如何在Python中打印BTCPay生成的发票的URL及比特币地址？

client.create_invoice()返回的new_invoice是可通过键（或属性）访问的结构，直接定位目标字段即可实现需求：

提取支付页面URL #

直接通过键名获取：

new_invoice = client.create_invoice({"price": 20, "currency": "USD"})
# 打印支付页面URL
print(new_invoice['url'])

如果返回的是对象而非字典，改用点语法：print(new_invoice.url)

提取BIP21对应的比特币地址 #

BIP21信息通常嵌套在paymentMethods下的BTC配置里，逐层访问并增加判断避免报错：

new_invoice = client.create_invoice({"price": 20, "currency": "USD"})
# 提取BIP21地址
if 'paymentMethods' in new_invoice and 'BTC' in new_invoice['paymentMethods']:
    bip21_addr = new_invoice['paymentMethods']['BTC']['bip21']
    print(bip21_addr)
else:
    print("未找到BTC支付方式的BIP21信息")

若返回的是对象，对应写法：

if hasattr(new_invoice, 'paymentMethods') and 'BTC' in new_invoice.paymentMethods:
    print(new_invoice.paymentMethods.BTC.bip21)
