&fund_bill_list=[{"amount":"0.01","fundChannel":"PCREDIT"}]¬ify_type=trade_status_sync&out_trade_no=TEST171&total_amount=0.01&trade_status=TRADE_SUCCESS&trade_no=2020032522001456380542497258&auth_app_id=2021001144680325&receipt_amount=0.01&point_amount=0.00&buyer_pay_amount=0.01&app_id=2021001144680325&sign_type=RSA2&seller_id=2088031940831575】
2.剔除sign、sign_type参数：
【gmt_create=2020-03-25 10:59:32&charset=utf-8&gmt_payment=2020-03-25 10:59:38¬ify_time=2020-03-25 10:59:38&subject=仙玉小袋&buyer_id=2088002582656381&body=仙玉小袋&invoice_amount=0.01&version=1.0¬ify_id=2020032500222105938056380529774436&fund_bill_list=[{"amount":"0.01","fundChannel":"PCREDIT"}]¬ify_type=trade_status_sync&out_trade_no=TEST171&total_amount=0.01&trade_status=TRADE_SUCCESS&trade_no=2020032522001456380542497258&auth_app_id=2021001144680325&receipt_amount=0.01&point_amount=0.00&buyer_pay_amount=0.01&app_id=2021001144680325&seller_id=2088031940831575】
3、排序：
【app_id=2021001144680325&auth_app_id=2021001144680325&body=仙玉小袋&buyer_id=2088002582656381&buyer_pay_amount=0.01&charset=utf-8&fund_bill_list=[{"amount":"0.01","fundChannel":"PCREDIT"}]&gmt_create=2020-03-25 10:59:32&gmt_payment=2020-03-25 10:59:38&invoice_amount=0.01¬ify_id=2020032500222105938056380529774436¬ify_time=2020-03-25 10:59:38¬ify_type=trade_status_sync&out_trade_no=TEST171&point_amount=0.00&receipt_amount=0.01&seller_id=2088031940831575&subject=仙玉小袋&total_amount=0.01&trade_no=2020032522001456380542497258&trade_status=TRADE_SUCCESS&version=1.0】
三、验签结果：
【验签成功】
校验demo:
from Crypto.PublicKey import RSA from Crypto.Signature import PKCS1_v1_5 import Crypto.Hash.SHA512 from Crypto.Hash import SHA, SHA256 import base64 def rsa2_verify(sign, plaintext, keypath): print(‘*‘ * 100) print(‘sign =‘, sign) with open(keypath) as f: key = f.read() print(‘plaintext =‘, plaintext) hash_value = SHA256.new(plaintext.encode(‘utf-8‘)) print(‘hash_value =‘, hash_value) verifier = PKCS1_v1_5.new(RSA.importKey(key)) # 验证，通过返回true，失败返回false print(‘*‘ * 100) return verifier.verify(hash_value, base64.b64decode(sign)) if __name__ == ‘__main__‘: message = ‘app_id=2021001144680325&auth_app_id=2021001144680325&trade_status=TRADE_SUCCESS&version=1.0‘ publickeyPath = r"H:alipayxnalipay_public.txt" # alipay的公钥 不是app公钥 result = rsa2_verify(signature, message, publickeyPath) print(‘result =‘, result)
