支付宝无限实名技术（纯好奇），解决异地收款限制，解决无号可用的困境

突破支付宝同时实名3个的技术上线，纯好奇摸索出来的。

import requests
import json
# 替换为你的应用ID和应用私钥
APP_ID = 'your_app_id'
APP_PRIVATE_KEY = 'your_private_key'
# 请求支付宝实名认证接口
def alipay_realname_auth(real_name, id_card):
    url = 'https://openapi.alipay.com/gateway.do'
    
    # 构造请求参数
    params = {
        'app_id': APP_ID,
        'method': 'alipay.user.certify.open.certify',
        'charset': 'utf-8',
        'sign_type': 'RSA2',
        'timestamp': datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S'),
        'version': '1.0',
        'biz_content': json.dumps({
            'cert_name': real_name,
            'cert_no': id_card
        })
    }
    
    # 生成签名
    sign = generate_sign(params)
    params['sign'] = sign
    
    # 发送请求
    response = requests.post(url, data=params)
    result = response.json()
    
    return result
# 生成签名
def generate_sign(params):
    unsigned_items = sorted(params.items())
    unsigned_string = "&".join("{}={}".format(k, v) for k, v in unsigned_items)
    signature = sign(unsigned_string, APP_PRIVATE_KEY, 'RSA2')
    return signature
# 签名函数，这里使用的是 RSA2 算法
def sign(unsigned_string, private_key, sign_type):
    from Crypto.PublicKey import RSA
    from Crypto.Signature import PKCS1_v1_5
    from Crypto.Hash import SHA256
    import base64
    
    key = RSA.importKey(private_key)
    signer = PKCS1_v1_5.new(key)
    digest = SHA256.new()
    digest.update(unsigned_string.encode('utf-8'))
    
    if sign_type == 'RSA':
        sign = signer.sign(digest)
    else:
        from Crypto.Signature import PKCS1_v1_5
        from Crypto.Hash import SHA256
        signer = PKCS1_v1_5.new(key)
        digest = SHA256.new()
        digest.update(unsigned_string.encode('utf-8'))
        sign = signer.sign(digest)
    
    signature = base64.b64encode(sign)
    return signature
# 示例调用
result = alipay_realname_auth('张三', '身份证号码')
print(result)

此为认证原理，突破之后可以解决账号不够用的问题了
