使用支付宝沙箱生成收款码代码实现

好的，以下是使用支付宝沙箱生成收款码的代码实现：

import requests

# 支付宝沙箱接口地址
url = "https://openapi.alipaydev.com/gateway.do"

# 支付宝沙箱应用的APPID
app_id = "你的APPID"

# 支付宝沙箱应用的私钥
app_private_key = """
-----BEGIN RSA PRIVATE KEY-----
你的私钥
-----END RSA PRIVATE KEY-----
"""

# 支付宝沙箱应用的公钥
alipay_public_key = """
-----BEGIN PUBLIC KEY-----
支付宝公钥
-----END PUBLIC KEY-----
"""

# 构建请求参数
params = {
    "app_id": app_id,
    "method": "alipay.marketing.cashlessvoucher.template.create",
    "format": "JSON",
    "charset": "utf-8",
    "sign_type": "RSA2",
    "timestamp": "2022-01-01 00:00:00",
    "version": "1.0",
    "biz_content": {
        "template_name": "测试收款码",
        "voucher_type": "cashless",
        "brand_name": "测试品牌",
        "voucher_desc": "测试描述",
        "publish_start_time": "2022-01-01 00:00:00",
        "publish_end_time": "2023-01-01 00:00:00",
        "use_rule": {
            "use_condition": {
                "suit_shops": {
                    "shop_id": [
                        "001",
                        "002",
                        "003"
                    ]
                }
            }
        }
    }
}

# 生成签名
from urllib.parse import quote_plus
from hashlib import sha256
from base64 import encodebytes
from Crypto.PublicKey import RSA
from Crypto.Signature import PKCS1_v1_5

sign_params = "&".join("{}={}".format(k, quote_plus(str(v))) for k, v in sorted(params.items()))
sign_string = "&".join(["POST", quote_plus("/gateway.do"), quote_plus(sign_params)])
sign_key = RSA.import_key(app_private_key)
signer = PKCS1_v1_5.new(sign_key)
signature = encodebytes(signer.sign(sha256(sign_string.encode("utf-8")))).decode("utf-8").replace("\n", "")

# 发送请求
headers = {
    "Content-Type": "application/json;charset=utf-8",
}
data = {
    **params,
    "sign": signature,
}
response = requests.post(url, headers=headers, json=data)

# 解析响应
import json
response_data = json.loads(response.content.decode("utf-8"))
qr_code = response_data["alipay_cashless_voucher_template_create_response"]["qr_code"]

print(qr_code)

在上面的代码中，我们通过 `alipay.marketing.cashlessvoucher.template.create` 接口创建了一个无需现金支付的优惠券模板，并生成了一个收款码。其中，我们需要将支付宝沙箱应用的APPID、私钥和公钥替换成自己的。

成功执行后，会输出生成的收款码。
